Snowflake Connector for Python 中的事务和回滚

Question

I am using the Snowflake Connector for Python as follows:

ctx = snowflake.connector.connect(user=username, password=password, account=account, warehouse=warehouse)
cs = ctx.cursor()
try:
 cs.execute(u"begin")
 cs.execute("TRUNCATE table1")
 cs.execute("TRUNCATE table2")
 cs.execute("TRUNCATE table3")
 ctx.commit()
except snowflake.connector.errors.ProgrammingError as e:
  ctx.rollback()
  print("ERROR" + e.msg)
finally:
  cs.close()
  ctx.close()

Essentially I want to rollback if there are any issues with any of the SQLs (TRUNCATES). But this code doesn't seem to rollback.

Any ideas on what could be causing this?

From the docs , you will have to set autocommit to False in order for Rollback to work, however, i am having trouble getting it to work even with it set. Please post your findings.

ctx = snowflake.connector.connect(autocommit=False,user=username, password=password, account=account, warehouse=warehouse)
