Christy,
this is rather odd. Even if the argument is not a string (and by #1 it
means the second argument), the first thing strConcat tries to do is to
convert it to a string. The only thing that I can think of that might
cause this to fail is that the type is some big integer that it cannot
handle, or null. Ordinary integers should be converted.
Can we please see the DDL for the source table?
Is objectid ever null?
select count(1) from yourtablename where objectid is null;
Kind regards,
Ben.
