Can you get the lenght of the statment at the front end and see if it is longer that the dreaded 255?

If so chop it into parts , and them together and it will run! Having done this you look for a catch phrase that will be in the middle of the command. I chose "WHERE" myself.

Search the string for your word and get it's numeric location. No substring it to that point as str1. Substring the remainder to st2

sqlStr =str1 + str2

CYA here! use brackets instead of quotes because a quote can be used in the example area of the "where" : CCity = 'NYC'

now you can pass sqlstr to where ever you need it.
