how do i get the returned id from the store proceedure in asp c#?

my store proceedure gets the id:

CREATE PROCEDURE createpost(
@.userID integer,
@.categoryID integer,
@.title varchar(100),
@.newsdate datetime,
@.story varchar(250),
@.wordcount int
)
as
DECLARE @.newNewsID integer

Insert Into TB_News(UserID, CategoryID, title, newsdate, StoryText, wordcount)
Values (@.userID, @.categoryID, @.title, @.newsdate, @.story, @.wordcount)

SELECT @.newNewsID = @.@.IDENTITY

then im calling it in the asp:

con = new SqlConnection ("server=declt; uid=c1400046; pwd=c1400046; database=c1400046");
con.Open();

cmdselect = new SqlCommand("createpost", con);
cmdselect.CommandType = CommandType.StoredProcedure;


cmdselect.Parameters.Add("@.userID", userID);
cmdselect.Parameters.Add("@.categoryID", categoryID );
cmdselect.Parameters.Add("@.title", title.Text );
cmdselect.Parameters.Add("@.newsdate", newsdate.Text );
cmdselect.Parameters.Add("@.story", story.Text );
cmdselect.Parameters.Add("@.wordcount", "1" );


int valueinserted = cmdselect.ExecuteNonQuery();


Response.Redirect("http://declt/websites/c1400046/newpicture.aspx?id="+valueinserted);

con.Close();

as you can see im using the valueinserted but thats just returning 1, but im guessing that means it sucessful. but i want the id of the new record! any idea how ?

Hi,

you need to either specify a RETURN or make the @.newNewsID an output parameter.

Or use the SqlDataReader object like this:

1CREATE PROCEDURE createpost(2 @.userID integer,3 @.categoryID integer,4 @.titlevarchar(100),5 @.newsdatedatetime,6 @.storyvarchar(250),7 @.wordcountint8)9as1011Insert Into TB_News(UserID, CategoryID, title, newsdate, StoryText, wordcount)12Values (@.userID, @.categoryID, @.title, @.newsdate, @.story, @.wordcount)1314SELECT@.@.IDENTITY
and in  code:2con =new SqlConnection ("server=declt; uid=c1400046; pwd=c1400046; database=c1400046");3int valueinserted = 0;45try6 cmdselect =new SqlCommand("createpost", con);7 cmdselect.CommandType = CommandType.StoredProcedure;89 cmdselect.Parameters.Add("@.userID", userID);10 cmdselect.Parameters.Add("@.categoryID", categoryID );11 cmdselect.Parameters.Add("@.title", title.Text );12 cmdselect.Parameters.Add("@.newsdate", newsdate.Text );13 cmdselect.Parameters.Add("@.story", story.Text );14 cmdselect.Parameters.Add("@.wordcount","1" );1516 cmdselect.Connection.Open();17 SqlDataReader reader = command.ExecuteReader();18if( reader.HasRows() )19 {20 reader.Read();21 valueinserted = Convert.ToInt32( reader[0] );22 }23catch( Exception ex)24{25//handle the exception somehow26}27finally28{29if( con !=null and conn.State != ConnectionState.Closed )30 con.Close();31}3233Response.Redirect("http://declt/websites/c1400046/newpicture.aspx?id="+valueinserted);
