SQL Server Sorting Criteria
May 14, 2007
Hi All,
I've read aroud the following tecqnique to parameterize the sort criteria of a stored procedure:
PROCEDURE [ParamSortProc_EXAMPLE]
...
@SortField VARCHAR(64)
AS
BEGIN
SET NOCOUNT ON
-- ....
IF @SortField NOT IN ('Field1', 'Field2', 'Field3', 'Field4')
BEGIN
SET @SortField = 'Field1' -- Default
END
SELECT
-- ...
FROM
-- ...
WHERE
-- ...
ORDER BY
CASE @SortField WHEN 'Field1' THEN T.Field1 END ASC,
CASE @SortField WHEN 'Field2' THEN T.Field2 END ASC,
CASE @SortField WHEN 'Field3' THEN T.Field3 END DESC,
CASE @SortField WHEN 'Field4' THEN T.Field4 END DESC
The point is: the sort field is choosed based on the actual value of @SortField.
Provided the source table T has specific indexes for all the 4 fields involved into the sorting operation, does the engine actually benefit from it or, instead, treat the 4 sort conditions as computed fields and so build a temporary index to face with it?
Thanx a lot for your reply.

For example, consider the following queries:
DECLARE @SomeParam INT
SET @SomeParam = 44
SELECT *
FROM TableA A
JOIN TableB B ON A.PrimaryKeyID = B.ForeignKeyID
WHERE B.SomeParamColumn = @SomeParam
SELECT *
FROM TableA A
JOIN TableB B ON A.PrimaryKeyID = B.ForeignKeyID AND B.SomeParamColumn = @SomeParam
Both of these queries return the same result set, but the first query filters the results in the WHERE clause whereas the the second query filters the results in the JOIN criteria. Once upon a time a DBA told me that I should always use the syntax of the first query (WHERE clause). Is there any truth to this, and if so, why?
Thanks.

I have a report where I am giving the users a parameter so that they can select which field they would like to sort on.The report is also grouping by that field. I have a gruping section, where i have added code to group on the field I want based on this parameter, however I also would like to changing the sorting order but I checked around and I did not find any info.
So here is my example. I am showing sales order info.The user can sort and group by SalesPerson or Customer. Right now, I have code on my dataset to sort by SalesPerson Code and Order No.So far the grouping workds, however the sorting does not.
Any suggestions would help.
Thanks

SSRS 2012 - VS2010...The report compares two years with a sort order on a value that has been engineered based on text switched to int. When sorting A-Z this is the result in the horizontal axis is: 5th, K, 1st, 2nd, 3rd, 4th, 5th..When sorting Z-A the result in the horizontal axis is:5th, 4th, 3rd, 2nd, 1st, PreK..Z-A is correct but A-Z sorting shows 5th as the start and end. The magnitude of the PreK location is correct but the label is wrong on the A-Z sort order. The sorting is implemented using the Category Group sorting option.

I am stuck with a query that I am working on. I have data like below.
DECLARE @Input TABLE
(
OrderID INT,
AccountID INT,
StatusID INT,
Value INT
)
INSERT INTO @Input VALUES (1,1,1,15), (2,1,1,20), (3,2,1,5), (4,2,2,40), (5,3,1,20), (6,1,2,40), (7,1,2,40)
If an Account's value reaches 20 for StatusID = 1 and 40 for StatusID = 2, that is a called "Good". I want to find out which order made the Account become "Good".
By looking at the data, it is understandble that AccountID 1 crossed Status ID 1's limit of 20 with order 2, but the status ID 2's limit was only crossed after the 6th order was placed. So my output should show 6 for AccountID 1.
For AccountID 2, value of statusID 1 was 5 with orderid 3, but it reached the limit for status id 2 of 40 with order 4. But the first condition was not met. so it shouldn't be seen in the output.
Same with AccountID 3 as well, It reached the limit of status id 1 with order 5 but the limit for order 2 wasn't reached so it should be ignored as well.
I wrote the code as below, its working fine but I still know there are better ways to write since I will be working with atleast a million records.
;WITH CTE AS
(
SELECT OrderID,AccountID, StatusID, SUM(Value) OVER(Partition By AccountID, StatusID ORDER BY OrderID) AS RunningTotal
FROM @Input
[Code] ....

