The Stream operator uses macros to modify tables rather than actual DML statements. Before beginning a load, the operator creates macros to represent the DML statements. The macros are then iteratively executed in place of the DML statements. The Stream operator also removes the macros after all rows are loaded.

These actions are accomplished through the use of CREATE/DROP MACRO SQL statements.

Use the MacroDatabase attribute to specify the database that contains the macros created by the Stream operator. If not specified, the database used is the database that contains the Restart Log table.
