我正在使用从 MySQL 站点下载的 mysql connector.Python 1.0.9。
DROP TABLE IF EXISTS my_table;
CREATE TABLE my_table
(id INT NOT NULL AUTO_INCREMENT UNIQUE,
Shot VARCHAR(4),
sec varchar(5),
lay VARCHAR(15) NOT NULL,
lay_status VARCHAR(15) NOT NULL,
blk VARCHAR(10) NOT NULL,
blk_status VARCHAR(15) NOT NULL,
pri VARCHAR(10) NOT NULL,
pri_status VARCHAR(15) NOT NULL,
ani VARCHAR(10) NOT NULL,
ani_status VARCHAR(15) NOT NULL,
status VARCHAR(5)
);
INSERT INTO my_table VALUES
(1,'SH01','3','1863','yes','1863','yes','P4645','yes','P4557','yes','Over'),
(2,'SH02','2.5','1863','yes','P4645','no','P4557','yes','1863','no','Over'),
(3,'SH03','0.5','P4645','yes','P4557','yes','1863','yes','1863','yes','WIP'),
(4,'SH04','1.25','1863','no','P4645','no','P4557','yes','1863','yes','RTK'),
(5,'SH05','1','1863','yes','1863','yes','P4645','yes','P4557','yes','WIP'),
(6,'SH06','6','P4557','yes','P4645','yes','P4645','yes','P4557','yes','WIP');
我能够执行如下的单个 SQL 语句。
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';
'''
cursor.execute(SQL)
一切都很好,数据库得到正确更新。
现在,当我尝试使用以下多个语句更新数据库时
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'
'''
cursor.execute(SQL)
cnx.commit()
cur.close()
cnx.close()
cnx.disconnect()
我得到以下引用错误
Traceback (most recent call last):
File "Test_Module.py", line 24, in
File "C:\Python26\Lib\site-packages\mysql\connector\cursor.py", line 396, in execute
"Use multi=True when executing multiple statements")
InterfaceError: Use multi=True when executing multiple statements
我更新我的命令如下
cursor.execute(SQL,multi = True)
cnx.commit()
cur.close()
cnx.close()
cnx.disconnect()
现在我没有收到任何错误/回溯。但是数据库没有更新。
谁能告诉我我在哪里做错了。
