If DBResult:dbhandle is a valid handle, it returns 1, otherwise 0 if DBResult:dbhandle is a NULL reference.

## ตัวอย่าง

```c
// Example function
GetNameBySpawnID(spawn_id)
{
    // Declare "p_name"
    new p_name[MAX_PLAYER_NAME + 1];

    // Declare "query" and "db_result"
    static query[60], DBResult:db_result;

    // Formats "query"
    format(query, sizeof query, "SELECT `PlayerName` FROM `spawn_log` WHERE `ID`=%d", spawn_id);

    // Selects the player name by using "spawn_id"
    db_result = db_query(db_handle, query);

    // If there is any valid entry
    if (db_num_rows(db_result))
    {
        // Store data from "PlayerName" into "p_name"
        db_get_field(db_result, 0, p_name, sizeof p_name);
    }

    // Frees the result
    db_free_result(db_result);

    // Returns "p_name"
    return p_name;
}
