Sort On Field Constructed In Query
Aug 3, 2007
I want to sort on a field that I construct during a query....how can I solve this?
Basically what i am doing is selecting mediafiles with comments in descending order. (so mediafile with most comments on top)
Here's my (not working) query, because it throws the error that the mediaComments column is unknown....
SELECT *
FROM
(
select ROW_NUMBER() OVER (ORDER BY mediaComments DESC) as RowNum,
m.title,m.usercode,mediaComments=(select count(*) from MediaComments where mediaid=m.mediaid)
FROM Media m
WHERE m.usercode>0
group by m.title,m.usercode
) as Info
WHERE RowNum between @startRowIndex AND (@startRowIndex + @maximumRows-1)

I can do this in an old (~2003) way, but I'm trying to figure out a new (2005) way. What I've got is an e-commerce project in which users select various products from a catalog and add them to a shopping cart. Then they go to a checkout page which displays the current contents of the shopping cart, which are contained in a manually-constructed data table (system.data.datatable).
On the checkout page a GridView displays the contents of the data table. At that point they can check out via button click, which launches the following (somewhat simplified) ADO.NET code:1 Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
2 'Some variables
3 Dim intCounter As Integer 'Used to count the loop
4 Dim prmQuantity As New System.Data.SqlClient.SqlParameter() 'A parameter
5 Dim prmProduct As New System.Data.SqlClient.SqlParameter() 'A parameter
6 Dim prmPrice As New System.Data.SqlClient.SqlParameter() 'A parameter
7 Dim InsertCommand As New System.Data.SqlClient.SqlCommand 'The SQL insert command
8 Dim dbConnection As New System.Data.SqlClient.SqlConnection 'The connection to the DB
9
10 'Set the parameters for the SQL statement
11 prmQuantity.ParameterName = "@Quantity"
12 prmQuantity.SqlDbType = Data.SqlDbType.Int
13 prmQuantity.Size = 18
14 prmQuantity.Direction = Data.ParameterDirection.Input
15
16 prmProduct.ParameterName = "@Product"
17 prmProduct.SqlDbType = Data.SqlDbType.VarChar
18 prmProduct.Size = 50
19 prmProduct.Direction = Data.ParameterDirection.Input
20
21 prmPrice.ParameterName = "@Price"
22 prmPrice.SqlDbType = Data.SqlDbType.Int
23 prmPrice.Size = 18
24 prmPrice.Direction = Data.ParameterDirection.Input
25
26 'Create the connection to the database using web.config
27 dbConnection.ConnectionString = ConfigurationManager.ConnectionStrings("MyDB").ConnectionString
28
29 'Various command settings
30 InsertCommand.CommandText = "INSERT INTO [Orders] ([Quantity], [Product], [OrderDate], [ItemPrice]) VALUES (@Quantity, @Product, {fn NOW()}, @Price)"
31 InsertCommand.CommandType = Data.CommandType.Text
32 InsertCommand.Connection = dbConnection
33
34 'Add the rows to the database
35 For intCounter = 0 To objDT.Rows.Count - 1
36
37 'Re-inserts the data rows from objDT
38 objDR = objDT.Rows(intCounter)
39
40 'Set param values
41 prmQuantity.Value = objDR("Quantity")
42 prmProduct.Value = objDR("Product")
43 prmPrice.Value = objDR("Price")
44
45 'Add params to insert command
46 InsertCommand.Parameters.Add(prmQuantity)
47 InsertCommand.Parameters.Add(prmProduct)
48 InsertCommand.Parameters.Add(prmPrice)
49
50 'Open connection
51 InsertCommand.Connection.Open()
52
53 'Execute the insert command
54 InsertCommand.ExecuteNonQuery()
55
56 'Close connection and clear parameters for the next loop
57 InsertCommand.Connection.Close()
58 InsertCommand.Parameters.Clear()
59
60 Next
61
62 Response.Redirect("done.aspx")
63
64 End Sub
65
What I'd like to do is see if I can instead use a simplified approach based on 2.0 controls. Specifically, I was hoping that I could use an SqlDataSource and simply tap into its built-in Insert capabilities. So I tried this alternate procedure:Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs)Dim intCounter As Integer 'Used to count the loopFor intCounter = 0 To objDT.Rows.Count - 1DSOrdersNew.InsertParameters("Product") = objDR("Product")DSOrdersNew.InsertParameters("Quantity") = objDR("Quantity")DSOrdersNew.Insert()NextEnd SubWhen I run this I get an error message saying: "Unable to cast object of type 'System.String' to type 'System.Web.UI.WebControls.Parameter'."Am I just way out in left field here? I guess I don't mind doing it the old-fashioned way, but it seems like there ought to be a way to do this. Any suggestions would be appreciated. Thanks!

