# mysql\_stmt\_init

## Syntax

```c
MYSQL_STMT * mysql_stmt_init(MYSQL * mysql);
```

## Parameter

* `mysql` - a mysql handle, which was previously allocated by [mysql\_init()](/docs/connectors/mariadb-connector-c/api-functions/mysql_init.md) or [mysql\_real\_connect()](/docs/connectors/mariadb-connector-c/api-functions/mysql_real_connect.md).

## Description

Initializes and allocates memory for a prepared statement.

## Return Value

Returns a pointer to a `MYSQL_STMT` structure or NULL if an error occurred.

{% hint style="info" %}

* Members of the `MYSQL_STMT` structure are not intended for application use`.\`
* A statement handles which was allocated by `mysql_stmt_init()` needs to be freed with [mysql\_stmt\_close()](/docs/connectors/mariadb-connector-c/api-prepared-statement-functions/mysql_stmt_close.md).\\
* Any subsequent calls to any `mysql_stmt` function will fail until [mysql\_stmt\_prepare()](/docs/connectors/mariadb-connector-c/api-prepared-statement-functions/mysql_stmt_prepare.md) was called.
  {% endhint %}
