I take it you mean BLOB or VARCHAR, I've never heard of memo fields in Firebird?

I think SELECT * FROM MYTABLE WHERE MYMEMO CONTAINING 'FIND ME' is case 
insensitive. One, probably better, alternative would be to use a case 
insensitive collation, but I doubt collations can be used in blobs (it should 
work in a varchar). And you're right, it will be slow since no indexes can be 
used (hopefully, we're not talking about more than a few million rows in this 
table?)...

HTH,
