Common Need: History Table

Jan 22, 2008

Hi there!

I'm working on an application designed like this:
There's a table "DailyTransations" (DT) containing daily transactions...
Then there's an archive table "TransationsArchive" (TA) with the exact same structure.

When a record is inserted in DT, it is also in TA (via a trigger) and the reporting is done against TA.
Now for performance issues, we delete from DT the records older than 2 days since they are not needed for processing.

First, what do you think of that implementation?

We thought about using partitions based on the transaction date and completely eliminate TA, but it seems once a record is assigned to a partition, it is not moved automatically...

What is the common solution for this need?

Thanks
Frantz

Creating A Common Table Expression--temporary Table--using TSQL???

Jul 23, 2005

Using SQL against a DB2 table the 'with' key word is used todynamically create a temporary table with an SQL statement that isretained for the duration of that SQL statement.What is the equivalent to the SQL 'with' using TSQL? If there is notone, what is the TSQL solution to creating a temporary table that isassociated with an SQL statement? Examples would be appreciated.Thank you!!

I have managed to write my first CTE SQL that handles recursion but I have a problem with distinct - can't get that to work!!
My CTE:WITH StudentsHierarchy(SystemID1, GroupID, AccessType, AccessGroupID, StudentID, HierarchyLevel) AS
(
--Base Case
SELECT
SystemID,
GroupID,
AccessType,
AccessGroupID,
StudentID,

UNION ALL

--Recursive step
SELECT
u.SystemID,
u.GroupID,
u.AccessType,
u.AccessGroupID,
u.StudentID,
uh.HierarchyLevel + 1 as HierarchyLevel
FROM UserGroup u
INNER JOIN StudentsHierarchy uh ON
u.GroupID = uh.AccessGroupID

)
Select sh.SystemID1, sh.GroupID, sh.AccessType, sh.AccessGroupID, sh.StudentID, sh.HierarchyLevel, (select StudentName from Student s
where sh.StudentID = s.StudentID) AS StudentName from StudentsHierarchy sh
WHERE AccessType = 'S'
 
and I would like to have a distinct on the StudentID like:Select DISTINCT sh.StudentID, sh.SystemID1, sh.GroupID, sh.AccessType, sh.AccessGroupID, sh.StudentID, sh.HierarchyLevel, (select StudentName from Student s

Index On Used Table Common Fields

Jan 6, 2012

I would like to know if SQL Server creates automatic index on the used tables' common fields.

For example:

Code:
CREATE VIEW [dbo].[ORMAN]
AS
SELECT dbo.PARSEL.OBJECTID, dbo.PARSEL.ADAPARSEL, dbo.PARSEL.ORMANADI, dbo.PARSEL.MULKIYET, dbo.PARSEL.ALAN, dbo.PARSEL.YERKOD,
dbo.PARSEL.UYG_KAN, dbo.PARSEL.KomNo, dbo.PARSEL.KadKan, dbo.PARSEL.Mescere, dbo.PARSEL.ACIKLAMA, dbo.PARSEL.URETIM_YONTEMI,

[Code] .....

On the above view example, if table PARSEL has 1 million records do I have to create an index for PARSELDURUM or when I create a view does SQL server create automatic virtual index?

Join A Table With Different Tables But With A Field In Common?

Jan 27, 2014

I have a table activity which show the activities of the site. An activity could be related with no other entity or it could be related with an account, or with a contact or with an opportunity. An opportunity and a contact could be also related with an account.

My problem is that I need to show the activity and the related account (if there is any) but because the relationship with an account could be done by different ways, I dont know how to do it without join the account table several times.

This is my current query:

SELECT AC.IdActividad, CU.idcuenta
FROM Actividades AC LEFT JOIN Tareas TA ON TA.IdActividad = C.IdActividad
LEFT JOIN ActividadesXCuenta AXC ON AC.IdActividad = AXC.IdActividad LEFT JOIN dbo.Cuentas CU ON axc.IdCuenta = CU.IdCuenta
LEFT JOIN dbo.ActividadesXOportunidad axo ON AC.IdActividad = axo.IdActividad LEFT JOIN dbo.Oportunidades o ON axo.IdOportunidad = o.IdOportunidad LEFT JOIN dbo.Cuentas CU1 ON o.IdCuenta = CU.IdCuenta
LEFT JOIN dbo.ActividadesXContacto axco ON AC.IdActividad = axco.IdActividad LEFT JOIN dbo.Contactos con ON axco.IdContacto = con.IdContacto LEFT JOIN dbo.Cuentas CU2 ON o.IdCuenta = CU.IdCuenta

As you see, I have the table Cuenta joined 3 times. That means that I need to put the ActivityID field 3 times but based on how the report was developed, I could not do that.

Writing ETL Error Records To A Common Table

Jun 13, 2007

I am working on building a template/design pattern for a DTS to SSIS upgrade project.



During our ETL processing, if we encounter a record that cannot be inserted into a destination table, we'd like to be able to write the entire record out to a common error/reject table. The obvious problem is that every SSIS package that is using this template will of course be dealing with varying table schemas.



I was thinking that if there were a way that I could transform the error record/buffer row into XML, I could then achieve my goal of having a common table to receive errors/rejects.



Has anyone done something like this, or have suggestions on how we might accomplish?

Multiple Operations On A Common Table Expression

Jan 28, 2008

Hi,
I'd like to perform a number of different operations on my Common Table expression but I seem to be limited to only one operation. For example I cannot both delete duplicate rows and then perform a select statement. I can only execute one of the statements referencing the common table expression.

What is wrong with my syntax?


;With OrderedTable

AS

(

select Row_number() OVER (partition BY SSNumber order by Department_Id desc ) AS ROWID,* from Employee

)

delete from OrderedTable where RowId != 1

SELECT COUNT(*),SSNumber FROM OrderedTable group by Department_Id order by count(*) desc

Conditional Processing From A Common Table Expression (CTE)

Sep 5, 2007

I want to do conditional processing depending on values in the rows of a CTE. For example, is the following kind of thing possible with a CTE?:


WITH Orders_CTE (TerritoryId, ContactId)
AS
(
SELECT TerritoryId, ContactId
FROM Sales.SalesOrderHeader
WHERE (ContactId < 200)
)
IF Orders_CTE.TerritoryId > 3
BEGIN
/* Do some processing here */
END
ELSE
BEGIN
/* Do something else here */
END

When I try this, I get a syntax error near the keyword 'IF'

Any ideas? I know this kind of thing can be done with a cursor but wanted to keep with the times and avoid using one!

Is WITH / Common Table Expression A Syntactic Sugar?

Oct 4, 2006

I tried to use WITH to factor out the shared star join portion from a sql statement as it's usually the most expensive part.

However, examing the execution plan shows that the WITH clause is merely a syntactic suger that will internally be plugged back as derived tables where the same star join is executed repeatedly.

Is the intermediate rowset produced by a WITH caluse ever shared during the query execution?

SQL Server 2005 Common Table Expression(CTE) Implement Reg.

Aug 30, 2006

Hi,

We are developing the web application using ASP.NET 2.0 using C# with Backend of SQL Server 2005.

Now we have one requirement with my client, Already our application live in ASP using MS Access Database. In Access Database our client already wrote the query, those query call the another query from same database. So I want to over take this functionality in SQL Server 2005.

In ASP Application, We call this query €œ081Stats€? from Record set.

This €˜081Stats€™ query call below sub query itself

Master Query: 081Stats

SELECT DISTINCTROW [08Applicants].school, [08Applicants].Applicants, [08Interviewed].Interviewed, [Interviewed]/[Applicants] AS [interviewed%], [08Accepted].Accepted, [Accepted]/[Applicants] AS [Accepted%], [08Dinged].Dinged, [Dinged]/[Applicants] AS [Dinged%], [08Waitlisted].Waitlisted, [Applicants]-[Accepted]-[Dinged] AS Alive, [08Matriculating].Matriculating, [Matriculating]/[Accepted] AS [Yield%]
FROM ((((08Applicants LEFT JOIN 08Interviewed ON [08Applicants].school = [08Interviewed].school) LEFT JOIN 08Accepted ON [08Applicants].school = [08Accepted].school) LEFT JOIN 08Dinged ON [08Applicants].school = [08Dinged].school) LEFT JOIN 08Waitlisted ON [08Applicants].school = [08Waitlisted].school) LEFT JOIN 08Matriculating ON [08Applicants].school = [08Matriculating].school;

Sub Query 1: 08Accepted

SELECT statusTbl.school, Count(1) AS Accepted
FROM statusTbl
WHERE (((statusTbl.decision)=1) AND ((statusTbl.yearapp)="2008"))
GROUP BY statusTbl.school
ORDER BY Count(1) DESC;

Sub Query 2: 08Applicants

SELECT statusTbl.school, Count(1) AS Accepted
FROM statusTbl
WHERE (((statusTbl.decision)=1) AND ((statusTbl.yearapp)="2008"))
GROUP BY statusTbl.school
ORDER BY Count(1) DESC;

Sub Query 3: 08Dinged

SELECT statusTbl.school, Count(1) AS Dinged
FROM statusTbl
WHERE (((statusTbl.decision)=0) AND ((statusTbl.yearapp)="2008"))
GROUP BY statusTbl.school
ORDER BY Count(1) DESC;

Sub Query 4: 08Interviewed

SELECT statusTbl.school, Count(1) AS Interviewed
FROM statusTbl
WHERE (((statusTbl.interview)=True) AND ((statusTbl.yearapp)="2008"))
GROUP BY statusTbl.school
ORDER BY Count(1) DESC;

Sub Query 5: 08Matriculating

SELECT statusTbl.school, Count(1) AS Matriculating
FROM statusTbl
WHERE (((statusTbl.userdec)=True) AND ((statusTbl.yearapp)="2008"))
GROUP BY statusTbl.school
ORDER BY Count(1) DESC;

So now I got the solution from SQL Server 2005. I.e. Common Table Expressions, So I got the syntax and other functionality, Now my doubts is how do implement the CTE in SQL Server 2005, where can I store the CTE in SQL Server 2005.

How can I call that CTE from ASP.NET 2.0 using C#?

CTE is replacing the Stored Procedure and Views, because it is memory based object in SQL Server 2005.

How can I implement the CTE, where can I write the CTE and where can I store the CTE.

And how can I call the CTE from ASP.NET 2.0 using C#.

It€™s Very Urgent Requirements.

We need your timely help.

With Thanks & Regards,
Sundar

Common Table Expression Calling Stored Procedure

Nov 19, 2007

Hi,

I have a stored procedure that return 0 or 1 row and 10 columns. In my subsequent queries I only need 1 column from those 10 columns. Is there any better way other than creating or declaring temp table and than making a select from that table.

So I am looking int CTE to execute stored procedure and than make a selection from CTE, but CTE does not allow me to execute stored procedure. Is there any other better way of acheiving this.

This is what I want to change:

Declare @Col Varchar(10)
Decalre @TempTable(Col1 Int, Col2 Varchar(10), Col3 Varchar(10), Col4 Varchar(10))

Insert into @TempTable
Exec Procedure @Paramter

select @Col = col2 from @TempTable

INTO

With CTE(Col2, Col3, Col4) AS
(

Exec Procedure @Paramter)

select @Col = col2 from @TempTable

Thanks

Microsoft OLE DB Provider For IBM DB2 Does Not Accept Common Table Expressions

Oct 26, 2007



After reading all the comments about microsoft ole db provider for db2, I've started converting a project from ibm db2 provider to microsoft ole db provider, for the reason that the server would not need a ibm client software installation anylonger.
However in one of the dataflows there is a select statement on the DB2 database (AS400 iseries DB2 V5R4) that uses common table expression. The Oledb data source in the Dataflow returns zero input columns when I use the microsoft provider instead of the ibm provider. When I set it back to use the ibm oledb provider the input columns are available again.
The common table expression is used in the select statement like:
WITH x AS (SELECT ... FROM mytable WHERE ...)
SELECT x.*, (x.a - x.b) As diff
FROM x

We are not allowed to change anything in the DB2 database, so using views or sprocs is not an option.

Did anyone else experience this and can it be avoided without changing the selct logic?

Grouping By Month In Common Table Expression Counts Wrong

Sep 26, 2012

I'm using CTEs to try and get the totals of two different criteria queries that I want to group by Month depending on the associated Inquiry Date. Here is what I have right now;

Code:
;With CTE(total, InitDate) as
(
SELECT count(Inquiry.ID), Inquiry.Date from Inquiry
Inner Join Inquirer on Inquirer.ID = Inquiry.InquirerID_fk
Left Join Transfer on Transfer.TransferInquiryID_fk = Inquiry.ID
WHERE (Inquiry.Date >= '3/1/2012' AND Inquiry.Date <= '9/26/2012' AND Inquiry.Date IS NOT NULL)
AND (Inquirer.Program = 'Res. Referral Coord.')AND TransferInquiryID_fk IS NULL
Group By Inquiry.Date

[code]...

