The following figure shows the SQL Query Control component in Zend Core for IBM that can be used to enter DB2 UDB commands. It is similar to entering commands in the DB2 UDB Command Line Processor or the DB2 UDB Command Center:
The SQL Query Control window in the IDE also keeps a history of past SQL commands so that these can be easily recalled for future processing, which allows you to quickly change the server, database, and default schema where you want to execute your SQL statement, as shown below:
You can access the SQL Query Control feature such that it defaults to the correct server, database, and schema: simply right-click the object that you want to run the query against and select Query, as shown below:
Wrapping it all up
In this article, I gave you a brief overview of some of the tooling support in the Zend Core for IBM product that makes developing PHP applications for DB2 UDB (or Apache Derby/IBM Cloudscape) databases easier than ever.
Stay tuned for an article on Java and DB2 UDB programming.
