Hi..

Is it possible to use Join in UNload utility while extracting data from DB2 tables as below? KEY1 being common in both tables. This syntax fails saying select is invalid. Can u suggest any options if there is?
Code:

//DSNUPROC.SYSIN DD   *                                 
 UNLOAD DATA                                             
 FROM TABLE table1                           
  WHEN ( KEY1 IN (SELECT KEY1 FROM TABLE2
                            WHERE KEY2 = 'XYZ'));

vijay_bc,

create a view with the desired unload condition and do the unload using the view.

You should use the keyword WHERE instead of WHEN.

vijay_bc,

Use DSNTIUAL utility to unload the tables instead of the DB2 Unload utility. You can join up to 256 tables

CZerfas,

The syntax used by oP is correct for DB2 unload utility which is explained here