I get 170 for InitCount, but for TransCount I only get 19, not 26. I assume it is with my left outer join statement grouping but I am not sure how I would change this to get the proper counts. All I want to do is group the values together depending on the month they were done in.

SQL Server 2008 :: Aggregating Data From Common Table Expression

********QUERY BEGIN*****************

DECLARE @EndDate datetime
SET @BeginDate = '2014-01-01'
SET @EndDate = '2014-12-31';

WITH CTE AS (
SELECT bkg_nbr

[Code] ....

The raw data from the CTE is:

Bkg_nbr STATE_NBR Ranking
20140000943200060000 1
20140000131500140000 1
20140000682200140000 2
20140000504100210000 1

The result of the query above was:

Category RecCount
Non-Recidivists3
Recidivists 1

The outcome I was looking for was:

Category RecCount
Non-Recidivists2
Recidivists 1

What I am trying to do is count persons in buckets "non-recidivists" and "recidevists" based on how many bkg_nbr they have per STATE_NBR. If they have more than 1 bkg_nbr per STATE_NBR then put them in the "recdivists" bucket. If they only have a 1 to 1 then put them in the "non-recidivists" bucket.

SQL Server 2012 :: Filtering Common Table Expression Within View

Sep 1, 2015

I have a multi-tenant database where each row and each table has a 'TenantId' column. I have created a view which has joins on a CTE. The issue I'm having is that entity framework will do a SELECT * FROM MyView WHERE TenantId = 50 to limit the result set to the correct tenant. However it does not limit the CTE to the same TenantId so that result set is massive and makes my view extremely slow. In the included example you can see with the commented line what I need to filter on in the CTE but I am not sure how to get the sql plan executor to understand this or weather it's even possible.I have included a simplified view definition to demonstrate the issue...

ALTER VIEW MyView
AS
WITH ContactCTE AS(
SELECT Col1,
Col2,

Preferred Method To Incorporate Common Table Expression (CTE) Functionality

Feb 26, 2007

What is the best approach to utilize a recursive CTE (Common Table Expression) to filter a resultset?  The CTE function is used in all application queries to limit recursively the final resultset based on a provided hierarchical organization identifier. i.e. join from some point in the organization chart on down based on an organization id. I would prefer that the query could be run real-time. i.e. not having to persist the prediction portion of the results to a sql relational table and  then limiting the persisted results based on the CTE function. 

It appears that I can use a linked server to access the prediction queries directly from SQL Server (link below). I believe that I might also be able to deploy a CTE recursive function within a .net assembly to the Analysis Server but I doubt that recursive functionality is availalble without a linked SQL Server.

Is It Possible To Execute The T-Sql Code Of Common Table Expressions In VB 2005 Express?

Jan 2, 2008

Hi all,
I have the following T-SQL code of Common Table Express (CTE) that works in the SQL Server Management Studio Express (SSMSE):

--CTE.sql--

USE ChemAveRpd

GO

WITH PivotedLabTests AS

(

SELECT LT.AnalyteName, LT.Unit,

Prim = MIN(CASE S.SampleType WHEN 'Primary' THEN LT.Result END),

Dupl = MIN(CASE S.SampleType WHEN 'Duplicate' THEN LT.Result END),

QA = MIN(CASE S.SampleType WHEN 'QA' THEN LT.Result END)

FROM LabTests LT

JOIN Samples S ON LT.SampleID = S.SampleID

GROUP BY LT.AnalyteName, LT.Unit

)

SELECT AnalyteName, Unit, avg1 = (abs(Prim + Dupl)) / 2,

avg2 = (abs(Prim + QA)) / 2,

avg3 = (abs(Dupl + QA)) / 2,

RPD1 = (abs(Prim - Dupl) / abs(Prim + Dupl)) * 2,

RPD2 = (abs(Prim - QA) / abs(Prim + QA)) * 2,

RPD3 = (abs(Dupl - QA) / abs(Dupl + QA)) * 2

FROM PivotedLabTests

GO

===========================================
How can I execute this set of the CTE.sql code in the VB 2005 Express via the Stored Procedure programming?

Please help and respond.

Thanks in advance,
Scott Chang

Transact SQL :: How To Apply Foreign Keys On Top Of A Common Lookup Table

Apr 29, 2015

I have an issue where i am mandated to enforce RI on an applications database (a good thing). but I have several common lookup tables where many of the "codes" reside for many different code types. I also have the mandate that i cannot change the underlying DDL to make composite keys to match the codes table PK. I am currently looking at creating indexed views on top of the Codes table to seperate the logical tables it contains. This is several hundred views.

