You should use the `FLUSH' command if you want to clear some of the internal caches *MySQL* uses. To execute `FLUSH', you must have the *reload* privilege.
FLUSH TABLES closes all open tables. If you want table level locks, use LOCK command. LOCK TABLES tbl_name [AS alias] {READ | [READ LOCAL] | [LOW_PRIORITY] WRITE} [, tbl_name {READ | [LOW_PRIORITY] WRITE} ...] ... UNLOCK TABLES LOCK TABLES works as follows: Sort all tables to be locked in a internally defined order (from the user standpoint the order is undefined). If a table is locked with a read and a write lock, put the write lock before the read lock. Lock one table at a time until the thread gets all locks. For READ ONLY, use LOCK TABLES <table name> WRITE Barnali Persistent Systems Pune, India -----Original Message----- From: Charitha [mailto:[EMAIL PROTECTED]] Sent: Monday, July 22, 2002 1:50 PM To: Barnali Cc: [EMAIL PROTECTED] Subject: usage of mysql command Actually i want to lock a db in mysql with the flush command should i go thru CPAN for that purpose or i can do it with a single command like mysql -uxxxx -pxxxx DBNAME --execute "flush tables with read only" i have tried this but it is not working for me that is why i put that mail Is there anyone to correct this??????? thank you.
