Employee Monthly Attendance Using SQL Server - sql

Question

I have two tables, one is Tab_Users containing user details and the other is Tab_CardEntry containing their card entries. I need to get their minimum and maximum card entry time for each user on a daily basis.
Here is the SQL query I used
SELECT
A.Name,
ISNULL(CONVERT(VARCHAR, MIN(B.DATED), 108), 'OFF') LOGEDIN,
ISNULL(CONVERT(VARCHAR, MAX(B.DATED), 108), 'OFF') LOGEDOUT
FROM TAB_USERS A
LEFT OUTER JOIN (
SELECT
USERNAME,
DATED
FROM TAB_CARDENTRY
WHERE CONVERT(VARCHAR, DATED, 106) = CONVERT(VARCHAR, '02 Jan 2014', 106)
) B ON A.USERNAME = B.USERNAME
GROUP BY A.Name
ORDER BY 1
I need this type of output

Here is a Stored Proc that you can try
CREATE PROCEDURE usp_GetTimes #StartDate DATETIME, #EndDate DATETIME = NULL
AS
BEGIN
--Make sure that only 31 days of data is used otherwise the temp table will be too big
IF #EndDate IS NULL OR DATEDIFF(dd, #StartDate, #EndDate) > 31
SET #EndDate = DATEADD(dd, 31, #StartDate)
SELECT UserID, CONVERT(DATETIME, FLOOR(CONVERT(FLOAT, DateTimeIn))) ForDate, DateTimeIn, DateTimeOut
INTO #Times
FROM
(
SELECT DISTINCT MIN(a.DATED) OVER (PARTITION BY a.USERNAME, CONVERT(DATETIME, FLOOR(CONVERT(FLOAT, DATED)))) DateTimeIn,
MAX(a.DATED) OVER (PARTITION BY a.USERNAME, CONVERT(DATETIME, FLOOR(CONVERT(FLOAT, DATED)))) DateTimeOut,
USERNAME AS UserID
FROM TAB_CARDENTRY a
WHERE DATED BETWEEN #StartDate and #EndDate + 1
) a
SELECT DISTINCT ForDate INTO #Dates FROM #Times
--Select * from #Times order by 1
--Select * from #Dates
DECLARE #SQLstring VARCHAR(MAX)
SET #SQLstring = 'CREATE TABLE ##Test (UserID varchar(10), '
DECLARE #ForDate DATETIME
WHILE 0 < (SELECT COUNT(*) FROM #Dates)
BEGIN
SET ROWCOUNT 1
SELECT #ForDate = ForDate FROM #Dates order by ForDate
SET ROWCOUNT 0
SET #SQLstring = #SQLstring + '[Entry ' + CONVERT(VARCHAR(12), #ForDate, 106) + '] datetime, [Exit ' + CONVERT(VARCHAR(12), #ForDate, 106) + '] datetime,' + CHAR(13) + CHAR(10)
DELETE #Dates WHERE ForDate = #ForDate
END
SET #SQLstring = SUBSTRING(#SQLSTRING, 1, LEN(#SQLSTRING) - 3) + ')'
EXEC (#SQLstring)
CREATE INDEX idx1 on ##Test(UserID)
DECLARE #UserID VARCHAR(10),
#DateIn DATETIME,
#DateOut DATETIME
WHILE 0 < (SELECT COUNT(*) FROM #Times)
BEGIN
SET ROWCOUNT 1
SELECT #UserID = UserID, #DateIn = DateTimeIn, #DateOut = DateTimeOut, #ForDate = ForDate from #Times
SET ROWCOUNT 0
SET #SQLString = 'IF NOT EXISTS(SELECT 1 FROM ##Test WHERE UserID = ''' + #UserID + ''')' + CHAR(13) + CHAR(10) +
' INSERT ##Test (UserID, [Entry ' + CONVERT(VARCHAR(12), #ForDate, 106) + '], [Exit ' + CONVERT(VARCHAR(12), #ForDate, 106) + ']) ' +
' SELECT ''' + #UserID + ''', ''' + CONVERT(VARCHAR(20), #DateIn, 113) + ''', ''' + CONVERT(VARCHAR(20), #DateOut, 113) + '''' + CHAR(13) + CHAR(10) +
'ELSE' + CHAR(13) + CHAR(10) +
' UPDATE ##Test SET [Entry ' + CONVERT(VARCHAR(12), #ForDate, 106) + '] = ''' + CONVERT(VARCHAR(20), #DateIn, 113) + ''', ' + CHAR(13) + CHAR(10) +
' [Exit ' + CONVERT(VARCHAR(12), #ForDate, 106) + '] = ''' + CONVERT(VARCHAR(20), #DateOut, 113) + ''' WHERE UserID = ''' + #UserID + ''''
EXEC (#SQLstring)
DELETE #Times WHERE UserID = #UserID AND ForDate = #ForDate
END
SELECT * FROM ##Test ORDER BY 1
DROP TABLE ##Test
END
EDIT
I've looked at the query again and you might not like the output, so you can change a part of the SP to look like this:
The part that creates the temp table
WHILE 0 < (SELECT COUNT(*) FROM #Dates)
BEGIN
SET ROWCOUNT 1
SELECT #ForDate = ForDate FROM #Dates order by ForDate
SET ROWCOUNT 0
SET #SQLstring = #SQLstring + '[Entry ' + CONVERT(VARCHAR(12), #ForDate, 106) + '] varchar(20), [Exit ' + CONVERT(VARCHAR(12), #ForDate, 106) + '] varchar(20),' + CHAR(13) + CHAR(10)
DELETE #Dates WHERE ForDate = #ForDate
END
And the part that inserts the data into the table
WHILE 0 < (SELECT COUNT(*) FROM #Times)
BEGIN
SET ROWCOUNT 1
SELECT #UserID = UserID, #DateIn = DateTimeIn, #DateOut = DateTimeOut, #ForDate = ForDate from #Times
SET ROWCOUNT 0
SET #SQLString = 'IF NOT EXISTS(SELECT 1 FROM ##Test WHERE UserID = ''' + #UserID + ''')' + CHAR(13) + CHAR(10) +
' INSERT ##Test (UserID, [Entry ' + CONVERT(VARCHAR(12), #ForDate, 106) + '], [Exit ' + CONVERT(VARCHAR(12), #ForDate, 106) + ']) ' +
' SELECT ''' + #UserID + ''', ''' + CONVERT(VARCHAR(20), ISNULL(#DateIn, '''OFF''', 108) + ''', ''' + CONVERT(VARCHAR(20), ISNULL(#DateOut, '''OFF'''), 108) + '''' + CHAR(13) + CHAR(10) +
'ELSE' + CHAR(13) + CHAR(10) +
' UPDATE ##Test SET [Entry ' + CONVERT(VARCHAR(12), #ForDate, 106) + '] = ''' + CONVERT(VARCHAR(20), ISNULL(#DateIn, '''OFF'''), 108) + ''', ' + CHAR(13) + CHAR(10) +
' [Exit ' + CONVERT(VARCHAR(12), #ForDate, 106) + '] = ''' + CONVERT(VARCHAR(20), ISNULL(#DateOut, '''OFF''', 108) + ''' WHERE UserID = ''' + #UserID + ''''
EXEC (#SQLstring)
DELETE #Times WHERE UserID = #UserID AND ForDate = #ForDate
END
