The correct keyword for restricting the records that are returned from a SELECT query based on a supplied criteria for the values in the records is WHERE. The WHERE clause is used to filter records based on one or more conditions. The syntax of the WHERE clause is:
SELECT column1, column2, … FROM table_name WHERE condition;
The condition can be a logical expression that evaluates to true, false, or unknown. The condition can also use comparison operators, logical operators, and wildcards to specify the criteria. For example, the following query selects all the records from the employees table where the salary is greater than 50000:
SELECT * FROM employees WHERE salary > 50000;
The other options are incorrect because they have different purposes in SQL:
LIMIT is used to specify the maximum number of records to return from a query. For example, the following query returns only the first 10 records from the employees table:
SELECT * FROM employees LIMIT 10;
FROM is used to specify the table or tables from which to retrieve data. For example, the following query selects all the columns from the employees table:
SELECT * FROM employees;
IF is used to execute a block of code conditionally. For example, the following query updates the salary of an employee based on their performance:
UPDATE employees SET salary = IF(performance = ‘excellent’, salary * 1.1, salary) WHERE employee_id = 123; References:
