To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Determines if a value matches any of the values in a list or a sub-query - This option is correct. The IN
keyword is used in SQL to determine if a value matches any of the values in a list or a sub-query. It is typically used in the WHERE
clause of a query to specify a condition.
Option B) Defines the tables we are selecting or deleting data from - This option is incorrect. The FROM
keyword is used to define the tables we are selecting or deleting data from in SQL.
Option C) Is used with the DISTINCT SQL keyword only - This option is incorrect. The IN
keyword is not specifically used with the DISTINCT
keyword. The IN
keyword can be used with any other SQL keyword or clause.
Option D) Is used to select data from a view - This option is incorrect. The IN
keyword is not specifically used to select data from a view. It is used to compare a value with a list of values or the result of a sub-query.
The correct answer is Option A. The IN
keyword in SQL is used to determine if a value matches any of the values in a list or a sub-query.
