Adventure Works 2019: Adding New Person to Person.Person Table - sql-server

Question

Right now I am using 3 stored procedures to Add a person to the person.person table. I would like to cut this down to a single stored procedure to resolve this issue.
INSERT new GUID and DateModified to table Person.BusinessEntity
SELECT the auto generate BusinessEntityID form table Person.BusinessEntity
INSERT new Person to Person.Person Table
The Stored Procedures all use parameters which I pass via a C# application and I have confirmed that the a user is in fact added to the AdventureWorks2019 Db.
Procedure: Person.CreateNewBusinessEntity
INSERT INTO [Person].[BusinessEntity]
(
[BusinessEntity].rowguid
, [BusinessEntity].ModifiedDate
)
VALUES
(
#RowGUID
, GetDate()
)
Procedure: Person.GetBusinessEntityID
SELECT
[BusinessEntityID]
FROM
[AdventureWorks2019].[Person].[BusinessEntity]
WHERE [rowguid] = #RowGuid
Procedure: Person.CreateNewPerson
INSERT INTO [Person].[Person]
(
[BusinessEntityID]
,[PersonType]
,[NameStyle]
,[Title]
,[FirstName]
,[MiddleName]
,[LastName]
,[Suffix]
,[EmailPromotion]
,[AdditionalContactInfo]
,[Demographics]
,[rowguid]
,[ModifiedDate]
)
VALUES
(
#BusinessEntityID
, #PersonType
, #NameStyle
, #Title
, #FirstName
, #MiddleName
, #LastName
, #Suffix
, #EmailPromotion
, #AdditionalContactInfo
, #Demographics
, #RowGUID
, GetDate()
)
Any help here is appreciated. Thanks!
Thanks to HABO, I am now using this solution. Now I only need two procedures.
DECLARE #Inserted table ( [BusinessEntityID] int );
INSERT INTO [Person].[BusinessEntity]
(
[BusinessEntity].rowguid
, [BusinessEntity].ModifiedDate
)
OUTPUT inserted.[BusinessEntityID] INTO #Inserted([BusinessEntityID])
VALUES
(
#RowGUID
, GetDate()
)

Answer 1

The below answer shows you how to get the inserted id and add it to the next insert in side the Same SP.
USE AdventureWorks2012
GO
CREATE PROC CreateNewPerson
AS
BEGIN
DECLARE #OutputTbl TABLE ([BusinessEntityID] INT, ModifiedDate DATETIME)
DECLARE #BusinessEntityID AS INT
INSERT INTO [Person].[BusinessEntity]
(
[BusinessEntity].rowguid
, [BusinessEntity].ModifiedDate
)
--Get the output value inserted to a table.
OUTPUT inserted.[BusinessEntityID], inserted.ModifiedDate INTO
#OutputTbl([BusinessEntityID],[ModifiedDate])
VALUES
(
NEWID()
, GetDate()
)
--Assigned to a variable. You can get this using subquery as well inside the insert statment.
SELECT #BusinessEntityID = [BusinessEntityID] FROM #OutputTbl
INSERT INTO [Person].[Person]
(
[BusinessEntityID]
,[PersonType]
,[NameStyle]
,[Title]
,[FirstName]
,[MiddleName]
,[LastName]
,[Suffix]
,[EmailPromotion]
,[AdditionalContactInfo]
,[Demographics]
,[rowguid]
,[ModifiedDate]
)
VALUES
(
#BusinessEntityID
, #PersonType --These columns with # sign needed to be declared or supply values
, #NameStyle
, #Title
, #FirstName
, #MiddleName
, #LastName
, #Suffix
, #EmailPromotion
, #AdditionalContactInfo
, #Demographics
, NEWID() --This will generate a new GUID for each row.
, GetDate()
)
END
GO
Second way is using Scope_identity(). Replace the
"SELECT #BusinessEntityID = [BusinessEntityID] FROM #OutputTbl'
from below lines in the Sp will do the same thing for you.
SELECT #BusinessEntityID = SCOPE_IDENTITY() --[BusinessEntityID] FROM #OutputTbl
Select #BusinessEntityID