Getting a weird error while trying out a query from Access 2003 on aSQL Server 2005 table.Want to compute the amount of leave taken by an emp during the year.Since an emp might be off for half a day (forenoon or afternoon), havethe following computed field:SessionOff: ([ForenoonFlag] And [AfternoonFlag])The query works fine when there's no criterion on SessionOff.However, when I try to get the records where the SessionOff equals 0, Iget the following error:~~~~~ODBC--call failed.

Hello All,
I was hoping that someone had some wise words of wisdom/experience on this. Any assistance appreciated... feel free to direct me to a more efficient way... but I'd prefer to keep using a stored proc.
I'm trying to pass the selected value of a dropdownlist as a stored procedure parameter but keep running into format conversion errors but I am able to test the query successfully in the SQLDatasource. What I would like to do is this: select * from tblPerson where lastnames Like "A%" . Where I pass the criteria after Like. I have the values of the drop down list as "%", "A%", "B%", ....
I've been successfully configuring all of the other params, which includes another dropdown list (values bound to a lookup table also)... but am stuck on the above...
Thank you for any assistance,

I have a data output with many rows. In order to group things with flags, I do this in excel using 2 formulas which *** a flag of 0 or 1 in 2 new columns.
This takes a long long time as I have hundreds of thousands of rows and wondered of I could do it in sql?
Its transact SQL and the formulas I use in excel are:
=IF(SUMPRODUCT(($A$2:$A2=A2)*($B$2:$B2=B2)*($C$2:$C2>=C2-1/24)*($C$2:$C2< C2+1/24))> 1,0,1)
=IF(SUMPRODUCT(($A$2:$A2=A2)*($B$2:$B2=B2))>1,0,1)
How I can do this in sql??
The columns above do not relate to the actual columns I use, just an example.

I have a dataset where i want to select the records that matches my input values. But i only want to try macthing a field in my dataset aginst the input value, if the dataset value is not NULL.
I always submit all 4 input values.
@Tyreid, @CarId,@RegionId,@CarAgeGroup
So for the first record in the dataset i get a succesfull output if my input values matches RegionId and CarAgeGroup.
I cant figure out how to create the SQl script for this SELECT?
My dataset

Say I want to search for a range of account numbers but only which are active. After I set my field for A (active) this field shows in my results, I dont want it to.
In Access you can easily just uncheck that field in design view, but how do I do it in sql?

I am trying to import data from 4 columns in a spreadsheet, the Columns are (Last Name - First Name - ID - Code) and this spreadsheet has around 10k records. I want to add what is in this spreadsheet to the query I have below that uses the EXCEPT operator but I am not sure the best way to go about it.
Using the example I have filtered below for the name "Denise Test", at the end of the day I want everything that is in the spreadsheet to also be excluded from the results.
So before the spreadsheet lets say the 2nd query referencing table C has the following results for Denise Test
Last_Name First_Name ID Code
Test Denise 1 5
Test Denise 2 4
After adding the spreadsheet I want it to show this:
Last_Name First_Name ID Code
Test Denise 1 5
Test Denise 2 4
Test Denise 3 3
Here is the query as it stands now without the inclusion of the spreadsheet:
SELECT
ta.last_name,
ta.first_name,
tb.ID,
tb.code
FROM
TableA ta
INNER JOIN TableB tb
[code]....

I have a string filed which holds ID's such as:
1, 1.1, 1.2, 1.1.1, 1.1.2
I need to run a query to sort these by ID such as the result should be: 1, 1.1, 1.1.1, 1.1.2, 1.2
There could be infinite levels ie. 1.1.1.1.1, i'm baffled by this at the mo as i can't cast it to say a float and then sort because of the muliple points. Any ideas would be great. Looking for mimumum overhead here, would like to do it on the SQL Server side
Thanks.

