Re: Need assistance with a 'VIEW'.

A view is simply an SQL statement. In your case you want the user to be able to specify a specific date. The problem is quite specific: Each different date makes a new SQL statement. But a view is based on a single SQL statement, not multiple SQL statements.

It's like saying you want to sew a jacket, but you want to sew it in such a way that people of different sizes will be able to change the size when they put it on so it will fit them perfectly. There is no way to sew a single jacket that will do that.

Why not make a simple SQL*Plus script that uses ACCEPT to get a variable from a user. Then the SQL will be modified each time to include the date the user specifies.

Apparently the reason for wanting to create a view is you want users to then be able to select against it. That can be accomplished by using ACCEPT to get values from the users for those columns, too.
