Home -> Community -> Mailing Lists -> Oracle-L -> RE: How to Find Every View In Which a Column is Used.
Ugly way:
1- Select the list of valid views. 2- Rename the table. 3- Create new table with the same name but missing the column (empty table). 4- Compile all views. 5- Invalid views are using this column.

"dependencies", get the view text and parse it by eye. But I don't want
to do that. I want the database to do so. I can use dbms_dql.parse,
dbms_sql.describe columns, and the text of the view; however, this method
does not work very well if the view contains a function or an operation on
the column.

Ian,
To the best of my knowledge, the 'per column' dependency is not
stored in the dictionary. The finest grain is the dependence of the view
on the table. And as you pointed out, the description gives you the
column name, which is arbitrary.
No way out but parsing a LONG column :-P.
