I have a table as follows

book_num book_name book_price book_version
1 A 10 1
2 B 20 1
3 C 30 2
4 D 100 4
2 B 20 0

Now i want to create a view with following conditions

1)Reflect all columns in the above table( what ever columns that may be added in future )
2)I should not alter the procedure when a new column is added to the above table in future
3)I want to retrieve all the book_versions = 0 and 1
4)we may get two rows same (when we put the conditon 0 and 1)
ex: book_num 2

in such cases i want to remove book_version 1 coz all other columns are repeating

Please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code (See SQL Formatter), use code tags and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version (4 decimals).

Use SQL*Plus and copy and paste what you already tried.
