Quartz Composer Plugin

SQLiteQuery                 A Quartz Composer plug-in that performs a query on a 

                        local SQLite database.

Sample Requirements             The plugin was created using the Xcode editor running 

                        under Mac OS X 10.6.x or later. 

About the sample                A Quartz Composer plug-in that queries synchronously a 

                        SQLite 3 database on disk and outputs the results as a 

                        structure. SQLite is a self-contained, serverless,

                        zero-configuration, and transactional SQL database

                        engine. SQLite reads and writes a complete SQL database

                        to a single disk file. It is a popular database engine

                        choice on memory constrained gadgets. This plug-in 

                        retrieves information from a SQLite database.

                        Given a SQLite database and a SQL query, the result 

                        will be returned. The default database path is set to 

                        Database.db which can be found in this sample.

Using the Sample                Open the project using the Xcode editor which can be found 

                        in /Developer/Applications. From the main menu, 

                        choose "Project", set "Active Configuration" to "Release", 

                        and "Active Target" to "Build & Copy".  These settings are

                        also available from the top left corner of the 'Overview' 

                        pull-down window. Build the project. Once the build has 

                        completed successfully, the plug-in can be used as a 

                        regular QC patch in the Quartz Composer editor (also 

                        installed under /Developer/Applications), by selecting it 

                        from the Library - Plugin panel.

                        This plug-in requires the query and the database path in 

                        the input ports. The results are returned in the output 

                        port "Result Structure".
