Hello Everyone,
I am trying to create a query for the purpose of a nested repeater relation. The information needs to be pulled from one table. I have shortened the columns to the ones that are required.
table - Pages
ID
PageName
ParentPageID
So, take the following example:
ID 14, PageName - Service A, ParentPage ID = 6
ID 15, PageName - Service B, ParentPage ID = 6
ID 36 PageName - Client 1, ParentPage ID = 14
ID 37 PageName - Client 2, ParentPage ID = 14
ID 38 PageName - Client 3, ParentPage ID = 15
ID 39 PageName - Client 4, ParentPage ID = 15
So, I want to create a query that will get my nested repeater to display as follows:
Service A
Client 1
Client 2
Service B
Client 3
Client 4
What I have come up with so far is:
SELECT * from tbl_Pages WHERE ParentPageID IN (Select ID From tbl_Pages)
SELECT p.ParentPageID, p.PageName, p.ID FROM tbl_Pages p
The relation would be based off ParentPageID. I keep getting errors that either there is no unique value or the relation is null. What am I am missing here?
So I have code to fill my repeater with a data: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim cnn As Data.SqlClient.SqlConnection = New Data.SqlClient.SqlConnection(System.Web.Configuration.WebConfigurationManager.ConnectionStrings("db_ConnStr").ConnectionString) Dim cmd1 As Data.SqlClient.SqlDataAdapter = New Data.SqlClient.SqlDataAdapter("SELECT aspnet_Users.UserName, COUNT(forum_posts.post_id) AS IlePost, forum_posts_1.post_content, forum_posts_1.topic_id, forum_posts_1.post_id, forum_posts_1.post_date FROM aspnet_Users INNER JOIN forum_posts ON aspnet_Users.uID = forum_posts.user_id INNER JOIN forum_posts AS forum_posts_1 ON aspnet_Users.uID = forum_posts_1.user_id GROUP BY aspnet_Users.UserName, forum_posts_1.post_content, forum_posts_1.topic_id, forum_posts_1.post_id, forum_posts_1.post_date HAVING (forum_posts_1.topic_id = @topic_id) ORDER BY forum_posts_1.post_date ASC", cnn) cmd1.SelectCommand.Parameters.AddWithValue("@topic_id", Request.QueryString("ID")) Dim ds As Data.DataSet = New Data.DataSet cnn.Open() cmd1.Fill(ds, "posts") Repeater1.DataSource = ds.Tables("posts") Page.DataBind() cnn.Close() End Sub And I want to take the value from column which I bolded - IlePost. I want take this out at compare with some condition. For example:Dim label as label = Repeater1.Findcontrol("Label1")If COLUMN < 10 thenlabel.text = "Less than 10"elselabel.text = "More than 10"I hope you understand me :-)
do i need to nest a query in RS if i want a calculated column to be compared against a multi value variable? It looks like coding WHERE calcd name in (@variable) violates SQL syntax. My select looked like
SELECT ... ,CASE enddate WHEN null then 1 else 0 END calcd name FROM... WHERE ... and calcd name in (@variable)
I'm new to ASP.NET and i've been banging my head aganist this problem for a few days now.I have a repeater and then a repeater inside that repeater. <asp:SqlDataSource ID="sqlRepeater1" runat="server" ConnectionString="<%$ ConnectionStrings:Inspections_DBCS %>" SelectCommand="SELECT count(*) as mycount FROM insuranceco with (NOLOCK) where insurancecoid=@insurancecoid" OnSelecting="sqlRepeater_Selecting" > <SelectParameters> <asp:Parameter DefaultValue='' Name="insurancecoid" Type="String" /> </SelectParameters> </asp:SqlDataSource> <% 'sqlRepeater1.SelectParameters["insurancecoid"].DefaultValue = "123"; %>This returns:Description: An error occurred during the compilation of a resource required to service this request.

