Re: How to Find Every View In Which a Column is Used.

I can find out the name of the views which access the table via "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.
