  • 2. 

    An alternative name that you assign to the table in the query’s FROM clause 

    • Query

    • Table alias

    • Single-row functions

    Correct Answer
    A. Table alias
    Explanation
    A table alias is an alternative name that you assign to a table in a query's FROM clause. This allows you to refer to the table using a shorter or more meaningful name within the query. Table aliases are especially useful when you need to join multiple tables in a query, as they help to clarify which table each column belongs to. By using table aliases, you can make your query more concise and easier to read and understand.

    Removes all of a table’s data without saving any rollback information

    • Roll Back

    • Truncate

    • Single-row functions

    Correct Answer
    A. Truncate
    Explanation
    Truncate is the correct answer because it removes all of a table's data without saving any rollback information. Unlike the delete statement, which can be rolled back, truncate cannot be undone. It is a faster and more efficient way to remove all data from a table when rollback is not necessary.

    Built-in functions that return a single result for each row of data retrieved 

    • Single-row functions

    • Search condition

    • Table alias

    Correct Answer
    A. Single-row functions
    Explanation
    Single-row functions are built-in functions that operate on a single row of data at a time and return a single result for each row. These functions can be used to manipulate data values within a query, perform calculations, or apply transformations to the data. Examples of single-row functions include mathematical functions (such as ABS or ROUND), string functions (such as SUBSTR or CONCAT), and date functions (such as TO_CHAR or MONTH). By applying single-row functions to the retrieved data, we can modify or format the values as needed before displaying or using them further.

    Correct Answer
    A. SYSDATE pseudocolumn
    Explanation
    The SYSDATE pseudocolumn is a single-row function that returns the current date and time. It can be used in SQL queries to retrieve the current date and time and perform calculations or comparisons based on it.

  • 6. 

    A series of action queries that represent a logical unit of work 

    • Query

    • Single Row Function

    • Transaction

    Correct Answer
    A. Transaction
    Explanation
    The correct answer is "Transaction" because a transaction is a series of action queries that represent a logical unit of work. In a transaction, multiple queries are executed together as a single unit, ensuring that either all the queries are successfully executed or none of them are executed. This helps maintain data integrity and consistency in the database.
