Hi there,
I try the following statement:
CALL selectVertexProperties(1, @error2)
when I execute this directly in the test window of the database
connection, it works fine.
when i execute the same line in the test window of a ZSQL Method
then I get an error:
Error, Products.mxODBCZopeDA.ZopeDA.ReplayTransaction: OperationalError
on : ('HYT00', 2014, [unixODBC][MySQL][ODBC 3.51
Driver][mysqld-5.0.26]Commands out of sync; you can't run this command
now, 6113) SQL used:
CALL selectVertexProperties(1, @error2)
when I call this method from plain python, it works fine also.
Any pointers what could be the reason would be greatly appreciated.
Robert,
Can you give an example of how you call this in plain python? It may be
that in using plain python you are starting a new transaction, and there
are previous sql commands which are causing problems. Perhaps some more
details of the sql statements issued would be helpful also.

Robert,
Looks very much like an issue due to transactions. Are you using auto-commit
on either the MySQLdb connection or the zope database adapter? Perhaps
you could test the issue by placing get_transaction().commit() before
the start of your zope database code, and get_transaction().commit() at
the end. Please don't do this in production code, this is just to
isolate the issue.
Regards,
Kevin
