Hi,

There are several ways to use transactions. You can do it like this (modified and added code in bold):

SQL

CREATE PROCEDURE [dbo].[InsertRowInPersonelInfo]
(@personelcode varchar (20),@firstname nvarchar(50),@lastname nvarchar(50),
    @employmenttype nvarchar(50),@employmentdate char(10))
AS
BEGIN
	SET NOCOUNT ON;
	SET XACT_ABORT ON;

	BEGIN TRY
	  BEGIN TRANSACTION;
		insert into PersonelInfo(PersonelCode,FirstName,LastName)
		 Values(@personelcode,@firstname,@lastname)

		DECLARE @lstprsnlID INT
		set @lstprsnlID = SCOPE_IDENTITY();

		insert into EmploymentInfo(FK_pID,EmploymentType,EmploymentDate)
		Values(@lstprsnlID,@employmenttype,@employmentdate)
		
	  COMMIT TRANSACTION;
	END TRY

	BEGIN CATCH	
	  IF (XACT_STATE()) = -1
	    ROLLBACK TRANSACTION;
	  ELSE IF (XACT_STATE()) = 1
	    COMMIT TRANSACTION;
	END CATCH;

END		
GO
