I have a vb.net page that I need to display a list of employees who work in a specific office, based on a MatterID passed in a query string. But, I don't know how to get a value returned from one sql statement into a second. Here's what I'm trying to do...
From the QueryString, we know that the MatterID = 4 ( xxx.aspx?MatterID=4)
Knowing that the Matterid=4, I query the database to get the OfficeId for that MID (Select OfficeID from tMatter where Mid=4) ~This returns an OfficeID of 6
So, then I need to do another query to get the employees where OfficeID = 6 (Select EmployeeID from tEmployees where OfficeID = 6)
How do I do these in one query, or how do I use the Calculated Value for the OfficeID in the 2nd statement?

Looking at a trace table and trying to remove all the "erroneous" bits in a string e.g the declares etc so I can purely get to proc names.
An example string
declare @p2 varchar(10) set @p2=NULL exec sp_proc @Code='TF',@TypeCode=@p2 output select @p2
I've tried
select top 5000 textdata,substring(textdata,charindex('exec',textdata)+5,charindex('@',textdata)-1)
from trace_table
where TextData like '%sp_%'
and TextData like '%declare%'
And it fails dismally...

Padding leading zeroes for the months in End date
Example: actual data is like
6222007
,11301998
in end date column the following query works fine for 11301998 and converts it as 19981130 which was correct.
But 6222007
fails because month has no leading zero and it converts it as 0076222 which is wrong.
How can i make it as 20070622 with the following code
select (case when replace (ltrim(rtrim(ltrim([end date]))), '|', '') in ('99999999','00000000') then NULL
else substring ([END DATE],5,4)+SUBSTRING([END DATE],1,2)+SUBSTRING([END DATE],3,2) end) as ConvEnd_date
from Mydatabase.dbo.[AccountTable]

Hi,I wrote two queries to search in three tables mp_parent, mp_page and mp_parentThe first one is: SELECT mp_page.PID, mp_page.PageID, mp_page.PageContent, mp_page.ParID, mp_page.ChiID, mp_parent.ParentName FROM mp_page INNER JOIN mp_parent ON mp_page.ParID = mp_parent.ParentID The second one is:SELECT mp_page.PID, mp_page.PageID, mp_page.PageContent, mp_page.ParID, mp_page.ChiID, mp_child.ChildName FROM mp_page INNER JOIN mp_child ON mp_page.ChiID = mp_child.ChildID I used this way to display the records in a FormView public HttpContext context = HttpContext.Current; public void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { ViewState["srch"] = context.Items["srch"]; } FormView1.DataSource = GetTable(); FormView1.DataBind(); } private DataTable GetTable() { SqlConnection SqlCon = new SqlConnection("Data Source=AJ-166DCCD87;Initial Catalog=mp;Integrated Security=True;Pooling=False"); String SQL1 = "select mp_page.PID, mp_page.PageID, mp_page.PageContent, mp_page.ParID, mp_page.ChiID, mp_parent.ParentID, mp_parent.ParentName from mp_page INNER JOIN mp_parent ON mp_page.ParID = mp_parent.ParentID where PageContent like '%" + Convert.ToString(ViewState["srch"]) + "%'"; SqlDataAdapter Adptr = new SqlDataAdapter(SQL1, SqlCon); SqlCommandBuilder CB = new SqlCommandBuilder(Adptr); DataTable Dt = new DataTable(); Adptr.Fill(Dt); return Dt; SqlCon.Close(); } the question is how can I check if one record is empty to witch to another query ??Is it possible to know without using QueryString?Thank you

Hi, I'm using the following to send two items in the querystring over to the next page, where I can display tables based on them. Both querystrings appear fine in the URL. The first querystring works fine to single out the order specified by the orderid from the querystring, but I can't seem to get my other sqldatasource to show the userid (+contents of aspnet_users table) using the userid I passed in the querystring. <asp:HyperLinkField DataNavigateUrlFields="OrderID,UserId" DataNavigateUrlFormatString="Copy of Orders.aspx?OrderID={0}&UserId={1}" DataTextField="OrderID, UserId" /> This is what I'm using to try and pick up the userid <asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource3" DataKeyNames="UserId"> <Columns> <asp:BoundField DataField="UserId" HeaderText="UserId" SortExpression="UserId" /> <asp:BoundField DataField="UserName" HeaderText="UserName" SortExpression="UserName" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString2 %>" SelectCommand="SELECT [UserId], [UserName] FROM [aspnet_Users] WHERE UserId = @UserId"> <SelectParameters> <asp:QueryStringParameter DefaultValue="UserId" Name="UserId" QueryStringField="UserId" Type="object" /> </SelectParameters> </asp:SqlDataSource>

