LOCK TABLE

LOCK TABLE table_list IN lock_mode MODE [NOWAIT];

Bypasses the implicit database row-level locks by explicitly locking one or more entire tables in the specified mode.

Keywords

table_list

Comma-delimited list of tables.

lock_mode

Can be ROW SHARE, ROW EXCLUSIVE, SHARE UPDATE, SHARE, SHARE ROW EXCLUSIVE, or EXCLUSIVE.

NOWAIT

Specifies that the RDBMS should not wait for a lock to be released. If there is a lock when NOWAIT is specified, the RDBMS raises the exception:

ORA-00054: resource busy and acquire with NOWAIT specified

The default RDBMS locking behavior is to wait indefinitely.
