Description
resource
mysql_db_query ( string database, string query [, resource link_identifier])
Returns a positive MySQL result resource to the query result,
or FALSE on error. The function also returns TRUE/FALSE for
INSERT/UPDATE/DELETE
queries to indicate success/failure.
mysql_db_query() selects a database and
executes a query on it. If the optional link identifier isn't
specified, the function will try to find an open link to the
MySQL server and if no such link is found it'll try to create one
as if mysql_connect() was called with no
arguments.
Be aware that this function does NOT
switch back to the database you were connected before. In other words,
you can't use this function to temporarily run a
sql query on another database, you would have to manually switch back.
Users are strongly encouraged to use the
database.table syntax in their sql queries instead of
this function.

mysql_query().
