ever time i call this function in vb.net

' checks to see if user is able to read data on that form
Public Function hasReadAccess(ByVal formName As String) As Boolean
Dim cmdGetPermissions As New OleDb.OleDbCommand("SELECT read from
userformaccess where userName = 'default' and formname = 'directory'")

cmdGetPermissions.Connection = dbConnection

dbConnection.Open()
End If
gotValue = cmdGetPermissions.ExecuteScalar()

why is it giving me that error? the table its pulling from is set up like
this in access, all my other db commands work but this one... whats wrong
with it? the select statement works in access with no problem at all

userFormAccess table
=================
id autonumber primary key
userName text
read yes/no
write yes/no
delete yes/no
formName text

Wrap the ExecuteScalar in a try catch and see if you get any more info but I
think the problem is that username is a reserved word. Just for a test,
change it to _username and see if it works. This is the most likely culprit
b/c the connection is opening and you arne't getting permission exceptions.
In Access, if you use Date as a FieldName, it'll blow up on you, and I'm
guessing that username is the problem, it's defenitely a SQL Server reserved
word although SQLClient it pretty cool about it.

Let me know.

if i change the commandtext to just this
Dim cmdGetPermissions As New OleDb.OleDbCommand("SELECT read from
userformaccess")



it still crashes with the same exact error, and try catch gave me the same
information really... im really confused on this because im useing a similar
statement in a diffrent place and it works fine... what exactly does that
error mean?!

i figured it out with your help, read was a reserved word which was causeing
the crash, didn't even think about reserved words...
