row locking for most applications, but there are, of course, some
pitfalls.
For @code{BDB} tables, @strong{MySQL} only uses table locking if you
explicitely lock the table with @code{LOCK TABLES} or execute a command that
will modify every row in the table, like @code{ALTER TABLE}.
For @code{BDB} and @code{InnoDB} tables, @strong{MySQL} only uses table
locking if you explicitely lock the table with @code{LOCK TABLES} or
execute a command that will modify every row in the table, like
