Re: lock modes

Partial answer only:

See below for a code example (something I use to irritate users if run during normal data enty times!).

It shows how how to lock a table for "mass update" while running in SQL*plus (amazing enough, it was probably originally found in an Oracle manual).

Regards,
Eric

---begin---

    whenever sqlerror exit sql.code ;
    lock table STUDENT_MASTER in exclusive mode nowait ;     whenever sqlerror continue ;

---end---
