David,
The easiest way to do this is to construct a command string and run that. eg
Dim exp as String
dim cmd as string
exp = "A, B, C"
cmd = "Select "+exp+ "from test"
run command cmd
Hope this helps

Subject: MI Multiple columns selection in SQL
Hi dear friends,
I want to select more than one columns in one SQL statement. How can I use a
string or alias variable as the expression after the Select key word? Like I
have a table named Test with four columns A, B, C, and D. Can I do this:
Dim exp as String (or Alias)
exp = "A, B, C"
Select exp From Test
I tried, but it didn't work. Thanks in advance for any help,
David Hou
