% (Wildcard - Character(s) to Match) (Transact-SQL)

Matches any string of zero or more characters. This wildcard character can be used as either a prefix or a suffix. For more information, see Pattern Matching in Search Conditions.

The following example returns all the first names of people in the Contact table of AdventureWorks that start with Dan.

Copy 
USE AdventureWorks;
GO
SELECT FirstName, LastName
FROM Person.Contact
WHERE FirstName LIKE 'Dan%';
GO
