从MySQL返回最后插入的ID [英] Returning last inserted id from MySql
问题描述
我有一点麻烦用下面的查询:
I'm having a bit of trouble with the following query:
START TRANSACTION;
SET @LASTID = 0;
INSERT INTO `Accounts` (`Col1`,`col2`,`col3`,`col4`)
VALUES (@param1,@param2,@param3,@param4);
SET @LASTID = last_insert_id(); -- This is what I need
INSERT INTO `Users` (`usr1`,`usr2`,`usr3`,`usr4`)
VALUES (@usr1,@usr2,@usr3,@usr4);
SELECT @LASTID;
COMMIT;
基本上,我需要从账目表中返回最后插入的ID,但是运行SELECT @LASTID时,则MySQL返回一个blob,而不是一个单一的值,这我无法在C#asp.net访问
Basically, I need to return the last inserted ID from the accounts table, however when running SELECT @LASTID, MySql returns a blob rather than a single value, which I'm having trouble accessing in C# asp.net
有没有简单的方法来获得这个值作为一个int / VARCHAR?从斑点在code我觉得转换是矫枉过正了,我想,解除离开到MySQL服务器。
Is there any simple way to get this value as an int / varchar? Converting from blobs in code i feel is overkill, and I'd like to leave that lifting to the Mysql server.
先谢谢了。
推荐答案
使用
SELECT LAST_INSERT_ID();
的http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_last-insert-id
