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
