Re: How are null's stored?

I don't seem to have this problem; I use TEXT or VARCHAR willy-nilly, 
including in LIKE 'string%' and UPPER(field) queries, and the indexes work 
fine.

I suspect that either you're talking about TEXT to CHAR(x) comparisons, which 
are a different ball o' wax, or your query problem is something else.
