bin/db-browser view on Meta::CPAN
Before using C<db-browser>, ensure you have backed up your databases.
Search and read in SQL databases: one can interactively browse databases and their tables.
C<App::DBBrowser> provides and supports plugins for the DBI drivers C<DBD::SQLite>, C<DBD::mysql>, C<DBD::MariaDB>,
C<DBD::Pg>, C<DBD::Firebird>, C<DBD::DB2>, C<DBD::Informix>, C<DBD::Oracle> and C<DBD::ODBC>. Refer to
L<App::DBBrowser::DB> for guidance on writing a database plugin.
=head1 NAVIGATION

bin/db-browser view on Meta::CPAN
Control characters, code points of the surrogate ranges and non-characters are removed.
See also the option group L</Output>.
C<Ctrl-F> opens a prompt. A regular expression is expected as input. This enables one to display only rows where at
least one column matches the entered pattern. See option L</Search>.
=head1 MENUS
=head2 Plugins Menu
Choosing a plugin leads to the I<Databases Menu>.
(If there is only one plugin, the plugins menu is not shown, but the plugin is chosen automatically.)
=head2 Databases Menu
Choosing a database leads to the I<Schemas Menu>.
(If there is only one database, the databases menu is not shown, but the database is chosen automatically.)
=head2 Schemas Menu

(If there is not more than one schema, the schemas menu is not shown, but the schema is chosen automatically.)
=head2 Tables Menu
The menu entries of the tables menu:
=head3 Prompt Line
Selecting the prompt line (the database name) opens a menu with these entries:
=over
=item
bin/db-browser view on Meta::CPAN
For I<Create Table>, I<Drop Table>, I<Create View> and I<Drop View>, see L</WRITE ACCESS>.
These entries are available if enabled in L</Extensions>.
I<Attach DB> is available for C<SQLite> databases. I<Attach DB> can be used to attach databases to the current database.
For DB Settings, see L</DB Settings>.
=head3 Tables Entries
Choosing one of the tables leads to the I<SQL Menu>.
=head3 Subquery
I<Subquery> is available if enabled in L</Extensions>.
Enter a subquery and use it as a table.
The query can be created in different ways:

of the data source. If I<Source Type> is set to I<plain> or I<file>, the set data source type is automatically used
without displaying a menu. For more information, see L</Data Input>.
bin/db-browser view on Meta::CPAN
=head3 Create View
Before creating a view, print the required select statement to make it available in the subquery menu.
=head3 Drop View
Drop a view. The entire view is shown before the user confirms dropping it.
=head2 Insert/Update/Delete
I<Insert>, I<Update> and I<Delete> can be accessed by selecting the prompt-line in the L</SQL Menu> if the respective

In the prompt line menu of the L</Tables Menu>, the entry I<DB Settings> (if enabled in L</Extensions>) allows users to
make database-specific settings. If no database-specific settings are set, these global settings (for the database
plugin) I<DB Settings> are used.
User-defined database plugins: The options offered to be set in each option and whether the user's selections are
considered depend on the plugin.
