I can't think of a simple answer. I think you would need some kind of programmatic solution like a client side program thatwould create a temporary table with a serial field in it, populate it with data based on your query, then return thedata. The temp table would go away with the connection. A function could create the table but you would still have toquery the resulting table since functions can't return query results directly yet.

Can anyone tell me how to get a sequential row count field in the output of a query? Say I want to query for all users in a table sorted by lastname and firstname. I would like to include a column in my query called "rownum" which would uniquely identify the row in the order of the queryresults. Like this: rownum =1 lastname=jones, firstname=john rownum=2 lastname=smith, firstname=john etc. I assume rownum should be some kind of function of expresion but I don't know what. Something like: Select ???? as rownum, lastname,firstname from users where xxx =xxx order by lastname, firsname. ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to majordomo@postgresql.org so that your message can get through to the mailing list cleanly
