Description:

Hi, is it possible to LOCK only PARTITION on partitioning table instead of
whole TABLE?
When I performed command LOCK with table partition name, no error raised,
but whole table was locked. Is it OK? We need to lock onli partition, not
whole table. This is the critical point in our migration from Oracle.

Thanks for reply.

Vladimir.
