pymysql

Question

这是我的代码：

def lookfor(var1, var2):

try:
    with connection().cursor() as cursor:
        sql = """SELECT * FROM servers WHERE %s = %s"""

        cursor.execute(sql, (var1, var2))
        result = cursor.fetchall()

        for x in result:
            print(x)
finally:
    connection().close()

寻找("priority", "Important")

我得到 0 个结果并且没有错误...:(

请帮忙，一定有办法做到这一点。

Answer 1

您可以使用字符串插值：

with connection().cursor() as cursor:
        sql = "SELECT * FROM servers WHERE " + str(var1) + " = " + str(var2)

        cursor.execute(sql)
        result = cursor.fetchall()

pymysql - 是否可以将变量用作 "Where" 参数？

pymysql - is it possible to use a variable as a "Where" parameter?
