The problem:
Read records in file, update file field to identify type of sales. Then read the file again summarized quantity of item, color, sales type and write XML records to an IFS file.
Should I update the sales type in the same program? Say, one SQL subroutine to update and then another SQL subroutine to sum and write the same file? Or should I just have two separate programs?
After taking a break it took me five minutes to find the last piece of the puzzle bmyers.net/faq.
This program reads records, but will not allow updates or deletes. To make the program update-capable, a few simple changes are necessary.
First, the cursor declaration must remove the "For Fetch Only" restriction. To be able to update all fields in the record, use the following example:
Exec Sql Declare Mycursor Cursor For Select * From Mylib/Myfile;
Or, you may restrict the updates to specific field(s):
Exec Sql Declare Mycursor Cursor For Select * From Mylib/Myfile For Update of Myfield;
When your program is ready to update or delete a record, you will use a special syntax of the SQL Update or Delete statement to associate it with the currently fetched record:
Exec Sql Update Myfile Set Myfield = Newvalue Where Current of Mycursor;
Or:
Exec Sql Delete From Myfile Where Current of Mycursor;
