Hi,
I would like to ask you do you know how to return a resultset and int value
from Stored Procedure.
If we have a table
Teachers
=========
ID INT PK
NAME VARCHAR(25)
ADDR VARCHAR(75)
I would like to write a SP which must return the @COUNT of all teachers in
the table Teachers and
also the resultset from SELECT NAME FROM TEACHERS WHERE NAME="ADAM". Do you
know how to write this SP?
It must b e something like this:
CREATE STORED PROCEDURE
@NAME VARCHAR(25),
@COUNT INT OUTPUT
AS
SELECT @COUNT=COUNT(*) FROM TEACHERS
SELECT ADDR FROM TEACHERS WHERE NAME='ADAM'
return @COUNT
In the ASP.NET/C# application I do this:
dad.SelectComma nd.Parameters.A dd(new SqlParameter("@ NAME",
SqlDbType.VarCh ar,25));
dad.SelectComma nd.Parameters["@USRNAM"].Value =
Session["usrName"].ToString();
dad.SelectComma nd.Parameters.A dd(new SqlParameter("@ Count", SqlDbType.Int)) ;
dad.SelectComma nd.Parameters["@Count"].Direction =
ParameterDirect ion.Output;
int count = (int)dad.Select Command.Paramet ers["@Count"].Value;
But there is error: Null Reference in the last line.
How can I catch the resultset from the sql query and also the OUTPUT VALUE?
Thank you!
Viktor

hi
hope this will work
CREATE PROCEDURE spGetTeachers
@NAME VARCHAR(25),
@COUNT INT OUTPUT
AS
SET NOCOUNT ON
SELECT @COUNT=COUNT(*) FROM TEACHERS
SELECT ADDR FROM TEACHERS WHERE NAME=@NAME
GO
cnn.Open();
SqlDataAdapter cmd=new SqlDataAdapter( "spGetTeachers" ,cnn);
cmd.SelectComma nd.CommandType =CommandType.St oredProcedure;
SqlParameter param=new SqlParameter ("@NAME",SqlDbT ype.VarChar,50) ;
param.Value ="Adams";
SqlParameter param2=new SqlParameter ("@COUNT",SqlDb Type.Int,8);
param2.Directio n =ParameterDirec tion.Output ;
param2.Value =-1;
cmd.SelectComma nd.Parameters.A dd(param) ;
cmd.SelectComma nd.Parameters.A dd(param2) ;
DataSet ds=new DataSet ();
cmd.Fill(ds);
param2.Value will give the count

Hi Viktor,
Please also note that using the Fill keyword will return the number of
affected rows : graphically create a DataAdapter, and a Dataset
modeled after your teachers table, and then :
dsTeachers myTeachers = new dsTeachers();
int NumberOfAffecte dRecords = daTeachers.Fill (myTeachers);
HTH,
Michel
