Hello FireBird Support!

I need execute this command

"Select MyColumn from MyTable Where MyUDF(MyColumn) Starting
MyUDF(@MyParam)";

or

"Select MyColumn from MyTable Where MyColumn Starting
MyUDF(@MyParam)";


but this command raise exception "Data type unknown".
MyUDF is udf with replace national chars to basic ASCII and convert
ToUpper();
