how to select multiple table in vb2010? i trying to create a login so i need to retrieve the data in 3 different tables in one database i have a code but not work.[code]
For my app users can enter a SELECT statement themselves. This can be any select statement at all, it will be mainly used for creating a quick view e.g. SELECT * from table1 LEFT OUTER JOIN table2 on table1.id = table2.id.
Whatever this select statement maybe I load it into a datatable (after checking for no nasty stuff of course) in vb.net. I want to know the table names so I can query the database again for validation purposes on things like datatypes etc.
da.SelectCommand = New SqlCommand(sqlStatement, tempDB.Connection) da.MissingSchemaAction = MissingSchemaAction.AddWithKey dt = New DataTable da.Fill(dt)

I have two tables Employees and CafeLogs. Some employees can be cashiers and also customers at the Cafe shop.
Table structures:
Employees: EmployeeId(PK) , FirstName, LastName CafeLogs: LogId (PK), CashierId, EmployeeId, Value, => CashierId and EmployeeId are the data from column EmployeeId of Empoyee table
Table relationship:
Employees 1:N CafeLogs (CashierId (FK))
[code]....
Right now I know how to select only LogId, Employee's name, and , Value, not with Cashier name yet.
Dim query = From log In db.CafeLogs _ Join emp In db.Employees On emp.EmployeeId Equals log.EmployeeId _ Select log.LogId, emp.FirsName, emp.LastName, log.Value
I 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?

I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.

I have problem and I've been looking for a week now on how to solve it. Yesterday I thought I solved but apparently I didn't when I tried the query with new data added in my database.Here's my query
Public Function getTicketsByBeginstation(ByVal station As String) As Array Dim r As Array r = (From u In treinDataContext.Tickets Where u.ritId =[code].....
The problem I have is: when I have a station selected there are more than 1 trajecten (connections in English) but I had to use the .first else Visual Studio would give the error "the '=' operator is not defined for 'integers' and 'system.linq. IQueryable(of integer)".
So I give the name of a station -> I have to select all trajectens with the given station as beginstation -> I have to select all ritten which have the given trajecten -> I have to select all tickets which have the given ritten So: I have to show all tickets for a certain station.

I will post a sequence of examples and thought about sql injection, I wish the expert will correct any small mistake in what I will say so I can know exactly the possible danger.
The required is to create a function in vb.net that accept 2 parameter (table_name, fields_list) and return the result in datatable
Now, I am aware of that table_name and fields_list cannot be passed as parameter to the command object using .AddParameter
here is a couple of thoughts, what I would like to know is
1- which function is exposed to sql injection
2- Which function is more safe
Public Class Form14 Dim conn as New SqlClient.SqlConnection(connection_string) Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I have a program that I wrote that creates a database in SQL Server called States_02 as a sysadmin user. Later on I want to grant SELECT permissions to that database to another user, web I always get an error that it cannot find States_02 or I don't have permissions to do it. My Code:
Dim Conn As New OleDbConnection(ConnStr) Try Conn.Open()
[Code].....
The user has public and sysadmin server roles and is the same user who created the database. This user can also login to SQL Server and grant the permissions manually.
