## [Description](#Description)

Sends a statement to the server, without waiting for the Server OK packet and/or resultset.

## [Parameters](#Parameters)

•

mysql - a mysql handle, which was previously allocated by [**mysql\_init(3)**](/man/os/mariadb-11.5/mysql_init.3) and connected by [**mysql\_real\_connect(3)**](/man/os/mariadb-11.5/mysql_real_connect.3).

•

query - SQL statement

•

length - length of the SQL statement

## [Notes](#Notes)

•

The OK and result set package need to be retrieved by [**mysql\_read\_query\_result(3)**](/man/os/mariadb-11.5/mysql_read_query_result.3) function

•

mysql\_send\_query() can be used for semi asynchronous operation. While the function itself is blocking, an event driven application can do other tasks until result set is available.
