SQL LIKE Operator

SQL LIKE Operator Referance

The LIKE operator is used to search for a specified pattern in a column.

SQL LIKE Syntax

SELECT column_name(s)
FROM table_name
WHERE column_name LIKE pattern;

The following SQL statement selects all customers with a City starting with the letter “s”:
Example
SELECT * FROM Customers
WHERE City LIKE ‘s%’;
Tip: The “%” sign is used to define wildcards (missing letters) both before and after the pattern. You will learn more about wildcards in the next chapter.

The following SQL statement selects all customers with a City ending with the letter “s”:
Example
SELECT * FROM Customers
WHERE City LIKE ‘%s’;

The following SQL statement selects all customers with a Country containing the pattern “land”:
Example
SELECT * FROM Customers
WHERE Country LIKE ‘%land%’;

Using the NOT keyword allows you to select records that does NOT match the pattern.
The following SQL statement selects all customers with a Country NOT containing the pattern “land”:
Example
SELECT * FROM Customers
WHERE Country NOT LIKE ‘%land%’;
