Hmmm.... AFAIK, there's no such animal as <dtml-comma>. But without much research on the matter, I'd say that this'd do it: UPDATE users SET <dtml-sqlgroup> <dtml-sqltest login type=nb optional> <dtml-if email>,<dtml-sqltest email type=nb optional></dtml-if> </dtml-sqlgroup> WHERE <dtml-sqltest userid type=int> Guy Davis wrote:

I now have all my insert and select queries working, but am having trouble with an UPDATE. For the query: UPDATE users SET <dtml-sqlgroup> <dtml-sqltest login type=nb optional> <dtml-sqltest email type=nb optional> </dtml-sqlgroup> WHERE <dtml-sqltest userid type=int>

This works perfectly except when both login and email are provided because the query becomes: UPDATE users SET login='a_login' email='an_email' WHERE id=1

Without the comma between the login and email, it doesn't work. I loved the <dtml-and> and <dtml-or> tags for SELECT statements. I tried a <dtml-comma> but no such luck. Does this exist or do I need to use separate UPDATE statements for each column, each wrapped in a <dtml-if>?
