VS 2008 Multiple Tables In Single Dataset?

Apr 6, 2012

I am a new user. Apologies if I am posting this in wrong place and also if it is repeated one. I have few queries:

1.Is it possible to store multiple tables in a single DataSet?

2.If yes then it is a good practice? or should i prefer having separate connection object, separate DataAdapter and separate DataSet for each of the table to be accessed? I am new to VB.NET and using VB.NET 2008 Express and MS-Access 2007 as backend for my project.

How to Query multiple tables in a dataset to form single consolidated table without using any external database. I know this can be done using 'JOIN' in SQl.

MySQL Update Dataset With Multiple Tables - Close?

Nov 7, 2010

I've been working with a remote mysql database. The design of the database pretty much requires that I use SELECT commands that include multiple tables, and sometimes joins. Updating a single table query is SO EASY, yet dealing with multiple tables has me pulling my hair out.

[Code]...

What's killing me is that if I make a change to a field in the products table in the datagridview and press button1, the changes are saved. If I make a change to a field in the specials table in the datagridview and press button2, the changes are saved. If I combine the two updates together in a single routine, only the first one is saved. I presume this is because after the first update executes, the dataadapter no longer reports that there are any changes to save, since the update already happened.

I've tried breaking this up into separate dataadapters for each table, but then even using dataset relations, I can't get the data together in a single datagridview. On top of that, the grid itself is only intended to be used for searching and querying data. It still needs to be bound along with a set of textboxes that accept the input.

Lastly, this database is part of an ever-evolving website database with dozens of tables that need interfacing. I just can't see manually maintaining hand written sql statements for every table. That's why I've been working so hard to get the commandbuilder to handle it.

VS 2010 Add To The Tables In A Dataset?

Apr 13, 2012

I am working on a database application. I had used Dataset to link my VB programme to a database and selected specific tables. However, I created more tables in the database and I wanted to add the new tables to the dataset. I could not find a simple way to do this, so I deleted the existing dataset and created a new one. This move has broken my VB codes. I can no longer run them as errors are shooting up. In fact, I connot view the forms in my programme anymore. I have a backup of the codes to rerun, but then I need to add new tables to the dataset.

Multiple Tables In Visual Studio 2010 (VB) On Data Grids

Feb 13, 2011

I have looked at the answers in the forum and some seem dated. I an an old vb2 person and need to move up. I understand sql very well and use complex queries. First test project and trying to add multiple tables to a data grid (Only Form in project).I used the Data wizard to add the Access data base and worked by way through to near the end. The query works in the wizard and returns the correct rows. The error message is "The solution returned by the new query differs from the base query."

During the creation process I selected all the tables. Reading some of the old anwsers I get the inpression that VB 2010 does not handle multiple tables in a datagrid (forum items go back to version 2008).

SQL Performance Timeouts - Adding Multiple Rows In Multiple Tables In The Database

Sep 12, 2011

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

Populate Tables In A Dataset?

Oct 12, 2011

I have need for a database in my latest app, i quickly realised it had been a long time since i last used a database and am in fact very very rusty on the subject. So i decided to create a simple DataSet using the designer, i created 2 tables as follows

Table 1 is Named Map and contains a 2 dimensional array each cell containing an array of object id's of anything in that cell, and a level ID.

Table 2 contains data about these objects ie size weight and a z-order, again referenced by an object id (matching Table1)

This i did with no issues, when it came however to actually populating these tables i drew a blank. Do i have to locate the database file and edit with notepad? I presume not. Maybe i have to use an external app like sqlmanager? I seem to recall from my past that i added table rows from within the designer but i cannot find this in 2010 express

.net - Combine Multiple Dataset Columns To One Dataset?

May 19, 2010

I have multiple datasets that I would like to combine into one. There is a common ID field that can be associated to each row. Calling Merge on the dataset will add additional rows to the dataset, but I would like to combine the additional columns. There are too many fields to do this in one query and therefore would make it unmanageable. Each individual query would be able to handle ordering to ensure the data is placed in the correct row.

For Example lets say I have two queries resulting in two datasets:

SELECT ID, colA, colB
SELECT colC, colD

The resulting dataset would look like

ID colA colB colC colD
1 a b c d
2 e f g h

Dataset Tables Missing From Xml Input?

Nov 3, 2010

I build xml in memory from the file, separate that into nodes for binding to different grids, works fine except the dataset is missing two tables and I can't find out why, the code below uses a stream but I've tried a ton of stuff by now, and, just using ds.ReadXml(path) doesn't work to get the proper nodes and drops all but the first major node: vs2008/vb.net project.

I believe what's going on is that the nodes have attributes ... none of the nodes that do come through have them, the "author" and "entrydate" nodes are being dropped from the string:

If (My.Computer.FileSystem.FileExists(pPath)) Then
xmlDom.xmlArchMaster(pPath, xml)
_default.ActiveSiteID = xmlDom.siteheaderNode.Attributes("id").Value

Forms :: How To Create DataSet And Tables From XML

Aug 4, 2011

I have an XML file that has a basic hierarchical structure about horse racing. It has a summary of the tracks, some data about each track, then a list of all the races at each track racing that day. So lets say there are 10 tracks, and for each track there are 8 races. This is a snapshot of the data....

HTML
-<Meetings xmlns="" Jurisdiction="VIC">
-<Summary MID="MR_20110801">
<VenueName>ECHUCA (VIC)</VenueName>
<Type>R</Type>
<Events>10</Events>
<Track>DEAD </Track>
[Code] ......

I have written the code to pull down the data into a data store, but I dont know the BEST way to put the data into a set of tables. My first thought was to traverse the nodes and add rows into tables but I figure there must be a native VB process that reads the xml and puts it into the the appropriate table. How to code up the process for getting the data into a set of tables that match the xml. So lets say I have a Summary table, I would like all the data about each track to go into that table. Then I would have a Races table and have the data for each race go into that. What I have done already is import the xml into Access to create the tables (which was a breeze!) and then link that data source to my project. So I have the tables already built.
