Sorting Views
Jul 18, 2005
Hiya,
I'm back with another question.
I have a view of a table which contains users. the SQL is:
CREATE VIEW dbo.vwTravellers
AS
SELECT TravellerID AS ID, LTRIM(RTRIM(LastName)) + ', ' + LTRIM(RTRIM(FirstName)) + ' - DOB:' + LEFT(RTRIM(DOB), 11) AS Value
FROM dbo.tblTravellers
I would like to be able to sort the view by LastName, Firstname, but it doesnt allow a SORT BY in the view. Does anyone know of a cheeky little trick I could use to get around this?
Cheers
Guy
I wish I'd listened in that SQl Server training course I attended :(

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.

Fellow database developers,I would like to draw on your experience with views. I have a databasethat includes many views. Sometimes, views contains other views, andthose views in turn may contain views. In fact, I have some views inmy database that are a product of nested views of up to 6 levels deep!The reason we did this was.1. Object-oriented in nature. Makes it easy to work with them.2. Changing an underlying view (adding new fields, removing etc),automatically the higher up views inherit this new information. Thismake maintenance very easy.3. These nested views are only ever used for the reporting side of ourapplication, not for the day-to-day database use by the application.We use Crystal Reports and Crystal is smart enough (can't believe Ijust said that about Crystal) to only pull back the fields that arebeing accessed by the report. In other words, Crystal will issue aSelect field1, field2, field3 from ReportingView Where .... eventhough "ReportingView" contains a long list of fields.Problems I can see.1. Parent views generally use "Select * From childview". This meansthat we have to execute a "sp_refreshview" command against all viewswhenever child views are altered.2. Parent views return a lot of information that isn't necessarilyused.3. Makes it harder to track down exactly where the information iscoming from. You have to drill right through to the child view to seethe raw table joins etc.Does anyone have any comments on this database design? I would love tohear your opinions and tales from the trenches.Best regards,Rod.

Which is more efficient? One large view that joins >=10 tables, or a few smaller views that join only the tables needed for individual pages?

Hello.
Newbie here. I've only been using SQL for about a year now and have some minor questions about sql objects that reference other objects.
We have some views which reference other views in the joins. I will call one the primary view and the one being referenced in the joins as the secondary view.
Recently we made changes to the secondary view.
After which the primary views which referenced it would not work because of this change and had to be 'refreshed' by using drop/create scripts which essentially just dropped it and recreated the exact same view. I do not recall the exact error message that was returned other than it seemed to suggest that it could no longer see the secondary view since it had been changed. Nothing in the primary view was changed in any way, just the secondary.
Some here where I work have suggested off hand that this was a recompile of the primary view because the contents of the secondary changed.
My questions are:
1. Exactly why did this happen and is there a proper name for it when it does?
2. The same problem does not seem to occur when we have stored procedures referencing views in the joins which had just been changed. Why is that?
Thanks for any help on the matter. I greatly appreciate it.

Hello,
to make a report easier I'm developing it using a view of joined views of joined views.
Is there any significant performance penalty as opposed to just having one big select?
Cheers.

Hello There,I'm trying to create a view that has calculations dependent oncalculations, where the problem resides is that each time I make acalculation I must create an intermediate view so I can reference aprevious calculation.for example lets say I have my_table that has columns a & b. now I wanta view that has a & b, c = a + b, and d = c + 1.this is grossly simplified, the calculations I actually use are fairlycomplex and copying / pasting them is out of the question.so what I have is my_view_a which makes column c, and my my_view_finalwhich makes column d (however, in my real application I have 5 of theseviews, a/b/c/d/e/)is there anyway I can consolidate all these views into one? I wasthinking of using a stored procedure with temp tables or somethingalong those lines.I just which I can use the aliases that I create for c in d in onestep.any insight would be greatly appreciated.

