(PHP 3, PHP 4 , PHP 5)

msql_query -- Send mSQL query

## Description

resource msql_query ( string query [, resource link_identifier])

msql_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 msql_connect() was called, and use it.

Returns a positive mSQL query identifier on success, or `FALSE` on error.
