.net - One Dataset With Multiple Results Sets (multiple Select Statements) SQL Reporting Service?
Oct 15, 2011I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?

View 12 RepliesUse Multiple Statements In A For Loop?
May 8, 2011I have a piece of code that loops through the rows in a database and brings out information.
The code is attached to a button(search). To search for data, you enter a phone number, the loop goes through the data rows and bring out the information is it is there.
Everything works great accept I have added a second table to the database.
So do I add a whole new loop statement? Example lets say I had a new data row, how can I add that to this statement so that both tables are searched?
This is the code:
Dim strGetRecord As String = masTxtPhoneField.Text
For validData = 0 To storedtData.Rows.Count - 1

DB/Reporting :: Using Parameters With Multiple SQL Statements?
Jun 25, 2009I have a connection to a MS SQL database, which I understand is capable of handling multiple SQL statements in one Execution, ie
Code:
Using cmdExe As New System.Data.SqlClient.SqlCommand
sSQL = "Delete * from mytable where UniqueID=123;Insert into mytable (UniqueID, Field) values (123, 'something')"
cmdExe.CommandText = strSingleSQLLine
cmdExe.ExecuteNonQuery()
End Using
will delete from "mytable" and insert a new record all at once. This is great, but I want to expand upon that to use parameters because using string concatenation in my SQL queries is a bad idea. Now my question is this. If I add a parameter which is used in multiple SQL statements, do I have to add the parameter VALUE twice to the command object? ie, will the following code work?
Code:
Using cmdExe As New System.Data.SqlClient.SqlCommand
sSQL = "Delete * from mytable where UniqueID=@uniqueID;Insert into mytable (UniqueID, Field) values (@uniqueID, 'something')"
cmdExe.Parameters.AddWithValue("@uniqueID", 123)
[code]....
There are two questions here actually...can I add the parameters before setting the command text, and do I have to add the same parameter over and over again?
Running Multiple SQL Statements In One Operation
Apr 21, 2009I'm trying to use ADO to create several tables at once, into MS Access. Is it possible to do multiple statements in the one operation?[code]This fails due to a "Syntax Error in CREATE TABLE statement", although each of the create statements work on their own perfectly. Is there a way of doing this sort of thing? There will also be statements to add constraints, add indexing, etc., and I'd really like to be able to do it so that I don't have to split up the string into separate parts.

Asp.net - Improve The Design Of A Page With Multiple Case Statements?
Aug 17, 2011My page contains: GridView1, GridView2, Button1, Button2, DropDownList1 I bind Gridviews to the table selected in dropdown like this:

Select Case ddl1.SelectedValue
Case 0

For me it looks like a lot of overhead. How can I improve then design and only specify that I'm working on the following record in dropdown list without specifying the Case condition every time? Should I change my design or leave it like it is?

View 1 RepliesHow To Make A Statement Run If All Conditions Are True From Multiple Condition Or If Statements
Mar 22, 2011I have a form that contains multiple conditional or if statements on several defferent for controls.
Example: Radio Buttons, TextBoxes and CheckBoxes.
I am intending to create an order form(demo) where the user can select multiple products.
I have a default order number that changes by one everytime an order is successful.
An order is only successful if all the information on the form is entered correctly.
My question is where do I insert the code for the order number?
Basically for the order number I have a counter that count by increment of one if an order is successful.
Meaning when the user hit place order, and all the infromation is right, then the order numer goes to 1 from zero.
Where do I add the condition for the order number since all the fields must first be completed.
Do I have to create a whole line of if else statements?
LINQ Query With Multiple OrderBy Statements Added In Loop
May 11, 2012I have a method in a webservice that has parameter with which users can decide how they want to order their results. This is a List(Of String) with the names of the fields in the order they want to sort them. I know I can normally order on multiple columns by doing the following
Dim test = Bars.OrderBy(Function(x) x.Foo) _
.ThenBy(Function(x) x.Bar) _
.ThenBy(Function(x) x.Test)
However in this case this won't work since I can't chain the ThenBy function because I'm adding the sorting orders in a loop. To use ThenBy I need an IOrderedQueryable collection. This is how I would want it to work
Dim sortColumns = {"Foo", "Bar", "Test"}
Dim query = From b in Bars
For each column in sortColumns
Select Case column
Case "Foo"
query = query.Orderby(Function(x) x.Foo)

VB Memory Usage - Open The Form That Is Linked To Multiple Tables - It Jumps To 157 Mb?
Aug 1, 2011I have an VB application that I developed in Visual Studio 2008. The back end is SQL. Application stores quite a bit of information and gets updated daily by users. It also connects to AD to get u/p, adds new accounts in AD and adds mailboxes. Users connect to it through Citrix. We noticed big spikes in memory usage. The executable itself is less than 5Mb; if I run it and it opens main form - memory usage jumps to about 19Mb, open a report - it jumps to 80 Mb. If I open the form that is linked to multiple tables - it jumps to 157 Mb. Once users start pulling new information in, update it and connect to AD or Exchange - it could jump to 250 Mb. Also noticed that if user with read only rights has application opened and idle - memory usage constantly changes with a pattern
like 17Mb - 19 Mb - 15 Mb - 17 Mb and so on. This user wasn't even using computer at the time. In general - what could cause such jumps in memory usage? What is the best way to prevent it? On the server we have Windows Server 2003 SE
