Hi David and thanks for your report. I have two things for you to try before I rule on this:
 1) Please use test case (modify if necessary) from Bug#18755 and retry. Inform me of result.
 2) Try with latest MyODBC 3.51 as it is GA while 5.0.11 is still beta.

Thanks Tonci Grgin,

it's OK with the latest MyODBC 3.51.

I don't use test case from Bug#18755 cause i have no UNSIGNED BIGINT columns.

Thank's a lot and good way.

David, I just feel code in Bug#18755 is good, generally, it doesn't have to be BIGINT you can test with it...

Glad things work now!

As for v5, verified as described.

This happens to me too. I am trying to migrate data from mySQL into SQL Server 2005 using SSIS. I connect using ODBC 5 driver and it crashes when I then attempt to read data. Version 3.51 driver works ok in SSIS, however doesn't work with MSaccess or Microsoft Query/Excel etc.

I get thie error too.  I am creating a report in MS Visual studio 2005 that uses the .Net connector to connect to a mysql database.  When creating the connection in the report designer I can execute a simple query such as select * from tblcustomers.  But, when I go to the next step in the report designer, I rcv the error.

A mi me ha ocurrido al intentar crea un universo en Business Objects e intentar leer las tablas del datawarehouse que está en MySql.
