Thanks Ryan. I guess I'm used to MS Access (can I mention those words in this mailing list?) which recognised the 'table name.field name' convention on all columns regardless. It made things 'lazy' I guess. If a table has 20 fields, then it can be a pain listing out every field required. A necessary evil, and 'the right thing', but still a pain...