I am creating a report using report builder and I am using several fields from various entities. Is there a way to sort the data in the report using a field that is not being displayed in the report? The "sort and group" option lists only fields that are selected for output in the report... but is there a way to do sorting using a field that is not displayed in the report?

OK I have a report that needs an interactive sort on a calculated field. I get the message: "Report items cannot be used in sort expressions"
That's the whole reason we purchased SS*S and are putting up a Data Warehouse, so we can rank and analyze our data. Surely there is a way to do this??
Thanks for any advice!

Hello,
I have a report that calculates a field and therefore it does not exist in the dataset.
Can I perform an interactive sort on the textbox that contains this calculation?
Many thanks.

I'm trying to find a way to sort my query like the following:
SELECT * FROM tbl_Post WHERE ID = 3 OR ID = 1 OR ID = 4 OR ID = 2 ORDER BY (3,1,4,2)
Now if ID is my primary key, the sort by default would be 1, 2, 3, 4.
I would like to specify order so that I could return the order as 3, 1, 4, 2 if I wanted to.
Is there any way to do this?
Thanks,Russ

I have three tables:tblBook has the fields bookID, bookRangeID, bookSubjectID, bookCodetblBookRange has the fields bookRangeID, bookRangeDescriptiontblBookSubject has the fields bookSubjectID, bookSubjectDescriptionso some typical data in tblBook might be:1, 1, 1, B1HBSCI2, 1, 2, B2HBFRE13, 1, 3, B3HBGER4, 2, 1, B4PBSCI5, 2, 2, B5PBFRE6, 2, 3, B6PBGER7, 3, 1, B7CDSCI8, 3, 2, B8CDFRE9, 3, 3, B9CDGER110, 3, 3, B10CDGER211, 1, 2, B11HBFRE2tblBookRange would be:1, HardBack2, PaperBack3, CD RomtblBookSubject would be:1, Science2, French3, GermanI'd like to create a query which will return me the subjects along thetop, the book range down the side, and the bookcodes in the cells, abit like this:BookRange , Science, French, GermanHardBack , B1HBSCI, B2HBFRE1 B11HBFRE2, B3HBGERPaperBack , B4PBSCI, B5PBFRE, B6PBGERCD Rom , B7CDSCI, B8CDFRE, B9CDGER1 B10CDGER2Does that make any sense? So basically I'd like to get some kind ofdynamic SQL working which will do this kind of thing. I don't want tohard code the subjects in or the book ranges. I get the feeling thatdynamic SQL is the way forward with this and possibly using a cursor ortwo too, but it got quite nasty and convoluted when I tried variousattempts to get it working. (one of the ways I tried included workingout each result in a dynamic script, but it ran out of characters asthere were too many "subjects".)If anyone has any nice but quite dynamic solutions, I'd be delighted tohear.(and I know some of you have already told me you don't like tablesbeginnig with tbl, but I'm not hear for a lecture on namingconventions, I'm hear to learn and share ideas :o) )

I have a field called "type" in my "school" table that can have threepossibilities:ElementaryMiddleHighIn my result set, I always want Elementary to come first, Middle tocome second, and High to come third. An alpha sort gets me this:ElementaryHighMiddleSure, I could create a look-up that assigns an integer to the "type"field to get the right sort order (i.e. elementary = 0, middle = 1,high = 2) ... but is there a better way to do this with SQL syntax?Thanks,Ralph NobleJoin Bytes!

