Hi there
I'm a Firebird newbie (Oracle is my home), so please pardon me if this is a silly question. I'm
trying to get something like this

SELECT MAX(LENGTH(A_VARCHAR_FIELD)) FROM MY_TABLE

I've tried it with strlen but I alway get this error message:

GDS Exception. 335544569. Dynamic SQL Error
SQL error code = -804
Function unknown
STRLEN

Any hints?

Regards
Louis