Hi there, In 2005.NET, if I used an asp:repeater, I would load the data from source and then manipulate it like so://load the data from source using a predefined connection and SQL Statement.private void LoadMyDataFromSource(){ try { connection.Open(); OleDbDataReader myReader = comm.ExecuteReader(); rptrCatList.DataSource = myReader; rptrCatList.DataBind(); myReader.Close(); } finally { connection.Close(); }} //catch the ItemDataBound event and manipulate the data how I wish before it's loaded into the Repeater.protected void rptrCatList_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { int title = 4; //this is the index of the column I wish to manipulate((Label)e.Item.FindControl("lblTitle")).Text = ((IDataRecord)e.Item.DataItem).GetString(title) + ":" } }This would give me all the flexbility I ever needed. But now I wish to use linq and since the IDataRecord relies on dataReader sources, I cannot obtain the same flexbility. Can anyone point me in the right direction for obtaining the same kind of flexbility but using a linq-to-SQL dataContext? I wish to manipulate mostData that comes through from my source, so: //loadng the data in via my linq-to-sql context.private void LoadProducts() { MyDataContext db = new MyDataContext (); var all = from p in db.Products_IncontinenceStandards where p.Product_Cat == "Category1" select p; rpterCat.DataSource = all; rpterCat.DataBind(); }This is where I get stuck because, even though I can still capture the ItemDataBound event since I have databound the Repeater to the linqSource, I can't access the individual fields (or this is what I think I can't do!), Does anyone know how to relate to this so I can create the same effect? Many Thanks,Nathan Channon
Hi,Please can somone help me with a nested SQL query. I have two tables please see belowTable 1CallIDEmployeeIDCallSummaryCallStatusTable 2CallHistoryIDCallIDDataAddedCallActionI would like to return the CallID, EmployeeID, CallSummary and CallStatus from Table 1, and also display the last CallAction from Table 2.This is a helpdesk database so a Call will have many CallActions i.e. Open, Held, Assigned Internal. How do I return the last CallAction Added against the selected CallID, I know I use the DateAdded but not sure about nested statements.The results I would like to return to the user would look like this:-Call ID: 1EmployeeID: 1Call Sumary: SQL ProblemCall Status: OpenCall Action (Last Action): Assigned Internal.
I want to write one query which will select multiple distinct records from one table For e:g Lets say in a table i have 3 fields name,tel_no,sex Now i want to list all the records which are distinct in each of these fields like distinct name,distinct address
Important Tables: Product (table of products) --ProductID --ProductName
ProductCategories (Associates a Product with one or more categories) --ProductID --CategoryID
Category (table of categories that a product may fall under) --CategoryID --CategoryName
Information:
Basically I have a product that falls into two categories. Therefore there are two records in the ProcuctCategories Table. I am trying to create a query that will find all products that are in categories 1 & 2.
Attempted Solution: SELECT * FROM Product WHERE (ProductID IN (SELECT CategoryID FROM ProductCategories WHERE CategoryID =1)) AND (ProductID IN (SELECT CategoryID FROM ProductCategories WHERE CategoryID =2))
This returned zero records though it should have returned the product that is in categories 1&2.

I want to build some paging functionality into my repeater (b4 you ask, datagrid not providing flexibility required for presentation).
I will have no problem with the VB logic but I will need to execute SQL that only returns results from x to y (e.g. results 21 thru 40 for page 2). I know I can do something like 'SELECT TOP 20 * FROM...', or something like it, for page 1. But, I'm not sure if it's possible to build SQL for the pages greater than 1. Any suggestions.
Q1 - I want to compare file names uploaded by users with the name of the file present in the database. I have a repeated control that shows the data alongwith an array of <input type=file> that is createddynamically when the data is displayed in the repeater control. (So there is an input tag within the ItemTEmplate tag in the repeater)Now I want to compare the names of the files uploaded by the user with the values as displayed in the repeater. Is there a way I can do this? So I need to be able to get the data (for example Name) as displayed in the repeater control into a variable like Dim strName As String. Something like: Dim strName As String = (value from the repeater control) Can I do this? How? Q2 - I want to return a value from a stored procedure that will be stored in a variable in VB and will be used for comparison. So, I want to return a 0 or 1 and then use .ReturnValue method to store this value. The problem that I am facing is that I am using a cursor. And as soon as return is called in the SP it exitsthe procedure and returns only one value (1 if found 0 otherwise) So it does not loop through the completecursor. What can I do to fix this? CODE: OPEN cur1--print 'Cursor Open'FETCH NEXT FROM cur1 INTO @varFile, @varFileEx, @varFileSt WHILE @@FETCH_STATUS = 0BEGINIF (@varFile = @FileName AND @varFileEx = @FileExt)BEGINset @varReturn = 0ENDELSE BEGINset @varReturn = 1ENDFETCH NEXT FROM cur_FileSystem INTO @varFileName, @varFileExt, @varFileStatusreturn (@varReturn)ENDCLOSE cur_FileSystemDEALLOCATE cur_FileSystem Please help. Thanks
