Database migration from Sybase to MySQL: “ error calling Python module function DbSQLAnywhereRE.reverseEngineer”

Question

I'm trying to migrate a database from Sybase to MySQL with the MySQL Workbench migration tool.

I have no problem connecting the datasource and the target database, but when it starts migrating I get the following issue from the log message.

Starting...
Connect to source DBMS...
- Connecting...
Connect to source DBMS done
Reverse engineer selected schemas....

How do I solve this issue?

Answer 1

That's because of SQL to get table names. Look at db_sqlanywhere_re_grt.py:142, there is:

SELECT st.table_name
FROM SYSTAB st LEFT JOIN SYSUSER su ON st.creator=su.user_id
WHERE su.user_name = '%s' AND st.table_type = 1

This is valid sql for sql anywhere version < 10, and I guess you have newest version. So you can edit and update that file with compatible SQL. Keep in mind there is much more SQL's that also need to be updated in that file. In meantime, please fill the bug report at bugs.mysql.com .
