mysql表锁定 phpmyadmin,如何锁定MySQL或phpmyadmin中的表？

I need to use a table for a queuing system. The table will be constantly be updated.

For example, multiple users on my website, will add their files for process, and I heard that when updates occur simultaneously from multiple users, the table becomes non responsive or something like that.

so do I need locking tables in this situation ? how do i apply a lock to a mysql table ?

When you do several updates at once, you can get into a deadlock situation. Engines such as InnoDB will detect this and fail one of your transactions (You can retry, but only the whole transaction).

You can avoid this by table locking, but it reduces concurrency.

Engines such as MyISAM (which does not support MVCC or transactions anyway) use table locking implicitly anyway. Such table locks exist only for the duration of a query; they're automatically released soonish after the table isn't needed any more (not necessarily as soon as possible, but quite soon)

I recommend you do not use LOCK TABLE unless you feel you really need to; if you get a deadlock, retry the transaction.
