SQL Server 2008 :: Aggregating Data From Common Table Expression
Apr 2, 2015
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,
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 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...

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,

I have an employee, who received an initial starting bonus of $50k.
This value will be static from day 1 to day n and will never change. I
want to see the intial starting bonus, but any sets higher than the
employee dimension will need to aggregate the starting bonus. Is there
an easy way to do this?
If I just look at the data from an employee's perspective, I can do
this by making the measure a Min, Max, or Avg Aggregate function. But,
if for instance I want to view the data from the perspective of
departments, it would need to sum() the data instead (which min/max/avg
don't do).
If I make the starting bonus a member property of the employee, and a calculated measure off the member property, it aggregates the data when it shouldn't.

)
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,

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:

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.

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?

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 am working to move an application from MySQL to SQL Server. The person who developed the MySQL application has little database experience, and took some shortcuts that the lax nature of MySQL allows. One query with which I am struggling looks something like this:
SELECT StartTime + Offset, min(Sensor), max(Sensor)
FROM SensorData
WHERE SensorID = @SensorID AND
StartTime + Offset > @BeginTime AND
StartTime + Offset < @EndTime
GROUP BY (StartTime + Offset) / 100
ORDER BY StartTime + Offset
What we are trying to accomplish is to return minimum and maximum sensor values over a number of periods between the BeginTime and EndTime. When I run this query in MySQL on a sample dataset, it returns a small number of rows, with each one being the min/max values for a portion of the overall period.
Under MS SQL Server 2008, SP3, I get the two following error messages:
Column 'SensorData.StartTime' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Column 'SensorData.Offset' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

ID (unique)Pm (the tblResourceAllocation.Owner's actual full name, which I'll look up from an EmployeeData table and concatenate the FirstName and LastName)IdClient (from tblResourceAllocation.Project I will look up the Customer from the Projects table, then look up the Customer ID from the Customers table)US_State_Id (look up State from Projects table then ID from tblStateCodes)Project_name (same as tblResourceAllocation.Project)Status (same as tblResourceAllocation.Status_FC)Id_operlst (same as tblResourceAllocation.ServiceID)Start (earliest start date of relevant entries)end (latest end date of relevant entries)Nb_ress (total number of ResourceAllocation entries that match Id_operlst)Cadence (explanation below)
I need to calculate how many of each serviceID's are in table 1, and then store that calculation and the ServiceID (Id_operlst) in table 2I need to separate those calculations by Owner, IdClient, US_State_Id, and Project_Name
I.E. If there are 5 entries in table 1 with ServiceId = X, and Owner A is listed on 2 of them and Owner B is listed on 3, I want it displayed as [Owner A, X, 2] and [Owner B, X, 3] in table 2.
Same goes for the other fields, which obviously adds more complexityWithin those calculations I also need to calculate the Start and end date for table 2. Using the last example, if one entry of Owner A's service X has the early start date and the other entry has the later end date, those dates need to be displayed in the Start and end for table 2 (should I use Rank here?)
I need to create a string of numbers separated by semicolons that shows how many resources are working on a given week after the start date
Example:I have 3 resources on a projectResource 1: 12/31/2012-1/27/2013 (Week 1-4 of our calendar)Resource 2: 1/7/2013-1/27/2013 (Week 2-4)Resource 3: 1/7/2013-1/27/2013 (Week 2-4)tblGRFM.Start will equal 12/31/2012 and tblGRFM.end will equal 1/27/2013Cadence should be equal to "1;3;3;3" to indicate that one resource will be working the project the first week, and three resources will be working the project for the next three weeks.

I'm trying to create a query to return Open, Close, Max and Min Price for each 1 minute interval. Source data has two fields - Price, and Datestamp at 5 second intervals.
I can calculate the Max and Min (below) and set the datestamp to the middle of the interval, but get stuck on how to also return the Open and Close price for each interval.
SELECT MAX(price) AS MaxPrice, MIN(price) AS MinPrice,
DATEADD(ss, 30, DATEADD(n,DATEDIFF n, '1/1/2006', DateStamp),'1/1/2006')) AS DateStamp
FROM MasterData
GROUP BY DATEDIFF(n, '1/1/2006',DateStamp)
Any ideas?
thanks in advance.

I am developing the SSIS and stuck on copying specific files.
1. We receive CSV file to our drive on a daily basis.
2. The csv file name has the last 8 digits formatted with the yyyymmdd. For example, the file name might be abcdef_20150226.csv This means it will be our CSV file for today, Thursday, February 26, 2015.
3. There are a lot of files in this directory.
[URL]
What we would like to do:
Add the constraints (or expression) that will copy the files from this directory to another directory that have the date equivalent to Monday only. For example, the file abcdef_20150226.csv will not be copied because it is Thursday file. But the abcdec_20150223 will be copied to a new Directory because it is Monday.

MyTable has the following data (Just a sample)
parent | NAme | Checked | contactmethod|Check2 | Other
974198 | Employment | true | Face to Face | true | null
974224 | Other | true | Face to Face | true | skills
974224 | Other | true | Contact | true | skills
I'd like to pivot on "parent"
In a perfect world I'd like to see output like
974198 | Employment | true | Face to Face | true | null
974224 | Other | true | Face to Face, Collateral Contact | true | skills
If there are more than one name or contactmethod for the same parent then they would be strung along with commas

I need to update the Denominator column in one row with the value from the Numerator column in a different row. For example the last row in the table is
c010A92NULL
I need to update the Denominator, which is currently NULL, with the value from the Numerator where the MeasureID=c001 and GroupID=A.
This value is 668 so, the row should look like
c010A92668
create table dbo.TEST
(
MeasureID varchar(10),
GroupID char(1),
Numerator float,
Denominator float
)
[Code] .....

