title: ORA-00001: unique constraint check data source
body: <p>I got an ORA-00001: unique constraint error when I executed a procedure.
  I checked the table name and it has four primary keys. (a.sr_date, a.int_key, b.cli_no, b.act_no) from table1 a, table2 b
  I would like to know how I'm going to check the source tables so I would know what are the data that is causing the problem.
  Appreciate any help.
  Thank you.</p>
