+# LIKE and RLIKE operators [sql-like-rlike-operators]
 
 `LIKE` and `RLIKE` operators are commonly used to filter data based on string patterns. They usually act on a field placed on the left-hand side of the operator, but can also act on a constant (literal) expression. The right-hand side of the operator represents the pattern. Both can be used in the `WHERE` clause of the `SELECT` statement, but `LIKE` can also be used in other places, such as defining an [index pattern](/reference/query-languages/sql/sql-index-patterns.md) or across various [SHOW commands](/reference/query-languages/sql/sql-commands.md). This section covers only the `SELECT ... WHERE ...` usage.
