python mysql.connector.errors.InterfaceError: Use multi=True when executing multiple statements
阿新 • • 發佈:2018-12-23
一時疏乎,同一個 cursor.execute 下了 2個 sql command 就出錯了。
除了可以分成 2 次下 cursor.execute() 也可以在 cursor.execute 時增加 multi=True 引數。
合在一起下的 example:
Using a for
loop at cursor.execute
with multi=True
worked. I don’t know why we need to loop through.
for result in cursor.execute(SQL, multi=True):
pass
Without loop just cursor.execute(SQL, multi=True)
import mysql.connector
cnx = mysql.connector.connect(user='scott', database='test')
cursor = cnx.cursor()
SQL = '''
update my_table
set
LAY = 'P6682'
, BLK = 'P6682'
, ANI = 'P6682'
where
Shot = 'SH01';
update my_table
set
LAY = ' 1863'
, BLK = '1863'
, ANI = '1863'
where
Shot = 'SH02'
'''
for result in cursor.execute(SQL, multi=True):
pass
cnx.commit()
cur.close()
cnx.close()
cnx.disconnect()
