( string query [, resource link_identifier [, int batch_size]] )
Returns: A MS SQL result resource on success, TRUE if no
rows were returned, or FALSE on error.
mssql_query() sends a query to the currently
active database on the server that's associated with the
specified link identifier. If the link identifier isn't
specified, the last opened link is assumed. If no link is open,
the function tries to establish a link as if
mssql_connect() was called, and use it.
