sql_select_limit

Description

The sql_select_limit variable specifies the maximum number of rows returned by a SELECT statement. If a SELECT statement contains a LIMIT clause, the value of the LIMIT clause has higher priority than that of the sql_select_limit variable. By default, the number of rows returned by a SELECT statement is not limited.
