OpenLink Virtuoso 5.0.9 (Open-Source branch)
OpenLink Virtuoso is a scalable, high-performance SQL-200n compliant object-relational database engine. It provide sophisticated database management for SQL, XML, and RDF. All interaction with Virtuoso occurs via its support of industry standard query languages, protocols, APIs, and data formats such as: ODBC, JDBC, OLE-DB, ADO.NET, XMLA, SQL, SPARQL, XQuery, SOAP, HTTP, WebDAV, SyncML, Atom (Publishing and Syndication), RSS, RDF, and more. License: GNU General Public License (GPL) Changes:
This version brings performance optimizations for the SQL and SPARQL engines and ODBC and JDBC drivers. New features include: an Excel MIME-type output option in the SPARQL endpoint; triple options bif:contains and transitivity; new RDF-generating cartridges with UMBEL lookups for the Sponger; support for very large HTTP client requests; a sparql-auth endpoint with digest authentication; and support for the Ubiquity Firefox plugin. There are also minor bugfixes for memory leaks, SPARQL "select distinct", and various SQL query syntax handling. XHTML validation is done in the ODS application suite. Image

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.
