Passing a TEMP-TABLE Or TABLE-HANDLE As an OUTPUT Parameter
For an OUTPUT parameter, you must pass an instance of
com.progress.open4gl.ResultSetHolder
which is theHolder
class for aProResultSet
object. The contents of this object are left empty by the client. On return, the holder’s contents is set to acom.progress.open4gl.ProResultSet
object. When the method returns, the Java client calls back through this object’s methods to get the data. For more information oncom.progress.open4gl.ProResultSet
, see the "Accessing TEMP-TABLE Or TABLE-HANDLE Parameters As Output" section.If the parameter is a TABLE-HANDLE, the value returned can be unknown or undefined. As a result, calling
getObject()
on the holder returns null.
