Are there permissions required to delete table_names in user_tables

Question

i have  written  a stored procedure in it there is a line
"Delete from User_tables where TABLE_NAME like v_TableName;" this query deletes contents in TABLE_NAME column of USER_TABLES in DATABASE
but when i executed it it is showing ERROR  ": ORA-01031: insufficient privileges" i have seen session privileges but it is having CREATE PROCEDURE,CREATE ANY PROCEDURE,DELETE ANY TABLE
priveleges what could be the problem

Answer 1

user_tables is a view on the datadictionary. The datadictionary is maintained by DDL commands, like CREATE TABLE, DROP TABLE, etc.
In other words: you are on the wrong track.
You can not delete from any datadictionary view.
You need to use
EXECUTE IMMEDIATE 'DROP TABLE '||table_name;
And dropping tables through PL/SQL is also a very bad idea.
