Which type of argument passes a value from a procedure to the calling environment?
- VARCHAR2
- BOOLEAN
- OUT
- IN
Correct Answer

A. OUT

Explanation

The type of argument that passes a value from a procedure to the calling environment is the OUT argument. When a procedure has an OUT argument, it means that the procedure will modify the value of the argument and pass it back to the calling environment. This allows the procedure to return a value or multiple values to the caller.

You create a DML trigger. For the timing information, which are valid with a DML trigger? (Choose all that apply)
- DURING
- IN PLACE OF
- ON SHUTDOWN
- BEFORE
- ON STATEMENT EXECUTION
Correct Answer

A. BEFORE

Explanation

BEFORE is a valid timing option for a DML trigger. It specifies that the trigger should be executed before the DML operation is performed. This allows the trigger to modify the data before it is inserted, updated, or deleted. DURING, IN PLACE OF, ON SHUTDOWN, and ON STATEMENT EXECUTION are not valid timing options for a DML trigger.

Which code can you use to ensure that the salary is not increased by more than 10% at a time nor is it ever decreased?
- ALTER TABLE emp ADD CONSTRAINT ck_sal CHECK (sal BETWEEN sal AND sal*1.1);
- CREATE OR REPLACE TRIGGER check_sal BEFORE UPDATE OF sal ON emp FOR EACH ROW WHEN (new.sal < old.sal OR new.sal > old.sal * 1.1) BEGIN RAISE_APPLICATION_ERROR ( - 20508, 'Do not decrease salary not increase by more than 10%'); END;
- CREATE OR REPLACE TRIGGER check_sal BEFORE UPDATE OF sal ON emp WHEN (new.sal < old.sal OR new.sal > old.sal * 1.1) BEGIN RAISE_APPLICATION_ERROR ( - 20508, 'Do not decrease salary not increase by more than 10%'); END;
- CREATE OR REPLACE TRIGGER check_sal AFTER UPDATE OR sal ON emp WHEN (new.sal < old.sal OR -new.sal > old.sal * 1.1) BEGIN RAISE_APPLICATION_ERROR ( - 20508, 'Do not decrease salary not increase by more than 10%'); END;
Correct Answer

A. CREATE OR REPLACE TRIGGER check_sal BEFORE UPDATE OF sal ON emp FOR EACH ROW WHEN (new.sal < old.sal OR new.sal > old.sal * 1.1) BEGIN RAISE_APPLICATION_ERROR ( - 20508, 'Do not decrease salary not increase by more than 10%'); END;

Explanation

Row triggers are the correct chose for solving the problem. A row trigger fires each time the table is affected by the triggering event. If the triggering event affects no rows, a row trigger is not executed. Row triggers are useful if the trigger action depends on data of rows that are affected or on data provided by the triggering event itself. You can create a BEFORE row trigger in order to prevent the triggering operation from succeeding if a certain condition is violated. Within a ROW trigger, reference the value of a column before and after the data change by prefixing it with the OLD and NEW qualifier. Incorrect Answers:
A: Check constaint can't do this job lets take a look:
SQL> ALTER TABLE emp ADD
2 CONSTRAINT ck_sal CHECK (sal BETWEEN sal AND sal*1.1)

3 /
Table altered.
SQL> select ename, sal
2 from emp
3 where ename = 'KING';
ENAME SAL

KING 5000 Now let's issue an update statement SQL> update emp 2 set sal = 10 3 where ename = 'KING'; 1 row updated. As you can see the check constraint can't compare the old value with the new value. D,C: You can use NEW and OLD qualifier with row level triggers, If in the CREATE TRIGGER statement you didn't say FOR EACH ROW then the trigger will be statement level trigger

Which statement is valid when removing procedures?
- Use a drop procedure statement to drop a standalone procedure.
- Use a drop procedure statement to drop a procedure that is part of a package. Then recompile the package specification.
- Use a drop procedure statement to drop a procedure that is part of a package. Then recompile the package body
- For faster removal and re-creation, do not use a drop procedure statement. Instead, recompile the procedure using the alter procedure statement with the REUSE SETTINGS clause.
Correct Answer

A. Use a drop procedure statement to drop a standalone procedure.

Explanation

The DROP DROCEDURE statement is used to drop a stand alone procedure Incorrect Answers:
B: You can't drop a procedure that's inside a package, you have to drop the package, and in this case the whole procedures, functions,... that are inside the packages will be droped.
C: Same as B.
D: REUSE SETTINGS is used to to prevent Oracle from dropping and reacquiring compiler switch settings.With this clause, Oracle preserves the existing settings and uses them for the recompilation.

