如何使用truncate在mysqldb中进行事务

Question

I am trying to truncate a table and then do some inserts and then commit it all at the end. However doing the following clears the table immediately:

>>> t.cursor.execute('START TRANSACTION;')
0L
>>> t.cursor.execute('TRUNCATE _tx;')
0L
# table is now cleared from truncate

How would I delay the 'truncate' until after I commit the transaction?

Answer 1

You can't use TRUNCATE within a transaction as it automatically commits. Better to do something like this:

>>> t.cursor.execute('DELETE FROM _tx;')
