Select Random records from Table without repetition in SQL Server

Hi,

I have selected record based of person Birthday month. I have created SelectedPerson for preventing from repeated record.(i.e. if record exists in this table denotes that records already selected)

CREATE TABLE SelectedPersons([Month] INT,PersonId INT)

then created procedure to get records, below procedure gives records based on person birthday month and if its Id does not exists in SelectedPersons Table,if all the records from the Person table are inserted into SelectedPerson table,then it deletes all records form SeletcedPerson Table,and start the same process again

-- EXEC GETPesrsonsBasedOnBirthMonth 1
CREATE PROCEDURE GETPesrsonsBasedOnBirthMonth 
	@Month INT
AS
BEGIN	
	SET NOCOUNT ON;
		
		IF (SELECT COUNT(Id) FROM PersonTable WHERE DATEPART(MONTH,BirthDay) = @Month) <> 0
		BEGIN

			GETPersons: -- This is GOTO Statement Label

			SELECT TOP 3 * 
			INTO #temp 
			FROM PersonTable  
			WHERE DATEPART(MONTH,BirthDay) = @Month
			AND Id NOT IN (SELECT PersonId FROM SelectedPersons WHERE [Month] = @Month)
			ORDER BY NEWID()

			IF (SELECT COUNT(Id) FROM #temp) > 0
			BEGIN
				INSERT INTO SelectedPersons
				SELECT @Month,Id FROM #temp
			END
			ELSE 
			BEGIN
				DELETE FROM SelectedPersons WHERE [Month] = @Month
				DROP TABLE #temp
				GOTO GETPersons
			END
			SELECT * FROM #temp
			DROP TABLE #temp			
		END
END
GO
