I need a quick example of writing a stored procedure that inserts a record. then returns the primary key. Please no links.

The primary key is an integer that autofills in increments.

Check this code

Raj
CREATE TABLE YourTable
(
	ID INT IDENTITY(1,1),
	NAME VARCHAR(50)
)


CREATE PROCEDURE usp_InsertRecord
(
	@name	VARCHAR(50)
	@newID	INT OUTPUT
)
AS
BEGIN
	INSERT INTO YourTable (name) VALUES (@name)

	SET @newID = SCOPE_IDENTITY()
END
GO

Write your stored procedure and then at the end put

SELECT @@IDENTITY


For example:

CREATE PROCEDURE TestProcedure
      -- Add the parameters for the stored procedure here
AS
BEGIN
      -- SET NOCOUNT ON added to prevent extra result sets from
      -- interfering with SELECT statements.
      SET NOCOUNT ON;

    -- Insert statements for procedure here
      INSERT INTO TestTable (column1, column2) VALUES ('test1', 'test2')

SELECT @@IDENTITY
END


If you are returning this to an application you are writing, you would change the SELECT @@IDENTIY to
SET @VariableName = SELECT @@IDENTITY

I couldn't get it to work. Yes it is for an application.

I'm using this to get the returned value in the application.

Dim strCert As String = command.Parameters("RetVal").Value

		@DateAdded datetime
	)

BEGIN
	SET NOCOUNT ON;
	DECLARE @RetVal As int
	DECLARE @RetID As int

Add one output parameter to your stored procedure
@RetVal INT OUTPUT
And remove its declaration inside Stored procedure

I think coding part will look like attached

Raj
Dim parameter As SqlParameter = command.Parameters.Add("@Retval", SqlDbType.Int)
parameter.Direction = ParameterDirection.Output
command.CommandText = "sp_AddRecord"
command.ExecuteNonQuery()
Dim outResult As String = parameter.Value.ToString()

Using an IF statement in the stored procedure prevents SQL from reusing the cached execution plan which slows the server down.  I'd recommend the following:

I tried the last 3 solutions, but they give me the ID field of the Company table. I need the primary key of the Certification table (certID).

I will still be using the @RetID to link the tables.

Thanks for the help so far.
