Hello. It will be very helpful if you can include the following data: Source OS: Source DB: Target OS: Target DB: A dump of the DB that you are trying to migrate. Besides that you can try with our latest WB version and let us know if the problem persist. Thanks.

Reopening this bug because I am getting the same error with version 6.3 Source OS: Centos 6 Source DB: MySQL Target OS: Centos 6 Target DB: MySQL I am trying to migrate from one database into another on the same machine. Source database is case insensitive and target is case sensitive collation. Please help

In db_mysql_re_grt.py, reverseEngineer() function under the following sections:
Line 335: if get_routines:
After the lines "sql = result.stringByName("Create Procedure")" and "sql = result.stringByName("Create Function")" there needs to be check for if sql is valid before updating the progress bar. I fixed mine by putting the grt. lines under a "if sql and sql is not None:".
The error will happen if the user doesn't have ALTER ROUTINE grant as mysql will return null for the "Create Procedure" or "Create Function" fields when asked for a SHOW CREATE PROCEDURE or SHOW CREATE FUNCTION.
I got this last week on workbench 6.3.7, OS X 10.11.6, and mysql 5.6.26-74.
A proper fix might ask for the user's grants and just skip the two sections if its not possible, but I didn't go so far as to parse the SHOW GRANTS syntax, as applying the correct context might be "fun".
