Returns: A positive MS SQL result identifier on success,
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.