If I script the SQL statement with a constant, deleting the record from the database works.
If I script the SQL statement to delete based on the WHERE clause being a variable name, it will not delete the record.
The value being compared in the WHERE clause comes directly from the Sequel database.
I have a dropdown box that is filled from the database. The dropdown1.selecteditem.text is placed in a variable. The script is to delete a record from the database where the table.name in the database equals the item name selected from the dropdown box.
This querystring does not delete the record from the database:
dim queryString As String = "DELETE FROM [Table1] WHERE ([Table1].[name] = 'variableCompareText')"
This querystring does delete the recrod from the database:
dim queryString As String = "DELETE FROM [Table1] WHERE ([Table1].[name] = 'John')"
Why can't I delete a record with a variable in the querystring? Otherwise, you would have to always know in advance which record to specify rather than being deleted dynamically.

I have a report that has 2 parameters. I use this report to do comparisons of performance data between two builds of our product. I'm not hosting this report in a seperate page, just using the standard sql reporting services web interface.
I'd like to be able to send out a link to this page that will load up the page with values for the parameters specified. I know in the report definition itself I can change the default parameter values, but I'd rather not change and redeploy the report every time I need to send it out for others to view.
My first thought was that it should be easy enough to specify the parameters as part of the url querystring and read the values in somehow using an expression for the parameters default value. Is this possible? I've done a bunch of searching but can't seem to find any good examples of this.

hi. i'm building a news section for some friends of mine. i list all the news items on the main page in a gridview. i've made a custom edit linkbutton that sends the user to an edit page, passing the news id as a quarystring variable. on the edit page i first check if the querystring variable contains an id at all. if not, i redirect the user to the main page. if an id is passed with the querystring, i fetch the matching news item from the database and place it in a formview control for editing.so far, so good. but what if someone types a random id in the querystring? then the formview won't show up and i'd look like a fool. :) therefore, i need some kind of check to see if the id exists in the database. if not redirect the user back to the main page... so i started thinking: i could check the databsae in a page_load procedure. if all is well, then display the news item. since the formview is automatically filled with the correct data, does that mean that i call the database two times? i mean, one for checking if the news item exists, and one for filling the formview. logically, this would be a waste of resources.help is appreciated.

I pass in 3 querystring parameters to my web form. The Object Data Sources pick up these parameters
and select the appropriate records.
I want to display one of the querystring parameters in my Page Header, specifically the one for Fiscal Year.
I could return the Fiscal Year in a column from the data source, but the Fiscal Year would not populate if
no records were returned...Therefore, I must get the querystring parameter that was originally passed in...
How do I populate the report control textbox with the value of querystring parameter?
Thanks!

We have the following two tables :
Link ( GroupID int , MemberID int )
Member ( MemberID int , MemberName varchar(50), GroupID varchar(255) )
The Link table contains the records showing which Member is in which Group. One particular Member can be in
multiple Groups and also a particular Group may have multiple Members.
The Member table contains the Member's ID, Member's Name, and a Group ID field (that will contains comma-separated
Groups ID, showing in which Groups the particular Member is in).
We have the Link table ready, and the Member table' with first two fields is also ready. What we have to do now is to
fill the GroupID field of the Member table, from the Link Table.
For instance,
Read all the GroupID field from the Link table against a MemberID, make a comma-separated string of the GroupID,
then update the GroupID field of the corresponding Member in the Member table.
Please help me with a sql query or procedures that will do this job. I am using SQL SERVER 2000.

