DynamicDescriptionArea object
DynamicDescriptionArea is a PowerBuilder system object
that stores information about the input and output parameters used
in Format 4 of dynamic SQL.
PowerBuilder provides a global DynamicDescriptionArea named SQLDA that you can use when you
need a DynamicDescriptionArea variable. If necessary, you can declare
and create additional variables of this type using this system object
as the datatype.
For more information about using dynamic SQL, see the PowerScript Reference.
