ORA-29252: collection does not contain elements at index locations in call to dbms_sql.bind_array
Cause: The bound table does not contain elements at both index locations in call to bind_array of dbms_sql. This is illegal. Both index locations must contain elements. In other words tab.exists(index1) and tab.exists(index2) must both return true.
Action: Either modify the two indexes or the contents of the table and try the call again.
