Returning Multiple Datasets From A Stored Process
Jan 19, 2010
I have an encrypted SQL Server stored proc that I run with (or the vb .net equivalent code of):[code]this returns 2 datasets and the output parameters for the results, the datasets are made up of various table joins etc, one holds the header record and one the detail records.I need to get the 2 datasets into a structure in VB .net (e.g. linq, sqldatareader, typed datasets) so that I can code with them, I don't know what tables any of this comes from and there are alot of them Whooopeee...I came close using Linq to SQL and IMultipleResults but got frustrated when I had to recode it every time I made a change to the designer file.

I already know how to call insert, update, delete & select procedures in DataSet.xsd window. And I also know how to call queries by table adapters. But I just found out that its not possible to call all functions by queries (such as insert). It works when I test the query but when I try to add it, it says "Failed to get schema for this query". So I built a few stored procedures which do many functions (such as transaction, insert, update etc...). But I am unable to use these stored procedures in VB form. I found some tutorials mentioning that it can be done by defining connections and some other stuffs with which I don't want this to be. I want to call these procedures by writing code in VB code editor window with DataSets, TableAdapters, BindingSource etc...

I am posting this here because the sql query seems to be fine, it is the VB code that is the issue. I am new to VB and I have a subroutine that imports a value for the strating and ending time of a report. The error I am getting is: Conversion failed when converting the varchar value 'Aug 20 2009 12:00PM' to data type int. Here is the code for both VB and SQL:

This problem has driven me mad for over a day now. I can create a connection to the database, I can execute sql and return results from that but I can't seem to call a stored Procedure. Here is the code
[Code]...
it works ok but no results are returned. I've verified that the procedure returns results for the user I'm logged in as. When the query was executing I could see a refcursor in there but it was empty. I must be going mad.

I have a report where I need the same data, but for four separate date ranges. Currently this data is based on one month, so it's just one dataset. But now I am trying to do this with four separate datasets, where each one is filtered on each of the four date ranges. I setup my WHILE loop to loop thru all four dates. But I'm having trouble now with distinct naming these datasets. Is this the best way to do this? It looks like if I used multiple datatables for one dataset, I'd have to define each datatable column. Here is my current dataset commandstring

I have a dilemma. The program I"m trying to complete is one VB project with three (3) forms. The first form will act as a menu dialog box. The other two forms will have a dataset (database) on each form. The first form will have a button when clicked it will pull up form 2 and the second button when clicked will bring up form 3. What I add the dataset to form 2 everything is fine. I can see my tableadapter, dataset and so on. Now, when I add the second dataset (database) to form 3, I loose my, dataset and so on. It doesn't appear on any of the two forms (in designer)tableadapter.

Im currently making a program. It loads data from database fields into an combo box. Everything works so far, It just seems to be a mess. Do i need to have all the datasets and data adapters? or can i get away with just using 1 of each. It seems like im doing it wrong, and although it works it seems like a difficult and messy way of doing it.
Also i would like to assign the firshermenID to a variable depending on the fisherman name that is selected in the combo box. When button is pressed: id = fishermanID of the current fisherman (cmbFisherman.text)

I have a form with multiple DataSets (filled by multiple Stored Procedures) and corresponding DataAdapters. Associated with the DataApters are commands for UPDATE, INSERT......... Before using the DA Update I am using 'If DSxyz.HasChanges(). It seems that when I make a change anywhere on the form affecting 1 dataset, all of the datasets show this to be true. Why should changing one dataset on a form cause all of the datasets to show changes?

I am working on a project I would like to use a function in a class I created to return multiple values in order to populate a listbox. I wanted to use a do until loop to achieve this. I will just post a simplified example of what I am doing :
Public Function Listboxfiller
Dim astring As String = "This is a string"
Dim Counter as integer = 0
Do until Counter = 5
return astring
Counter += 1
Loop
Then on the form I would do something like :
lstListbox.Items.Add(Myclass.Listboxfiller)
What happens right now is that the listbox only gets the first value, when I ran through in debug mode I found the loop only runs once, even though it should go multiple times.