Examine this code: CREATE OR REPLACE TRIGGER update_emp AFTER UPDATE ON emp BEGIN INSERT INTO audit_table (who, dated) VALUES (USER, SYSDATE); END; You issue an UPDATE command in the EMP table that results in changing 10 rows. How many rows are inserted into the AUDIT_TABLE?
- 1
- 10
- None
- A value equal to the number of rows in the EMP table
Correct Answer

A. 1

Explanation

The code creates a trigger named "update_emp" that fires after an update operation on the "emp" table. The trigger inserts a single row into the "audit_table" with the current user and the current date. Therefore, regardless of the number of rows updated in the "emp" table, only one row will be inserted into the "audit_table".

- ALTER TABLE employees DISABLE ALL TRIGGERS;
Correct Answer

A. ALTER TABLE employees DISABLE ALL TRIGGERS;

Explanation

The correct answer is "ALTER TABLE employees DISABLE ALL TRIGGERS;". This command specifically targets the EMPLOYEES table and disables all triggers associated with it. The other options are incorrect because they either do not target the table or do not disable all triggers.

CREATE OR REPLACE PACKAGE discounts IS G_ID NUMBER:=7839; DISCOUNT_RATE NUMBER 0. 00; PROCEDURE DISPLAY_PRICE (V_PRICE NUMBER); END DISCOUNTS; / CREATE OR REPLACE PACKAGE BODY discounts IS PROCEDURE DISPLAY_PRICE (V_PRICE_NUMBER) 12 IS BEGIN DBMS_OUTPUT.PUT_LINE(‘DISCOUNTED||2_4 (V_PRICE*NVL(DISCOUNT_RATE, 1))) END DISPLAY_PRICE; BEGIN DISCOUNT_RATE;=0. 10; END DISCOUNTS; / Which statement is true?
- The value of DISCOUNT_RATE always remain 0. 00 in a session.
- The value of DISCOUNT_RATE is set to 0. 10 each time the package are invoked in a session.
- The value of DISCOUNT_RATE is set to 1 each time the procedure DISPLAY_PRICE is invoked.
- The value of DISCOUNT_RATE is set to 0. 10 when the package is invoked for first time in a session.
Correct Answer

A. The value of DISCOUNT_RATE is set to 0. 10 when the package is invoked for first time in a session.

Explanation

The correct answer is that the value of DISCOUNT_RATE is set to 0.10 when the package is invoked for the first time in a session. This can be inferred from the code in the package body where DISCOUNT_RATE is assigned the value of 0.10 within the BEGIN-END block. This means that every time the package is invoked for the first time in a session, the value of DISCOUNT_RATE will be set to 0.10.

- SELECT CALC_PLAYER_AVG(PLAYER_ID) FROM PLAYER_BAT_STAT;
- EXECUTE CALC_PLAYER_AVG(31);
- CALC_PLAYER('RUTH');
- CALC_PLAYER_AVG(31);
- START CALC_PLAYER_AVG(31)
Correct Answer

A. SELECT CALC_PLAYER_AVG(PLAYER_ID) FROM PLAYER_BAT_STAT;

Explanation

B. You can't call a function in this way, in this way you can call a procedure, because function must return a value, to call a function using EXECUTE command you should declare a bind variable using the VARIABLE command then assign the value returned from the function to this variable, in the following way: SQL> VARIABLE v_get_value NUMBER SQL> EXECUTE :v_get_value := CALC_PLAYER_AVG(31) PL/SQL procedure successfully completed. SQL> PRINT v_get_value V_GET_VALUE
C. Again this way can't be use for calling a function in PL/SQL block because the function return a value and this values must be assigned to PL/SQL variable or to bind variable. Like this DECLARE v_get_from_fn NUMBER; BEGIN v_get_from := CALC_PLAYER_AVG(31); END; 1z0-147 /

- EMP_ID LOG_DATE NEW_SALARY ACTION ---------- -------- ---------- ---------- 201 24-SEP-02 13000 NEW SAL 202 24-SEP-02 600 NEW SAL
- EMP_ID LOG_DATE NEW_SALARY ACTION ---------- -------- ---------- ---------- 201 24-SEP-02 14000 NEW SAL 202 24-SEP-02 7000 NEW SAL
- C. EMP_ID LOG_DATE NEW_SALARY ACTION ---------- -------- ---------- ---------- 201 24-SEP-02 NEW SAL 202 24-SEP-02 NEW SAL
- No rows are inserted.
Correct Answer

