mysql_db_query
mysql_db_query selects a database, and executes a query on it.
Parameters
- database
-
The name of the database that will be selected.
- query
-
The MySQL query.
Data inside the query should be properly escaped.
- link_identifier
The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect is assumed. If no such link is found, it will try to create one as if mysql_connect had been called with no arguments. If no connection is found or established, an E_WARNING level error is generated.
Return Values
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.
Notes
Note:
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 or mysql_select_db instead of this function.
