title: The ROWID values between schemas
body: <p>Rowid is a unique identifier of a row of a  table in database(oracle). I wanted to know if the rowid can repeat between tables in different schemas in the same database and different schemas in different databases ?</p>
  
  <p>For example - </p>
  
  <ol>
  <li>Database (D1) has Schemas (S1 and S2). Can a table S1.Customer have
  same rowid as S2.Customer ?</li>
  <li>Databases(D1 and D2) have Schemas (S1 and S2) respectively. Can a
      table D1.S1.Customer have same rowid as D2.S2.Customer ?</li>
  </ol>