A. EMP_ID LOG_DATE NEW_SALARY ACTION ---------- -------- ---------- ---------- 201 24-SEP-02 14000 NEW SAL 202 24-SEP-02 7000 NEW SAL

Explanation

The trigger "Log_salary_increase" is created to insert a new row into the "Emp_log" table whenever there is an update on the "employees" table and the new salary is greater than 1000.0. In the given SQL statement, the condition "Where Department_id = 20M" is incorrect as it should be "Where Department_id = 20". Therefore, the SQL statement will not update any rows in the "employees" table, resulting in no rows being inserted into the "Emp_log" table.

Debug the logic in a stored procedure. How do you monitor the value of variables in the procedure using SQL Plus environment?
- INSERT TEXT_IO.PUT_LINE statement to view data on the screen when the stored procedure is executed.
- Insert break points in the code and observe the variable values displayed to the screen as the procedure is executed.
- Insert DBMS_OUTPUT.PUT_LINE statement to view data on the screen when the stored procedure is executed
- Insert DEBUG VARIABLE statements to view the variable values on the screen as the procedure is executed.
Correct Answer

A. Insert DBMS_OUTPUT.PUT_LINE statement to view data on the screen when the stored procedure is executed

Explanation

To monitor the value of variables in a stored procedure using SQL Plus environment, you can insert DBMS_OUTPUT.PUT_LINE statement in the code. This statement will display the data on the screen when the stored procedure is executed. By including this statement at various points in the code, you can track the values of variables as the procedure is executed, helping you debug the logic and identify any issues.

Explanation

A is correct because both of the parameter have a default values.
B is correct because here we call the procedure using position notation, and the first parameter for the procedure will have the value 'Accounting', and since the second parameter has a default value then we can skip it, and in this case it will take the default value.

- Employee 108 has his email name updated based on the return result of the function.
- The statement fails because functions called from SQL expressions cannot perform DML.
- The statement fails because the functions does not contain code to end the transaction.
- The SQL statement executes successfully, because UPDATE and DELETE statements are ignoring in stored functions called from SQL expressions.
- The SQL statement executes successfully and control is passed to the calling environment
Correct Answer

A. The statement fails because functions called from SQL expressions cannot perform DML.

Explanation

When called from a SELECT statement or a parallelized UPDATE or DELETE statement, the function cannot modify any database tables
When called from an UPDATE, or DELETE statement, the function cannot query or modify any database tables modified by that statement.
When called from a SELECT, INSERT, UPDATE, or DELETE statement, the function cannot execute SQL transaction control statements (such as COMMIT), session control statements (such as SET ROLE), or system control statements (such as ALTER SYSTEM). Also, it cannot execute DDL statements (such as CREATE) because they are followed by an automatic commit.
The function cannot call another subprogram that breaks one of the above restrictions.

You have a row level BEFORE UPDATE trigger on the EMP table. This trigger contains a SELECT statement on the EMP table to ensure that the new salary value falls within the minimum and maximum salary for a given job title. What happens when you try to update a salary value in the EMP table?
- The trigger fires successfully.
- The trigger fails because it needs to be a row level AFTER UPDATE trigger.
- The trigger fails because a SELECT statement on the table being updated is not allowed.
- The trigger fails because you cannot use the minimum and maximum functions in a BEFORE UPDATE trigger.
Correct Answer

A. The trigger fails because a SELECT statement on the table being updated is not allowed.

Explanation

When you try to update a salary value in the EMP table, the trigger fails because a SELECT statement on the table being updated is not allowed. In other words, you cannot perform a SELECT operation on the same table that is being updated in a trigger.

- If you remove the stand alone stored function CALC_HEIGHT, then the METRIC_CONVERTER package body and the package specification are removed. /The stand alone function CALC_HEIGHT cannot be created because its name is used in a packaged function.
Correct Answer

A. If you remove the package specification, then the package body is removed.

Explanation

If you remove the package specification, then the package body is removed. This means that if the package specification is deleted, both the package body and the stand-alone stored function CALC_HEIGHT will be removed as well. The package specification serves as the interface for the package, defining the public elements, while the package body contains the implementation of those elements. Removing the package specification effectively removes the entire package.

