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.
Now my condition is I have multiple tables filled with data in a dataset and each table is interrelated with a common 'column'. For example ,
Table 1 ID Name 1
[Code].....
Here I mentioned only two tables but in my case there are many tables. I need a generic answer for this dynamic query .
I cannot seem to figure out how to search through a created/filled dataset for a certain value which exists in column(1), returning Column(0)'s value into a textbox.My code looks like this:
So I'm not familiar with much vb code but I was hoping someone my spell out something pretty generic as far as updating a database. I'm pretty sure I've successfully edited rows but when i'm using my database update i get an error, probably just incorrect syntax. This is what I have so far...
I have a form in vb8 that is set up as follows: I have a table in my Access database calledUsers that has a name and a password (encrypted). Using the toolbar I created aBindingSource with a name of UsersBindingSource and a dataSource ofUsers Using the toolbar I created aDataset called with a Name and a DatasetName called Users_Dataset Using the toolbar I created atableAdapter called UsersTableAdapter I added two textboxes on the form and changed theirDatabindings...Text property to the corresponding field in the Database.
How to now update the database when I click Update. What the program needs to do first is encrypt the Password before saving it. I wrote the code in the TextBox2.Lostfocus event to encrypt the data a place it back into the TestBox2 field. The only samples I find on the net refer to DataGridView controls (which work) but I don't want to use them. How can I get the database to accept these changes as well as changes to radio buttons or comboboxes?
On a form i have several text boxes binded to a bindingsource and including a datagridviewI have populated the textboxes with database fields successfully and the datagridview displays the correct information.I have the following code to save the information to the database but i cannot get it to work. [code] I have tried many code examples here in order to save the data, none of which has worked.Can anyone please help me with this?
i'm using vb 2008 express editor, and 3.5 compact sql, through my program, i make changes, like altering rows, deleting or adding new rows, to a dataset. i want, that when button 1 is pressed, all changes made to that dataset, are updated to my database. what is the line of code that does this? [Code]
I am developing an application which uses a database that holds the information about a company and it's personnel. but when I try to edit already existing data in the dataset it just won't update it. I've tried all the method the MS sites provided me, but it just won't. the code looks like this: (notice this code wasn't complete)
AddNodesTableRows As SampleDatabaseDataSet.NodesRow Dim i As Integer For i = 0 To 10 AddNodesTableRows = SampleDatabaseDataSet.Nodes.NewNodesRow()
[code]....
End Try I've get no errors or exceptions from this code but it will not put the data into the database file. It always run through the "update successfull" yet nothing is ever written out to the file.
I am popolating a DataGridView with a DataSet from an SQL database like in example bellow.
After I am making some changes I need to know how can I save modified data in SQL database>
Let's say that I have a form with a DGV and a button. On load I will put ten lines from a tbale from database inside the DGV. Then i will make some changes and after that when I click on the button I need to save the modified information. Everything has to be done on runtime.
I have written the following stored procedure: ALTER PROCEDURE ProcGet Add the parameters for the stored procedure here @id as int output, @name as varchar(50) output ASBEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
I am using vb2008 express edition and SQL Server 2000What I am trying to do is programmically populate a dataset with records from a database and then bind the fields to textbox controls so that and changes will be updated in the dataset and eventually the database.I have managed to get as far as displaying the data in a form, but cannot understand how to update the database when a button is clicked.
I am currently developing an application that is linked to a MS SQL Server 2008 Database. So now I realised that I needed to make a few minor changes to the database (add new columns to some tables, change the data type of a few columsn in some tables). After making the changes, I realised that these changes have not been updated in my VB application's dataset. I then tried to "refresh" the dataset, but it still is not updating the dataset. What do I need to do to update the dataset to reflect the changes in the database?
I'm developing an application where depending on a textfile input i should update/insert some data into an Access database. Let;s say I'm updating the bookshelf of a book according to a textfile that goes like:
TEXTBOOK | BOOKSHELF 000000001 | 000000000A and so on
[Code]....
does that make any sense? What I'm trying to do is basicalle: check if a book exists, if yes, then attach to Dataset, change its Bookshelf to the one in the textfile and repeat until the file is completely read. The Bookshelf can or not exists, if it doesn't then it should be inserted, is it done automatically when I update the Dataset? Finally "Batch update" the whole Dataset.
