What type of join is needed when you wish to return rows that do have matching values?
-
Natural join
-
Close out
-
Low join
-
Open join
Correct Answer
A. Natural joinExplanation
A natural join is needed when you wish to return rows that have matching values. This type of join combines rows from two tables based on the columns that have the same name and data type in both tables. It automatically matches the values in these columns and returns only the rows that have matching values.Rate this question:

What type of join is needed when you wish to include rows that do not have matching values?
-
Outer join
-
Inner join
-
Natural join
-
Equal join
Correct Answer
A. Outer joinExplanation
An outer join is needed when you wish to include rows that do not have matching values. Unlike an inner join which only includes matching rows, an outer join includes all rows from one table and the matching rows from the other table. If there is no match, null values are included for the columns from the other table. This allows you to include all the data from one table, even if there are no matching values in the other table.Rate this question:

What kind of query uses the result of an outer query to determine the processing of an inner query?
-
Correlated subquery
-
Inner query
-
Random query
-
Inner subquery
Correct Answer
A. Correlated subqueryExplanation
A correlated subquery is a type of query that uses the result of an outer query to determine the processing of an inner query. In other words, the inner query is dependent on the values from the outer query in order to execute. This allows the subquery to be evaluated for each row of the outer query, making it useful for situations where you need to compare values between the outer and inner queries.Rate this question:

A CASE SQL statement is used to establish...
-
IF-THEN-SAVE
-
IF-THEN-DEFINE
-
IF-THEN-RUN
-
IF-THEN-ELSE
Correct Answer
A. IF-THEN-ELSEExplanation
The correct answer is "IF-THEN-ELSE". In SQL, the CASE statement is used to establish conditional logic. It allows you to perform different actions based on different conditions. The syntax for the CASE statement includes the keywords IF-THEN-ELSE, where you specify the condition to be evaluated in the IF part, the action to be taken if the condition is true in the THEN part, and the action to be taken if the condition is false in the ELSE part.Rate this question:

Which of these is a feature of triggers?
-
Row
-
Potential
-
Line
-
Action
Correct Answer
A. ActionExplanation
Triggers are database objects that are associated with a table and are automatically executed or fired when a specific event occurs, such as an insert, update, or delete operation on the table. The feature of triggers is that they perform a specific action or set of actions in response to the occurrence of the specified event. Therefore, "Action" is the correct answer as it accurately describes one of the key features of triggers.Rate this question:

A feature of triggers is...
-
Lineup
-
Memory
-
Condition
-
Query
Correct Answer
A. ConditionExplanation
A feature of triggers is "Condition". Triggers are used in programming to specify a set of actions that should be executed when a specific event occurs. The condition in a trigger determines when the trigger should be activated. It acts as a criteria or requirement that needs to be met for the trigger to be triggered. The condition can be based on various factors such as data values, time, or user actions. By using conditions, triggers can be customized to respond to specific circumstances and perform the desired actions accordingly.Rate this question:

Which of the following statements is true concerning routines and triggers?
-
Both run alongside codes
-
One is an operator
-
Both consist of procedural code
-
Both run automatically
Correct Answer
A. Both consist of procedural codeExplanation
Both routines and triggers consist of procedural code. Routines are a set of instructions that can be called and executed at any time, while triggers are special types of routines that are automatically executed in response to specific events or actions in a database. In both cases, the code within the routine or trigger is written in a procedural programming language, such as SQL or PL/SQL, to perform a specific task or set of tasks. Therefore, the statement that both consist of procedural code is true.Rate this question:
