Oracle DB: Get All the Foriegn Keys References on a Specific Column

At times it is useful to know all the foreign keys of a specific table column. The query provided here will give you the table name that has the foreign key, the name of the foreign key constraint, the table and column the foreign key reference to. Change the value for ucc.column_name to the column name you want all the foreign key references of.

SELECT
   uc.table_name as foreign_table,
   uc.constraint_name as foreign_constaint_name,
   ucc.table_name,
   uc.r_constraint_name,
   ucc.column_name
FROM
   user_constraints uc,
   user_cons_columns ucc
WHERE
   uc.r_constraint_name = ucc.constraint_name AND
   uc.constraint_type = 'R' AND
   ucc.column_name = 'USR_KEY';

How Give a User sudo Power?

This post demonstrates how to add a user to the sudoers list on a Linux Operating System.

1. Open a terminal and login as the root user.

su root

2.Open  the "/etc/sudoers" file or execute "visudo".

vi /etc/sudoers
visudo #The same as the command above

3. Add a new line below the root user.
Format: <username> ALL=(ALL)       ALL

## Next comes the main part: which users can run what software on
## which machines (the sudoers file can be shared between multiple
## systems).
## Syntax:
##
##      user    MACHINE=COMMANDS
##
## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
oracle ALL=(ALL) ALL

4. Save the file. Now your user should have root privileges.

sudo [command]
