Python将变量分配给MYSQL查询的正确方法？

Question

What are different ways to reference a Python variable into MySQL statement?

I know you can reference like this:

var = "String"

cursor.execute("select * from table where column1 = %s") % (var)

I saw somebody mention to use ? . What are other ways to do it?

Answer 1

You can do this by passing parameters:

cursor = connection.cursor(prepared=True)
sql_insert_query = """ INSERT INTO Employee
                       (id, Name, Joining_date, salary) VALUES (%s,%s,%s,%s)"""

insert_tuple_1 = (1, "Json", "2019-03-23", 9000)
cursor.execute(sql_insert_query, insert_tuple_1)
connection.commit()
