Is it possible not to specify format file?

Can we skip format file (-f switch) at all?

I got it working by indicating column tye SQLVAR instead of SQLINT and let SQL do conversion herself - however it's still ridiculous having (mandatory) to specify format file...?

Thanks

Hi,

There's multiple ways of calculating a running total. This article[^] shows three of those solutions.

Not sure how this differs from your earlier question http://www.codeproject.com/Messages/3527850/Complex-Query.aspx[^]

You're looking for running totals.

Not a full solution, but a step towards it:
Let us assume a table "Table1" with following columns and values:

ID val total
 1  12 <NULL>
 2  23 <NULL>
 3   2 <NULL>
 4  14 <NULL>

Now you can update the "total" column for each row with a query like the one below for ID=3:

UPDATE    table1
SET       total = tmp.result
FROM      (SELECT   MAX(ID) AS maxid, SUM(val) AS result
                    FROM          Table1
                    WHERE      (ID <= 3)) TMP
WHERE     table1.id = tmp.maxid

Next, replace "3" by a parameter and run the query for every ID value...

What with a cursor or a while loop, what happens if he has 100k IDs. This is a bad solution, using the running total tools will give a much better result.

I'm currently maintaining a Visual Basic project that makes use of tnsping. In order to do a tnsping, it uses a ProcessStartInfo instance to make the call as if it were using the command prompt(DOS). I was wondering if a library exists (Oracle.DataAccess maybe?) or if there's something built into the .NET libraries that will allow me to do the tnsping without the ProcessStartInfo. Could anyone point me in the right direction?

Thanks in advance for all of your answers.

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

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.

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).
