274 Getting Started with IBM Data Studio for DB2 Figure 9.8 –Run the user-defined function A window opens that lets you specify whether you want to commit the changes to the database and capture database performance statistics. Accept the defaults and click OK. When you capture database performance statistics, the statistics appear in the SQL Results view. Note: When testing your UDF, you can create routine test configurations. Test configurations contain settings that are used when you run the UDF. The routine test configurations can help test routines and validate changes you make to a routine. You can create multiple test configurations that pass different input values to test different portions of a routine. When you run a routine with a test configuration, you can compare the result output and output parameter values with a predefined set of values. The results of the comparison appear in the SQL Results view. 9.5 View the output The SQL Results view shows the status of running your UDF. The Status column of this view indicates success or failure of the operation. The Operation column shows the command type or the actual command itself. The Status tab on the right shows detailed

This is illustrated in Figure 9.9. Figure 9.9 – View UDF results 9.6 Edit the procedure In Data Studio, a UDF can be viewed and edited in the routine editor. To open a UDF in the routine editor, double-click the UDF name or right-click and select Open as shown in Figure 9.10. Figure 9.10 – Open an existing UDF in the routine editor The routine editor provides syntax checking, and context sensitive semantic help that is similar to the one in SQL editor that was discussed in Chapter 5. In addition, the routine