Ok, it is a given that sorting operations are sometimes expensive in SQL Server using the ORDER BY clause because the relational model is not really well suited to sort data blah blah blah.
So the canned DBA response is "this is a presentation issue, handle it in the presentation layer".
OK, great. Problem solved. So I am digging around in the ADO.Net object model trying to give a junior developer some guidance and i am trying to figure out what is the best way in ADO.Net to order what we used to call a recordset where the sorting is not done at the SQL Server, but in IIS.
I imagine there is some overhead in this operation as well. Is it really going to save me some overall performance or am I just shifting the burden and I will not likely see any appreciable difference?

I need to calculate the last two columns (noofgrp and grpsize) No of Groups (count of Clientid) and Group Size (number of clients in each group) according to begtim and endtime. So I tried the following in the first Temp table
GrpSize= count(clientid) over (partition by begtime,endtime) else 0 end
and in the second Temp Table, I have
select
,GrpSize=sum(grpsize)
,NoofGrp=count(distinct grpsize)
From Temp1
The issue is for the date of 5/26, the begtime and endtime are not consistent. in Grp1 (group 1) all clients starts the session at 1030 and ends at 1200 (90 minutes session) except one who starts at 11 and end at 1200 (row 8). For this client since his/her endtime is the same as others, I want that client to be in the first group(Grp1). Reverse is true for the second group (Grp2). All clients begtime is 12:30 and endtime is 1400 but clientid=2 (row 9) who begtime =1230 but endtime = 1300. However, since this client begtime is the same as the rest, I wan that client to be in the second group (grp2) My partition over creates 4 groups rather than two.

The database has approx. 2500 temporary tables. The temp tables match a pattern such as APTMP... I tried deleting the tables in SSMS with the statement, Delete from Information_Schema.tables where substring(table_name,1,5) = 'APTMP' This returns the error message"Ad hoc updates to system catalogs are not allowed".
What is the correct way to delete a group of tables whose name match a pattern from within SSMS?

I have a table
GO
CREATE TABLE [dbo].[Speech] ( [SpeechId] [int] IDENTITY(1,1) NOT NULL CONSTRAINT PkSpeech_SpeechId PRIMARY KEY, [UniqueName] [varchar](52) NOT NULL, [NativeName] [nvarchar](52) NOT NULL, [Place] [nvarchar](52) NOT NULL, [Type] [smallint] NOT NULL, [LanguageId] [char](2) NOT NULL CONSTRAINT FkSpeech_LanguageId FOREIGN KEY (LanguageId) REFERENCES Language(LanguageId) ON UPDATE CASCADE ON DELETE CASCADE, [SpeakerId] [int] NOT NULL CONSTRAINT FkSpeech_SpeakerId FOREIGN KEY (SpeakerId) REFERENCES Speaker(SpeakerId) ON DELETE CASCADE, [IsFavorite] [bit] NOT NULL, [IsVisible] [bit] NOT NULL, [CreatedDate] [datetime] NOT NULL DEFAULT GETDATE(), [ModifiedDate] [datetime] NULL )
Now I want to search the Table Speech
Sometimes by : SpeechIdSometimes by : SpeakerIdSometimes by : LanguageIdSometimes by : SpeechId And LanguageIdSometimes by : SpeakerId And LanguageId
All can have conditions with IsVisible, IsFavorite and Type columns.
for example
I need all Speeches withany particular SpeakerId and LanguageIdwith IsVisible equals to trueand IsFvaorite No Matterand Type equals to Audio
For these type of queries I think the solution is
GO
CREATE PROCEDURE [dbo].[sprocGetSpeech]
@speechId int = NULL, @uniqueName varchar(52) = NULL, @nativeName nvarchar(52) = NULL, @place nvarchar(52) = NULL, @type smallint = NULL, @languageId char(2) = NULL, @speakerId int = NULL, @isFavorite bit = NULL, @isVisible bit = NULL
AS
SELECT SpeechId, UniqueName, NativeName, Place, Type, LanguageId, SpeakerId, IsFavorite, IsVisible, CreatedDate, ModifiedDate FROM Speech WHERE SpeechId = @speechId AND UniqueName = CASE WHEN @uniqueName IS NULL THEN [UniqueName] ELSE @uniqueName END AND NativeName = CASE WHEN @nativeName IS NULL THEN [NativeName] ELSE @NativeName END AND Place = CASE WHEN @place IS NULL THEN [Place] ELSE @place END AND Type = CASE WHEN @type IS NULL THEN [Type] ELSE @type END AND LanguageId = CASE WHEN @languageId IS NULL THEN [LanguageId] ELSE @languageId END AND SpeakerId = CASE WHEN @speakerId IS NULL THEN [SpeakerId] ELSE @speakerId END AND IsFavorite = CASE WHEN @isFavorite IS NULL THEN [IsFavorite] ELSE @isFavorite END AND IsVisible = CASE WHEN @isVisible IS NULL THEN [IsVisible] ELSE @isVisible END
Can anyone tell me?
Is it right way to do?Do you have any better solution?If my solution is better then Is there any performance loss with that query?

