Database Reference
In-Depth Information
The most commonly used section of the
Search
interface (the query by example) is
the one immediately displayed, whereas other dialogs are hidden in a slider that can
be activated by the
Options
link (more on these dialogs later in this chapter).
Search criteria by field—query by example
The main use of the
Search
panel is to enter criteria for some fields so as to retrieve
only the data we are interested in. This is called
query by example
because we give
an example of what we are looking for. Our first retrieval will concern finding the
book with ISBN
1-234567-89-0
. We simply enter this value in the
isbn
box and choose
the
Operator
'
=
'.
Clicking on
Go
gives these results (shown partially in the following screenshot).
