SQL LIKE operator

The LIKE operator is used in a WHERE clause to retrieve all records of a table whose specified column values match a specified pattern. The percent sign (%) and underscore (_) are two wildcards used in the LIKE operator pattern. The underscore represents a single character and percent sign represents the multiple characters.

Syntax:

SELECT * FROM tableName WHERE columnName LIKE pattern;

Example:

SELECT * FROM EMPLOYEE WHERE EMP_NAME LIKE 'P%';

Output:

EMP_ID EMP_NAME AGE SALARY 1 Parbhjot 28 35000 5 Parmender 28 45000 4 Parbhjot 29 46000 2 Parmender 28 45000
