Well, here we are 7 months later, and I am finally back around to working on this Sql Sever conversion again. I have done a small test with your suggestion, and it seems like it is going to work out pretty well.

Thanks!

>>>text to lcInsert noshow
>>>declare @LocalTable (field1 varchar(10), field2 int)
>>>endtext

>>>select local cursor
>>>scan
>>>
>>> using textmerge create insert statements for the local cursor
>>>endscan

>For such tiny local cursors used as join filters you can locally pipe their PKs into a
server.pk IN (client.pk1, client.pk2... client.pk_max)
value_set clause to be used on the server in the where-clause.
