Thanks for the reply Kris.
Before posting to the forum I tested with different name of "id" column such as "primaryid". The name "id" is not a problem as I have already generated the DDL for the tables of WSHT task and all the tables got created fine with "id" as the primary key column with 'bigint' as the column type. So just to test it again I changed the 'id' column name to 'primaryid' - the error is same Error: Incorrect column specifier for column 'primaryid' SQLState: 42000 ErrorCode: 1063 When i converted the varchar to bigint for the 'id' column - tables got created fine. Do let me know what do you think and how should I approach this issue?

Because to me it seems that MySQL is not accepting the name "id" as a valid column name? I guess changing the mapping so that it uses a different column name could fix the issue?
