Sql - ADO.Net Not Recognizing Column In Select Statement
Oct 7, 2009
I have a query that executes fine in TOAD, but when bringing back the results with either an ADO.Net DataReader or DataAdapter/DataSet, it's not recognizing a column in the select statement. See the query below... the column in question has its data coming from a dynamic table or sub-select or whatever you call it. I don't see why this is a problem in .Net:
Dim sql As String = String.Format("select bu.row_id, bu.name, selectedOrgs.bu_id as selectedOrg " _
& " FROM SIEBEL.s_prod_int_bu pb " _
[Code].....

i have a problem with a SELECT statement.I have a table <EisagogiStoixeion> with 6 columns, one of then is < AgonPeriodos>. I want to display data in a datagridview depending on the column <AgonPeriodos>. I use the Select statement like this :
SELECT * from EisagogiStoixeion where AgonPeriodos = '" & textbox1.text &"'.
Value not set for one or more required parameters. This is my problem on the fill command.
If i don't use the where statement everything is ok and i can see the data including the data from the AgonPeriodos column.

I am using OleDb, trying to do this:
Dim d as Date = DateSerial(Year(rptDate), Month(rptDate), 1 - 1)
Dim conn as OleDbConnection = new OleDbConnection(connStr)
Dim cm as OleDbCommand = new OleDbCommand()
[code]....
I know that d is the same date as the one in SQL server, specifically 3/31/2011 12:00:00 AM.

Explain why this is not possible.

X = 0
ElseIf population > 1000 Then
X = 1
ElseIf rate < .1 Then
X = -1
End If

I need to use a SELECT statement to select all data under a column name (like all employee names) and then to add the values to a listbox.
I usderstand that the select statement must be:
"SELECT * FROM EmployeeTable WHERE EmployeeNames LIKE *" (at least I think)
but then what? combobox1.fill ("EmployeesTable") ?

I'm writing a help application for the Customer support team at my company to help agents ask better questions when customers report problems. In it, I've got a SQL database that contains all the products, topics, and questions. The layout is similar to the following:
Products Table:
Product_ID Product Name:
Topics Table:
Topic_ID Product_ID Topic
[code]....
I don't know if I'm making myself clear, but I basically need to do the equivalent to the following SQL statement: "SELECT PRODUCT_ID FROM Products WHERE PRODUCT_Name = LstProducts.SelectedValue"

I have a datatable and I would like to get the MAX number from this table where Term Number (first Column) is a certain value. If my datatable is declared as dtMyTable, I'm assuming I need to use dtMyTable.Select(), but I'm not sure if this is the best way.

I am tryin to access a 2003 Microsoft Access Database using VB in an OleDb format. The database file name is Billings.mdb and there are 3 tables in the file the one I am trying to access is tbl Clients. When debugging the program I continue to get an Unhandled error point to the FROM part of the SELECT statement. It continues to occur regardless of my attempts to vary the input.
In the program my connection statement is as follows:
Dim connectionString As String = "Provider = Microsoft.Jet.OleDb.4.0; Data Source = C:Documents and SettingsTrialsBillings.mdb"
The Select statement is as follows:
Dim selectStatement As String = "SELECT ID, ..., PB " & "FROM tbl_Clients " & "WHERE ID = ?sngID"

I just replaced a different segment of code with the select case statement and it works fine. However I don't understand what the dim is for after you do "Select case [variable name here]"
I currently just dimmed a value as nothing. I didn't specify any data type for my variable I'm using for this case statement. But it works.[code]...

I am using vb.net 2005. I am trying to select data from a table where the field [hoteldate] is 2 days from now. The field's format is MM/dd/YYYY and when I use the Where clause :WHERE HOTELDATE = DATEADD([DAY], 2, GETDATE()) it returns nothing. I am assuming it's because the getdate() function returns something like 2012-24-02 T blah blah. How do I convert so I can get a match? I've tried several things including converting do a

I was using an If block to see if a line in a file contained a specific string. But I need to look for many different string and do different things based on each. So I don't want a million nested If blocks. So I decided to use a Select statement. But, I can't figure out how to use .Contains with it. If I do .ToLower.Contains, like I did in the If block, it stops me.

Also, I'd like dgMarksEntry.Item(7, i).Value and dgMarksEntry.Item(8, i).Value to handle RANK and COUNT the number of items entered respectively. [Code]
