I tried this post in another forum, but thought maybe someone here can help me out.
I am having trouble selecting data from an access table. I can select from other tables in the database, but not one named "GENERAL". Is this table name a problem and do I have to qualify it somehow? When I run the code I get an error.
ErrorCode=-2147217900
Message="Syntax error in FROM clause."
Source="Microsoft JET Database Engine"
Error Item is: "In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user.
I have searched and found a non-existent table may cause this error. I know the table exists because I can open it in Access. I am using the following VB.net code that works just fine if I substitute another table name for GENERAL. I also tried qualifying the field names with "GENERAL.", but that didn't help either.
Just found something else. There is a "+" to the left of the record when viewing the file in Access. Clicking on the "+" sign displays some related records below the record. Is this stopping me from reading the file from VB.net? Is there a way around this?

Code:

SelString = "Select TD From General"
' Connection & Command Setup
Dim myConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = C:\Program Files\GIS Viewer\Database\Viewer.mdb"

Dim myCommand As OleDb.OleDbCommand = New OleDb.OleDbCommand(SelString, myAccessConn)
myCommand.CommandType = CommandType.Text
' Get Data
Dim myDataSet As DataSet = New DataSet
Dim mySqlAdapter As New OleDb.OleDbDataAdapter(myCommand)
mySqlAdapter.Fill(myDataSet)
MessageBox.Show(myDataSet.Tables(0).Rows.Count.ToString)
Dim nn As Integer = 0
While nn < 10
MessageBox.Show(myDataSet.Tables(0).Rows(nn).Item("TD").ToString)
nn = nn + 1
End While
' Clean Up
If Not (mySqlAdapter Is Nothing) Then
mySqlAdapter.Dispose()
mySqlAdapter = Nothing
End If
If Not (myCommand Is Nothing) Then
myCommand.Dispose()
myCommand = Nothing
End If
If Not (myAccessConn Is Nothing) Then
If myAccessConn.State = ConnectionState.Open Then
myAccessConn.Close()
End If