I do know that I do not want to write several hundred triggers to enforce RI. Table schema below, the CdValue column is the column that is used throughout the hundreds of tables that use this codes table, and their corresponding column is not named the same.

CREATE TABLE dbo.CodesTable (
PartyGrpId INT  NOT NULL
  , CdTyp  VARCHAR ( 8 ) NOT NULL
  , CompId INT  NOT NULL
  , CdValue VARCHAR ( 8 ) NOT NULL
  , CdValueDesc VARCHAR ( 255 ) NULL
  , AltValueDesc VARCHAR ( 100 ) NULL

[Code] ....

I did though run into one forum where a person brought up a great idea. Filtered Foreign Keys, what a novel concept, if it could work it would make so much less code to fix an issue like this.

ALTER TABLE dbo.BusinessStatus WITH NOCHECK
ADD CONSTRAINT FK_dbo_BusinessStatus_CodesTable FOREIGN KEY (LoanStsDtCd) REFERENCES dbo.CodesTable (CdValue) WHERE CdTyp = 'Status'

Instances And History In One Table

Jan 11, 2008

I have a database design question. There're lots of ways to rome they say, and I want to hear what you think of this way.

Government supplies wheel chairs (and thinks alike) to people who need them. They stay in possesion of the (local) government and are distrubuted by a company X.

So we have Tools (Wheelchairs) and Users (of wheel chairs). The life-cycle of a wheel chair is that more than one user while use it over time.

I want to keep track of which users used a instance of a wheelchair.

No there's a developer who likes to put this in one table. (the chair and it's user) in a way like this


UID, WheelChairId, UserId, OwnerId, SerialNumber, BeginDateTime, EndDateTime, SomeOtherColumns

The UID is unique, the WheelChairId is a GUID which is Unique per wheelchair, but can have mutliple records in the table with no overlap.

If one of the values of the columns is changed a new record is made with the same wheelchair and a new begin date (the closed record gets an Enddate). So history is made automaticaly. By using the right query's I can see what users uses the chair in what period of time. But also changed ownerships and other changes in Someother columns overtime.

Is this a good or a common practice? Why use it, or stay away from it?

Speed/efficiency Of View Vs. Common/nested Table Expression In A Join

Mar 2, 2008



i have been trying to determine which is the most efficient, with regards to speed and efficiency, between a view and a common/nested table expression when used in a join.

i have a query which could be represented as index view or a common table expression, which will then be used to join against another table.

the indexed view will use indexes when performing the join. is there a way to make the common table expression faster than an indexed view?

How To Design The History Table To Be More Efficient?

Feb 8, 2007

I am running a website of crossword puzzle and Sudoku games. The website is designed to be:
There are 20-30 games onlines each day.
Every registered user could play and submit the game to win scores.
For each game, every registered user could get the score for ONLY one time. i.e., No score will be calculated if the user had finished the game before.
To avoid wasting time on a game finished before, user will be notified with hint message in the page when enter a already finished game.


The current solution is:
3 tables are designed for the functions mentioned above.
Table A: UserTable --storing usering information, userid
Table B: GameList --storing all the game information.
Related fields:
GameID primary key
FinshiedTimes recording how many times the game has been finished
Table C: FinishHistory --storing who and when finished the game
Related fields:
GameID ID of the game
UserID ID of the user
FinishedDate the time when the game was finshied

PS: Fields listed above are only related ones, not the complete structure.

Each time when user enters the game, the program will read Table B(GameList), listing all the available game and the times games have been finished. User could then choose a desired game to play.

When user clicks the link and enter a page showing the detail content of the game, the program will read Table C(FinishHistory) to check whether user has finished this game before. If yes, hint message will be shown in the page.

When user finishes the game and submit, the program will again read Table C(FinishHistory) to check whether user has finished this game before. If yes, hint message will be shown in the page. If no, user will get the score.

Existing Problems:
With the increase of game and users, the capacity of Table C(FinishHistory) grows rapidly. And each time when a game is loaded, the Table C will be loaded to check, and when a game is submitted, the Table C will be loaded to check again. So it is only a time question to find out Table C to become a bottleneck.

Does any one here have any good suggestions to change / re-invent a new structure or design to avoid this bottleneck?
