OUTPUT parameters — An instance of
java.sql.ResultSetHolder, which contains a class that implements the
com.progress.open4gl.ProResultSet interface, which extends the
java.sql.ResultSet interface.
INPUT-OUTPUT parameters — An instance of the
com.progress.open4gl.ResultSetHolder class that contains a reference to a client-supported
java.sql.ResultSet object instance. On output, the
ResultSetHolder contains an instance of
com.progress.open4gl.ProResultSet.
OpenEdge provides the abstract class,
com.progress.open4gl.InputResultSet, which provides part of an implementation of
java.sql.ResultSet. You can extend this class to implement your own input
ResultSet objects. For more information, see
Passing a TABLE or TABLE-HANDLE as an INPUT parameter.
The
java.sql.ResultSet interface allows you to get the values of columns in the underlying temp-table. The extensions in the
ProResultSet interface allow you to get the values of ABL fields, especially array fields, in a more ABL-like manner. For more information on how to access column and field values using the
ProResultSet interface, see
Accessing TABLE or TABLE-HANDLE parameters as OUTPUT.
