python - MysqlPython : Not all parameters were used in MySQL statement

Question

所以我试图将数据作为变量输入到我的表中，但我似乎不断收到错误 mysql.connector.errors.ProgrammingError: Not all parameters were used in the SQL statements，我使用了 %s 而不是行名称，但我似乎不断收到相同的错误。我怀疑这是我的语法，但我似乎无法弄清楚这是我第一次同时使用 python 和 MySQL

import mysql.connector


Sensor_ID = "test"

Location = "room"

Sensor_IP = "192.168.1.1"

Sensor_1 = "10"

Sensor_1_Unit = "*C"

Sensor_2 =""

Sensor_2_Unit = ""

Sensor_3 = ""

Sensor_3_Unit = ""

conn = mysql.connector.connect(user='******', password='********',    host='******', database='*****') #blanked my user n pass
mycursor = conn.cursor()
mycursor.execute('SHOW TABLES')
print(mycursor.fetchall())
print ""

mycursor.execute("SHOW VARIABLES LIKE '%version%'")
print "Version:",(mycursor.fetchall())
#works up to here

mycursor.execute("INSERT INTO iot_sensors VALUES (ID, Sensor_ID, Location, Sensor_IP, Sensor_1, Sensor_1_Unit, Sensor_2,Sensor_2_Unit, Sensor_3,   Sensor_3_Unit)",(Sensor_ID,Location,Sensor_IP,Sensor_1,Sensor_1_Unit,Sensor_2,Sensor_2_Unit,Sens or_3,Sensor_3_Unit))
conn.commit()

  #    Sensor_ID,Location,Sensor_IP,Sensor_1,Sensor_1_Unit,Sensor_2,Sensor_2_Unit,Sensor_3,Sensor_3_Unit

创建表 IoT_Sensors(

ID INT NOT NULL AUTO_INCRMENT，

Sensor_ID VARCHAR (15) NOT NULL，

位置 VARCHAR (20) NOT NULL，

Sensor_IP VARCHAR (15) NOT NULL，

Sensor_1 VARCHAR (15) NOT NULL，

Sensor_1_Unit VARCHAR (15) NOT NULL，

Sensor_2 VARCHAR (15)，

Sensor_2_Unit VARCHAR (15)，

Sensor_3 VARCHAR (15)，

Sensor_3_Unit VARCHAR (15)，

Time_Stamp 时间戳不为空，

主键(ID))；

您需要将 %s 放入 SQL 语句中。

mycursor.execute("INSERT INTO iot_sensors VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)",(Sensor_ID,Location,Sensor_IP,Sensor_1,Sensor_1_Unit,Sensor_2,Sensor_2_Unit,Sens or_3,Sensor_3_Unit))

请参阅 docs 中的示例.
