How to get last inserted id?

Question

I have this 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();

}

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?

Answer 1

In SQL Server 2005+:  If there is no insert trigger available, then try changing the insert statement (all in one line) to this

INSERT INTO aspnet_GameProfiles(UserId,GameId)

OUTPUT INSERTED.ID

VALUES(@UserId, @GameId)

In SQL Server 2000, if there is an insert trigger like this:

INSERT INTO aspnet_GameProfiles(UserId,GameId) 

VALUES(@UserId, @GameId);

SELECT SCOPE_IDENTITY()

Then use this:

 Int32 newId = (Int32) myCommand.ExecuteScalar();
