The optdiag utility failed on my test table. I'm getting always this message:

Server Message: SYBASE_TEST - Msg 245, Level 16, State 1:
Domain error during explicit conversion of VARBINARY value '' to a NUMERIC field.
CSLIB Message: - L0/O0/S0/N25/1/0:
cs_convert: cslib user api layer: common library error: The datatype value is outside the domain of legal values for the datatype.
cs_convert() returned CS_FAIL.
Optdiag failed. Check for error messages above.

let me know what is wrong my table ?

Thanks in advance.
