LOCK TABLES permission and 4.0.15a
Hello, My ISP is using the old version 4.0.15a and have no early plans to upgrade it. I'm trying to issue LOCK/UNLOCK TABLES commands at my ISP's MySQL, and I'm getting an access denied error. I asked them to give me the lock tables permission, but they answered this permission option isn't available on versions prior to 4.0.2. They also told me they would have to give me a high elevated previledge to issue these commands. Is it true ? A plain user with full database (but no grant all) access cannot lock a table ? Could someone please point me a solution ??

Re: LOCK TABLES permission and 4.0.15a
Version 4.0.15 comes after version 4.0.2 (15 2), so the version is not a problem here. From the manual: As of MySQL 4.0.2, to use LOCK TABLES you must have the global LOCK TABLES privilege and a SELECT privilege for the involved tables. http://dev.mysql.com/doc/mysql/en/LOCK_TABLES.html The LOCK TABLES privilege may seem elevated as it is global, but you can only lock tables for which you have the SELECT privilege.

Thank you for you explanation about the lock table permission !! Regards, Fernando Monteiro You're welcome. If you look at the quote I included from the manual, the LOCK TABLES privilege has been available since version 4.0.2, so they are wrong if they told you 4.0.20. The next sentence in the manual after the one I quoted is In MySQL 3.23, you must have SELECT, INSERT, DELETE, and UPDATE privileges for the tables. In other words, the LOCK TABLES global privilege was added in 4.0.2 to further restrict who could lock tables. So, again, the version of mysql is not a problem -- the ability to lock tables has been in mysql for a long time. In fact, prior to 4.0.2 you would most likely have been able to lock tables already, as I imagine you do have SELECT, INSERT, DELETE, and UPDATE privileges on your own tables. They can give you the ability to lock tables in 4.0.15, if they choose to. If they are your tables, I'm not sure why they are reluctant to do so. The only reason I can think of would be if they have already given you SELECT permission on tables which are not yours, which they don't want you to lock. Now that you are armed with the truth, perhaps you can get them to tell you their real reasons...