I have a XML data passed on to the stored proc in the following format, and within the stored proc I am accessing the data of xml using the nodes() method
Here is an example of what i am doing
DECLARE @Participants XML
SET @Participants = '<ArrayOfEmployees xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Employees EmpID="1" EmpName="abcd" />
<Employees EmpID="2" EmpName="efgh" />
</ArrayOfEmployees >'
SELECT Participants.Node.value('@EmpID', 'INT') AS EmployeeID,
Participants.Node.value('@EmpName', 'VARCHAR(50)') AS EmployeeName
FROM
@Participants.nodes('/ArrayOfEmployees /Employees ') Participants (Node)
the above query produces the following result
EmployeeID EmployeeName
--------------- -----------
1 abcd
2 efgh
How do I join the data coming out from the above query with another table in the database, for example Employee in this case
i.e. somewhat like this (note the following query does not perform the join correctly)
SELECT Participants.Node.value('@EmpID', 'INT') AS EmployeeID,
Participants.Node.value('@EmpName', 'VARCHAR(50)') AS EmployeeName
FROM
@Participants.nodes('/ArrayOfEmployees /Employees ') Participants (Node)
INNER JOIN
Employee EMP ON EmployeeID = EMP .EmployeeID
My desired output after the join would be
EmployeeID EmployeeName Email Home Address
--------------- ----------- --------------- -----------
1 abcd abcd@abcd.com New York
2 efgh efgh@efgh.com Austin

I want to bulk insert data into a table named scd_event_tab inside a database named rdb.
When I do select * from rdb.dbo.scd_event_tab, i get :
JOB_ID RUN_ONPRIORITYPAYLOADTIMEOUT_INTERVALSTATUSPICKUP_TIMESCD_TYPESCHEDULE_IDDB_ADMIN_LOGIN_REQUIRED_YN
I saved the result into a csv file and then truncated the table. Now, I am trying to bulk insert the data into the table. So I used:
bulk insert
rdb.dbo.scd_event_tab from 'C:userssluintel.ctrdesktopeventtab.csv'
with
(
codepage = 'RAW',
datafiletype = 'native',
fieldterminator = ' ',
keepidentity,
keepnulls
);
go
However, I get this error:
Msg 4867, Level 16, State 1, Line 1
Bulk load data conversion error (overflow) for row 1, column 1 (JOB_ID).
Msg 4866, Level 16, State 5, Line 1
The bulk load failed. The column is too long in the data file for row 1, column 3. Verify that the field terminator and row terminator are specified correctly.
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.
Msg 7330, Level 16, State 2, Line 1
Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".

I have a query needs to look for 5 records data in a table. Basically i need to hardcode. Below is my query which didn't work out.
select BF_ORGN_CD, BF_BDOB_CD, BF_TM_PERD_CD,data
from BF_DATA
WHERE (BF_ORGN_CD,BF_BDOB_CD,BF_TM_PERD_CD) in ***** i guess this is the wrong query****
('A1', 'B1', 'C1')
('A2', 'B2', 'C2')
('A3', 'B3', 'C3')
('A4', 'B4', 'C4')
('A5', 'B5', 'C5')
but if i use the query below it will generate more records than these 5 records
select BF_ORGN_CD, BF_BDOB_CD, BF_TM_PERD_CD,data
from BF_DATA
WHERE (BF_ORGN_CD) in ('A1', 'A2', 'A3', 'A4', 'A5')
and (BF_BDOB_CD) in ('B1', 'B2', 'B3', 'B4', 'B5')
and (BF_TM_PERD_CD) in ('C1', 'C2', 'C3', 'C4', 'C5')

I want to create a XML file with data in my table. I have a question about tags.
SELECT
-- Root element attributes
'http://tempuri.org/Form.xsd' AS 'xmlns',
'http://www.w3.org/2001/XMLSchema-instance' AS 'xmlns:xsd',
(
SELECT
-- Creating a default element
[Code] ....
This is my query. When I use 'xmlns' namespace the result is below:
<Form xmlns="http://tempuri.org/Form.xsd" xmlns:xsd="http://www.w3.org/2001/XMLSchema-instance">
<Veri xmlns="">
<Satir>
<Id>1</Id>
</Satir>
</Veri>
</Form>
I dont want to see 'xmlns' in 'Veri' tag. When I use xmlna or another word instead of 'xmlns' the result is below:
<Form xmlns="http://tempuri.org/Form.xsd" xmlna:xsd="http://www.w3.org/2001/XMLSchema-instance">
<Veri>
<Satir>
<Id>1</Id>
</Satir>
</Veri>
</Form>
How can I remove 'xmlns' from 'Veri' tag while using it in 'Form' tag

I have the following two tables:
CREATE TABLE [MailBox].[Message](
[Id] [bigint] IDENTITY(1,1) NOT NULL,
[SenderId] [bigint] NOT NULL,
[Message] [nvarchar](max) NOT NULL,
[SentDate] [datetime] NOT NULL,
CONSTRAINT [PK_MailBox.Message] PRIMARY KEY CLUSTERED
[Code] ....
I'm building a messaging functionality in to my application, I'm able to insert a message into the database and this message then appears inside the other users inbox. The issue I have it when I click on this message to view the conversation I make a call to the following sp as shown here:
@UserId bigint,
@SenderId bigint
AS
BEGIN
SET NOCOUNT ON;
[Code] .....
The problem with this is I'm trying to connect to the user photos table to return their profile picture, but for some reason even though I have specified IsProfilePic I get all the photos returned, instead it should be two photos, one for the @UserId and the other for the @SenderId, its equivalent to me doing this:
Select *
From [User].[User_Photos]
where (UserId = 1 or UserId = 2) and IsProfilePic = 1
And this returns me the correct information.
