Did you create an Index on column "spell" beforehand? (In that case, since you already gave the Collation in the Column-Def, you would not need to give the NoCase- Collation explicitely again in the Create Index-Statement). > QUESTION: > Is it possible to confirm that the column actually has been created > with NOCASE collation? Why not just test, what a simple Select gives as a result of e.g.: Select spell From Words Where spell = 'abc' Limit 1 In case column spell contains a "known word" as 'Abc' for example, you should get back a resulting row - if NoCase wouldn't have been recognized correctly, you shouldn't get back a string-result (a resulting row) from that query (in such a case-insensitivity-provocing Comparison-Attempt).