Examine the trigger heading: CREATE OR REPLACE TRIGGER salary_check BEFORE UPDATE OF sal, job ON emp FOR EACH ROW Under which condition does this trigger fire?
- When a row is inserted into the EMP table.
- When the value of the SAL or JOB column in a row is updated in the EMP table.
- When any column other than the SAL and JOB columns in a row are updated in the EMP table.
- Only when both values of the SAL and JOB columns in a row are updated together in the EMP table.
Correct Answer

A. When the value of the SAL or JOB column in a row is updated in the EMP table.

Explanation

The trigger fires when the value of either the SAL or JOB column in a row is updated in the EMP table. It does not matter if any other columns are updated or if both the SAL and JOB columns are updated together. The trigger will still fire as long as either the SAL or JOB column is updated.

Examine this procedure: CREATE OR REPLACE PROCEDURE UPD_BAT_STAT (V_ID IN NUMBER DEFAULT 10, V_AB IN NUMBER DEFAULT 4) IS BEGIN UPDATE PLAYER_BAT_STAT SET AT_BATS = AT_BATS + V_AB WHERE PLAYER_ID = V_ID; COMMIT; END; Which two statements will successfully invoke this procedure in SQL *Plus? (Choose two)
- EXECUTE UPD_BAT_STAT;
- EXECUTE UPD_BAT_STAT(V_AB=>10, V_ID=>31);
- EXECUTE UPD_BAT_STAT(31, 'FOUR','TWO');
- UPD_BAT_STAT(V_AB=>10, V_ID=>31);
- RUN UPD_BAT_STAT
Correct Answer(s)

A. EXECUTE UPD_BAT_STAT;
A. EXECUTE UPD_BAT_STAT(V_AB=>10, V_ID=>31);

Explanation

The procedure UPD_BAT_STAT is created with two input parameters, V_ID and V_AB, with default values of 10 and 4 respectively. The procedure updates the AT_BATS column in the PLAYER_BAT_STAT table, adding the value of V_AB to the existing value, for the row where PLAYER_ID matches V_ID. It then commits the changes.

To successfully invoke this procedure in SQL *Plus, the EXECUTE command is used. The first statement, EXECUTE UPD_BAT_STAT;, will invoke the procedure with the default values for V_ID and V_AB. The second statement, EXECUTE UPD_BAT_STAT(V_AB=>10, V_ID=>31);, will invoke the procedure with specific values for V_ID and V_AB.

- The trigger records an audit trail when a user makes changes to the database.
- The trigger marks the user as logged on to the database before an audit statement is issued.
- The trigger invoked the procedure audit_action each time a user logs on to his/her schema and adds the username to the audit table.
- The trigger invokes the procedure audit_action each time a user logs on to the database and adds the username to the audit table.
Correct Answer

A. The trigger invokes the procedure audit_action each time a user logs on to the database and adds the username to the audit table.

Explanation

The given trigger invokes the procedure audit_action every time a user logs on to the database and adds the username to the audit table. This means that whenever a user logs in, their username will be recorded in the audit table, creating an audit trail of user logins.

Which view displays indirect dependencies, indenting each dependency?
- DEPTREE
- IDEPTREE
- INDENT_TREE
- I_DEPT_TREE
Correct Answer

A. IDEPTREE

Explanation

The correct answer is IDEPTREE. IDEPTREE view displays indirect dependencies by indenting each dependency. This means that it shows the hierarchical relationship between dependencies, making it easier to understand the dependencies of a particular item.

Examine the trigger: CREATE OR REPLACE TRIGGER Emp_count AFTER DELETE ON Emp_tab FOR EACH ROW DELCARE n INTEGER; BEGIN SELECT COUNT(*) INTO n FROM Emp_tab; DBMS_OUTPUT.PUT_LINE(' There are now ' || a || ' employees,'); END; This trigger results in an error after this SQL statement is entered: DELETE FROM Emp_tab WHERE Empno = 7499; How do you correct the error?
- Change the trigger type to a BEFORE DELETE
- Take out the COUNT function because it is not allowed in a trigger
- Remove the DBMS_OUTPUT statement because it is not allowed in a trigger.
- Change the trigger to a statement-level trigger by removing FOR EACH ROW
Correct Answer

A. Change the trigger to a statement-level trigger by removing FOR EACH ROW

Explanation

Removing the "FOR EACH ROW" clause will change the trigger to a statement-level trigger. In a statement-level trigger, the trigger fires once for each SQL statement, rather than for each row affected by the statement. This change will correct the error because the trigger is currently expecting to work with individual rows, but the DELETE statement is affecting multiple rows at once. By making the trigger a statement-level trigger, it will be able to handle the DELETE statement correctly.

