When I try to declare a function in the ib_udf

DECLARE EXTERNAL FUNCTION bin_xor
INTEGER, INTEGER
RETURNS INTEGER BY VALUE
ENTRY_POINT "IB_UDF_bin_xor" MODULE_NAME "ib_udf";

I get the error
"-Metadata update statement is not allowed by the current database SQL dialect 3"

What am I doing wrong here??
