Z SQL Method Object: Query relational databases with SQL Description Z SQL Methods allows you to access data in SQL databases. Z SQL Methods define and call SQL statements on databases which are defined by database adapter objects. To create a new Z SQL Method you will need to setup a database adapter first. Every Z SQL Method is directly linked to a database connection through a database adapter. **Note:** You must associate a Z SQL method with a database adapter. If Zope cannot find a database adapter from your location, you will not be able to create a Z SQL Method.
