怎么做福彩网站,做个卖东西的网站,wordpress占用多大内存,wordpress 文章副标题python在操作数据库执行sql的时候我们经常会遇到传参问题#xff0c;以下是我总结的几种方法#xff1a;
1、格式化字符串
city beijing
cur.execute(“SELECT * FROM %s WHERE city %s”, city)
2、使用字典传递

1、格式化字符串
city beijing
cur.execute(“SELECT * FROM %s WHERE city %s”, city)
2、使用字典传递
sql “INSERT INTO user VALUES(%(username)s, %(password)s, %(email)s)”
value {“username”:zhangsan,“password”:123456,“email”:123456ouvps.com}
cur.execute(sql, value)
3、传递参数参数名称利用‘三引号’实现复杂SQL的换行然后对参数进行拼接如下样例中的time根据自己的情况而定
def sql_func(time):
time time
fail_sql
SELECT substr(s_start_time,1,10) 日期,count(*) 失败数量
FROM T_SG_WS_EXE_LOG L
WHERE 1 1
AND (S_WS_METHOD NotifyOrderStatus OR (S_WS_METHOD placeOrder AND S_IS_OK false))
and s_request_str not like %deployStatus:2120% and s_request_str not like %deployStatus:0%
and substr(s_start_time,1,10) time group by substr(s_start_time,1,10)# 使用cursor进行各种操作
ycr.execute(fail_sql)
result y.fetchall()
return result