Hi, I have a repeater which i need to build editing capabilities into in a similar way as the GridView, just a little unsure how to tie it together. Ideally i would like to use a GridView as this would do all of the work for me however it looks like I need to go with the repeater due to the nested nature of the data I am working with. What is the best way to go about updating the data source from within a repeater? I have already built the edit interface with some MultiViews in the Repeater control and handling the ItemCommand event, just not sure how to actually update the data source. Can I still use the SqlDataSource wizard to generate all of the SQL for me? If so, within the ItemCommand event handler I have the data i want to update back to the database by using the FindControl method and retrieving the Text, but how do i get this data into the SqlDataSource object and update the database? Are there any samples available which show how to update a datasource using a repeater? Your help is much appreciated trenyboy
Hi,I'm probably missing something obvious (either that or doing this totally wrong).I'm trying to use a nested loop to generate the following results:Unit Day1 Day2 Day3 Day4 Day5Name1 25 45 89 54 76Name2 48 54 81 74 98What I have so far is this:WHILE @FCount < @TotalFoodUnitsBEGINSELECT (SELECT Unit FROM tbl_acc_FoodVenues WHERE UnitID = (@FCount + 1)) AS Unit WHILE @FDCount < @Days BEGIN SELECT (SELECT FdRevenue_a FROM tbl_acc_aud_SportsAudits WHERE AudDate = DATEADD(day, @FDCount, @pdStartDate)) AS Rev SET @FDCount = @FDCount + 1 END SET @FCount = @FCount + 1ENDAny suggestions please
I am trying to write a query that does not use inner joins to see if it returns rows faster than a query using inner joins. My trouble is that I don't know how to write the syntax for the 3rd table that I am comparing against. Can I nest Exists in a Where clause? If so how is the 2nd exists statement added to the query? see my sample query below ================================================== === 'With 2 tables
SELECT DISTINCT s1.ID, s1.SITE FROM SITE_TBL s1 WHERE EXISTS (SELECT * FROM DEVICE_TBL d1 WHERE s1.ID = d1.SITE_ID AND d1.DELETEFLAG <> 'D') ORDER BY SITE
'with 3 tables this doesn't work
SELECT DISTINCT s1.ID, s1.SITE FROM SITE_TBL s1 WHERE EXISTS (SELECT * FROM DEVICE_TBL d1 WHERE s1.ID = d1.SITE_ID AND d1.DELETEFLAG <> 'D') AND (SELECT * FROM BIG_TBL b1 WHERE d1.fqdn = b1.xyz) ORDER BY SITE

Hi, I have the following scenario that I am not sure how to best tackle. Any advice or examples is appreciated.
I am creating a stored proc that requires a code to be passed to it. In return data gathered from 3 different tables will be returned. The big catch is that 1 of the tables resided in a differenct database.
So, here is the data layout.
Database 1, Table 1 contains the following fields: Job, CustID, ShipID, and ShipMethod.
So the first question is how should the stored proc look with an input parameter of "Job" and output of Job, CustID, ShipMethod, ShipID, Address, City, State, Zip, and CustomerName?
Secondly, which database should the stored proc reside?
Again, any advise, suggestions, pointers, etc. are appreciated.
Can anybody please tell me if a query such as this (Valid in MS Access) can work in SQL Server:
SELECT Description, Sum(Total) FROM ( SELECT Description, Total FROM Table_A UNION ALL SELECT Description, Total FROM Table_B UNION ALL SELECT Description, Total FROM Table_C ) GROUP BY Description
The group of unions work by themselves, but when I try to nest an outer query to do some a Summation(), I have syntax errors.
Any insight would be greatly appreciated. Thank you.
SELECT SUM (dbo.HOLDING.Shares_Par_Value_Qty * dbo.ASSET.Current_Prc) AS MarketValue FROM dbo.HOLDING INNER JOIN dbo.ASSET ON dbo.HOLDING.Property_Num = dbo.ASSET.Property_Num Group by dbo.HOLDING.Account_ID
Account_ID is the same in both the queries ie in both the tables Holding and Account.
I need the output like this
Select Account_Id, Branch_Cd, MarketValue from -------
But MarketValue should be calculated exactly in the above method. How do I combine these two queries. I need it asap. Help me out.
I have a database that contains a PERSONNEL table, a VISIT table, and a STARSHIP table. I am trying to generate a single column list of the personnel that are from Vulcan (PERSONNEL.PLANET) and all starships that have visited Vulcan (VISIT.PLANET). VISIT.SHIP and STARSHIP.REGISTRY columns contain the ships identifiers. How would I accomplish this? I am just beginning sql so please be nice ;)
I have the following result set #1 from the query below. As you can see, there are four different provider roles and four different physicians listed for the same case (acctnum). Is there a way I could add a nested select (or other method) which would allow me to list this case as one line item to appear in the manner of result set #2?

How to configure sqldatadapter with query like "select name ,id from tlb1 where id in (select id from tlb2 where dept=@dept)" Is the nested subquery is not allowed while configuring sqldaadapter? Swati
I need to create a query to list all the subfolders within a folder.
I have a database table that lists the usual properties of each of the folder.
I have another database table that has two columns
1. Parent folder 2. Child folder
But this table maintains the parent child relationship only to one level.
For example if i have a folder X that has a subfolder Y and Z. And Y has subfolders A and B. and B has subfolder C and D and C has subfolder E and F
The database table will look like
parentfolder child folder X Y X Z Y A Y B B C B D C E C F
I want to write a query which will take a folder name as the input and will provide me a list of all the folders and subfolders under it. The query should be based on the table (parent - child) and there should not be any restriction on the subfolder levels to search and report for.
