## 例

`

     resource mysql_query ( string $query [, resource $link_identifier ] )

`

## 説明

mysql_query() sends a unique query (multiple queries are not supported) to the currently active database on the server that's associated with the specified link_identifier.

## 戻り値

For SELECT, SHOW, DESCRIBE, EXPLAIN and other statements returning resultset, mysql_query() returns a resource on success, or FALSE on error. For other type of SQL statements, INSERT, UPDATE, DELETE, DROP, etc, mysql_query() returns TRUE on success or FALSE on error. The returned result resource should be passed to mysql_fetch_array(), and other functions for dealing with result tables, to access the returned data. Use mysql_num_rows() to find out how many rows were returned for a SELECT statement or mysql_affected_rows() to find out how many rows were affected by a DELETE, INSERT, REPLACE, or UPDATE statement. mysql_query() will also fail and return FALSE if the user does not have permission to access the table(s) referenced by the query.
