How To Compare The Previous Row With Current Row In SQL Server 2000
Nov 10, 2005
Hi,
I have to compare the previous row with current row in a table in SQL Server 2000. Please help me how to do this in a optimized way. Table contains nearly 30 columns and rows count is more than 10 digits.
My current code returns account_number with multiple start_date regardless of the value is same or not. However, I would like to get only the account number when the value on start_date is different within same account_number.
select acct_number count(start_date) from table_A group by acct_number, start_date having(count(start_date) > 1)
There are two tables testmaster and testdetail. If the value of Price for a particular ID in testdetail is more than the threshold value defined in testmaster, the output should have a new column with value as 'High Value', if the value is less than the threshold the new output should be 'Low Value' other wise 'Ignore'
Example: for ID=3, threshold is defined as 40% in testmaster table, but on 11/12/2015 the new price is 100 which 100% more than the previous value, so the status is High Value as shown below.
ID Date Price Status 1 11/12/2015 100 Low Value
2 11/12/2015 160 Ignore 3 11/12/2015 100 High Value
create table testmaster ( ID int, Threshold int ) create table testdetail ( ID int, Date varchar(20), Price float )
HiI want to write a function that can return a sum for a given daterange. The same function should be able to return the sum for the sameperiod year before.Let me give an example:The Table LedgerTrans consist among other of the follwing fieldsAccountNum (Varchar)TransdateAmountMST (Real)The sample data could be1111, 01-01-2005, 100 USD1111, 18-01-2005, 125 USD1111, 15-03-2005, 50 USD1111,27-06-2005, 500 USD1111,02-01-2006, 250 USD1111,23-02-2006,12 USDIf the current day is 16. march 2006 I would like to have a functionwhich called twice could retrive the values.Previus period (for TransDate >= 01-01-2005 AND TransDate <=16-03-2005) = 275 USDCurrent period (for TransDate >= 01-01-2006 AND TransDate <=16-03-2006) = 262 USDThe function should be called with the AccountNum and current date(GetDate() ?) and f.ex. 0 or 1 for this year / previous year.How can I create a function that dynamically can do this ?I have tried f.ex. calling the function with@ThisYear as GetDate()SET @DateStart = datepart(d,0) + '-' + datepart(m,0) +'-'+datepart(y,@ThisYear)But the value for @dateStart is something like 12-07-1905 so thisdon't work.I Would appreciate any help on this.BR / Jan
I need help writing a query that will subtract the values of 2 rows from the same column to display in the result set. Some background information: a table has a sales column that keeps track of sales by the minute, but this is done in a cumulative manner, i.e, sales at row 3(minute 3) = sales recorded @ minute 2 plus sales @ minute 3. Therefor to get the actual sale at min 3, i would have subtract value at row 2 from row 3. make sense? it sounds very easy but I am having a hard time refering back to the previous row and am dealing with more than 1000 rows. i thought about doing a self join on the table but could not get it to do what i want. would appreciate any help i can get. thanks
I am trying to create a stored procedure where i would like to fetch the next previous and current rows from a particular pagename which is stored in a table with sorting of dateadded
like my products table structure
id iQty strProductTitle strPageName DtAdded DtApproved
I am novice to intermediate writer of T-SQL. Here is my current Query:
SELECT [FISCALYEAR], [ACCTPERIOD], SUM([ACTIVITYDEBIT]) AS TrialBalanceDebit, [POSTINGTYPE] FROM [dbo].[TB_Lookup] WHERE [POSTINGTYPE]='Profit & Loss' GROUP BY [FISCALYEAR],[ACCTPERIOD], [POSTINGTYPE] ORDER BY acctperiod ASCand this is what is produces.
FISCALYEARACCTPERIODTrialBalanceDebitPOSTINGTYPE 2014 201401 282361372.13000 Profit & Loss 2014 201402 227246272.86000 Profit & Loss 2014 201403 315489534.33000 Profit & Loss 2014 201404 287423793.76150 Profit & Loss 2014 201405 256521290.76000 Profit & Loss 2014 201406 65582951.30000 Profit & Loss
Now I need a way to add another field that takes the TrialBalanceDebit from current ACCTPERIOD and adds it to the Previous ACCTPERIOD TrialBalanceDebit.
I've tried all sorts of code i.e. cross apply, running totals, etc. Cannot get this to work. I am trying to add a previous row value but only doing it for each group.
I would like to set the start time of the next row to be equal to the previous row time + duration. I know the start time of each group of 'Items' when the 'Sequence' number = 1. The last 'duration' value in the group would be ignored.
