Dataset.Tables.Count=0 Where There Are 2 Rows In The Dataset.
I havea stored procedure attached below. It returns 2 rows in the SQL Management studio when I execute MyStorProc 0,28. But in my program which uses ADOHelper, it returns a dataset with tables.count=0.
if I comment out the line --If @Status = 0 then it returns the rows.Obviously it does not stop in
if @Status=0 even if I pass @status=0. What am I doing wrong?
Any help is appreciated.

ALTER PROCEDURE [dbo].[MyStorProc]


@Status smallint,

@RowCount int = NULL,

@FacilityId numeric(10,0) = NULL,

@QueueID numeric (10,0)= NULL,

@VendorId numeric(10, 0) = NULL





If @Status = 0


SELECT ......
If @Status = 1

Filter One One Dataset With Values In Another Dataset?

I have two datasets in my report, D1 and D2.

D1 is a list of classes with classid and title

D2 is a list of data. each row in D2 has a classid. D2 may or may not have all the classids in D1. all classids in D2 must be in D1.

I want to show fields in D2 and group the data with classids in D1 and show every group as a seperate table. If no data in D2 is available for a classid, It shows a empty table.

Is there any way to do this in RS2005?

Create A New Dataset From Dataset

Here's what I'm trying to acomplish, I have an OLE DB Source that reads a table; for each record in the table I need to run a SQL Command that retrieves information from another set of tables based upon the input data; then I would like to iterate through that resulting dataset from the SQL Command and perform another SQL Command updating the database. Here's what I've tried: OLE DB Source to OLE DB Command, however I can't view the output of the command. Any help will be much appreciated.

Dynamic Dataset For Another Dataset!
Hi experts,

I'm not sure my design is normal or not. Please give me some advice.

I've a dataset and query by a field name 'companyid'.

select * from companyid where companyid = @icompany which @icompany is a input field.

if user select all, i'll send 0 to @icompany then I need to select all records.

question 1. How can I get all records? (i think about this query select * from companyid <> 0)

if user select for example companyid = 1, i'll send 1 to @icompany and the query work fine.

question 2. How can I change the query to adopt this 2 condition?

Thanks a lot,

XML To DataSet To SQL
I am faced with a common situation but there is a little twist that makes it unique and has me stumped. Hopefully someone can point me to a solution or give me enough guidance to figure it out.
Here is the situation, I am loading an XML file into a Dataset and need to update SQL tables from that Dataset but the tables are slightly different than in the DataSet. I am using C#, 2.0, visual studio 2005 and sql server 2005.
When I loaded the XML into the Dataset, the Dataset contained 19 tables. I individually loaded each table from the Dataset and determined from that which tables I needed and didn't need as well as determinined which fields I needed or not. I used this information to create my SQL tables.
Briefly, when creating the SQL tables, I used the dataset table name as the SQL table name and used the same column names as well. the only difference from the Dataset tables and SQL tables is 1 column has a different name (or to be more specific, a column exists in the datset that does not exist in the sql table and a column exists in the SQL table that does not exist in the dataset table). Also, some tables in the dataset do not exist in the sql Database.
I know that I can spin through each row of the tables I need in the Dataset and create an insert command from the row data and insert that into the SQL table but I have 11 tables to do that with. I would like to take advantage  of ADO.NET and push the datset information into sql data but I am confused on how to do this.
I am confused because not all tables in the dataset are represented in the sql database and though the tablenames and most of the columns have the same name, it is not an exact fit.
Can anyone point me to a solution or give me a good game plan that I can search on to help me load my dataset info to a sql DB.
I appreciate any help I can get.

Using Only One Dataset

I am using the following stored procedure, but as it is now it returns 2 datasets. I need it to return only 1.

@Location varchar(250),
@FromDate datetime,
@ToDate datetime


CREATE TABLE #Temp1 (themonth varchar(12), theyear varchar(12), averagedaystofilltotal float, averagefillratetotal float,
delaytimetotal float, responsetimelagtotal float)

INSERT INTO #Temp1(themonth, theyear, averagedaystofilltotal, averagefillratetotal, delaytimetotal, responsetimelagtotal)
EXEC rptStatsGraphicalYEARoverYear @Location, @FromDate, @ToDate

Create table #Temp2(averagedaystofilltarget float, averagefillratetarget float, responsetimelagtarget float)
INSERT INTO #Temp2(averagedaystofilltarget, averagefillratetarget, responsetimelagtarget)
EXEC Test1

Select * from #Temp2

drop table #Temp1
drop table #Temp2

Would anyone have any suggestions on how to modify this procedure so that it returns only one dataset, but yet still keeps the data seperated? Or is this even possible?

What's In A Dataset Name?
I have come into a company where my predesessor used a TON of differently named RDS files to connect to the same SQL Server Database; the same connection string, login id, etc. My suspicion is that he thought that datasources were the same as datasets and created one for each. I can't find a difference in any of them; except their name.

Is there any good reason to do this?

Should they all have been changed to be something generic like "ConnectTo{servername}Production.RDS (instead of {Report Name}.RDS)??? What is the easyiest way to change them all to the same RDS file?

Any thoughts?