I am trying to set sorting up on a DataGrid in ASP.NET 2.0. I have it working so that when you click on the column header, it sorts by that column, what I would like to do is set it up so that when you click the column header again it sorts on that field again, but in the opposite direction. I have it working using the following code in the stored procedure: CASE WHEN @SortColumn = 'Field1' AND @SortOrder = 'DESC' THEN Convert(sql_variant, FileName) end DESC,
case when @SortColumn = 'Field1' AND @SortOrder = 'ASC' then Convert(sql_variant, FileName) end ASC,
case WHEN @SortColumn = 'Field2' and @SortOrder = 'DESC' THEN CONVERT(sql_variant, Convert(varchar(8000), FileDesc)) end DESC,
case when @SortColumn = 'Field2' and @SortOrder = 'ASC' then convert(sql_variant, convert(varchar(8000), FileDesc)) end ASC,
case when @SortColumn = 'VersionNotes' and @SortOrder = 'DESC' then convert(sql_variant, convert(varchar(8000), VersionNotes)) end DESC,
case when @SortColumn = 'VersionNotes' and @SortOrder = 'ASC' then convert(sql_variant, convert(varchar(8000), VersionNotes)) end ASC,
case WHEN @SortColumn = 'FileDataID' and @SortOrder = 'DESC' THEN CONVERT(sql_variant, FileDataID) end DESC,
case WHEN @SortColumn = 'FileDataID' and @SortOrder = 'ASC' THEN CONVERT(sql_variant, FileDataID) end ASC And I gotta tell you, that is ugly code, in my opinion. What I am trying to do is something like this: case when @SortColumn = 'Field1' then FileName end,
case when @SortColumn = 'FileDataID' then FileDataID end,
case when @SortColumn = 'Field2' then FileDesc
when @SortColumn = 'VersionNotes' then VersionNotes
end
case when @SortOrder = 'DESC' then DESC
when @SortOrder = 'ASC' then ASC
end and it's not working at all, i get an error saying: Incorrect syntax near the keyword 'case' when i put a comma after the end on line 5 i get: Incorrect syntax near the keyword 'DESC' What am I missing here? Thanks in advance for any help -Madrak

I have the following SQL:
select convert(datetime,'04-20-' + right(term,4)) as dt,
'Deposit' as type, a.* from
dbo.status_view a
where right(term,4) always returns a string which constitutes a 4 digit year eg '1999','2004',etc.
The SQL above returns
2004-04-20 00:00:00.000 Deposit ...
Which makes me think that it is able to successfully construct the datetime object inline. But then when I try and do:
select * from
(
select convert(datetime,'04-20-' + right(term,4)) as dt,
'Deposit' as type, a.* from
dbo.status_view a
) where dt >= a.submit_date
I get the following error:
Syntax error converting datetime from character string.
Given that it executes the innermost SQL just fine and seems to convert the string to a datetime object, I don't see why subsequently trying to USE that datetime object for something (in this case comparison with submit_date which is a datetime in the table a) should screw it up. Help!!! Thanks...

Hi Everyone,I am creating a portal and want the user to be able to select four variants from four separate drop down boxes... Such as chapter, story, etc... The user will then be able to click Find and shorten up the gridview list. The below query is what I am using for my current gridview (with custom paging). What I want to do is something like this: Pass a variable such as @Story. If no Story is chosen, then the variable would be *. If a variable is chosen, the the @Story would the StoryID. However, I don't believe SQL recognizes the * in this case. I was thinking it should, but I don't believe it does. I was hoping it would just take it and I could write, SELECT * from Stories where StoryId=@Story, or something like that... and if * was @Story, then it would just select all... or if it was 1, then just stories with a StoryId of 1.Am I totally off base here? Thanks! CREATE PROCEDURE SortAllStories@startRowIndex int,@maximumRows int,@totalRows int OUTPUTASDECLARE @first_id int, @startRow intSET @startRowIndex = (@startRowIndex - 1) * @maximumRowsIF @startRowIndex = 0SET @startRowIndex = 1SET ROWCOUNT @startRowIndexSELECT @first_id = StoriesID FROM Storie ORDER BY StoriesIdPRINT @first_idSET ROWCOUNT @maximumRowsSELECT Stories.StoryId, Chapters.ChapterName, Chapters.EnglishName, Translations.Translation,Stories.Verse, Stories.StoryFROM Chapters, Stories, TranslationsWHERE Chapters.ChapterId=Stories.ChapterId AND Translations.TranslationId = Stories.TranslationId AND Stories.StoryId >= @first_idORDER BY Stories.StoryIdSET ROWCOUNT 0SELECT @totalRows = COUNT(StoryId) FROM Stories

I was wondering if someone could help me here with some reporting I'm trying to do. For website visits, I currently use getdate() to have SQL insert the date and time of the visit in the table. I was wondering, is there a way to grab just the month from the field? I would like to chart this and I need to group the visits by month. I'm not sure how I would go about filtering just the month out of the entire date and time fields.

Right now I have one view that grabs records and sums up related records etc.... and returns a result. So basically it has the ID number and the number I calculated. THen I have another view that takes that number and performs calculations on it into three different columns. Is there any way to make these two view into one without a lot of repetative statements? Here is an example:
SELECT (tblTest.Quantity * tblTest.Price) as SubTotal, SubTotal * 1.06 as Total
Obviously that doesn't work, but what could I do to get that basic thing to work?
