minor - for readability, can we extract some of these out into descriptive variables?

Number of parameters and parameter type have been extracted to variables and the if-statement has been partially re-written as a switch statement.

ResultSetimplementation defers the execution of a query to the first call toResultSet#next(). The JDBC Driver requires that queries are executed directly when a statement is passed to the driver, and that any query errors are returned directly. TheDirectExecuteResultSetis a wrapper around a normal result set that ensures that the query is executed directly, and that any query errors are propagated directly when the result set is created, instead of deferring this until the first call toResultSet#next().
