# Method Sql.mysql()->big_query()

Method big_query

  ``Mysql.mysql_result` big_query(`string` `query`, `mapping`(`string`|`int`:`mixed`)|`void` `bindings`, `void`|`string` `charset`)`

Description

  Sends a query to the server.

Parameter `query`

  The SQL query.

Parameter `bindings`

  An optional bindings mapping. See Sql.query for details about this.

Parameter `charset`

  An optional charset that will be used temporarily while sending `query` to the server. If necessary, a query

      SET character_set_client=charset

  is sent to the server first, then `query` is sent as-is, and then the connection charset is restored again (if necessary).

  Primarily useful with `charset` set to `"latin1"` if unicode encode mode (see set_unicode_encode_mode) is enabled (the default) and you have some large queries (typically blob inserts) where you want to avoid the query parsing overhead.

Returns

  A Mysql.mysql_result object is returned if the query is of a kind that returns a result. Zero is returned otherwise.

  The individual fields are returned as strings except for `NULL`, which is returned as UNDEFINED.
