Hi, thanks for your replies,
if I use:
select companyID from
or
select * from
it will work.
My dataset is a new empty dataset.
but if I use
select [company name] from
I will get the error information, it seems the command doesn't support []
Any idea?
Because I don't want to select all of columns and use the index, it is a
huge table.
Thanks a lot.
