Ricardo,

how does the declaration of the user-defined function look like?
In which directory have you placed the UDF-Library "BlobCompare.dll"?

Out of the replication help file, the declaration looks like.

/* Returns 1 if two blobs are equal, 0 if not */
DECLARE EXTERNAL FUNCTION FN_BLOBS_EQUAL
BLOB, BLOB
RETURNS INTEGER BY VALUE
ENTRY_POINT 'fn_blobs_equal'
MODULE_NAME 'BlobCompare';
