As I stated in my first post, my circumstance was in another dialect of
SQL. I just hope that it can provide a direction for you.

Someone else would have a better idea of what UDF's are available to do
this in Firebird. Alternatively, there might be an IsNumeric UDF in
one of the standard UDF libraries.

What would it take to write a "isNumeric" UDF ic C/C++?
