Question

I'm trying to insert some variables into my database, but I'm getting this error, I don't know what I'm doing wrong, could you help me? Thanks in advance

import mysql.connector as co
import time as tm
dbConnect = {
    'host':'mx102.hostgator.mx',
    'port':'3306',
    'user':'meandmic_root',
    'password':'abcde',
    'database':'meandmic_analizador'
}

felicidad = 0
enojo = 0
sorpresa = 0
tristeza = 0
neutral = 0
dt = tm.strftime("%d/%m/%y")
conexion = co.connect(**dbConnect)
cursor = conexion.cursor()
sqlInsertar = "insert into registros(CFELICIDAD,CENOJO,CSORPRESA,CTRISTEZA,CNEUTRAL,FECHA)values(%s,%s,%s,%s,%s,%s)"
cursor.execute(sqlInsertar,[felicidad,enojo,sorpresa,tristeza,neutral,dt])
conexion.commit()

Answer 1

尝试将您的列表更改为元组：

cursor.execute(sqlInsertar,(felicidad,enojo,sorpresa,tristeza,neutral,dt))

Answer 2

As Mikhail Ilin mentioned, the cursor.execute method expects a tuple as the second parameter.

The official documentation 6.9.5.4 MySQLCursor.execute() Method has an example query that is very similar to yours.

insert_stmt = (
   "INSERT INTO employees (emp_no, first_name, last_name, hire_date) "
   "VALUES (%s, %s, %s, %s)"
)
data = (2, 'Jane', 'Doe', datetime.date(2012, 3, 23))
cursor.execute(insert_stmt, data)

In this example, data is a tuple , not a list .