Now i want to compare Result and dislay prevterm where student fail:
Now my output would be as: Now I want to compare latest term i.e. Term5 with prev Terms and if found Mismatch in result then i want to display as below:
I need to return the previous row value if it is negative in current row. For example, in the below table for ID=7 i need the value 1305(ID=4) since 6,5 are negative values.Â
Existing  values
          ID       Input           ID      Input
I am looking to pull all records for current & previous calendar year in one query. I know how to pull the current calendar year, but how would I pull current & previous?
I have a table with score info for each group, and the table also contains historical data, I need to get the ranking for the current week and previous week, here is what I did and the result is apparently wrong:
select CurRank = row_number() OVER (ORDER BY cr.CurScore desc) , cr.group_name,cr.CurScore , lastWeek.PreRank, lastWeek.group_name,lastWeek.PreScore from (select group_name, Avg(case when datediff(day, asAtDate, getdate()) <= 7 then sumscore else 0 end) as CurScore
[Code] ....
The query consists two parts: from current week and previous week respectively. Each part returns correct result, the final merged result is wrong.
I am using one datetime data type ( name: date_added ) and getdate() as default value. I want to display only those records added today. How I can compare current date with date_added.
Hi all, I have encountered a problem that I can't compare the date in SQL Server 2000. But I know that maybe I have used "datetime" as data type for that field. My question is that, how can I get ONLY the "date" in stead of "datetime" from the database? Your attention is appreciated! Thank you.
Our business get orders through the week with the weekends (Fri & Sat) orders being higher than weekdays. Im wanting to graph this years data with last years and possible the years before but to compare days in such a way that the all the weekdays line up. so comparing 2015 week 1 with 2014 week 1 but with 03/01/2015 (Sat) lining up with 04/01/2014 (Sat) etc.
I'm looking for alternatives to adding or removing days from the dates to solve this issue, i have a date dimension table for the past 5 years that i can use to compare calendar week 201401 with calendar week 201501 but I am finding it a bit inflexable.
We are trying to compare our current calendar week (based on Monday being the first day of the week) with the previous calendar week.Â
I'm trying to produce a line chart with 2 axis:
- x axis; the day of the week (Mon, Tues, Wed etc - it is fine for this to be a # rather than text e.g. 1 = Mon, 2 = Tues etc) - y axis; the cumulative number of ordersÂ
The chart needs two series:
Previous Week. The running count of orders placed that week. Current Week. The running count of orders placed this week.Â
Obviously in such a chart the 'Current Week' series is going not going to have values along the whole axis until the end of the week. This is expected and the aim of the chart is to see the current week compares against the previous week for the same day.Â
I have two tables:
Orders TableCalendar Table
The calendar table's main date column is [calDate] and there are columns for the usual [calWeekNum], [calMonth] etc.Â
My measure for counting orders is simply; # Orders: = countrows[orders].
How do I take this measure and then work out my two series. I have tried numerous things such as adapting TOTALMTD(), following articles such as these:
-Â [URL] ... -Â [URL] ...
But I have had no luck. The standard cumulative formulas do work e.g. if I wanted a MTD or YTD table I would be ok, it's just adjusting to a WTD that is causing me big issues.
I am in the middle of taking course 2073B €“ Programming a Microsoft SQL Server 2000 Database. I noticed that in Module9: Implementing User-Defined Functions exercise 2, page 25; step 2 is not returning the correct answer.
Select employeeid,name,title,mgremployeeid from dbo.fn_findreports(2)
It returns manager id for both 2 and 5 and I think it should just return the results only for manager id 2. The query results for step 1 is correct but not for step 2.
Somewhere in the code I think it should compare the inemployeeid with the previous inemployeeid, and then add a counter. If the two inemployeeid are not the same then reset the counter. Then maybe add an if statement or a case statement. Can you help with the logic? Thanks!
Here is the code of the function in the book:

In Transact SQL I need to calculate the difference between the current bottom and the previous top. If there is no previous top, then the result would be the current bottom.
So, the result would be 0, 2, 2.5, 1
I must return the value in a table. Thank you all for your help!

Does abyone know how to compare data-type xml in a temp/variable/physical table in MSSQL 2000?
I tried this works in MSSQL 2005,
Code Snippet create Table #t1 ([c1] int identity(1,1) not null, [c2] text) create Table #t2 ([c1] int identity(1,1) not null, [c2] text) Insert into #t1 Values('This is a test') Insert into #t2 Values('This is a test') Select * from #t1 Select * from #t2 Select * from #t1 where [c2] LIKE (Select [c2] from #t2) drop table #t1 drop table #t2
but not MSSQL 2000.
Server: Msg 279, Level 16, State 3, Line 12 The text, ntext, and image data types are invalid in this subquery or aggregate expression.
Is this true (from BOL)?
Code SnippetIn comparing these column values, if any of the columns to be compared are of type text, ntext, or image, FOR XML assumes that values are different (although they may be the same because Microsoft® SQL Server„¢ 2000 does not support comparing large objects); and elements are added to the result for each row selected.
