Erase the current
criterion in the City
column, and then
type [Enter City]
as the new criterion
(Figure 2–20).
What is the purpose of
the square brackets?
The square brackets
indicate that the text
entered is not text
that the value in the
column must match.
Without the brackets,
for example, Access
would search for
records on which the
city is Enter City.

What if I typed a
fi eld name in the
square brackets?
Access would simply
use the value in that
fi eld. In order to create
a parameter query, it is
essential that the text
typed in the square
brackets not be a
fi eld name.
