You can sort the data in this result grid as well. (Note the circled toggle on the DIV column heading; the up arrow here indicates that this column was sorted in ascending order)

If the table whose data you want to view has a lot of rows, you can customize the IDE to retrieve rows in piecemeal fashion:

Another important feature for developers in Zend Core for IBM is the integrated debugger. Like any debugger, it allows application developers to step through their code and change variables on the fly. An example is shown below:

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:
