Um, no. Select for update will lock whatever rows it selects. If it happens to select all the rows in a table, then all the rows in the table will be locked. But, you could select for update where primary_key=1 and select (and lock) just one row. As with other DML locks, the lock will be released when you commit or rollback.
See the concepts manual for more details. Hope that helps, -Mark On Fri, 2002-09-27 at 20:33, tony ynot wrote: > Is Select ...