I have been banging my head to do this but i have failed so far. Any help on this will be highly appreciated.
I'd appreciate some help with the issue below - my SQL is a bit rusty and was never that hot to be frank. I'm using SQL Server 2000 (although have a test box with 2005 Express also). I've trawled MSDN and a few forums but can't find the solution (maybe I don't know what I'mm looking for!), so any help would be marvellous...
I have a table with a field called 'IRV' containing a string of comma-separated values. I want to be able to query a point in that string and count the number of times a given value appears. So...as an example, I want to count how many times '1' appears at position 7 in the IRV. I can create SQL to do this as follows:
SELECT COUNT(X) AS is1 FROM myIRVtable WHERE (SUBSTRING(IRV, 7, 1) = '1')
So far so good. However, it is also possible that the value at position 7 in this string could be '2' (or '3', or '4', etc) - and rather than re-running the query again and again to get these values, I'd like to do it in one hit.
How can I combine all this together - anyone have any brilliant solutions?
I have a table that refers to itself, and I need to loop through it to get the total number of entries in the structure with an object_type of 40 this is the function I came up with to do this. The problem is that the nested function doesn't seem to get called.

I am trying to limit a result set by ROW_NUMBER. However, I am having problems getting it working.
The following query works fine, and I get a result set with PollID, AddedDate and RowNum columns.
SELECT *, ROW_NUMBER() OVER (ORDER BY Results.AddedDate DESC) AS RowNum FROM
( SELECT DISTINCT p.PollID, p.AddedDate
FROM vw_vs_PollsWithVoteCount p
JOIN vs_PollOptions o ON p.PollID = o.PollID
) AS Results
However, as soon as I add a WHERE condition:
SELECT *, ROW_NUMBER() OVER (ORDER BY Results.AddedDate DESC) AS RowNum FROM
( SELECT DISTINCT p.PollID, p.AddedDate
FROM vw_vs_PollsWithVoteCount p
JOIN vs_PollOptions o ON p.PollID = o.PollID
) AS Results
WHERE RowNum BETWEEN 1 AND 10
The query fails with an ' Invalid column name 'RowNum' ' error.
I have tried using 'Results.RowNum' but I get the same problem.
I don't understand what the issue is. The result set has a column headed 'RowNum' so why can't I apply a WHERE clause to this column? I can apply WHERE to the PollID column, for example, with no problem.
I'm about ready to pull my hair out. I have a repeater control, and a date field. If the field is a valid date, I'll use it to calculate and display the person's age. Otherwise, I want to display "N/A". My problem is trying to determine if the date field is null or not.I'm using SQL Server 2005 which allows Nulls in the date field, and for many records I don't have a birth date. It makes sense for these records to leave the date Null. This is my code:Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles Repeater1.ItemDataBound If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then Dim LabelIcon As Label = CType(e.Item.FindControl("LabelIcon"), Label) Dim LblAge As Label = CType(e.Item.FindControl("LblAge"), Label) Dim inmate As WAP.prisonmembersRow = CType(CType(e.Item.DataItem, System.Data.DataRowView).Row, WAP.prisonmembersRow) If System.IO.File.Exists(Server.MapPath("~/images/picts/" & inmate.FILE2 & ".jpg")) Then LabelIcon.Visible = True End If If inmate.DATE_OF_BIRTH Is DBNull.Value Then If IsDate(inmate.DATE_OF_BIRTH) Then LblAge.Text = "Age: N/A" Else LblAge.Text = "Age: " & GetBirthdate(inmate.DATE_OF_BIRTH) End If End If End IfEnd Sub How can I resolve this?Diane
I have added some SQL to an Access form which updates the dbo_BM_Map table when the user hits the Apply button. There is a temp table with various fields, two being "Chapter_No" and "Initial_Mapping_Complete" which the update is based on.
I want this update to only apply to chapters that only have one name in the "Initial_Mapping_Complete" column. If a chapter has more than one then the update should ignore it. The attached screengrab shows you. The update should ignore chapter 19 as there are two people (Jim and James) in the Initial_Mapping_Complete field. Here is my code.
pdate dbo_BM_Map inner Join Temp_Progression_Populate on dbo_BM_Map.Product_ID = Temp_Progression_Populate.Product_ID Set dbo_BM_Map.Initial_Mapping_Complete = Temp_Progression_Populate.Initial_Mapping_Complete Where dbo_BM_Map.Chapter_No = Temp_Progression_Populate.Chapter_No And Temp_Progression_Populate.Initial_Mapping_Complete in (Select count(Initial_Mapping_Complete), Chapter_No from Temp_Progression_Populate Group by Chapter_No Having Count(Initial_Mapping_Complete) = 1)