I'm fairly new to visual basic and have a problem that is probably quite easy to solve yet I have been unable to do it so far and am about at wits end.I have an access database with a table that contains a list of cities and states. what i would like to do is to populate a combo box on a vb form with a list of the states in the states column. the query that i have is as follows:
SELECT DISTINCT State from Cities I have previewed the data in the dataset designer and it works, i just can't figure out how to make it fill the combo box. i initially created a table with just all of the states and then used a binding source and table adapter to bind it to the combo box, but if I'm able to figure this out this would help with my application going forward
I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.
Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.
I wrote the sql update function in the service:
Code Snippet from web service
<WebMethod()> _ Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)
[Code]....
This displays the records perfectly and I figured out how to delete and insert records via web service.
writing updates from the datagridview back to the database.
I am writing a small windows client application that accesses data using a web service that returns datasets.When the dataset is returned, a datagridview's datasource is set to the dataset.
My question is, how do I write changes that were made in the datagridview back to the dataset and then back to the remote database.
[Code]...
Now the client snippet that connects to the service and lists the equipment
I want to save data that I have typed into a datagridview column. The datagrid view is filled from a simple query. I can save when in access but not when I want to from a screen using vb2008. hat do I need to do?
I have a gridview loaded with data from my database and a gridview swapping function which after exchanging data between rows with a column call "Priority", I want to save these changes back to my database. Only the "Priority" column value will be change, how do I update only that Column of my dataset table to my SQL database?
I have an application that performs database queries using "Imports System.Data.SqlClient". I want to display an animated GIF on the taskbar which spins while the query is running. However, during a query the application simply hangs and does not update the GUI until the query has finished, at which point the spinning icon is set to invisible anyway. Is there any way to force the GUI to update while the query runs?
I am new to ado.net and I am trying to learn capabilities as much as get this particular task done.Let me set the stage for my question.My goal is to load up a dataset, write out an XML, transfer the file to another machine, read the XML back into a data set, load up the local tables, find missing records from the local database and add them.These tables are for employees. There is the 'Employee' master, "Employee Job" the employee job code, and "Employee Hours", the employee time punches.I thought I could treat a dataset as a database and do SQL queries against it.For example to find missing Employee , my thought was to do a outer join on employeeID and look for null in the second table.Something like:
i think i have not represented my question correctly here My LEFT OUTER JOIN MSDN reference is here to visualize my problem in access databaseTABLE "T1"1234567TABLE "T2"1,sunday2,monday i need output as 1,sunday2,monday34567 i need it to done through LINQso far i did is here
Dim RIGHT_table As DataTable = ds1.Tables("t1") Dim LEFT_table As DataTable = ds2.Tables("T2") Dim OutPut = From LEFTsource In LEFT_table.AsEnumerable(), RIGHTsource In RIGHT_table.AsEnumerable() _
I have this query that I tried to join 2 tables together, one which holds the product name, and product numbers, and take a product number, and go to the other where to find a Art_no which is like the product number.[code]

I would like to list all of the job titles(for which there could be multiples as different employees can have the same job title) in the employee table and find the maximum amount of hours for that job title as the hours could be different for different empoyees.
I have been searching for quite a while about joining multiple datatables via LINQ to dataset (When i say multiple, i don't mean just 2!!!), and it seems there aren't lot of examples in the net. I have seen examples of joining two datatables, done that, no problem there. Now i want to join three datatables. And there's nothing i can find out there.For example i have a 3 datatables:
i am having 2 tables one table stores the WEEK-days another table stores the WEEK-days + other fields.i need the LINQ query to return all WEEK-days + other fields just like SQL LEFT JOIN query so far i did is [code]....
The query works but only retrieve the joined rows, i want to retrieve all rows in the first datatable.My current query:
vb.net Dim q = From regE In (From registoE In _dtRegistosAEnviar.AsEnumerable Group registoE By colaborador = registoE.Field(Of String)("Colaborador") Into grupoE = Group Select New With {
