Subject case-insensitive searching
Date Tue, 10 Jun 2008 13:51:59 GMT
Hi Guys,

I was wondering what is being done for case-insensitive comparisons. Also wanted to propose
an implementation option, which would be to allow indexes to be created on UPPER or LOWER.
As long as I had an index on UPPER or LOWER, I could do this efficiently:

WHERE UPPER(T1.lastname) = UPPER(T2.lastname)

Is that a totally crazy suggestion, to allow indexes to be created on UPPER and LOWER? Maybe
this is easy to implement.
