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,
TenantId
[code]....

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?

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

I am trying to create a small data set for use in a charting program. However, I am not getting the results that I expected.
********QUERY BEGIN*****************
DECLARE @BeginDate datetime
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.

Hi all,
I ran the following CTE sql code:
Use ChemDatabase
GO
WITH PivotedTestResults AS
(
SELECT TR.AnalyteName, TR.Unit,
Prim = MIN(CASE S.SampleType WHEN 'Primary' THEN TR.Result END),
Dupl = MIN(CASE S.SampleType WHEN 'Duplicate' THEN TR.Result END),
QA = MIN(CASE S.SampleType WHEN 'QA' THEN TR.Result END)
FROM TestResults TR
JOIN Samples S ON TR.SampleID = S.SampleID
GROUP BY TR.AnalyteName, TR.Unit
)
SELECT AnalyteName, UnitForConc,
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,
RPD2 = abs(Dupl - QA) / abs(Dupl + QA) * 2
FROM PivotedTestResults
GO
//////////////////////////////////////////////////////////////////////////////////////
I got the following errors:
Msg 207, Level 16, State 1, Line 9
Invalid column name 'Unit'.
Msg 207, Level 16, State 1, Line 3
Invalid column name 'Unit'.
////////////////////////////////////////////////////////////////////////////////////////////////////////////////
I guess that I had "Unit" (instead of "UnitForConc"), when I executed the sql code last time!!!???
How can I delete the old, wrong CTE that is already in the ChemDatabase of my SSMSE?
Please help and advise.
Thanks in advance,

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

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!

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?

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!!

Hi guys,
I'm trying to have two common table expression in my stored procedure, but I'm receiving errors when executing it, I found that they can't exist side by side,once I removed 1 of them, the stored procedure executed successfully.
The following are the errors
Code:
Msg 156, Level 15, State 1, Procedure GetProductsByCategory, Line 27
Incorrect syntax near the keyword 'With'.
Msg 319, Level 15, State 1, Procedure GetProductsByCategory, Line 27
Incorrect syntax near the keyword 'with'. If this statement is a common table expression or an xmlnamespaces clause, the previous statement must be terminated with a semicolon.

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

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.

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.

Hey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.

I've inherited a table of members that has the following structure:
CREATE TABLE [dbo].[dimMember](
[dimMemberId] [int] IDENTITY(1,1) NOT NULL,
[dimSourceSystemId] [int] NOT NULL CONSTRAINT [DF_dimMember_dimSourceSystemId] DEFAULT ((-1)),
[MemberCode] [nvarchar](50) NOT NULL,
[FirstName] [nvarchar](250) NOT NULL,
[LastName] [nvarchar](250) NOT NULL,
[Code] ....
Based on the way the data loads into the table there's a possibility of some records being near duplicates of each other. For example, we can have a member that has records that have the same first name, last name, SSN, but different addresses, membercodes, subscribercode etc... This can happen in pretty much any variation thereof.
What I want to do, is add a new column and use that to group the similar records under based on comparing on several columns. By this I mean, if a member matches 4 of the 7 values below with another member, we would group these:
First Name (1st 3 characters)
Last Name
DOB
CurrentAddress1
MemberCode
SSN
SubscriberCode
I'm at a loss of how to structure the SQL to update the new column in the table.

I have a report which contains a parameter called SuppressZero which depending on its value I want to filter out certain data. This parameter can have 3 different values and for each value I need to have a different filter expression. What I would like to do is implement the following:
If SuppressZero = 1
Filter where Quantity <> 0
If SuppressZero = 2
No Filter
If SuppressZero = 3
Filter where Quantity <> 0 Or InStockFamily = "Y"
How can I do this in my report?

CREATE TABLE [Table 2] (
Id varchar,
MoreData varchar )
What is the link between these two tables?
I have databases that have zero keys defined, no foreign key constraints, no unique value constraints. I cannot assume that an Identity column is the Id. The end game is be able to output that [Table 1].[TableTwoId] = [Table 2].[Id] but cannot assume that all linkage in the database will be as simple as saying "if the field name contains a table name + Id then it is the Id in that table."
Currently have written a script that will cycle through all columns and start identifying keys in singular tables based on the distinctness of the values in each column (i.e. Column1 is 99% distinct so is the unique value). It will also combine columns if the linkage is the combination of one or more columns from Table 1 = the same number of columns in Table 2. This takes a long time, and it somewhat unreliable as IDENTITY columns may seem to relate to one another when they don't.

How I am using a CASE statement within a WHERE clause to filter data:
CREATE PROCEDURE dbo.GetSomeStuff
@filter1 varchar(100) = '',
@filter2 varchar(100) = ''
AS
BEGIN
SELECT
[Code] .
What I want, is to be able to pass in a single value to filter the table, or if I pass in (at the moment a blank) for no filter to be applied to the table.
Is this a good way to accomplish that, or is there a better way? Also, down the line I'm probably going to want to have multiple filter items for a single filter, what would be the best way to implement that?

I am completely new to SQL and I am trying to filter a table on one column to build a view. The column is 5 characters. For most of the records only the first three characters are present the last two are spaces. I would like to search for the first three characters but include records that contain the last two characters. I am looking for 001, 006, 061, 064, 070, and 227.
[RD_ID] nvarchar length 5
I have tried ‘001’ or ‘001 ‘ or ‘001*’
Thanks for any help.

I am using BETWEEN '02/01/2007' AND '2/01/2006' in the criteria of a VIEW and have tried <= '02/01/2007' AND >='2/01/2006' but both are not filtering the dates correctly. Is there another way? What am I missing?

I have created a variable in a SQL Task and assigned it to a string variable. When I debug the container with a breakpoint, I can see the correct date value being assigned to the variable.
I have an ADO Net source setup to an Oracle connection. I need to pull the Oracle data down that has an updated date greater than the updated date in my ODS.
My issue is that the variable is not being passed through to my expression that I use for an ADO Net source.
"SELECT * FROM BI_EDW.GL_JE_HEADERS WHERE LAST_UPDATE_DATE > To_Date('" + (DT_WSTR, 19) @[User::varLastUpdateDate] + "','yyyy-mm-dd hh24:mi:ss')"

We have a LKP table that we will use to decode incoming codes from multiple sales feeds to link to the relevant surrogate key for the ultimate dimension table.
The LKP table has a start date, end date and active row flag to track history of the codes.
This table in its entirety is required for the FULL history load but we will need a CURRENT version of the table containing only the ACTIVE rows for the DAILY incremental loading.
I am thinking of putting a standard view over the top of the LKP table to present only the ACTIVE rows rather than creating a 2nd table and reloading it each night. We don't have enterprise edition to use materialised views.
My question is, will the LKP cache populate as the SSIS packages begins, loading it with all the rows from the view, as it would if I used the 2nd physical table with only ACTIVE rows?

I have a simple SP that returns 2 columns with 4 inner joins, results are about 100 odd rows max, nothing complicated. When I run the SP via SSMS it works fine, as soon as this is run via an application server the SP fails to complete with the error :
Internal error: An expression services limit has been reached. Please look for potentially complex expressions in your query, and try to simplify them.
We are not getting anywhere near the expression limit so I cannot understand why we are suddenly receiving this error. 2 weeks ago this query was running fine, no updates have been rolled out to the SQL database servers or application servers but the error is suddenly appearing on both prod and dev environments.
