The LIKE operator is used in a WHERE clause to search for a specified pattern in a column using wildcard characters. It uses two wildcards - the percent sign (%) to match any substring and the underscore (_) to match a single character. The percent sign can match any substring, while the underscore matches any single character. Examples show how the LIKE operator with wildcards can be used to search for names starting with "a" or containing "s_ _ _" in a table.

2. LIKE Operator
The LIKE operator is used in a WHERE clause to search for a
specified pattern in a column.
The LIKE keyword is used to select rows containing columns
that match a wildcard pattern.
There are two wildcards
1. Percent ( % )
2. Underscore ( _ )

3. Percent ( % )
Syntax:
SELECT * / columnnames
FROM table_name
WHERE columnname
Like “%character%” ;
The percent sign represents multiple characters.
The % character matched any substring.
Example:
SELECT *
FROM Employee
WHERE names
Like “ a%” ;

6. Underscore ( _ )
Syntax:
SELECT * / columnnames
FROM table_name
WHERE columnname
Like “_ character _” ;
The underscore represents a single character.
The _ character matches any character.
Example:
SELECT *
FROM Employee
WHERE names
Like “ s_ _ _” ;

8. Combination Of both Operator
Syntax:
SELECT * / columnnames
FROM table_name
WHERE columnname
Like “%_character_ %”
We can use both operator in MySql Query
Example:
SELECT *
FROM Employee
WHERE names
Like “ _a%a_” ;
