# LOOP

## Syntax

```sql
[begin_label:] LOOP
    statement_list
END LOOP [end_label]
```

## Description

`LOOP` implements a simple loop construct, enabling repeated execution of the statement list, which consists of one or more statements, each terminated by a semicolon (i.e., `;`) statement delimiter. The statements within the loop are repeated until the loop is exited; usually this is accomplished with a [LEAVE](https://mariadb.com/docs/server/reference/sql-statements/programmatic-compound-statements/leave) statement.

A `LOOP` statement can be [labeled](https://mariadb.com/docs/server/reference/sql-statements/programmatic-compound-statements/labels). `end_label` cannot be given unless`begin_label` also is present. If both are present, they must be the same.

See [Delimiters](https://mariadb.com/docs/server/clients-and-utilities/mariadb-client/mariadb-command-line-client#delimiters) in the [mariadb](https://mariadb.com/docs/server/clients-and-utilities/mariadb-client) client for more on delimiter usage in the client.
