next.jdbc.protocols
This is the extensible core of the next generation java.jdbc library.
Sourceable protocol: get-datasource -- turn something into a javax.sql.DataSource; implementations are provided for strings, hash maps (db-spec structures), and also a DataSource (which just returns itself).
Connectable protocol: get-connection -- create a new JDBC connection that should be closed when you are finished with it; implementations are provided for DataSource and Object, on the assumption that an Object can possibly be turned into a DataSource.
Executable protocol: -execute -- given SQL and parameters, produce a 'reducible' that, when reduced, executes the SQL and produces a ResultSet that can be processed; implementations are provided for Connection, DataSource, PreparedStatement, and Object (on the assumption that an Object can be turned into a DataSource and therefore used to get a Connection).
-execute-one -- given SQL and parameters, executes the SQL and produces the first row of the ResultSet as a datafiable hash map (by default); implementations are provided for Connection, DataSource, PreparedStatement, and Object (on the assumption that an Object can be turned into a DataSource and therefore used to get a Connection).
-execute-all -- given SQL and parameters, executes the SQL and produces either a vector of datafiable hash maps from the ResultSet (default) or a vector of column names followed by vectors of row values; implementations are provided for Connection, DataSource, PreparedStatement, and Object (on the assumption that an Object can be turned into a DataSource and therefore used to get a Connection).
Preparable protocol: prepare -- given SQL and parameters, produce a PreparedStatement that can be executed (by -execute above); implementation is provided for Connection.
Transactable protocol: -transact -- given a function (presumably containing SQL operations), run the function inside a SQL transaction; implementations are provided for Connection, DataSource, and Object (on the assumption that an Object can be turned into a DataSource).
