DR_EmployeeID AS EMPID ,
EM_FirstName +' '+ isnull(EM_MiddleName,' ' )+' '+isnull(EM_LastName,' ') AS EMPNAME,

Which database are we using here?

SQL Server does have an isnull function. For oracle checkout nvl. And for mysql I found this discussion of ifnull http://forums.mysql.com/read.php?98,198593

Try COALESCE instead of ISNULL

SELECT DISTINCT DECODE(DR_TimeIn, NULL,'NOT CHECKED',DR_TimeIn) as Date,
.............;

If you are using Oracle DECODE if the best.
OR for other Database Server:

SELECT  IIf(TimeIn is null,'NOT CHECKED',TimeIn) AS [Date],
........;

It looks like you just forgot to wrap EM_FirstName in an isnull. Otherwise I don't see why that wouldn't work with MSSQL.

I may have done you a disservice, seems you have changed to datetime, well done.

Not sure if it will work with datetime but you might try ABS()

you've still not read the forum guidlines, you've still not learnt to use descriptive subject lines, you've still not learned to keep it in 1 thread.

You'll learn nothing from this response so i'll just paste the correction. Im not going to bother testing it, so check the syntax and try to understand it.

CONVERT(VARCHAR(5), ABS((DATEDIFF(SS,MIN(FIRSTTIMEIN),MAX(LASTTIMEOUT)) / 3600)-(SUM(DATEDIFF(SS, FIRSTTIMEIN, LASTTIMEOUT)) / 3600)))

CONVERT(VARCHAR(5), ABS((SUM(DATEDIFF(SS,FIRSTTIMEIN, LASTTIMEOUT)) % 3600 / 60)-(DATEDIFF(SS, MIN(FIRSTTIMEIN), MAX(LASTTIMEOUT)) % 3600 / 60)))

Maybe if you swap both datetime arguments in DATEDIFF, your problem is gone?

It looks like you're trying to get the hour:minute:second difference between two datetime values. The simplest way to do that is subtract them, then convert that value to char and apply the appropriate formatting.

declare @t1 datetime, @t2 datetime

select @t1 = GETDATE()

--Select @t2 = @t1 + 1:02:03 (hh:mm:ss)
select @t2 = DATEADD(hour, 1, dateadd(minute, 2, dateadd(second, 3, @t1)))

select convert(varchar, @t2-@t1, 108)

You can find other formatting options here[^]

Are you asking for something as simple as string functions such as SQL Server's Replace()?

Depending on which database you're using, I'd google "your_database string functions"...

So are you still storing your date data as strings? Or have you done the sensible thing and changed it to a datetime format.

Sorry I already know the answer otherwise you would not be asking this question.

CHANGE YOUR DATE DATA TO DATATIME FORMAT!

Like for example I have 2 columns and one date column. Now I have to write a query in such a way that
the sum(col1), sum(col2) for 1 day ago, 1 week ago and 1month ago in the same row.

Can anybody please help me in writing this query. Any link or any code snippet will be very much helpfull.

Thanks in advance.

Break it into 4 queries, 1 for each time period doing the appropriate aggregation for each query, include the common key. Then join the 4 queries into 1 using the common key. I would use table vars to hold the temp data.

BTW I would not put my company name in your sig, it can be incorrectly construed (look it up).

In other words, it sounds like column 2 is a running total of column 1. There's not a real elegant way that I know of, but it is a common problem.

Did you try a search for SQL running totals[^]?

SQL Select Question

Aptiva Dave7-Jul-10 8:25

Aptiva Dave

7-Jul-10 8:25

Got myself a head scratcher here. I'm needing to pull employee names and pictures from a database, which I can do with the following select:

SELECT     dbo.vwEmployee.BadgeName, dbo.Image.Photo, dbo.vwEmployee.Updated
FROM         dbo.Image INNER JOIN
                      dbo.vwEmployee ON dbo.Image.OwnerGUID = dbo.vwEmployee.OwnerGUID
WHERE     (dbo.vwEmployee.Department = 'IT')

Problem is that the application that was used to store the employee information and photos also keeps every photo taken of the employee. I want to be able to return only the row with the most recent photo taken (or the first instance of the most recent update since some have multiple records with the same updated date). I know I can do this with the application I am writing to use this query, but I would rather let the SQL Server do most of the heavy lifting and to further narrow down my results.

Does the Image table have multiple records or multiple columns for the pictures? If record then does it have a time stamp? If so use a subquery to find the max time and pass that picture.

If you have a date field, then use TOP 1 and ORDER BY update_date DESC.

You need to do a sub-select to get a list of the employees and the date of their most recent picture. Then you join to that on the EmployeeID (OwnerGuid) and the date.

select c.BadgeName, a.Photo, c.Updated
  from Image a
  join (select OwnerGUID, MAX(PictureDate) PictureDate from Image group by OwnerGUID) b on a.OwnerGUID = b.OwnerGUID and a.PictureDate = b.PictureDate
  join vwEmployee c ON a.OwnerGUID = c.OwnerGUID
 where c.Department = 'IT'

UniqueIdentifier Foreign Key

tek 2009

6-Jul-10 23:43

I have two tables: table1 field contains the ID type UniqueIdentifier and table2 contains ID as foreign key when inserting values is not the same values filled in the two table table1 in this ID is filled eg e210d5ad-BC41-439th-b8e8-e8ed775ee932, and in table 2 it is filled with zero
So how do I do to unify all relationships necessary is active
the two queries are:

CREATE Procedure [dbo].[Insert1](@ID uniqueidentifier, @name varchar(10),@tel varchar(10))
AS
INSERT INTO [table1] ([ID], [name], [tel])
VALUES (NEWID(), @name, @tel)

CREATE Procedure [dbo].[Insert2](@ID uniqueidentifier, @cmd1 varchar(20))
AS
INSERT INTO [Table2] ([ID], [cmd1])
VALUES (@ID, @cmd1)

table1: ID Primary key
Table2:ID foreign Key
