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'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. Msg 319, Level 15, State 1, Procedure GetProductsByCategory, Line 33 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.
I was studying Common Table expression in Sql server 2005. I have written the code Declare @PictureArray as varchar(200) Set @PictureArray = ''; with UserProfile_CTE(UserPicture) As( select @PictureArray = @PictureArray + '~' + PictureName from UserPicture where UserProfileID = 1102 select @PictureArray ) select * from UserProfile_CTE
But I am getting the error Incorrect syntax near '=' I am getting the error in the lineselect @PictureArray = @PictureArray + '~' + PictureName from UserPicture where UserProfileID = 1102 But I don't know the reason for this, Kindly advice Regards Karan
What is the SQL Server equivalent of DB2 common table expressions? Forexample,with gry(year,count) as(select floor(sem/10),count(distinct ssn)from gradesgroup by floor(sem/10))select year,sum(count) Head_Count from grygroup by yearhaving year >= 1980;N. ShamsundarUniversity of Houston
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!!
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#.
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.
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 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.
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
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.

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?
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?
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.
I want to run multiple DTS packages which export data into text files. There is only one Data Source ..and multiple destinations. When i write a code for this in VB ,for each Package i need to define the source connectioninividually. Can't i use the same Source connection which i used for the first package in the subsequent packages?
Information for configuring Service Broker when you have multiple initiators seems to be thin on the ground. The examples are all point-to-point and seem to require separate logins for each initiator and corresponding exchange of certificates using a multi-pass installation. E.g. Rushi's ServiceListing API.
We have an application with several hundred workstations which need to send transaction data to department servers and then on to corporate. There is also a need to replicate small amounts of reference data to all levels.
The examples seem to generate an installation and administrative nightmare.
I have a question - would the following scheme work?
1. All our machines are on the same domain so transport security can be handled by Windows Security (One less set of certificates to exchange).
2. Generate 2 Certificates on the Corporate database and export them to the department and workstations use these pre-installed certificates in each database to handle dialog security for all converations. Ie. multiple workstations feed into one user id on the department server using a single certificate. Ditto for all the department servers feeding into corporate.
3. Use Service broker id's to determine where messages are sent (as the same services would be installed at multiple locations).
4. When a database is intalled/restored at a workstation does this invalidate any certificates that are shipped with it?
I know there is some kind of rule against the following SQL statement, but I was wondering what to do to get around this problem (some kind of grouping). Sorry for the stupid question.
SELECT * FROM Table1, Table2 WHERE Table1.ID IS NOT NULL AND Table2.ID IS NOT NULL
Basically I want to select all records from the two tables (they have the same fields, but are just different specialties) and then output them, but there is nothing in common between the two to reference one another, and it ends up in some kind of loop. Thanks. for the help.
Here is my situation. I am building a report that has three different tables each with their own dataset. Example: Opportunities, Leads, Activities. All three of these datasets/tables have a common field - SalesID. I would like the report to show the first SalesID, then all Opportunities for that SalesID in the Opportunities table, followed by all Leads for that SalesID in the Leads table, followed by all Activities for that SalesID in the Activities table, and then rollover to the next SalesID and repeat that for all SalesIDs. Any suggestions on how I could achieve this? Thanks in advance for all help!!!
Hi i have always used views in my code to group common functionality in my sql expressions and then i can simply call these views in my data access layer by saing: SqlCommand cmd = new SqlCommand("SELECT * FROM vw_Documents WHERE CategoryID = @CategoryID", cn); However my view has become so complicated that i had to convert it to a stored procedure called sp_Documents. The problem now though is that is that i wish to do queries against the data returned but i can't simply say: SqlCommand cmd = new SqlCommand("SELECT * FROM sp_Documents WHERE CategoryID = @CategoryID", cn); The only way i can see to do it is to create a stored procedure for every single senario i have passing in the appropriate values as parameters. This seems a pretty messy solution to me because i would have repeated logic in all my stored procedures. Therefore i was wondering if there's a simpler way for me to do this or am i just being lazy :). Appreciate if someone could help,
I have a sql query that I am using to populate a datagrid. The problem is one of the tables is a month table. and the other tables are full of data. So there is no common column name to match using a inner join "on".
I'm using Reporting Services Integration Mode and I have a page that has a number of report viewer webparts on it to display reports. Is there a way that I can add another webpart to pass parameters to all the reports at once instead of individually? I am trying to build a dashboard and this is one of the requirements. I see on the Report Viewer web part, that there is an option in Connections to 'Get report parameters from' , but it is greyed out. Any ideas on how to do this?
Hi there. Does anyone know of a why to perform several operations on a table within only 1 ALTER TABLE statement? I haven't found anything to date and don't even know if it's possible.
Hellow Folks. Here is the Original Data in my single SQL 2005 Table: Department: Sells: 1 Meat 1 Rice 1 Orange 2 Orange 2 Apple 3 Pears The Data I would like read separated by Semi-colon: Department: Sells: 1 Meat;Rice;Orange 2 Orange;Apple 3 Pears I would like to read my data via SP or VStudio 2005 Page . Any help will be appreciated. Thanks..
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...
