varchar to text
Hello.
There are some columns in my tables that I should change from varchar to text, in order to have enough space for long textual commentaries.
Before I do that, I would like to know is there any restriction regarding text type in comparison to varchar type?
Especially concerning triggers and rules ?
Namely, I have triggers that perform audit trail of all my tables, so I'm concerned whether it will work for text type fields ?
One additional question is regarding my MS Access front-end. Would it be a problem for Access ?
Thanks in advance,
Zlatko

The varchar type is text plus restrictions. So no, switching to text
lets you do more, not less...

The ODBC driver has something like "map text to memo". Make sure that's
off, otherwise access won't let you do comparisons on it.
Hope this helps,
