Correct Answer
A. Table aliasExplanation
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.Rate this question:

A. Single-row functionsExplanation
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.Rate this question:

This helps maintain data integrity and consistency in the database.Rate this question:
