Transact SQL :: Arithmetic Calculation Between Two Rows And Result In Alias Column?
Jul 12, 2015
I am trying to compare Sales value of year 2015 with sales value of 2016 and the difference stored in alias column as Sales_growth for year 2016 , for year 2015 the alias column be as '1' similarly difference between margin of 2015 and 2016 and result stored in alias column as margin_rate in year 2016for 2015 as 1 but when there is no record for year 2015 and record present in 2016 for a given (month, SM,SG,CUST,SP) then the alias column sales_growth and margin_rate should be 100
last record : as there is no record for year 2015 and record present in 2016 for a given (month, SM,SG,CUST,SP) then the alias column sales_growth and margin_rate should be 100
Is there a way to use a column alias in an another calculation within thesame query? Since I am using some long and complex logic to compute total1and total2, I don't want to repeat the same logic to compute the ratio ofthose two columns. I know that I can do a nested query, but that seems toolengthy as well since I actually have many, many columns.selecttotal1 = sum(case(long complex logic)),total2 = sum(case(another long complex logic)),ratio = total1/total2
I have a clustered index in a table. this column is of datatype date. how can i retrieve the following?:
select [date], valueColumn from myTable where [date] = '2000-01-03' and ('2000-01-03'+1) and ('2000-01-03'+2)
My Goal ist to retrieve 3 values of valueColumn of 3 subsequent days, calculate the average of this 3 values and insert this average in a third colum called [average3days].
This is on SQL Server 2008. Please find a detailed description and the file of the data, that I am working on.
Requirements:
1. If 'Channel' is not equal to "Omnibus" where the 'Trans Description'is equal to "Purchase" and "Redemption" for one purchase and one redemption that match on 'System' , 'Account TA Number' , 'Product Name' , 'Settled Date' , and where the 'Trade Amount' of the purchase and redemption is within 5%, then display those set of records.
2. If deemed wash trades, allow user to update the purchase and redemption pair 'Trans Description' from "Purchase" to "Exchange In" and 'Trans Description' from "Redemption" with "Exchange out"
System Channel Dealer Name Firm Name Product Cusip Product Name Product Share Class Trade ID Settled Date Account TA Number Trans Description Trade Amount

I have questions and answers from one table, I need to select questions as column names and answers column values as the results for the questions column.
I am interested in changing the way that data is displayed in my result set.Essentially I want to display a selection of rows (1 to n) as columns, the following diagram explains my intentions.Perhaps one of the greatest challenges here is the fact that I do not have a concrete number of rows (or BIN numbers). Each stock item could be stored in one or more BINS, which I will not know until running my query.
I am having issues trying to write a query that would provide me the unique GUID numbers associated with a distinct PID if the unique GUID's > 1. To summarize, I need a query that just shows which PID's have more than one unique GUID. A PID could have multiple GUID's that are the same, I'm looking for the PID's that have multiple GUID's that are different/unique.

I have the table below and like to combine the rows to create a single link row in a new column. The rows should be combined based on the job number columns which is the same for the rows to be combined.
DECLARE @M31 ( M31_SQL_ID INT ,JOB_NUMBER INT ,LINE_NUMBER INT ,WORKS_DESC VARCHAR)
[Code] ...
Output should be as below
219242 16/7/15 called tenant and she thought we would just fix for free - advised her I can get a quote how ever she may have to pay - she will call back
219245 16/7/15 called tnt said no report number. Said she will speak with her husband and call back with her decision and 16/07/15 the work order was sent to agent ...
I have a TableA where data get inserted from Excel(IMPORT/EXPORT wizard)
TableA; ID(identity) Date (NOT NULL Defaulyt Getdate() ) Name Phone 1 2014-06-17 17:28:21.190 Nick 12345678910 2 2014-05-17 17:28:21.190 Stan 00045678910 3 2015-08-17 17:28:21.190 Kim 11111678910 4 2015-08-17 17:28:21.190 Tom NUll
3,4 are the rows i have inserted now , you can see by date, likewise i have 100,000 rows(old and new combination) and now the data from excel to TableA can be imported/exported daily , hourly, weekly basis.
Now i want to find out only the rows which are imported to tableA today, or hours back, or yesterday .....
the reason is ,
Step1:get data from excel and import to tableA( this is a manual Step) and i know when the data is inserted with exact date and time.
Step2: get newly inserted rows from TableA and pass them as Parameters in Stored Procedure.( i may run step 2 after 1 hour, or after 1 day or after 1 week ,but i want only rows that are inserted )
I tried with using where Datecreated, but did work.
How can I write it in SQL? I have a table that column A has two values of Product and Cost...Where value of A is Product, I have to add 6 more rows, and add column b with values from 1 to 7 for each rows ( counter)Where value of A is Cost, I have to add 4 more rows, and add column b with values from 1 to 5 for each rows ( counter).
I have a view that does some calculations on data in the database. Note in the two code snippets, that the columns being used in the calculations are all type FLOAT(53).
My confusion stems from the fact that both code snippets should be functionally the same in my "view" (*snicker* I kill me...), but they return different results which I think are related to rounding issues.
The first snippet:
CREATE VIEW dbo.VIEW_Calculate_PortfolioIndex AS SELECT PP.PortfolioID AS PortfolioID, PP.CreateDate AS CreateDate, (ROUND((PPI.CloseIndex + (PPI.CloseIndex * PP.DailyPerChg / 100.00)), 2) * PP.AvgHighPriceRatio) AS HighIndex, CASE WHEN PPI.CloseIndex IS NULL THEN 100.00 ELSE ROUND((PPI.CloseIndex + (PPI.CloseIndex * PP.DailyPerChg / 100.00)), 2) END AS CloseIndex, (ROUND((PPI.CloseIndex + (PPI.CloseIndex * PP.DailyPerChg / 100.00)), 2) * PP.AvgLowPriceRatio) AS LowIndex, PP.Volume as Volume FROM dbo.PortfolioIndex PPI INNER JOIN dbo.PortfolioPerformance PP ON PPI.PortfolioID = PP.PortfolioID AND PPI.CreateDate = PP.PrevDate GO
and it's result set: PortfolioIDCreateDateHighIndexCloseIndexLowIndexVolume 102/20/2004781.11774.17769.53527896 112/20/2004757.97750.36742.93605740 122/20/2004509.92501.72494.854180516 132/20/2004988.23980.65973.58632337 142/20/20041283.261269.571259.37416145
And the second snippet:
CREATE VIEW dbo.VIEW_Calculate_PortfolioIndex AS SELECT PP.PortfolioID AS PortfolioID, PP.CreateDate AS CreateDate, (CloseIndex * PP.AvgHighPriceRatio) AS HighIndex, CASE WHEN PPI.CloseIndex IS NULL THEN 100.00 ELSE ROUND((PPI.CloseIndex + (PPI.CloseIndex * PP.DailyPerChg / 100.00)), 2) END AS CloseIndex, (CloseIndex * PP.AvgLowPriceRatio) AS LowIndex, PP.Volume as Volume FROM dbo.PortfolioIndex PPI INNER JOIN dbo.PortfolioPerformance PP ON PPI.PortfolioID = PP.PortfolioID AND PPI.CreateDate = PP.PrevDate
which returns a different result set: PortfolioIDCreateDateHighIndexCloseIndexLowIndexVolume 102/20/2004784.52774.17772.89527896 112/20/2004755.64750.36740.64605740 122/20/2004512.43501.72497.294180516 132/20/2004989.77980.65975.1632337 142/20/20041285.991269.571262.05416145
Specifically, I am concerned with the HighIndex and LowIndex values...since the only modification between the two code snippets is that in the second one, the HighIndex and LowIndex calculations use the column name of CloseIndex (as calculated in the select) in the calcs for those two columns, rather than repeating the code used to calculate the CloseIndex column's value.
I am confused as to why the results of the HighIndex and LowIndex caculations are different in the two selects, when the only change (in my view/expectations) is that one references the CloseIndex column, and the other one just reproduces the calculation itself
I am writing a query where I am identifying different scenarios where data changes between one week and the next. I've set up my result set in the following manner:
PrimaryID Field Changed Previous Value New Value 10003 SKUName SKU12345 SKU56789 10003 LocationId Den123 NYC987 etc...
The key here being that in the initial resultset ID 10003 is represented by one row but indicates two changes, and in the final output those two changes are being represented by two distinct rows. Obviously, I will bring in the previous and new values from a source.
I've put a SelectCommand with an aggregate function calculation and AS into a SqlDataSource and was able to display the result of the calculation in an asp:BoundField in a GridView; there was an expression after the AS (not sure what to call it) and that expression apparently took the calculation to the GridView (so far so good). If I write the same SELECT statement in a C# code behind file, is there a way to take the aggregate function calculation and put it into a double variable? Possibly, is the expression after an AS something that I can manipulate into a double variable? My end goal is to insert the result of the calculation into a database. What I have so far with the SelectCommand, the SqlDataSource and the GridView is shown below in case this helps: <asp:GridView class="gridview" ID="GridView2" runat="server" AutoGenerateColumns="False" DataSourceID="lbsgalDataSource"> <Columns> <asp:BoundField DataField="Formulation" HeaderText="Formulation" SortExpression="Formulation" /> <asp:BoundField DataField="lbs" HeaderText="lbs" SortExpression="lbs" /> <asp:BoundField DataField="gal" HeaderText="gallons" SortExpression="gal" /> <asp:BoundField DataField="density" HeaderText="density" SortExpression="density" />
</Columns> </asp:GridView>
<asp:SqlDataSource ID="lbsgalDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT a.Formulation, SUM (a.lbs) AS lbs, SUM ((a.lbs)/(b.density)) AS gal, ( ( SUM (a.lbs) ) / ( SUM ((a.lbs)/(b.density)) ) ) AS density FROM Formulations a INNER JOIN Materials b ON a.Material=b.Material WHERE Formulation=@Formulation GROUP BY Formulation">
this query is running fine in 2008 , but its not working in 2005 below is the error Msg 8115, Level 16, State 2, Line 1 Arithmetic overflow error converting expression to data type int.there is some problem in converting date in cte

It just takes a LOT of time in SQL Server Management studio. I have to cancel the query and cancelling takes a whole lot time. I am using SQL Server 2008.
I have a table that is used to build rules. The rules point to other columns in other tables and usually contain only one value (i.e. ABC). But one of the options is to add a comma-separated list of SSNs (i.e. 123123123,012012012,112231122). I am trying to build a single query that allows me to leverage that list to get multiple rows from another table.
This obviously works:
SELECT * FROM vw_Person_Profile P (NOLOCK) WHERE P.PrsnPIISSN_Chr IN ('123123123','012012012','112231122')
But this does not:
SELECT * FROM vw_Person_Profile P (NOLOCK) WHERE P.PrsnPIISSN_Chr IN ( SELECT '''' + REPLACE(CONVERT(VARCHAR(4000),txtFieldValue), ',', ''',''') + '''' FROM MassProcessing_Rules PR WHERE PR.intRuleID = 10 )
I have a column colC in a table myTable that has a value (e.g. '0X'). The position of a non-zero character in column colC refers to the ordinal position of another column in the table myTable (in the aforementioned example, colB).
To get a column name (i.e., colA or colB) from table myTable, I can join ("ON cte.pos = cn.ORDINAL_POSITION") to INFORMATION_SCHEMA.COLUMNS for that table catalog, schema and name. But I want to show the value of what is in that column (e.g., 'ABC'), not just the name. Hoping for:
COLUMN_NAME Value ----------- ----- colB 123 colA XYZ
I've tried dynamic SQL to no success, probably not executing the concept correctly...

Using SQL Server 2000. How can I refer to one alias in another column?E.g., (this a contrived example but you get the idea)SELECT time, distance, (distance / time) AS speed, (speed / time) AS acceleration FROM dataNote how the speed alias is used in the definition of acceleration alias but this doesn't seem to work.
use Northwind Go select dbo.Orders.OrderID ,Cast(dbo.Orders.OrderDate As DATE)Order_Date , dbo.Customers.CustomerID , dbo.Customers.CompanyName , dbo.Products.ProductName
[code].....
I cannot use the alias field names as part of additional calculations for new columns.
total_Amount and Grand_Total cannot be done with my skill level.
