Otherwise, an exception will be thrown. The result rows will have > the values of the column if the rows are from the component tables that have > the column themselves, or null if otherwise. > The order preserving sort-unioned results could be further indexed by the > component tables if the projection contains column(s) named "source_table". > If so specified, the component table index will be output at the position(s) > as specified in the projection list. If the underlying table is not a union > of sorted tables, use of the special column name in projection will cause an > exception thrown. > If an attempt is made to create a table of a column named "source_table", an > excpetion will be thrown as the name is reserved by zebra for the virtual > name. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