I am struggling here with introducing web services into a site I am currently working on. The background is as follows.
- I have a page switchboard.vb which will recieves incoming xml requests.
- I parse these xml requests extracting its values, then setting them equal to the relevant global variables in switchboard.vb.
- One of these variables will determine a 'requestType'. Based on this requestType I want the page to call particular web services that I will add.
- These web services will then validate the user calling has permissions to access and execute it.
- The switchboard.vb page will then generate an xml respose which will post to the client.
Here is a summary of the process
getXML()
parseXML()
determineRequestType()
executeRequest()
rebuildXML()
postXML()
The ways I can see to do this are:
1. Pass the variables into the required Function allowing it to pass back a pre formatted xml string.
Pro: Simple
Con: It is not really using the web service as it should be.
2. Pass the variables into the required Function as 'ByRef' values hense changing the original value on switchboard.vb
Pro: allows me to format the outgoing xml on switchboard.vb and gives me more functionality with more individual variables as opposed to one string being passed back.
Con: Is this taking advantage of a web service? When I tried this the web service form didnt give options to input test data. Possibly because I am using ByRef?

I have a table with several rows of data that I need to return to the controller. In my view, I initially load the table by selection of a time period and clicking a button. The table loads all my relevant records but one of my table cells contains a dropdown list. So I should be able make a selection in the dropdown click "update" and my controller saves the changes.
So everything works until I try and save. The model that is sent to the controller is completely null. The list property I have tied to the table cells returns to the controller null.

I am using this vb.net code file to call a procedure to get dates (among other things). When I execute this procedure in SQL 2005 Server Management Studio, I get about 10 columns. However when I execute this code, the dataset seems to only have one index value, maybe I am misunderstanding something. When I change this
ds.Tables(0).Rows.Count.ToString
to
ds.Tables(1).Rows.Count.ToString <---changing the index value to 1
(or higher)
I get no information. So my question is;
Does the DataSet contain the other columns, only not indexed like an array? What I want to do is choose which of the columns to filter out and turn the rest into JSON formatted strings.

i've done some basic parsing with text files before.
Scenario is i have 4 textboxes String (which contains the string i'm wanting to parse) sub1, sub2, and sub3. so the string is ex. 500000-1-2
- is the char that is the seperator
so the aim here is to get
500000 into sub1
1 into sub2
2 into sub3
the real string i'm wanting to parse is much more complex, but i'm keeping it simple here for a jumping off point so i can figure the rest out.

I'm creating a database installer where I have some code to create database, tables, stored procedures, etc.I don't have problems when creating the database, tables and inserting required data. My problem is when my code gets to the stored procedures section.
Here is what I do:I have different text files (database.txt, tables.txt, insertdata.txt, storeprocedures.txt) where my sql syntax is located.I execute every process/text file using the following:
ExecuteSql("master", GetSql("database.txt")) ' Creating 1 database.
ExecuteSql("mynewdatabase", GetSql("tables.txt")) ' Creating 15 tables.
ExecuteSql("mynewdatabase", GetSql("insertdata.txt")) ' Inserting data to many tables.
ExecuteSql("mynewdatabase", GetSql("storeprocedures.txt")) ' Creating 6 stored procedures.
Here is part of the error:In exception handler: Incorrect syntax near the keyword 'PROCEDURE'. "This is the second stored procedure because the variables I get below belong to the second one"
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
When trying to create 6 or even 2 stored procedures using the same file 'storeprocedures.txt' is not possible. If I leave just 1 it works but I really want to keep them together.
Creating 15 tables using the same file 'tables.txt' works, inserting data in different tables using the same file 'insertdata.txt' works.This is the general syntax I use:
Create Procedure sp_stored1
@intVariablex int
As
[code].....
Is is possible to create more than 1 stored procedure the way I'm trying to?Do I need to end every stored procedure with specific sql syntax, other than the 'end'?

I have a form which displays related data from three different tables. There is a foreign key between the master table and the two related. Currently I have three stored procedures to return the data based of the return key value from a search becuause I am using DataAdapters to select and modified the recordsets. This works great, but I'm sure adds a lot of overhead. In VB 2008 with SQL 2008, is there a way I could use only one stored procedure to accomplish this?
