The DSQL error is coming from the database, IBO is merely delivering it. Have you tested your statements with an interactive tool like IB_SQL or isql?

What database and version are you using - did you change to a higher one, for example? If you moved forward from IB 5.x, expressions involving date literals now work differently...e.g. you example statement would be

delete from tablename
where recorddate < (cast ('today' as date) - 3)

But the DATE type has also changed - what was DATE in 5.x is now TIMESTAMP - although the DSQL error you are getting doesn't appear to be reporting a type mismatch...

More info please.
