next.jdbc.result-set
An implementation of ResultSet handling functions.
Defines the following protocols:
DatafiableRow-- for turning a row into something datafiableReadableColumn-- to read column values by label or indexRowBuilder-- for materializing a rowResultSetBuilder-- for materializing a result set
Also provides the default implemenations for Executable and
the default datafy/nav behavior for rows from a result set.
An implementation of `ResultSet` handling functions. Defines the following protocols: * `DatafiableRow` -- for turning a row into something datafiable * `ReadableColumn` -- to read column values by label or index * `RowBuilder` -- for materializing a row * `ResultSetBuilder` -- for materializing a result set Also provides the default implemenations for `Executable` and the default `datafy`/`nav` behavior for rows from a result set.

ReadableColumncljprotocol
Protocol for reading objects from the java.sql.ResultSet. Default
implementations (for Object and nil) return the argument, and the
Boolean implementation ensures a canonicalized true/false value,
but it can be extended to provide custom behavior for special types.
