使用Python插入MySQL表

Question

I am trying to insert basic data into my MySQL table without any success yet I'm using basic tutorials as demos.

mysql.connector.errors.ProgrammingError: 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s)' at line 1

My MySQL

CREATE TABLE awesome (
id int NOT NULL AUTO_INCREMENT,
test varchar(50),
PRIMARY KEY (id)
);

My Python code

import mysql.connector

mydb = mysql.connector.connect(
host="localhost",
user="root",
passwd="pass",
database="db"
)

mycursor = mydb.cursor()

sql = "INSERT INTO awesome (test) VALUES (%s)"
val = ("Highway 21")
mycursor.execute(sql, val)

mydb.commit()

print(mycursor.rowcount, "record inserted.")

Answer 1

Yes the problem arises when there is only 1 argument in val tuple. Use

val=("Highway 21",)

Note the comma at the end.
