Hi, all.

I need an UDF which returns me a substring and the
string length of a VARCHAR.

The SUBSTR function in ib_udf.dl doesn't support
VARCHARs longer than 80 chars (though it is suposed
in the documentation).

What I wan't to do is extracting PKs from a string
which is delivered by my app.

Any ideas or a link to a UDF which has the described
functionality?

Regards

Jürgen
