从SQL插入查询中获取新记录主键ID以将相同值插入另一个表中？

Question

我有以下C#

protected void add_button_Click(object sender, EventArgs e)
{
    string teamname = team_name_tb.Text;
    string teamstatus = "Not Started";
    string teamnotes = team_notes_tb.Text;
    string sprintid = sprint_select.SelectedValue;

    string ConnectionString = WebConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
    SqlConnection myConnection = new SqlConnection(ConnectionString);

    myConnection.Open();

            String query = "INSERT INTO teams (team_name, status, notes) 
                            VALUES (@team_name, @status, @notes); 
                            INSERT INTO sprints_vs_teams (sprint_id, team_id)                    
                            VALUES (@sprint_id, @team_id)";

            SqlCommand myCommand = new SqlCommand(query, myConnection);
            myCommand.Parameters.AddWithValue("@team_name", teamname);
            myCommand.Parameters.AddWithValue("@status", teamstatus);
            myCommand.Parameters.AddWithValue("@notes", teamnotes);
            myCommand.Parameters.AddWithValue("@sprint_id", sprintid);
            myCommand.Parameters.AddWithValue("@team_id", ????);

            myCommand.ExecuteNonQuery();
            myConnection.Close();
}

在teams表中主键是team_id我希望能够拉出它的值并将其插入到team_id我查找表中的字段中sprints_vs_teams.有没有这样做的方法,如果可以的话,你可以提供一些指导,请注意我对C#很新.任何帮助将不胜感激.

修改后的代码

protected void add_button_Click(object sender, EventArgs e)
{
    String user = Session["user_id"].ToString();
    string teamname = team_name_tb.Text;
    string teamstatus = "Not Started";
    string teamnotes = team_notes_tb.Text;
    string sprintid = sprint_select.SelectedValue;

string ConnectionString = WebConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
SqlConnection myConnection = new SqlConnection(ConnectionString);

myConnection.Open();

String query = "Declare @team_identity int INSERT INTO teams (team_name, status, notes) VALUES (@team_name, @status, @notes); set @team_identity = scope_identity() INSERT INTO sprints_vs_teams (sprint_id, team_id) VALUES (@sprint_id, @team_identity)";

       SqlCommand myCommand = new SqlCommand(query, myConnection);
        myCommand.Parameters.AddWithValue("@team_name", teamname);
        myCommand.Parameters.AddWithValue("@status", teamstatus);
        myCommand.Parameters.AddWithValue("@notes", teamnotes);
        myCommand.Parameters.AddWithValue("@sprint_id", sprintid);

        myCommand.ExecuteNonQuery();
        myConnection.Close();
}

我用@Sick的答案修改了我的代码,但它似乎没有用.如果有人可以就我可能出错的地方提出建议,我们将不胜感激.

Answer 1

使用SCOPE_IDENTITY

Declare @team_identity int

INSERT INTO teams (team_name, status, notes) 
                            VALUES (@team_name, @status, @notes);

set @team_identity = scope_identity()

INSERT INTO sprints_vs_teams (sprint_id, team_id)                    
                            VALUES (@sprint_id, @team_identity)"
