How compare a DB filed BLOB type text using TCriteria Like/ILike ?

Hi, I tried TSQLFunctions but is not works, I need convert the TBlob field of entity as TBlob.AsString and compare with %stringValue% using like/ilike. TUtils.ValueToVariant make conversion of TBlob as bytes and I need that cast will be AsString.

Any suggestion will be very appreciated.

Thanks.
