Several answers:

Try looking at the documentation, its pretty well documented there.
To add a simple column key for a view, you can show the rownum, but for the life of me I cant think why you would want to, since it wont be stored anywhere.
To show a combined column, use the concat function (||). Ok, some people on the list will think I am too kind, but try looking at (1), and read the doc.

Subject: questions about views

Hi all,
I am new to oracle and views and I have two questions: 1. How can I add a new integer columns, which can simply start with 1 and count, as a primary key to a view I. e. i have have the select query, which is fine, and I just want the new column as the first column in the table. 2. Can I put two queries in one view? I have a table, which has two columns, the values of these columns are supposed to go in one column. No problem to select one of them, but I have no idea how to do it with both columns. Thanks for help
Stefan
