Some Miscellaneous dbish Commands
As dbish is a fairly fully featured command-line
shell,[66] it has some convenient commands defined within it that
allow you to commit and roll back database changes, recall statements
and commands that you’d executed in the past, and even execute
arbitrary Perl statements!
One of the most useful of the miscellaneous statements is
/table_info
, which lists the tables in the database
that you are currently connected to. This statement is indispensable
when you’re trying to remember exactly what that pesky table
name is!
A full list of these commands can be seen by typing the all-important
/help command.
dbish is currently a handy tool for performing
quick tasks on a database. It should continue to evolve over time
into an indispensable part of the database administrator’s and
database developer’s armory, much like proprietary tools such
as Oracle’s SQL*Plus utility.
[66]
dbish’s powerful
command-line editing functionality comes courtesy of the
Term::Readline
and
Term::Readline::Gnu
modules. You don’t need to install
them to use dbish, but it helps.
