Solution 1

Assuming that the name of your table is empdata.

SQL

Declare Cursor_EmpIds CURSOR LOCAL FORWARD_ONLY FOR Select distinct empid from empdata;
Declare @CurrentEmpId varchar(80);
Declare @LoopController bit = 0;
Declare @CompareDate date;
Declare @TemporaryTable TABLE (empid varchar(80),DateValue date);
OPEN Cursor_EmpIds;
FETCH NEXT FROM Cursor_EmpIds into @CurrentEmpId;
While @@FETCH_STATUS=0 
BEGIN
	SET @LoopController=0;
	SET @CompareDate=CAST('2013-05-01' as date);
	WHILE @LoopController=0
	BEGIN
		IF (SELECT COUNT(*) from empdata where empid=@CurrentEmpId AND DateValue=@CompareDate)=0
		BEGIN
			INSERT INTO @TemporaryTable VALUES (@CurrentEmpId,@CompareDate);
		END
		Set @CompareDate=DATEADD(day,1,@CompareDate);
		If @CompareDate=CAST('2013-05-11' as date)
		BEGIN
		    SET @LoopController=1;
		END
	END
FETCH NEXT FROM Cursor_EmpIds into @CurrentEmpId;
END
Close Cursor_EmpIds;
SELECT empid,datevalue from EmpData UNION SELECT empid,datevalue from @TemporaryTable order by empid,datevalue;

please change your question according to your requirement and also post what you have done so far to get the result.

Mike Meinz 22-Jun-13 7:02am

I am not sure what you expect me to do. I gave you a solution to your question and now you want me to do your project for you? Please write the code yourself and, if you have difficulty with the syntax, ask questions about it.

Populate date table and then left join with your table

CREATE TABLE DateTable(DateVale DATE)
DECLARE @Mindate DATE = '2013-01-01'
DECLARE @Maxdate DATE = '2013-01-15'

;WITH Dates(DATEPARAM) AS
(
SELECT @Mindate AS DATE
UNION ALL
SELECT DATEADD(DAY, 1, DATEPARAM) FROM Dates WHERE DATEPARAM < @Maxdate
)
INSERT DateTable
SELECT * FROM Dates
