# 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 %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mariadb.com/docs/connectors/mariadb-connector-c/api-prepared-statement-functions/mysql_stmt_init.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
