This usually indicates that your EXECUTE is executing at a different execution layer. Prime INFORMATION did this by default and had to use PERFORM to use the same runtime execution layer or overide with a $option statement. ________________________________________ From: u2-users-boun...@listserver.u2ug.org [u2-users-boun...@listserver.u2ug.org] On Behalf Of Dan McGrath [dmc...@imb.com.au] Sent: Monday, 12 October 2009 1:56 PM To: u2-users@listserver.u2ug.org Subject: [U2] EXECUTE 'CLEARSELECT'
Hi all, One of the programmers here has noticed this quirky behaviour in Unidata 7.1. First, we created a file called TEST and gave it 3 records, AA, AB and AC. Then we executed the following program: PROGRAM TEST CLEARSELECT EXECUTE 'SELECT TEST WITH @ID = "A]"' CRT "Records after SELECT ":SYSTEM(11) READNEXT KEY ELSE NULL EXECUTE "CLEARSELECT" CRT "Records after EXECUTE CLEARSELECT: ":SYSTEM(11) EXECUTE 'SELECT TEST WITH @ID = "A]"' CRT "Records after SELECT ":SYSTEM(11) READNEXT KEY ELSE NULL CLEARSELECT CRT "Records after CLEARSELECT: ":SYSTEM(11) EXECUTE 'SELECT TEST WITH @ID = "A]"' CRT "Records after SELECT ":SYSTEM(11) STOP and received the following results: 3 records selected to list 0. Records after SELECT 3 Records after EXECUTE CLEARSELECT: 2 3 records selected to list 0. Records after SELECT 2 Records after CLEARSELECT: 0 3 records selected to list 0. Records after SELECT 3 We would expect SYSTEM(11) to return 0 after the EXECUTE "CLEARSELECT" but it returns how many items were in the list prior to the CLEARSELECT. Also odd is that the select itself returns that it selected 3 records, but then SYSTEM(11) reports 2 and READNEXT will only extract 2 from the list. The work around is to use Unibasic CLEARSELECT which functions correctly as demonstrated above. When testing this using BASICTYPE "u" and "WHEN @ID LIKE" the issue did not present itself. I have tested both UNIX and Windows. Does this happen in 7.2?
