Make CsvEnumerator a top-level class.
Optiq adapter that reads CSV files.
Optiq-csv is a nice simple example of how to connect Optiq to your own data source and quickly get a full SQL/JDBC interface.
You need Java (1.5 or higher; 1.7 preferred) and maven (2 or higher).
$ git clone git://github.com/julianhyde/optiq-csv.git $ cd optiq-csv $ mvn compile
$ ./sqlline sqlline> !connect jdbc:optiq:model=target/test-classes/model.json admin admin sqlline> select * from emp; sqlline> !tables sqlline> !quit
You can also register a CsvSchema as a schema within an Optiq instance. Then you can combine with other data sources.
You can write a “vanity JDBC driver” with a different name.
You can add optimizer rules and new implementations of relational operators to execute queries more efficiently.
