Hi Vikas,<br />
<br />
Since the spreadsheet contains only headers, it looks like you just need the syntax. &nbsp;Easy enough.<br />
<br />
WITH MyCTE (Code, NextEffectiveType, NextEffectiveCycleDate)<br />
AS<br />
(<br />
&nbsp; SELECT statement<br />
)<br />
SELECT * FROM MyCTE<br />
<br />
<br />
Good Luck,<br />

Hi Vikas,<br />
<br />
This looks very much like classwork/homework. &nbsp;As such, I'm limited by the amount of help that I can give you. &nbsp;I can help, but the work has to be yours.<br />
<br />
Where do we begin? &nbsp;What don't you understand?
</div>


<div>
Can you provide me with a CTE Query for the xl i have provided to you. I have explained the scenario in the xl sheet itself
</div>


<div>
Hi Vikas,<br />
<br />
I refer you to Chapter 6, item 16 (6-16) in the site's Terms of Use.<br />
<br />
&nbsp; <a href="https://www.experts-exchange.com/terms.jsp" rel="ugc">https://www.experts-exchange.com/terms.jsp</a><br />
<br />
I can help and I can teach. &nbsp;But since I believe this to be an academic assignment I cannot do it for you.
</div>


<div>
This is not an academic question. Seriously i am in a hurry and is a tonned down version of the bigger query.<br />
<br />
Request you to please help me in this.<br />
<br />
Thanks
</div>


<div>
Well, given your spread sheet, the following will work.<br />
<br />
However, it needs to be pointed out there are a lot of assumptions...<br />
<br />

<pre><code class="code-10 nolinks" id="code-20-39893768-1"><span>;with cte_balance as </span>
<span>( select row_number() over (order by a.month) as rn, a.month,a.expense,b.po,a.expense+b.po as total</span>
<span>  from TableA a</span>
<span>  left outer join TableB b on a.month = b.month</span>
<span>)</span>
<span>select c.rn, c.month, c.expense</span>
<span>     , case when c.po is null then c.expense - p.total else c.po end as po</span>
<span>     , case when c.po is null then p.total else c.total end as total</span>
<span>from cte_balance c</span>
<span>left outer join cte_balance p on c.rn - 1 = p.rn </span>
</code></pre>
<br />
Do you want to discuss your requirement in more detail, or some of the potential traps &nbsp;?<br />
<br />
As a matter of interest, I am confused with the spreadsheet results, total column might be a running total, but taking two months into account, 25,000 + 7,000 it is very hard to get to the totals indicated. But up to you.
</div>


<div>
The query works fine with one exception. <br />
<br />
The basic calculation is as follows:<br />
<br />
PO:<br />
if there is a PO amount in Table B for that month it should take that amount else<br />
it should take the previous row total amount - the expense of that row<br />
<br />
Total:<br />
it is the expense + po of that row.<br />
<br />
this should happen for each row in table A. <br />
<br />
In the query you have provided the last month is blank.<br />
<br />
Thanks
</div>


<div>
Here are my results from the above :<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-39893913-1"><span>1	2013-10-01 00:00:00.000	10000.00   7000.00   17000.00</span>
<span>2	2013-11-01 00:00:00.000	15000.00   -2000.00   17000.00</span>
<span>3	2013-12-01 00:00:00.000	0.00      3000.00   3000.00</span>
</code></pre>
<br />
Not sure what you mean by &quot;last month is blank&quot;<br />
<br />
Blank PO, I calculated this as &quot;expense - last total&quot;, and can just swap that arithmetic.<br />
<br />
Blank PO for total will always be the same as prior total. e.g<br />
15000 + (17000 - 15000) = 17000 so that 2nd case statement is still correct.<br />
<br />
I think all we need is the first &quot;case&quot; statement becomes <b>p.total - c.expense</b> instead of c.expense - p.total (which was a guess from your spreadsheet being a different colour).<br />
<br />
So, that leaves &quot;the last month is blank&quot; comment being a mystery to me.<br />
<br />
Maybe some more test data including current expense, but no PO, and greater than prior total ? And a few more rows ?
</div>


<div>
iF you remove the record of 3000 from the table b you shall get the last row as blank means the Po and Total is coming as null.<br />
<br />
Which should have been 17000 in both PO and Total columns because it should take the previous month total.<br />
<br />
One more thing is that Expense column can be zero also and records in table A are not static. There will be one record for each month in Table A
</div>


<div>
Everything is working. But when I delete records from table b the result is not coming. Forgot to mention records in table b are optional.
</div>


<div>
Yep, understood they were optional, and mine works fine here. <br />
<br />
Well, fine in so much as delete all of TableB then it still runs, just that PO and Total are NULL.<br />
<br />
Also, tried adding a few different rows in TableA and seems to be generating the right results as far as I can tell.<br />
<br />
So, why not prep a couple of spreadsheets with dummy data and expected results ?<br />
<br />
And/or show me your real query :)
</div>


<div>
If there are no records in table b then it should calculate like the condition when the po is null means<br />
<br />
If no po found for that row than it will be previous row total - expense and total for that row would be expense + po
</div>
