问题描述
我有这样的code:
string insertSql = "INSERT INTO aspnet_GameProfiles(UserId,GameId) VALUES(@UserId, @GameId)"; using (SqlConnection myConnection = new SqlConnection(myConnectionString)) { myConnection.Open(); SqlCommand myCommand = new SqlCommand(insertSql, myConnection); myCommand.Parameters.AddWithValue("@UserId", newUserId); myCommand.Parameters.AddWithValue("@GameId", newGameId); myCommand.ExecuteNonQuery(); myConnection.Close(); }当我插入这个表,我有一个auto_increment int主键名为 GamesProfileId 专栏中,我怎么能得到最后插入一个接着这个,所以我可以使用该ID插入到另一个表?
When I insert into this table, I have an auto_increment int primary key column called GamesProfileId, how can i get the last inserted one after this so I can use that id to insert into another table?
推荐答案对于SQL Server 2005 +,如果没有插入触发器,然后更改插入语句(全部一行拆分为清楚起见,在这里)这个
For SQL Server 2005+, if there is no insert trigger, then change the insert statement (all one line, split for clarity here) to this
INSERT INTO aspnet_GameProfiles(UserId,GameId) OUTPUT INSERTED.ID VALUES(@UserId, @GameId)有关的SQL Server 2000,或者,如果有一个刀片触发
For SQL Server 2000, or if there is an insert trigger:
INSERT INTO aspnet_GameProfiles(UserId,GameId) VALUES(@UserId, @GameId); SELECT SCOPE_IDENTITY()然后
Int32 newId = (Int32) myCommand.ExecuteScalar();更多推荐