I am familiar and happy with using BCP to export from SQL Server to a flat file
.. 1) Is there any way to pass a parameter to the sql script file each time so that i can vary the selection critria the script file uses each time?
.. 2) Can i batch the BCP calls together so they all use this parameter with some kind of 'super' BCP cammand?
Thanks in anticipation

200404 40 30

200406 60 50
200407 70 60
i wanted to generate an OUTPUT in the following format :
The output of the query should look like this :
reporting_date interest_payment balance
Q1 -2004 60 10
Q2 -2004 170 30
Q3 -2004 70 60
Q4 -2004 0 0
i.e i wanted to represent data by quarter and year and group by quarter and year for interest_payment column but for balance i need to pick up the value from the first reporting date in that quarter ,so as you can see q1-2004 has 10,15 and 20 but only 10 is accounted as that was the first reporting date in that quarter
I have my query working for interest payment but i am not sure how do i pickup the first reporting value for balance in a quarter
SELECT report_year as "@date",'Q'+CAST(report_quarter+1 as varchar(1)) as "@quarter", SUM(a.balance) as "@balance", SUM(a.interest_payment) as "@interest_payment"
FROM (SELECT *,
(reporting_date%100 - 1)/3 as report_quarter,
reporting_date/100 as report_year
FROM employee) a
GROUP by report_year, report_quarter

use of Row_Number() over ( partition... but I dont understand how.
Imagine I have a table like
CustomerID, PartNum, QtyinOrder, shipped
1 6 3 0
1 6 2 0
2 6 1 0
2 5 1 0
2 5 2 0
2 5 3 0
2 5 4 1
1 6 4 1
2 6 2 1
But I wanted to return
CustomerID, PartNum, MaxQtyOrderedNotShipped
That would be just the rows
1 6 3 0
2 6 1 0
2 5 3 0
If I use this:
Select CustomerId,PartNum, shipped, QtyInOrder AS MaxOrderedNotShipped
from
(SELECT [CustomerID]
,[PartNum]
,[QtyInOrder]
,shipped
, row_number() over (partition by [CustomerID], PartNum order by QtyInOrder desc) as recid from [SILK].[dbo].[MaxofGroup]) as f where recid =1
there is no restriction, so I get the shipped...If I alter the where clause to work only on not shipped, I get no records...as below
Select CustomerId,PartNum, shipped, QtyInOrder AS MaxOrderedNotShipped
from
(SELECT [CustomerID]
,[PartNum]
,[QtyInOrder]
,shipped
, row_number() over (partition by [CustomerID], PartNum order by QtyInOrder desc) as recid from [SILK].[dbo].[MaxofGroup]) as f where recid =1 and shipped=0

Hi,
While playing with SQL Server 2000 I found you can specify the selection criteria in either the FROM clause or the WHERE clause:
e.g.
select *
from Table1 a inner join Table2 b ON a.key = b.key and a.field = 1
Is logically the same as:
select *
from Table1 a inner join Table2 b ON a.key = b.key
where a.a = 1
Any comments on which is best, and why?
Thanks,
Chris

