I HAVE 2 TABLES one called
developers and skills
here the fields
f_name skills_sets
l_name skill_id
name_id
using this command to link the tables
ALTER TABLE developers ADD (CONSTRAINT qs_sessions
FOREIGN KEY (name_id)
REFERENCES skills (name_id))
I recieved the following error
The following error has occurred:
ORA-02270: no matching unique or primary key for this column-list
what am I doing wrong is my design wrong.

The reference, in your case skills.name_id, has to be the primary key or have a unique constraint.
(Are you sure you want to refere from the developer table to the skills and not from the skill to the developper table?)
