A predicate is an expression that evaluates to TRUE, FALSE, or UNKNOWN. Predicates are used in the search condition of WHERE clauses and HAVING clauses, the join conditions of FROM clauses, and other constructs where a Boolean value is required.

For more information, including how to specify a search condition, see Search condition.

SQL Server provides the following predicates:

• CONTAINS (Transact-SQL)
