| Dear all,
I have a view. When I select data, I have to use double quotation on selected column name, for instance:
select "assy_no" from myView;
if I try
select assy_no from myView
I will get error: ORA-00904: "ASSY_NO": invalid identifier
When I query on table, double quotation is not required.
Why the column name on view requires double quotation?