Dataset WHERE Clause
I've created quite a complicated Dataset to enable users to search for names in a database.
Is there a way I could modify the WHERE clause without having to rebuild the Dataset each time?
I'd like to support general search criteria ie.
1) quotes, so WHERE NameSearch LIKE '%FirstName Surname%'
2) unlimited multiple keywords, so WHERE (NameSearch LIKE '%FirstName%' ) AND (NameSearch LIKE '%NickName%')
The query has already been built (and tested), so the problem is only with generating the WHERE clause, particularly when I'm not sure how many keywords are involved.
Any help would be greatly appreciated.
Thanks, Pete.

I thought it might have to do with the data I'm passing in the session string from the previous page.  Here is that code:Protected Sub cmdSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdSubmit.Click
Session.Add("Shift", shShift.SelectedItem)Session.Add("Type", shType.SelectedItem)
Session.Add("SelDate", OccDate.SelectedDate)

I loop through that data to load a check list which also works wonderfully.
 two questions based on that.
1) can i add a column after the fact? I want to basically update the the info in the dataset to store if the record was checked in the check list. if not, i can manipulate one of the already defined columns, but i would rather not.
2) what is the best way to update data with in the dataset? Never really done anything but pull data from one. how do i locate the correct row to update ("select name from tbl where name = " + checklist.items[index].tostring(); update row)
sorry for the fairly basic question. i appreciate the help.

Help Filling Dataset
I have a class that works fine using the SQLDataReader but when I try and duplicate the process using a Dataset instead of a SQLDataReader it returnsa a null value.
This is the code for the Method to return a datareader
publicSqlDataReader GetOrgID()
 Singleton s1 = Singleton.Instance();
 Guid uuid;
uuid = new Guid(s1.User_id);
 SqlConnection con = new SqlConnection(conString);
 string selectString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
 SqlCommand cmd = new SqlCommand(selectString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
 SqlDataReader dtr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
 return dtr;
This is the code trying to accomplish the same thing with a Dataset instead.
 public DataSet organID(DataSet dataset)
 Singleton s1 = Singleton.Instance();
 Guid uuid;
uuid = new Guid(s1.User_id);
 string queryString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
 SqlConnection con = new SqlConnection(conString);
 SqlCommand cmd = new SqlCommand(queryString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
 SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = cmd;
 return dataset;
Assume that the conString is set to a valid connection string. The Singlton passes the userid in from some code in the code behind page ...this functionality works as well.
So assume that the Guid is a valid entry..I should return a valid dataset but its null.
 Additionally if I change the sql query to just be Select * From aspnet_OrgNames I still get a null value...I am assuming I am doing something wrong trying to fill the dataset.
Any help would be appreciated.

Dataset StoredProcedures
I need to create a page where I can Select, Update, Insert and Delete users.
I use aspnet_Users and a table that I created and I call UserInformation, where I store address, phonenumbers etc. 
I am trying to use DataSet and StoredProcedures.  I call the following StoredProcedures for Membership: 
SELECT: aspnet_Membership_GetUserByUserId
INSERT: aspnet_Membership_CreateUser
UPDATE: aspnet_Membership_UpdateUser
DELETE: aspnet_Users_DeleteUser
If I would have used SQL Statements I could have created a subquery for CRUD from UserInformation. Does someone know how I can use stored procedures to Select, update, insert, delete (CRUD) from these two tables? 
Or should I be doing this somehow differently?

DataSet Confusion
I am new to the DataSet-DataTable-TableAdapter concept.  I am using the Working with Data in ASP.NET 2.0 tutorial to assist in learning.  Here is my confusion:
I have tables in SQL Server 2000 and I use Stored procedures for all the CRUD operations on the tables.  Say I have a table with the following fields:
CustomerID - int, CSRID - int, PartNumber - varchar(25), Reason - varchar(200)
All of these fields - except Reason - are foreign keys to other tables.  So I can include CustomerName and CustomerPhone in a query by joining on CustomerID.  PartNumber can be used to get PartWidth, PartLength, PartDescription.
When you initially create the DataSet with the configuration wizard, do you need to include ALL possible fields you might want to use in the SELECT operation? 
I know you can add more TableAdapters, but if you use a query that contains fields outside the DataTable, this causes problems.

At the moment I gave a function (GetProfile) which returns a dataset (dSet) something like this
Dim dataAdapter As System.Data.SqlClient.SqlDataAdapter = New System.Data.SqlClient.SqlDataAdapter(sqlCommand)Dim dSet As System.Data.DataSet = New System.Data.DataSetdataAdapter.Fill(dSet)
return dSet
I am using the .Tables  property of the dataset to loop round the values. like this (below), I can't use the SQLDataSource control to bind to a form or controls due to the functionality of what I'm doing.
    Dim dataSet As System.Data.DataSet = GetProfile(UserID)    With dataSet      If .Tables(0).Rows.Count = 1 Then        With .Tables(0).Rows(0)
                  (some code like)
            lblName.Text = .Item("Name").ToString            Page.Title = "Member profile::" & lblName.Text 
               End With
            End If
         End With
So my question: is there a way of using an SQLDataSource control to populate a dataset rather than using my function?

DataSet To SQL Script?

Does anyone have a way to generate a SQL 2000 database generation script from a DataSet? I'm looking to load an XML file into a DataSet and use it to create the db design.

Dataset In SqlDataSource
Probably some simple question but I'm struggling with this one:How can I retrieve the dataset from the SqlDataSource? I would like to just place a SqlDataSource control on my webform and then bind several items (column/row) to a Label or TextBox.
