DB/Reporting :: Can't Select Column Names With Spaces
Apr 7, 2012
I'm just a frustrated noob trying to get past my first DB Program. My goal is to get relational data from different tables all ordered by a certain field..Ive noticed early on that i cannot select a column when its name has a space.[code]Now the statement i want to use is sql = "SELECT [PT.Chart Number],[PT.Last Name],[CA.Case Number] FROM Table1 AS PT INNER JOIN Table2 AS CA ON PT.Chart Number = CA.Chart Number ORDER BY PT.Chart Number"..When i Debug i get the same type of error ("... Can't find column name PT.Chart... ")I'm new to sql so i dont know if my syntax is off.

[code]....
I have edited the column headers and set the column names to the same values as my table names yet the data is not showing in form load I have set datagridview.AutoGenerateColumns = False I know the data is there if I delete datagridview.AutoGenerateColumns = False then the data is shown with the default headings?

I have a question about Select Case. My code (psuedocode) is this
[Select Case name
Case number
name=Remove(num, 1, " ") ]
What this needs to do is to remove spaces at the end of a number and lets say that the number would look like this "C12345" but what I want is for the number to look like this "12345". I have it as a hyperlike but for some reason when at the link in the code it had added some spaces at the end of the number and I do not know why. What I want to have happen is when the hyperlink is click that it will go right to that number but it does not. When you click it you have to go to the top of the page (where the http is at) to to the end of the link and back space. Once you have done that it will go to the page that you want.

I have tried:
ObjDTOleDBNFeIntegra.Rows(I)("[Cnpj Cpf]").ToString() //with brackets
ObjDTOleDBNFeIntegra.Rows(I)("'Cnpj Cpf'").ToString() //with apostrophe
ObjDTOleDBNFeIntegra.Rows(I)("Cnpj Cpf").ToString() //without anything
I'm using VB.NET, but comments with apostrophes in here don't seem to be identified.And I get the exceptions for each case:
Column '[Cnpj Cpf]' does not belong to table Table. (fail)
Column 'Cnpj Cpf' does not belong to table Table. (fail)
Column ''Cnpj Cpf'' does not belong to table Table. (fail)
What should I do in order to ger a value from a field in a dataTable when the column name has spaces ?

I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from [URL]. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from [URL]
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...
My.Computer.FileSystem.RenameFile("Test Flowchart1.dwg", "Test~Flowchart1.dwg")
It's the same problem for all of my File System commands. Either file not found or invalid arguments.
The complete script I'm using is here:
Sub Main()
Dim arrArgs() As String = Command.Split(","), _
i As Integer, folderPath As String, myPart As String, _
[Code].....

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 just changed a control on a form from a masked textbox to a normal textbox because I wrote my own code to validate the data. I'm trying to clear the leading spaces that were created for this column in an Access database using the LTrim function and it doesn't work for some reason. The column is " :30" in the table and when I LTrim it and save the changes, it's still " :30" , not ":30". Is that leading entry not a space character?

The name "Debit" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted.

I have the following code to get the column names from my Microsoft Access database.THE PROBLEM is that the stupid thing orders it alphabetically for me. How do I get it to put the columns in order the way they are in the database?[code]I've also tried a different approach with a string array and for loop to "make it" go to the beginning, but proves my point that its stupid enough to order it for me.

I have to create a report that lists tests that a student has taken and how they answered each question...the column header layout (roughly) looks like:
Test #1 1 2 3 4 5 Test #2 1 2 3 4 5
TestA A B C D E TestB C C B C E
The problem is that the Gridview doesn't seem to like repetitive column names and is renaming the second set of Question #s to something else.

I have a table in a Access Database that I'm loading into a VB.NET program and I want a way to get the name of each of the columns into a list of Strings. Googling has shown that this is much easier with a SQL database, but that doing so in Access is much more difficult. I came across this question Is there a query that will return all of the column names in a Microsoft Access table? Which gives a way to do it, but when I try the code it just populates my list with a bunch of "System.Collections.Generic.List'1[System.String]"
This is my adapted code.
Public Function GetColumns(ByRef database As String, ByRef table_name As String, ByRef columns As List(Of String)) As Integer
Dim com As OleDbConnection
Try
com = New OleDbConnection(database)
com.Open()
[Code] .....
My for each loop isn't printing the right string. Should be Console.WriteLine(holding)

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)
