How to change stored procedure with Table Valued Parameter

Question

I am not sure how to change the normal stored procedure with Table Value Parameter.Do I have to create a separate Table or do I have to create a datatype. Can you please help me with this
ALTER PROCEDURE [dbo].[uspInsertorUpdateINF]
@dp_id char(32),
@dv_id char(32),
@em_number char(12),
@email varchar(50),
@emergency_relation char(32),
@option1 char(16),
@status char(20),
@em_id char(35),
@em_title varchar(64),
@date_hired datetime
AS
BEGIN
SET NOCOUNT ON;
MERGE [dbo].[em] AS [Targ]
USING (VALUES (@dp_id, @dv_id , @em_number, @email, @emergency_relation, @option1, @status, @em_id, @em_title, @date_hired))
AS [Sourc] (dp_id, dv_id, em_number, email, emergency_relation, option1, status, em_id, em_title, date_hired)
ON [Targ].em_id = [Sourc].em_id
WHEN MATCHED THEN
UPDATE
SET dp_id = [Sourc].dp_id,
dv_id = [Sourc].dv_id,
em_number = [Sourc].em_number,
email = [Sourc].email,
emergency_relation = [Sourc].emergency_relation,
option1 = [Sourc].option1,
status = [Sourc].status,
em_title = [Sourc].em_title,
date_hired = [Sourc].date_hired
WHEN NOT MATCHED BY TARGET THEN
INSERT (dp_id, dv_id, em_number, email, emergency_relation, option1, status, em_id, em_title,date_hired)
VALUES ([Sourc].dp_id, [Sourc].dv_id, [Sourc].em_number, [Sourc].email, [Sourc].emergency_relation, [Sourc].option1, [Sourc].status, [Sourc].em_id, [Sourc].em_title, [Sourc].date_hired);
END;

Answer 1

It's not clear how you would change the procedure. But assuming that you want to replace the existing scalar parameters with tabular input, this is how you would do it. You first create a table type:
CREATE TYPE  Insertor_type AS TABLE
    (dp_id                char(32),
     dv_id                char(32),
    em_number            char(12),
    email                varchar(50),
    emergency_relation   char(32),
    option1              char(16),
    status               char(20),
    em_id                char(35),
    em_title             varchar(64),
    date_hired           datetime)
Then you change the procedure header:
ALTER PROCEDURE [dbo].[uspInsertorUpdateINF] @tvp Insertor_type READONLY AS
And finally you change the USING clause:
   USING (SELECT dp_id, dv_id , em_number, email, emergency_relation, option1, status, em_id, em_title, date_hired
          FROM   @tvp) AS [Sourc] ON [Targ].em_id = [Sourc].em_id
The rest is fine as it is.
