Step 1:- Create table
create table EmpTable
(
EmpId int identity,
EmpName varchar(50)
)
Step 2:- Create Procedure
create proc getOutputValue
@EmpName varchar(50),
@LastIdentity int output
as
begin
insert into EmpTable(EmpName)
values(@EmpName)
set @LastIdentity = @@identity
end
Step 3:- Get output parameter value in SQL Server
declare @LastIdentity int
exec getOutputValue 'Employee 4', @LastIdentity output
print @LastIdentity
Step 4:- Get output parameter value in ASP.Net using C#
Step 1:- Default.aspx Code
