Oracle Error Message
ORA-29252: collection does not contain elements at index locations in call to dbms_sql.bind_array
Reason for the Error
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.
Solution
Either modify the two indexes or the contents of the table and try the call again.
