如何使用python将变量插入MySQL表

Question

I have looked all over stack overflow and none of the answers works. This is the code below:

var = ""


sql = "INSERT INTO yyc_central (NO) VALUES %s"

mycursor.execute(sql, var)

I am using mysql.connector to connect to my database. I am also getting an error that says:

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 '?' at line 1

Don't mind "line 1" I really need help please and thank you.

Answer 1

python is somewhat peculiar with only 1 parameter, so

var = ""


sql = "INSERT INTO yyc_central (NO) VALUES (%s)"

mycursor.execute(sql, (var,))