I have a text field in the form of numbers separated by periods like this: 1,1.2,1.2.1
When I sort, it works fine unless I get out to 10 digits.
Desired sort: 1,1.1,1.1.1,1.1.2,.....,1.1.9,1.1.10
Actual sort: 1,1.1,1.1.1,1.1.10,1.1.2,.....,1.1.9
The 10 is showing up smaller than the 2 because of the straight text comparison, any ideas on how to get around this?

I have a gridview that has AllowSorting="true" however I need to implement my own sorting because I have DateTime and Integer data types in several of the columns and I don't want an int column sorted like 1,12,2,23,3,34,4,45,5,56, etc. So, I've added SortParameterName="sortBy" and adjusted my stored procedure to accept this. For only ASC sorting, I've got
ORDER BY CASE WHEN @sortBy='' THEN DateCreated END, CASE WHEN @sortBy='DateCreated' THEN DateCreated END
and so on. However, columns can also be sorted with DESC. I tried CASE WHEN @sortBy='DateCreated DESC' THEN DateCreated DESC END, but I get a syntax error on DESC. How can I do this?

I am trying to set up custom paging and sorting with my gridview. All is well but the sorting. The problem is with the stored procedure. If I pass in the value @sortExpression as, for example "discussions_Posts.post_time", i does not sort it at all. But if I replace the @sortExpression with discussions_Posts.post_time in the actual stored procedure, it gets sorted. how do I sort this query with a input parameter with values like "discussions_Topics.topic_title" or something? ALTER PROCEDURE discussions_GetTopicsSubSet@startRowIndex as int,@maximumRows as int,@sortExpression as nvarchar(50),@board_id as intASDECLARE @Topics TABLE(RowNumber INT,topic_id INT,topic_title VARCHAR(50),topic_replies INT,topic_views INT,topic_type INT,topic_time DATETIME,post_id int,post_time DATETIME,Topic_Author_UserName nvarchar(256),Topic_Author_ID uniqueidentifier,Post_Author_Username nvarchar(256),Post_Author_ID uniqueidentifier)--DECLARE @TopicsFrom Datetime--SELECT @TopicsFrom = CASE @TopicsDays WHEN '1' THEN DATEADD(day,-1,getdate()) WHEN '2' THEN DATEADD(day,-7,getdate()) WHEN '3' THEN DATEADD(day,-14,getdate()) WHEN '4' THEN DATEADD(month,-1,getdate()) WHEN '5' THEN DATEADD(month,-3,getdate()) WHEN '6' THEN DATEADD(month,-6,getdate()) WHEN '7' THEN DATEADD(year,-1,getdate()) ELSE DATEADD(year,-1,getdate()) END-- populate the table CAST(getdate() as int)INSERT INTO @TopicsSELECT ROW_NUMBER() OVER (ORDER BY @sortExpression), discussions_Topics.topic_id, discussions_Topics.topic_title, discussions_Topics.topic_replies, discussions_Topics.topic_views, discussions_Topics.topic_type,discussions_Topics.topic_time, discussions_Posts.post_id, discussions_Posts.post_time, user_1.UserName AS Topic_Author_Username, user_1.UserId AS Topic_Author_ID, user_2.UserName AS Post_Author_Username, user_2.UserId AS Post_Author_IDFROM discussions_Topics INNER JOIN discussions_Posts ON discussions_Posts.post_id = discussions_Topics.topic_last_post_id INNER JOIN aspnet_Users AS user_1 ON user_1.UserId = discussions_Topics.topic_poster INNER JOIN aspnet_Users AS user_2 ON user_2.UserId = discussions_Posts.poster_idWHERE (discussions_Topics.board_id = @board_id ANDdiscussions_Topics.topic_type NOT LIKE '1' )SELECT * from @TopicsWHERE RowNumber BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1

This is more of a SQL question than a .NET question, but if you could indulge me, I'd appreciate it.
I have a table that has 2 columns of particular interest for the purposes of this question. One is a foreign key to another table (int), the other is a name (varchar(50). I want to sort the results set in a specific way. I want to sort it in such a way that all entries that have the foreign key = 0 come first (sorted ASC by name) then I'd like all the other results with foreign key column > 0 to be sorted ASC by name. I was trying to be cute and tried an order by statement like this: "ORDER BY (foreignKey > 0), name" but it's a syntax error (as I initially thought it might be). I know I could probably do a stored procedure that will create a temporary table and I could insert a new column to help put these in order, and I also know I could put all the results into an array, then sort the array in code, but I was just wondering if there was a simpler, slicker way (tricky SQL query perhaps).

