Bulk Transfer Works
As many already know, I’ve been trying to get the MySQL Workbench migration feature working between Microsoft SQL Server 2012 and MySQL 5.5. There are a number of features added to the 5.2.43 point release, and one led me to believe that the Migration tool expects to find the data in a schema of its own, as opposed to the dbo schema. Having made that change in Microsoft SQL Server, it did appear to have a positive impact on the migration and when I corrected a character set mismatch it worked perfectly!
MySQL Workbench successfully migrated the schema and table but failed to migrate the data because of a character set mismatch. I updated Bug 66516 the log file from the character set mismatch before I retyped all 9 test rows to make sure they were in a latin1 character set.
I shortened the original log file because the actual log had over 2,000 blanks line :-(. That’s probably something that should be fixed in the code too.

Originally, I thought the failure was due to the extended ASCII characters in the Microsoft SQL Server table. It still failed when I took all of the extended characters out. However, Alfredo suggested it was a character set issue, which is obvious when I looked more closely at the log – '\x9Acak' is clearly an incorrect string. I retyped the INSERT statement for the nine rows and it worked perfectly. Naturally, I’ve updated open Bug 66516 with the log file.
