The http://stackoverflow.com/questions/23318805/ora-02291integrity-constraint-system-sys-c007150-violated-parent-key-not-fo table contains the following: Name Null?

To find out parent_table do as SELECT uc.constraint_name || CHR (10) || '(' || ucc1.TABLE_NAME || '.' || ucc1.column_name || ')' constraint_source, 'REFERENCES' || CHR (10) || '(' || ucc2.TABLE_NAME || '.' || ucc2.colu
