Q: 

Are UNIQUE indices case sensitive in MySQL?

Are indices (indexes) defined as UNIQUE case sensitive in MySQL?

+6  A: 

It depends on the collation of the field - if it's ci (case insensitive) or cs (case sensitive). The unique index would apply accordingly.

There's nothing special about UNIQUE indexes - they follow the same case options as other indexes.
