This gets a little trickier, but how about: 1) SELECT PEOPLE TO 1. 2) SELECT REGISTRATION WITH EID = '1' SAVING UNIQUE PID. 3) SELECT PEOPLE TO 2. 4) MERGE.LIST 1 DIFF 2 TO 3. 5) SAVE.LIST XXX FROM 3.
This does assume that steps 1 and 2 actually return at least 1 key. MERGE.LIST is an amazingly powerful command. It only works with the native UniData (UniVerse?) syntax as do the specific list #s, but it is easy enough to use the lower case verbs to force the individual commands to run in native mode.

SELECT REGISTRATION WITH EID = '1' SAVING UNIQUE PID NSELECT PEOPLE Or am I missing something?

I have file1 - "people" that has @ID of PID I have file2 - "registration" that has @ID of PID+EID+RID (EID = event id, RID = registration id) I want to select people who are not in the registration file with an EID of "1". With an SQL statement - I could join the two, then do the select or use a subquery (I'm on UV 10.0.2 - not sure if sub querys work) Just curious how this could be done with UV Native, and without involving a program. I first tried "SELECT REGISTRATION WITH EID = '1' SAVING UNIQUE PID" -> "NSELECT PEOPLE" But that returned 0 - since the NSELECT only works off the current select list, not the whole file Yes, I could create a temporary file, then select off that Yes, I could read each people record, then loop through registration to see if it doesn't exist. Both of the above require programming I guess I could create a subroutine that does the looping through registration, and put that into an I descriptor - looking for another option.
