Retrieving Data From An Excel Sheet Using A Simple SQL Query?
Jun 11, 2011
I'm retrieving data from an Excel sheet, using a simple SQL query using a textbox as input to my variable. It works great when I enter an integer to search for (such as 213 for example) but when I put in a mixture of numbers and letters (48A for example) I get the following error: Syntax error (missing operator) in query expression '[P&L]=48A'.
Private Sub MPLS3()
Dim BrNr As String
BrNr = TextBox1.Text
Dim stSQL As String = "SELECT [MPLS Date] FROM [Master Data$] WHERE [P&L]=" & BrNr & ";"

to setup daily import of data from excel file into SQL database - preferrably through Visual Studio project (Visual Basic 2008). The problem is that I wouldn't know the name of the excel sheet.

I am trying to read data from an excel sheet but there is an exception saying that no value given for one or more required parameters which I don't understand. Here is my code upto where the error is pointing to:
Dim MyConnection As System.Data.OleDb.OleDbConnection Dim DtSet As System.Data.DataSet Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The exception points to that last line MyCommand.Fill(DtSet) which shows me that there is a problem with my select statement. Previously my code reads the data and displays it without the where clause in the select but when I added the where statement so that it can only read data from rows where the column I has a value equal to 176, it instead gives an exception that shows that some required parameter is missing a value?

So I've got this Excel sheet of employees which have all the information about them. I'm trying to import this info into AD, but in order to do that I need to get the username for these users as well. And I would like vba code or vb.net code that basically takes the value of every row in column D and looks for it in AD and returns the username and adds it to column A. Would something like this be possible?
