Python中的MySQL语法错误

Question

I have 5 MySQL columns. I want to insert data into my columns with a for loop. But I always get an error.

SQL query:

for i in range(5):
    sql = "INSERT INTO fighters({},{}) VALUES(%s,%s) WHERE clan=%s".format("shot_" + str(i), "damage_" + str(i))
    cur.execute(sql, (shot, damage, clanname)
    conn.commit()

Error:

pymysql.err.ProgrammingError: (1064, u"You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'WHERE clan='blacks'' at line 1")

Answer 1

You need to update rather than insert:

sql = "UPDATE FIGHTERS SET shot_{0} = %s, damage_{1} = %s WHERE clan=%s".format("shot_" + str(i), "damage_" + str(i))
cur.execute(sql, (shot, damage, clanname,))

Hope that helps.
