Re: Problem with mysqlimport and timestamp

You should alter your data like so: test\N test That is, separate the fields with a tab and place "\N" wherever you want a NULL. As it is, the data is being misinterpreted, which is why the second import you mentioned worked--there was nothing after the first field to be erroneously put into the timestamp field. If the data comes from somewhere else you will need to parse it out and re-write it using proper formatting, i'm afraid. brian -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

server optimization
Hey all, I've got a new server set up, with dual Intel quad core processors, 4 gig of ram, OpenSuse 10.3 (64bit) and MySql 5.0.45. The majority of the tables are MyISAM with a few InnoDB here or there. I'm using the huge-my.cnf as the base for my config. Can anyone suggest some tweeking to the my.conf that will give me the best performance on this platform?

Thank you, Sebastian. Also does the usage of UTF-8 over Latin1 restraints the usage or extensibility?

How to grant privileges using REVOKE statement
Hi All! Here is a funny thing I come across when investigating our privilege control system. Consider the following situation: mysql> GRANT ALL ON `%o`.* TO rafal; mysql> GRANT SELECT ON foo.* TO rafal; The intention is that rafal has all privileges for all objects in databases whose name ends with 'o' but he has read-only access to the tables in the 'foo' database. Now imagine DBA decides that rafal should no longer be able to see the data inside the foo database. Then he might issue command mysql> REVOKE ALL ON foo.* FROM rafal; and... tada! rafal has all rights to all tables inside database 'foo'. The reason is that REVOKE command, when it sees that all rights have been revoked, removes the corresponding entry in the privilege table inside mysql database (mysql.db in that case). But removing such entry doesn't mean that all rights will be taken away, since, as this example illustrates, some other entry can apply after removing that one and in fact give more rights than before! A solution would be to not remove any entries when REVOKE is executed - just clear the corresponding flags in the existing entry.

Re: MySQL 5.1.22 is out
Hi Jim, all ! Jim wrote: Is there any kind of timetable for when 5.1 is actually expected to be released? Sorry, no - there cannot be any firm "expectation" yet, and consequently no "timetable". Different people have different *hopes* when that may be, but these personal estimates will be made concrete only by facts and experiences. Consider the following parts of Kaj's blog / mail you quoted: [[...]] We still have some fatal runtime bugs left. We are producing an errata list of these, and expect to have the list ready and published on by 23 Oct 2007. [[...]] Only when this list is available and all its elements have been judged, we will have a full (but only momentary) overview of what still needs to be done. That said, 5.1.22 is a great release, one that we're proud of, and very likely worthy of your attention! So for the MySQL development to bring 5.1 to a true "GA" status, we really need and appreciate your help and feedback, be it bug reports (we sure hope only few ones, but who knows ?) or (positive ?) messages like "I used feature X with the Y amount of data and Z of users/transactions and had these experiences: ...". Regardless of how much we improve and strengthen our own QA, it will never be able to fully mimic the ideas/workload/diversity of our users. Any such feedback, be it negative or (hopefully !) positive, will make that overview more exact and complete.
