No worries at all about pointing out a stupid error on my part. Wouldn't be the least bit shocked if that isn't the underlying problem, and if it is I'll throw a party celebrating my own stupidity as long as it fixes the problem :).

The reason sys_id is being quoted is that the actual column name is (lower case) sys_id.

This is an old mySQL app that got ported to Oracle and the column names are all lower cased there since thats "more or less" the norm in mySQL land.

Hence when it came to oracle, the column names were, unfortunately still lower cased, and hence the necessity of quoting all references to them, which makes working with them on the CLI rather obnoxious.