Hi,
I hope I can explain what I am trying to achieve (in MS SQL Server):
The results set that shows Names and Dates (plus others, but not relevant here), that needs to be sorted by Date and then by name.
I have tried:
ORDER BY date, surname, forename (gives dates in right order but not names)
and
ORDER BY surname, forename, date (gives names in right order but not dates)
Thanks for any advice!

I noticed when looking at the execution path that the SQL sort (order by) was taking up 16% of the total for the query. However the execution time for the sort was like .007 ms in SQL so I doubt it was really that much overhead.
Is it more effecient to sort a dataset within my asp.net program?

i am trying to figure out how to sort the data in a column in an ascending way when the column contains numeric and char data.
In the example I want to sort by category,lookup value. However, as you can see the top two rows are sorted right but the others are all messed up.
I would really appreciate any hints you can give me.
thanks

I have a table with a composite primary key (ie a,b, autoInteger)
that includes an auto-incrementing system generated integer.
How do I sort out the records such that if a and b above repeat, I only
get the records with the highest autoInteger?
Thanks for any suggestions

I am trying to sort a matrix by column. I first tried adding an interactive sort to the column heading, but it either gave me a run-time error, or there was not response. I then tried adding sorting to the row groups, and that doesn't seem to work either. I feel I have done every combination of groupings and sort expressions. Has anyone been able to accomplish this?
Thanks,
Kris

Hi,
I'm not sure why this is happening, but I'm trying to sort/order on this special field/column that I have created to allow precise ordering. However, for all of the values that are returned, if there are any NULLS, they are returned first/ahead of the values of what I want to be returned first. This field/column I created is called 'POW' (stands for Priority on Web). The values are just integers, 1-whatever, and we try to make sure that they're all unique. So for example, if we have a 1 in that field, then that row should be returned first, and if another row has 2, then it should be next. However, this is not working exactly - all of the NULL values are returned FIRST, then the proper values in the correct order. I want the NULLS to be last, because it may take some time for someone to go into each record, and assign it a unique value. My current SQL statement reads:
mySQL = "SELECT SignTypes.Id, SignTypes.SignType, SignTypes.SignDescription, SignTypes.FinalSignWidth, SignTypes.FinalSignHeight FROM SignTypes JOIN PropLocSigns ON SignTypes.Id = PropLocSigns.SignTypeID WHERE PropLocSigns.PropLocID = " & Session("PropID") & " AND (RestrictOnWeb = 0 OR RestrictOnWeb IS NULL) ORDER BY SignTypes.POW; SELECT @@ROWCOUNT"
So if someone knows of a way to put NULLS last, and still have my proper ordering, that would be great! I would think that there's some simple way of doing this, but not being an expert, I don't know. Thanks for the help!

hi all..just a quick question about sorting a query. let us say that i am running a select statement that involves 3 or 4 tables and one of the columns in one of the tables is a divisions column. based on the records, there is a specific division that i want to appear first in the list. its not alphabetically possible nor is it the keys associated with it allow it to be selected first. how would i go about pulling that particular record from the divisions column to be listed first in my query? thanks alot

Hello,
I have an appointment table that stores the appt time as varchar. For example, 1:00 PM or 9:00 AM. When I say "ORDER BY Appointment.Time", it puts 1:00 PM before 9:00 AM. How do I make it put 9:00 before instead? Could you please help me out.
Please note, I store time as varchar because it is much more convenient for me through out the application that way.
Thank you very much.
