Look Back Through Records To Apply Funds Appropriately
Dec 19, 2011
I have a table holding transaction data: money owed / money paid. The vast majority link together, however, a small % do not. I need to apply money paid to money owed. I want to give the client the benefit of the doubt, while using some logic in the application of funds.
I know when the transactions occurred, so I decided to work from newest to oldest, applying available funds from any money paid that is newer than the money owed. When the process completes the look back for an account, there may be money paid left over. This is okay, as it could apply to money owed transactions prior to the look back period.
I have code in place to accomplish this. My problem is the amount of time the process takes to run. At the current pace, it will take well over a day to complete. Here is an example of what the data may look like for one account:
Having issues with a table clearing out properly which is causing problems in the program.
By design there should only be one row in this table which updates with the most current record. However on this one system the table does not clear/update like it is supposed to, and instead starts adding multiple rows.
I have tried truncating the table but the problem does not resolve itself. Does anyone have any ideas as to why this might be happening?
create table a (id int, name varchar(10)); create table b(id int, sal int); insert into a values(1,'John'),(1,'ken'),(2,'paul'); insert into b values(1,400),(1,500);
select * from a cross apply( select max(sal) as sal from b where b.id = a.id)b;
Below is the result for the same:
idname sal 1John500 1ken500 2paulNULL
Now I'm not sure why the record with ID 2 is coming using CROSS APPLY, shouldn't it be avoided in case of CROSS APPLY and only displayed when using OUTER APPLY.
One thing that I noticed was that if you remove the Aggregate function MAX then the record with ID 2 is not shown in the output. I'm running this query on SQL Server 2012.
Hi... I'm reading the MS Press 70-442 Self-Paced Training kit, and I'm having problems with this example. I'd like help getting it to work correctly, or understand why it is isn't working the way I planned.
On page 67, the lab is about the APPLY operator (CROSS APPLY and OUTER APPLY). I first have to input a sample table-valued function into the AdventureWorks database:
Code Block CREATE FUNCTION fnGetAvgCost(@ProdID int) RETURNS @RetTable TABLE (AvgCost money) AS BEGIN WITH Product(stdcost) AS ( SELECT avg(standardcost) as AvgCost FROM Production.ProductCostHistory WHERE ProductID = @ProdID ) INSERT INTO @RetTable SELECT * FROM Product RETURN END
and then run a sample T-SQL statement
Code Block SELECT p.Name, p.ProductNumber, Convert(varchar, cost.AvgCost,1) AS 'Average Cost' FROM Production.Product p CROSS APPLY fnGetAvgCost(p.ProductID) AS cost WHERE cost.AvgCost IS NOT NULL ORDER BY cost.AvgCost desc
My problem is with the WHERE clause... According to page 56, CROSS APPLY returns only rows from the outer table that produces a result set, so why do I need to explicitly filter NULL values?
When I remove the WHERE clause, the query retrieves lots of NULL AvgCost values.
Again, according to page 56, it is the OUTER APPLY that returns all rows that return a result set and will include NULL values in the columns that are returned from the table-valued function.
So, in short, I don't see the difference between CROSS APPLY and OUTER APPLY, using this example, when I remove the WHERE clause?
(Please refrain from introducing another example into this question.)
I'm written a query to pull adjustments made on customer accounts, and I am attempting to pull in the payment associated with the adjustments. I'm using a single account to test my query and somewhere in my final output select statement I'm doing something that is bringing me back more records than I want. The code I have written is:
IF OBJECT_ID('TEMPDB..#TMP1O') IS NOT NULL DROP TABLE #TMP1O
I'm trying to insert records into "holding" table and write back identity column value (Entry_Key) to the original table. So my setup is I have two tables; tblEWPBulk and tbleFormsUploadEWP. Users will enter records into tblEWPBulk and use BatchID to group records, once batch entry has been completed (usually less than 30 records) user will click on UploadAll button and insert records (not all fields) into tbleFormsUploadEWP. One record in tblEWPBulk can be sent multiple times to the holding table but tblEWPBulk will need to have latest Entry_Key captured. Records are sent from holding table to DB2 z/VSE using SQL stored procedure and based on certain logic records are marked uploaded or certain error capture... that part works fine.
So for example I want to sendÂ
BatchID, AccountNumber, Period, ReceiveDate, AccountType, ReturnType, NetProfitOrLoss, TaxCredit FROM tblEWPBulk to the holding table and write back Entry_Key (identity column) back to the record in tblEWPBulk (field called UploadEntryKey). As I said one record could be sent to the holding table multiple times until uploaded or deleted and UploadEntryKey always needs to be updated so that when results are processed response from the DB2 can be inserted into table and presented to the user.
No foreign key relationship exists since records in the holding table get sent to the archive table and table is truncated and entry_key starting value reset back to 2000... just some DB2 restrictions.Â
I have a table with 1 million records. I want to update only 400 records. The update statement is provided by a 3rd party vendor. Once i run the update statement it will update all the 400 records. Once the table is updated the users will validate the table
if the update is successful or not. What i'm looking for is:
1) Is there a way to identify what records were updated. 2) If the update done is not what the users wanted i need to undo and bring back the 400 records to their previous values.
Hello,I'm trying to create a simple back up in the SQL Maintenance Plan that willmake a single back up copy of all database every night at 10 pm. I'd likethe previous nights file to be overwritten, so there will be only a singleback up file for each database (tape back up runs every night, so each daysback up will be saved on tape).Every night the maintenance plan makes a back up of all the databases to anew file with a datetime stamp, meaning the previous nights file stillexists. Even when I check "Remove files older than 22 hours" the previousnights file still exists. Is there any way to create a back up file withoutthe date time stamp so it overwrites the previous nights file?Thanks!Rick
New to Database Mirroring and I have a question about the Principal database server. I have a Database Mirroring setup configured for High-safety with automatic fail over mode using a witness.
When a fail over occurs because of a lost of communication between the principal and mirror, the mirror server takes on the roll of Principal. When communication is returned to the Principal server, at some point does the database that was the previous Principal database automatically go back to being the Principal server?

Hello,I am hoping you can help me with the following problem; I need to process the following steps every couple of hours in order to keep our Sql 2000 database a small as possible (the transaction log is 5x bigger than the db).1.back-up the entire database2.truncate the log3.shrink the log4.back-up once again.As you may have determined, I am relatively new to managing a sql server database and while I have found multiple articles online about the topics I need to accomplish, I cannot find any actual examples that explain where I input the coded used to accomplish the above-mentioned steps. I do understand the theory behind the steps I just do not know how to accomplish them!If you know of a well-documented tutorial, please point me in the right direction.Regards.
Does anybody know of a way to rollback SQL Server 2005 databases back to SQL Server 2000? Is there a way of doing it without resorting to Copy Database Wizard? I love to find a way of attaching a SS 2005 database to a SS 2000 instance without any issues.
I recently upgraded to SS 2005 and I am very unhappy with the SS 2005 and I want to rollback to SS 2000, which was a lot more stable. I am having several major issues that are affecting my whole company's day-to-day operations and the managers are not happy. Some of the issues include night time batch running very sluggish for no apparent reason. This is a biggest problem because it only occurs once or so a week and causes a disturbance with the daily activities when the night time processing isn€™t completed on time. The rest of the time, the batch processing runs great, even a little better then on SS 2000. I don't believe it is a matter of my application needing to be retuned because if that was the case, then why isn't it running sluggish every night? Also, it's never the same day that the sluggish behavior occurs. If it was occurring on the same night, then I would have something to investigate within our application, but it doesn't. Another issue that I am having involves a night time job that restores a copy of the production database to the Data Warehouse server to be used for updating the data warehouse. Again, most of the time it runs great (~2 1/2 hours), but once or twice a week, it goes stupid and takes 6 1/2 hours for no apparent reason. Again, it is not happening the same day either, which could give me something to invesigate. On SS 2000, this same job ran flawlessly. Never I did I run into situation that the database restoration took that long to run. Even another issue involves a SQL Server Agent Job that was put into suspended state. What's a suspended state and how can I get it out of suspended state? I can find no information about suspended state in BOL. I did a Google and nothing came up. If this suspended state was put in for security reasons, great, but then tell me how I can remove the suspended state. I am also not happy with the fact that I can't get accurate information about the queries that are actively running at that particular moment. In SS 2000, when I noticed high CPU usage on the server, I would run the sp_who2 active stored proc and it would show me all the active thread and how much CPU it was consuming. I would then find the running threads with the highest CPU numbers and investigate the query and see if we could improve it. Now in SS 2005, I get in the same situation and run the sp_who2 stored proc, and there is no smoking gun. All of the active threads are showing very little CPU usage, which I am very suspect of. What the heck happen to sp_who2? I looked at some of the other ways of looking at running processes (i.e... sys.sysprocesses) and they don't appear to be giving the information that I need.
I am very unhappy and I just want to roll back to SS 2000 and wait a couple of years before I upgrade to SS 2005.
writing the query for the following, I need to collapse the continuity. If the termdate for an ID is one day less than the effdate of the next id (for the same ID) i need to collapse the records. See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.
I am using SETROWCOUNT 10 in my stored procedure. At end of thi sp I use SETROWCOUNT 0. Will all other sp's that are executing at the same time as the above sp, get affected by the above SETROWCOUNT statement?
I have a table called Courses with columns "courseCode" "courseName" and "TeacherName"Im passing in a value @prefixText ...I have the following...Select courseModuleCode from courses Where courseModuleCode like @prefixTextwhat I actually want to do is return one list, i.e. one column that will do the same for "courseName" and "TeacherName" aswell based on what the @prefix tag is...so i will end up with one column that may contains some or all of the following courseModuleCode, courseName, TeacherName. Im basically implementing a search on this table and want the users to search by any of the column nameshope this makes sense.
I am new to DTS. In ExecuteSQLTask: want the original sql statement of <<backup database databaeABC to backup_databaseABC with init>> to be
backup database ? to 'backup_' + ? with init
But it looks the parameter could not place a globalVariable to it and parse it with error. One alternate way probably need to create a proc to pass a parm to it....
Also, how could pass a globalVariable to a FTP task?

SQL Server 2000 Original Release 8.00.194 RTM Database Components SP1 or Desktop Engine SP1 8.00.384 SP1 Database Components SP2 or Desktop Engine SP2 8.00.534 SP2 Database Components SP3 or SP3a, or Desktop Engine SP3 or SP3a 8.00.760 SP3
This would imply that after installing sp3a and restarting, the version reported should now be 8.00.760. However, it still shows 8.00.194. So it appears to have not really installed, althought the sp3a installation ran without incident. So, how can I get the sp3a to not just act like it installed, but actually get it to install? Also, I have shut down all mssql services and rebooted, applied patch, and rebooted again. Doesn't help. Also, if it is really installing, is there another way to tell?
Anyway, I really need to be able to install sp3a to see if it fixes another problem I'm having. Unfortunetly, since I can't even tell if the sp3a is installing, I can't tell if it really doesn't help or not. Thanks.
