Strongly do not recommend to use executeMany in pyodbc as well as ceodbc both slow and contains a lot of bugs.

Instead consider use execute and manually construct SQL query using simple string format.

transaction = "TRANSACTION BEGIN {0} COMMIT TRANSACTION

bulkRequest = ""
for i in range(0, 100)
    bulkRequest = bulkRequest + "INSERT INTO ...... {0} {1} {2}"

ceodbc.execute(transaction.format(bulkRequest))

Current implementation is very simple fast and reliable.
