ORA-02270: no matching unique or primary key for this
column-list

Answer Posted / chetan

CAUSE:You tried to reference a table using a unique or
primary key, but the columns that you listed did not match
the primary key, or a primary key does not exist for this
table.
SOL:
This error commonly occurs when you try to create a foreign
key that references a table that doesn't have a primary
key. To resolve this problem, create a primary key on the
referenced table. Then re-execute your command to create
the foreign key.