I have a query that searches through a 4 million record table. The data is fed from the UNIX flat file systems so the data is not in optimal search format. So I created some views that massaged the data and then index them. I select and join the original table with the view, with NOEXPAND hint on the view. My question is this theory right: If I put the criteria in the FROM join part then it will make the join easier than if I put it in the where clause?
Example (any difference)
SELECT stuff1, stuff2 FROM UglyData u INNER JOIN MassageTable m ON m.RecNumber LIKE '112%' AND u.ID = m.ID
versus
SELECT stuff1, stuff2 FROM UglyData u INNER JOIN MassageTable m ON u.ID = m.ID WHERE m.RecNumber LIKE '112%'
THANKS!!!

I am creating a .aspx page that links with Miscrosoft SQL Server 2005 Express. It includes a GridView control that displays all the table data on the page. You can then select a record from the control (currently by clicking an image button to the left of each record- is there any way of selecting the record by clicking anywhere on the row? How would that be done?) and it displays the data in a detailsview control below where the data can be changed etc.
The data is like a phonebook (Name, Telephone number, and some other misc fields) and the user should be able to search by either name or number to filter out the records shown in the gridview control. I have two textboxes for this, and I started with the name text box and it works fine. i.e. with one filterparameter and one filterexpression. So that if you just enter 'Da' it filters out the records displaying only those whose name starts with 'Da'.
I have experimented but have found no way of including filter expressions to use the number as a search. I added the second filter parameter (under sqldatasource control so that:
<FilterParameters>
<asp:ControlParameter Name="DestinationName" ControlID="txtName" /><asp:ControlParameter Name="DestinationNumber" ControlID="txtNumber" />
</FilterParameters>
But I don't know what to do for the FilterExpressions. currently I just have:
FilterExpression="DestinationName LIKE '{0}%'"
i have tried using "DestinationName LIKE '{0}%' OR DestinationNumber LIKE '{0}%'" but it requires that both text boxes have data entered.
What I want is something that allows the user to enter either a name or number or both (all or part of so don't need to enter in full name/number) and it filters out the records accordingly. I.e. if you enterd 'Dav' and '079' it would bring back all the records who had a name starting with Dav and a number starting with 079. However if you enterd just 079 then it should just bring back all records with numbers starting 079 whatever their associated name.
Thanks

I have a text box that is used to submit stock symbols that are to be saved in a sql table. The symbols are to be separated by a space or a comma (I don't know which, yet). I want to retrieve the symbols later to be used in a query, but I don't know how to get the symbols in the proper string format for the query, eg
The symbols are stored in the tables as: A B C D
The query string criteria would look like: IN('A', 'B', 'C', 'D')
The IN('A', 'B', 'C', 'D') citeria would be the values in the @Symbol variable in this SPROC
SELECT a_Name_Symbol.Symbol, a_Financials.Revenue
FROM a_Financials INNER JOIN
a_Name_Symbol ON a_Financials.Symbol = a_Name_Symbol.Symbol
WHERE (a_Name_Symbol.Symbol @Symbol)
ORDER BY a_Name_Symbol.Symbol
Is there a slick (ie easy) way to change the contents entered in the text box (A B C D) into IN('A', 'B', 'C', 'D') ?
Thanks,
Paul

I need a little insight on how to select the same field from the same table, but for different criteria.
here are example tables...
Categories
CATSUBCATNAME
10MainTitle
11SubTitle #1
12SubTitle #2
20Section
21Section #1
DataTable
CATSUBCATINFO
11Detail Information for subtitle #1
12Detail information for subtitle #2
desired result would be:
MainTitle, SubTitle #1, Detail Information for subtitle #1
MainTitle, SubTitle #2, Detail Information for subtitle #2
Select c1.Name, c2.Name, d.info
from DataTable d, Categories c1, Categories c2
where c1.CAT = d.CAT
and c2.CAT = d.CAT
and c2.SUBCAT = d.SUBCAT

I have a database with some over normalized tables in it. The best I can do with one query is get the file ID. In the second query I want to get all the file names, based on all the fileID's I got from the first query. How would I go about doing this?