In the Programmability/Stored Procedure of Northwind Database in my SQL Server Management Studio Express (SSMSE), I have the following sql:
USE [Northwind]
GO
/****** Object: StoredProcedure [dbo].[SalesByCategory] Script Date: 03/25/2008 08:31:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[SalesByCategory]
@CategoryName nvarchar(15), @OrdYear nvarchar(4) = '1998'
AS
IF @OrdYear != '1996' AND @OrdYear != '1997' AND @OrdYear != '1998'
BEGIN
SELECT @OrdYear = '1998'
END
SELECT ProductName,
TotalPurchase=ROUND(SUM(CONVERT(decimal(14,2), OD.Quantity * (1-OD.Discount) * OD.UnitPrice)), 0)
FROM [Order Details] OD, Orders O, Products P, Categories C
WHERE OD.OrderID = O.OrderID
AND OD.ProductID = P.ProductID
AND P.CategoryID = C.CategoryID
AND C.CategoryName = @CategoryName
AND SUBSTRING(CONVERT(nvarchar(22), O.OrderDate, 111), 1, 4) = @OrdYear
GROUP BY ProductName
ORDER BY ProductName

I executed the code successfully and I got a box which asked for "Enter the query string".
I typed in the following: EXEC dbo.SalesByCategory @Seafood. I got the following box: Query attempt failed. Must declare the scalar variable "@Seafood". I am learning how to enter the string for the "SQL query programed in the subQuery_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnQuery.Click" (see the code statements listed above). Please help and tell me what I missed and what I should put into the query string to get the information of the "Seafood" category out.
Thanks in advance,
Scott Chang

I have got a grid view which i want to query i have added a WHERE for it WHERE (([carinfo] = @carinfo) AND ([carmake] = @carmake) AND ([postcode] LIKE '%' + @postcode + '%') AND ([carprice] <= @carprice)) I have made a search page with 4 textboxes and a search button but what i cant same to get working is the code to take the infor from my text boxes and run the query on the grid view page.If i just had a query with (([carinfo] = @carinfo) i can get that to work by doing this Protected Sub SearchButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles searchButton.Click '~/Default2.aspx Response.Redirect("search.aspx?man=" + Carmake.Text) End Sub After that i just dont know what to do, my asp code for the Data Source is <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:addcar %>"
SelectCommand="SELECT [AdId], [carinfo], [carmake], [cartype], [carprice], [other1], [enginesize], [fuel], [listdate], [adtitle] FROM [classifieds_ex] WHERE (([carinfo] = @carinfo) AND ([carmake] = @carmake) AND ([postcode] LIKE '%' + @postcode + '%') AND ([carprice] <= @carprice))"> <SelectParameters> <asp:QueryStringParameter Name="carinfo" QueryStringField="man" Type="String" /> <asp:QueryStringParameter Name="carmake" QueryStringField="make" Type="String" /> <asp:QueryStringParameter Name="postcode" QueryStringField="postcode" Type="String" /> <asp:QueryStringParameter Name="carprice" QueryStringField="pricerange" Type="Decimal" /> </SelectParameters> if anyone could help me with this would be great i been trying to work this out for two days now. Keep safeNick

Hi,
I'm self learning asp.net and have a little experience in vb.net. What i'm trying to do is run an SQL query and write the results into variables. The SQL query's im running will only ever return 1 row (specifing primary key / uniqueID). This is becasue i dont want to output the results as a table, rather to other objects. (using VS Web Developer express 2008)
Currently my code is:
------------------------------------------------------------------------------------------------------------------------------------------------------
Imports System
Imports System.Data.SqlClientPartial Class details
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Dim VariablesDim job_id As Integer
Dim myConnection As SqlConnection
Dim var_jobid As String = ""
Dim var_2 As String = ""
Dim var_3 As String = ""Dim SQL_read As New Object
'Write valus to Variables
job_id = Request.QueryString(job_id)SQL_read = "SELECT * FROM TABLE_NAME WHERE job_id = " & job_id
'Write Variables and Text to labelsLbl_title.Text = "Details for Job " & job_id
Lbl_jobid.Text = job_id
'Try to Establish link to SQL Server
'===================================
TrymyConnection = New SqlConnection("server= [my server here] ; database=ServerLog ; User Id = sa; Password= [my password here]")
myConnection.Open()
--------------------------------------------------------------------------------------------------------------------------------
I realise the quality of the code may be pretty abismal, due to pretty much guessing my way through. I dont know how to basically 'run' my sql query for starters, and then to output the results into variables. -IE- coloumn 1 (row1) of my results being put into var_1, column 2(row1) being put into var_2 etc etc.
Thanks in advance
Luke
