# mysql\_fetch\_field\_direct

## Syntax

```c
MYSQL_FIELD * mysql_fetch_field_direct(MYSQL_RES * res,
                                       unsigned int fieldnr);
```

## Parameters

* `res` - a result set identifier returned by [mysql\_store\_result()](/docs/connectors/mariadb-connector-c/api-functions/mysql_store_result.md) or [mysql\_use\_result()](/docs/connectors/mariadb-connector-c/api-functions/mysql_use_result.md).
* `fieldnr` - the field number. This value must be within the range from 0 to number of fields - 1

## Description

Returns a pointer to a `MYSQL_FIELD` structure which contains field information from the specified result set.

## Return Value

Pointer to a `MYSQL_FIELD` structure. The caller must ensure that `fieldnr` is less than `mysql_field_count()`; specifying an out-of-range value results in undefined behavior, not a `NULL` return.

{% hint style="info" %}
The total number of fields can be obtained by `mysql_field_count()`.
{% endhint %}