An internal LOB is _____.
- A table.
- A column that is a primary key.
- Stored in the database.
- A file stored outside of the database, with an internal pointer to it from a database column.
Correct Answer

A. Stored in the database.

Explanation

An internal LOB refers to a Large Object that is stored within the database. It can be any type of data such as text, images, or videos that are too large to be stored in a regular table column. Storing the LOB in the database allows for efficient management and retrieval of the data, as it is directly accessible through the database system.

Under which two circumstances do you design database triggers? (Choose two)
- To duplicate the functionality of other triggers
- To replicate built-in constraints in the Oracle server such as primary key and foreign key.
- To guarantee that when a specific operation is performed, related actions are performed.
- For centralized, global operations that should be fired for the triggering statement, regardless of which user or application issues the statement.
Correct Answer(s)

A. To guarantee that when a specific operation is performed, related actions are performed.
A. For centralized, global operations that should be fired for the triggering statement, regardless of which user or application issues the statement.

Explanation

Database triggers are designed under two circumstances:
1) To guarantee that when a specific operation is performed, related actions are performed. This means that when a certain event or action occurs in the database, the trigger will automatically execute a set of predefined actions or procedures.
2) For centralized, global operations that should be fired for the triggering statement, regardless of which user or application issues the statement. This means that the trigger is designed to execute a specific action or set of actions whenever a particular statement is issued, regardless of who or what issues the statement.

Which two statements about packages are true? (Choose two)
- Packages can be nested.
- You can pass parameters to packages.
- A package is loaded into memory each time it is invoked
- The contents of packages can be shared by many applications.
- You can achieve information hiding by making package constructs private
Correct Answer(s)

A. The contents of packages can be shared by many applications.
A. You can achieve information hiding by making package constructs private

Explanation

Actually theses are some of the advantages of the package, sharing the package among applications and
hide the logic of the procedures and function that are inside the package by declaring them in the package
header and write the code of these procedures and functions inside the package body.
Incorrect Answers:

A: Packages can not be nested
B: Parameters can't be passed to a package; parameters can be passed to procedures and functions only.
C: By the first time you call a procedure, function, or reference a global variable within the package, the whole package will be loaded into the memory and stay there, so when ever you need to reference any of the package's constructs again you will find it in the memory

- You need to execute the command CALCTAX(1000);.
- You need to execute the command EXECUTE FUNCTION calctax;.
- You need to create a SQL *Plus environment variable X and issue the command :X := CALCTAX(1000);.
- You need to create a SQL *Plus environment variable X and issue the command EXECUTE :X := CALCTAX;
- You need to create a SQL *Plus environment variable X and issue the command EXECUTE :X := CALCTAX(1000);
Correct Answer

A. You need to create a SQL *Plus environment variable X and issue the command EXECUTE :X := CALCTAX(1000);

Explanation

When you call a function from SQL*PLUS you need to assign the returned value a bind variable, and you need the EXECUTE command to execute the function

Which statement about triggers is true?
- You use an application trigger to fire when a DELETE statement occurs
- You use a database trigger to fire when an INSERT statement occurs
- You use a system event trigger to fire when an UPDATE statement occurs.
- You use INSTEAD OF trigger to fire when a SELECT statement occurs
Correct Answer

A. You use a database trigger to fire when an INSERT statement occurs

Explanation

A database trigger is a stored procedure that automatically executes when a specific event occurs within a database. In this case, the trigger is set to fire when an INSERT statement occurs, meaning that whenever a new record is inserted into the database, the trigger will be activated and execute the specified actions. This allows for automated processes or validations to be performed whenever new data is added to the database.

