SQL::Translator::Parser::DBI(3pm)			User Contributed Perl Documentation			 SQL::Translator::Parser::DBI(3pm)

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. AUTHOR
