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

drop_database

DROP 
DATABASE(7)						   SQL Commands 						  DROP DATABASE(7)

NAME

       DROP DATABASE - remove a database

SYNOPSIS

       DROP DATABASE [ IF EXISTS ] name

DESCRIPTION

       DROP  DATABASE drops a database. It removes the catalog entries for the database and deletes the directory containing the data. It can only
       be executed by the database owner.  Also, it cannot be executed while you or anyone else are connected to the target database. (Connect	to
       postgres or any other database to issue this command.)

       DROP DATABASE cannot be undone. Use it with care!

PARAMETERS

       IF EXISTS
	      Do not throw an error if the database does not exist. A notice is issued in this case.

       name   The name of the database to remove.

NOTES

       DROP DATABASE cannot be executed inside a transaction block.

       This  command  cannot  be  executed  while  connected  to  the target database. Thus, it might be more convenient to use the program dropdb
       [dropdb(1)] instead, which is a wrapper around this command.

COMPATIBILITY

       There is no DROP DATABASE statement in the SQL standard.
