Import mysql.connectorimport sysuser = 'root'pwd =' root'host = '20.0.2.50'db='mysql'create_tab_sql = "CREATE TABLE IF NOT EXISTS TAB_TEST (\ TAB_NAME VARCHAR (20),\ CITY_NAME VARCHAR (20))\ CHARACTER SET utf8" conn = mysql.connector.connect (user=user,password=pwd,host=host) Database=db) cursor = conn.cursor () try: cursor.execute (create_tab_sql) except mysql.connector.Error as err: print ("create table 'tab_test' failed.") Print ("Error: {}" .format (err.msg)) sys.exit ()
