2185320 - Alter table to add identity column sets wrong attributes in syscolumns causing errors during bulk load - SAP ASE and JDBC/jConnect

Symptom

  • Using "ALTER TABLE ADD column_name IDENTITY" command sets wrong attributes in the syscolumns system table
     
  • The following syscolumns fields are incorrect:
    • datatype = 108 (numericn), should be 63
    • offset = -11 (negative) and should be positive since the identity is fixed length
    • maxlen is off by one extra byte
       
  • When using ENABLE_BULK_LOAD in jConnect these errors can occur:
    • Server has encountered badly formatted rows from bulk copy. Could not locate the row position reserved for the insertion of the identity value.
    • Attempt to insert NULL value into column some_id, table some_table; column does not allow nulls.
