Obtain information from the database by using the program
query-pr. query-pr uses search parameters you provide
to find matching Problem Reports in the database. You can invoke
query-pr from the shell or from within Emacs. query-pr
uses the same arguments whether it is invoked from the shell or from
Emacs.
PRs may be selected via the use of the --expr option, directly by
number, or by the use of the (now deprecated) field-specific query
operators.
By default, query options are connected with a logical AND. For example,
query-pr --category=foo --responsible=bar
only prints PRs which have a Category field of foo and a Responsible field of bar.
The --or option may be used to connect query options with a logical
OR. For example,
query-pr --category=baz --or --responsible=blee
prints PRs which have either a Category field of baz or a Responsible field of blee.
It should be emphasized, however, that the use of these field-specific
options is strongly discouraged, since they exist only for compatibility
with older versions of gnats and are likely to be deleted in the next
release. The expressions specified by the --expr option are much more
flexible (see below).
