[SOLVED] Trouble with getting distinct value list with row counts
Hi,

Trying to do a distinct on a table field to receive the distinct values then add a row counter to each, (to be used for iteration). I've tried a few different routes to do this but the latest through the UI is here:

TABLE FILE TMP
SUM
COMPUTE ROWCNT/I9 = LAST ROWCNT + 1;
PRINT
DST.GUID
END

This gives me a distinct list of GUIDs but only the first row has a ROWCNT. Thoughts?

Thanks!

Sorting it by GUI will give you distinct values, so
TABLE FILE TMP
SUM COMPUTE ROWCNT/I9 = LAST ROWCNT + 1;
BY GUID
END

Or

TABLE FILE TMP
RANKED BY GUID
END

Follow up: I went the ranked route.

W.r.t. the 'BY' route though, I thought 'BY' is used for sorting, why would it result in a distinct in this case?

Thanks!

BY is for sorting and grouping. So in this case the most important thing is to group on GUID.

For the database group by or distinct is the same thing in terms of results.
