SchemaIterator

sub new

Create a new SchemaIterator object with either a dbh or a file_itr.

Parameters

Required Arguments

Optional Arguments

Returns

SchemaIterator object

sub _make_filters

Create schema object filters from OptionParser options.  The OptionParser object passed to new() is checked for filter options like --database, --tables, --ignore-tables, etc.  For all such options, a hash is built keyed off the same option name.  So $filter{tables} represents --tables, etc.  Regex filters are pre-compiled.  It is very important to avoid auto-vivifying certain key-values; see below.  The filter hash is used in sub like database_is_allowed().

This sub is called from new().  That’s the only place and time it needs to be called because options shouldn’t change between runs.

Parameters

Required Arguments

Returns

Hashref of filters keyed on corresponding option names.

sub next_schema_object

Return the next schema object or undef when no more schema objects.  Only filtered schema objects are returned.  If iterating dump files (i.e. the obj was created with a file_itr arg), then the returned schema object will always have a ddl (see below).  But if iterating a dbh, then you must create the obj with a MySQLDump obj to get a ddl.  If this object was created with a TableParser, then the ddl, if present, is parsed, too.

Returns

Hashref of schema object with at least a db and tbl keys, like

{
   db         => 'test',
   tbl        => 'a',
   ddl        => 'CREATE TABLE `a` ( ...',  # if keep_ddl
   tbl_struct => <TableParser::parse()> hashref of parsed ddl,
}

The ddl is suitable for TableParser::parse().
