Looping through Command Line Results...

I want to run a command line utility and return the results. I'm pretty sure
I
know how to do that. What's the best practice for looping through the results
to find specific information from the results of the command line?
Say I want to search for a string "computername" in each returned row.
Thanks.

There are diverse and contradictory way to interpret your question.
One would be that you want to run SQL Server commands from the command
prompt (sometimes called the DOS prompt). OSQL would let you run the
commands, and it is common to save the results to a .txt file. It is
possible to search a .txt file using the command line utility FIND.
Another interpretation of your question is that you intend to run
something from within SQL Server using xp_cmdshell and wish to search
the results. The approach in that case is to create a table with one
column (varchar(255) and then:
INSERT ThatTable (ThatColumn)
EXEC master..xp_cmdshell 'some command here'
After which you can search the table using SELECT and LIKE. If the
sequence of the rows is significant, include an IDENTITY column in the
table definition so that you can tell which order the rows came in.
A third interpreation could be that your question has nothing to do
with SQL Server and belongs somewhere else.
Perhaps you would like to clarify?

|||Roy,
Thank you, and sorry for being unclear. The second answer is what I was
planning
and how I will do it. I just wasnt sure if I ran xp_cmdshell if I could
just loop
through the results without having to populate a table.
Thanks again.

Lookup UDF

Hi,
Can anybody provide me a Lookup UDF? I need to supply columnname,Tablename and condition dynamically and I need the scalar value in return.
Any help will be greatly appreciated...Hello again Rudra - I very recently commented on you not being around much these days :)

I have a suspicion about what you want to do and it is probably bad and likely impossible if interpreted literally. Do you want to supply a column name, table name, a key value to a function and get an alternate key value in return (i.e. have some dynamic SQL within the UDF)? If not please can you give more details about what you want this function to actually do.|||Hello again Rudra - I very recently commented on you not being around much these days :)

Thanks Pootle.:p It seems just like the old days.
Yea ,I was not around for a long time.But I always find the Yak Corral's B-E-A-U-T -Y Bcoz it always goes on and on and on...

Well,I know what I am trying to do is quite impossible but can you suggest me a way by which I can fetch a value in by lookup UDF or something like that in a long script?
In one of the script there are no of cases where things are done in this way-
case when Policy.FinanceID = 0 Then ' ' else 'Finance Co.: ' + (select name from Finance where financeId= policy.financeid)Can I use something else for that line?|||In one of the script there is no of cases where things are done in this way-
case when Policy.FinanceID = 0 Then ' ' else 'Finance Co.: ' + (select name from Finance where financeId= policy.financeid)Can I use something else for that line?Well, not knowing any more about your problem, the easiest thing would be to insert the data into the table.

INSERT Finance (financeId, name)
SELECT 0, ''
This also covers a bug bear of mine which is sticking your data into code. (linky: http://weblogs.sqlteam.com/jeffs/archive/2006/02/10/9002.aspx) Otherwise you could create a view:

CREATE VIEW finance_x
AS
SELECT financeId, name
FROM finance
UNION ALL
SELECT 0, ''
and use that.|||Hmm... that link was great :cool: thanks a lot Pootle...see u soon.

Looking for how to return the previous payment

I use the following sql in a view to return the last payment date and amount made by clients. What I need is a way to return the payment date and amount for the payment prior to the last one.

Any help is appreciated very much,

SELECT dbo.tblPaymentReceipts.Client_ID, dbo.tblPaymentReceipts.PaymentDateAS LastPayDate,SUM(dbo.tblPaymentReceipts.AmountPaid)AS LastPayAmt
FROM dbo.tblPaymentReceiptsINNERJOIN
(SELECT Client_ID,MAX(PaymentDate)AS LastPayDate
FROM dbo.tblPaymentReceiptsAS tblPaymentReceipts_1
GROUP BY Client_ID)AS AON dbo.tblPaymentReceipts.Client_ID = A.Client_IDAND dbo.tblPaymentReceipts.PaymentDate = A.LastPayDate
GROUP BY dbo.tblPaymentReceipts.Client_ID, dbo.tblPaymentReceipts.PaymentDate

You could try something like this...

SELECT
X.ClientID,
P.PaymentDate AS ThisPaymentDate,
P.Amount AS ThisPaymentAmount,
L.PaymentDate AS LastPaymentDate,
L.Amount AS LastPaymentAmount
FROM
(
SELECT
ClientID,
MAX(PaymentDate) AS PaymentDate
FROM tblPaymentReceipts
GROUP BY ClientID
) AS X
LEFT JOIN
(
SELECT
R.ClientID,
Max(R.PaymentDate) AS PaymentDate
FROM
(SELECT ClientID, MAX(PaymentDate) AS PaymentDate FROM tblPaymentReceipts GROUP BY ClientID) AS Z
LEFT JOIN tblPaymentReceipts R
ON Z.ClientID = R.ClientID
AND R.PaymentDate < Z.PaymentDate
GROUP BY R.ClientID
) AS Y
ON X.ClientID = Y.ClientID

LEFT JOIN tblPaymentReceipts P
ON X.ClientID = P.ClientID
AND X.PaymentDate = P.PaymentDate

LEFT JOIN tblPaymentReceipts L
ON Y.ClientID = L.ClientID
AND Y.PaymentDate = L.PaymentDate

This most likely isn't the most efficient query but its a starting point for you...

--SQL Server 2005

SELECT Client_ID, PaymentDate, AmountPaidFROM(SELECT Client_ID, PaymentDate, AmountPaid, ROW_Number()OVER(PARTITIONBY Client_IDORDERBY PaymentDateDESC)as RowNum

FROM tblPaymentReceipts)AS t

WHERE RowNum=2--RowNum=1 for latest payment

-- If you are not using SQL Server 2005:

SELECT Client_ID, PaymentDate, AmountPaidFROM(SELECT Client_ID, PaymentDate, AmountPaid,

(SELECTCOUNT(*)FROM tblPaymentReceiptsAS a

WHERE(PaymentDate>= b.PaymentDate)AND(Client_ID= b.Client_ID))AS RowNum

FROM tblPaymentReceiptsAS b

)AS t

WHERE RowNum= 2--RowNum=1 for latest payment

These options are much faster to run, however, they are not supoorted as views and I need this to work in a view. the OVER is not supported in SQL Server Express and/or Views.

Dave's option is not as fast but will work in a view.

Thank you both very much,

--SQL Server 2005

CREATEVIEW [dbo].[View_2]

AS

SELECT Client_ID, PaymentDate, AmountPaid

FROM(SELECT Client_ID, PaymentDate, AmountPaid, ROW_Number()OVER(PARTITIONBY Client_ID

ORDERBY PaymentDateDESC)AS RowNum

FROM tblPaymentReceipts)AS t

WHERE RowNum= 2

It shows the error message of OVER not supported at the IDE window, but the view will run correctly.

perhaps I misunderstood the problem, but I thought he was trying to return BOTH the current payment and the previous payment info.?

You are right.

As long as he can work along these logics, it should be straight to get customized results.
