Question

For regression testing i need to dump the entire contents of an SQLite database into a text file. But all references to that sort of activity only lead to guides using the sqlite executable. Is there a way in Perl to do this without the executable?

Answer 1

You can use the standard DBI methods for querying schema. DBD::SQLite manpage says:

See also to the DBI documentation for
the details of other common methods.

table_info

 $sth = $dbh->table_info(undef, $schema, $table, $type, \%attr);

Returns all tables and schemas
(databases) as specified in
“table_info” in DBI. The schema and
table arguments will do a “LIKE”
search. You can specify an ESCAPE
character by including an ’Escape’
attribute in \%attr. The $type
argument accepts a comma separated
list of the following types
’TABLE’, ’VIEW’, ’LOCAL TEMPORARY’ and
’SYSTEM TABLE’ (by default all are
returned). Note that a statement
handle is returned, and not a direct
list of tables.
