NAME

       SQL::Translator::Parser::xSV - parser for arbitrarily delimited text files

SYNOPSIS

	 use SQL::Translator;
	 use SQL::Translator::Parser::xSV;

	 my $translator  =  SQL::Translator->new(
	     parser	 => 'xSV',
	     parser_args => { field_separator => "	" },
	 );

DESCRIPTION

       Parses arbitrarily delimited text files.  See the Text::RecordParser manpage for arguments on how to parse the file (e.g.,
       "field_separator", "record_separator").	Other arguments include:

OPTIONS

       o   scan_fields

	   Indicates that the columns should be scanned to determine data types and field sizes.  True by default.

       o   trim_fields

	   A shortcut to sending filters to Text::RecordParser, will create callbacks that trim leading and trailing spaces from fields and
	   headers.  True by default.

       Field names will automatically be normalized by "SQL::Translator::Utils::normalize_name".

NAME

       SQL::Translator::Parser::DBI - "parser" for DBI handles

SYNOPSIS

	 use DBI;
	 use SQL::Translator;

	 my $dbh = DBI->connect('dsn', 'user', 'pass',
	     {
		 RaiseError	  => 1,
		 FetchHashKeyName => 'NAME_lc',
	     }
	 );

	 my $translator  =  SQL::Translator->new(
	     parser	 => 'DBI',
	     dbh	 => $dbh,
	 );

       Or:

	 use SQL::Translator;

	 my $translator      =	SQL::Translator->new(
	     parser	     => 'DBI',
	     parser_args     => {
		 dsn	     => 'dbi:mysql:FOO',
		 db_user     => 'guest',
		 db_password => 'password',
	   }
	 );

DESCRIPTION

       This parser accepts an open database handle (or the arguments to create one) and queries the database directly for the information.

       The following are acceptable arguments:

       o   dbh

	   An open DBI database handle.  NB:  Be sure to create the database with the "FetchHashKeyName => 'NAME_lc'" option as all the DBI
	   parsers expect lowercased column names.

       o   dsn

	   The DSN to use for connecting to a database.

       o   db_user

	   The user name to use for connecting to a database.

       o   db_password

	   The password to use for connecting to a database.

       There is no need to specify which type of database you are querying as this is determined automatically by inspecting
       $dbh->{'Driver'}{'Name'}.  If a parser exists for your database, it will be used automatically; if not, the code will fail automatically
       (and you can write the parser and contribute it to the project!).

       Currently parsers exist for the following databases:

       o   MySQL

       o   SQLite

       o   Sybase

       o   PostgreSQL (still experimental)

       Most of these parsers are able to query the database directly for the structure rather than parsing a text file.  For large schemas, this
       is probably orders of magnitude faster than traditional parsing (which uses Parse::RecDescent, an amazing module but really quite slow).

       Though no Oracle parser currently exists, it would be fairly easy to query an Oracle database directly by using DDL::Oracle to generate a
       DDL for the schema and then using the normal Oracle parser on this.  Perhaps future versions of SQL::Translator will include the ability to
       query Oracle directly and skip the parsing of a text file, too.