Examine this procedure: CREATE OR REPLACE PROCEDURE INSERT_TEAM(V_ID in NUMBER, V_CITY in VARCHAR2 DEFAULT 'AUSTIN', V_NAME in VARCHAR2) IS BEGIN INSERT INTO TEAM (id, city, name) VALUES (v_id, v_city, v_name); COMMIT; END Which two statements will successfully invoke this procedure in SQL *Plus? (Choose two)
- EXECUTE INSERT_TEAM;
- EXECUTE INSERT_TEAM(3, V_NAME=>'LONGHORNS', V_CITY=>'AUSTIN');
- EXECUTE INSERT_TEAM(3, 'AUSTIN','LONGHORNS');
- EXECUTE INSERT_TEAM (V_ID := V_NAME := 'LONGHORNS', V_CITY := 'AUSTIN');
- EXECUTE INSERT_TEAM (3, 'LONGHORNS');
Correct Answer(s)

A. EXECUTE INSERT_TEAM(3, V_NAME=>'LONGHORNS', V_CITY=>'AUSTIN');
A. EXECUTE INSERT_TEAM(3, 'AUSTIN','LONGHORNS');

Explanation

The procedure INSERT_TEAM has three parameters: V_ID, V_CITY, and V_NAME. The first statement EXECUTE INSERT_TEAM(3, V_NAME=>'LONGHORNS', V_CITY=>'AUSTIN') successfully invokes the procedure by passing the values 3, 'LONGHORNS', and 'AUSTIN' to the respective parameters. The second statement EXECUTE INSERT_TEAM(3, 'AUSTIN','LONGHORNS') also successfully invokes the procedure by passing the values 3, 'AUSTIN', and 'LONGHORNS' to the respective parameters.

When creating a function, in which section will you typically find the RETURN keyword?
- HEADER only
- DECLARATIVE
- EXECUTABLE and HEADER
- DECLARATIVE,EXECUTABLE and EXCEPTION HANDLING
Correct Answer

A. EXECUTABLE and HEADER

Explanation

The RETURN keyword is typically found in the EXECUTABLE section and the HEADER section when creating a function. The EXECUTABLE section contains the code that is executed when the function is called, and the RETURN keyword is used to specify the value that the function will return. The HEADER section contains the function declaration, including the return type of the function. Therefore, both sections are necessary for the presence of the RETURN keyword.

The BB_PACK body is recompiled. What happens if the stand alone procedure VALIDATE_PLAYER_STAT references this package?
- VALIDATE_PLAYER_STAT cannot recompile and must be recreated
- VALIDATE_PLAYER_STAT is not invalidated
- VALDIATE_PLAYER_STAT is invalidated
- VALIDATE_PLAYER_STAT and BB_PACK are invalidated
Correct Answer

A. VALIDATE_PLAYER_STAT is not invalidated

Explanation

You can greatly simplify dependency management with packages when referencing a package procedure or function from a stand-alone procedure or function.
If the package body changes and the package specification does not change, the stand-alone procedure referencing a package construct remains valid.
If the package specification changes, the outside procedure referencing a package construct is invalidated, as is the package body

- An statement is not allowed in a subprogram declaration
- Procedure LOG_EXEC should be declared before any identifiers.
- Variable v_name should be declared before declaring the LOG_EXEC procedure
- The LOG_EXEC procedure should be invoked as EXECUTE log_exec with the AUDIT_EMP procedure.
Correct Answer

A. Variable v_name should be declared before declaring the LOG_EXEC procedure

Explanation

The code causes an error when compiled because the variable v_name is referenced before it is declared. In the code, the LOG_EXEC procedure is invoked before the declaration of v_name, causing the error. To fix this, the variable v_name should be declared before declaring the LOG_EXEC procedure.

Which one is the correct routine for the utilization order when using dynamic SQL?
- Open, Parse, Bind, Execute, Fetch, Close
- Parse, Bind, open, Execute, Close, Fetch
- Bind, Open, Parse, Execute, Fetch, Close
- Open, Bind, Parse, Execute, Close, Fetch
Correct Answer

A. Open, Parse, Bind, Execute, Fetch, Close

Explanation

The correct routine for the utilization order when using dynamic SQL is to first open the connection, then parse the SQL statement, bind the variables, execute the statement, fetch the results, and finally close the connection. This order ensures that the connection is established before processing the SQL statement, and that the necessary variables are bound and results are fetched in the correct order.

1 Initialize the variable within its declaration or within an automatic, one-time-only procedure.
2 Change the value of the variable by means of package procedures.
3 The value of the variable is released when the user disconnects. Incorrect Answers

B: Each session will have its own value for the variables
C: It persists across the transactions and through the user session.
D: Each user has his own values and results, because each user has his own users.
