Re: BCE/CE Dates
... I have a, possibly not so unusual problem, with dates. The standard MySQL datatime accounts for all dates starting between the year and inclusive. ... Take a look at using Julian Day numbers. This date form is used in astronomy and general calendar conversions. Every day has an integer number and it handles pretty much any date you can imagine (as in the lifetime of the universe). Just convert your dates to JDNs for storage and convert back for display. Lots of code out there to do this.

Re: Outer join question
First, you database design. You don't need to separate actresses from actors... Why do that? They are the same entity, a person, with only one different attribute: the genre. So, you should join them in one single table: ... Actually, it is possible to be female and to be an Actor. For example, the Screen Actors' Guild officially considers the term Actor to be gender-neutral and applies this term to all people. ...

Re: Storing mysql dates as an integer
An unsigned int is probably more appropriate for timestamps than a signed int. Also note that the range for timestamps is 1970 until 2038 (or 2106? for unsigned ints), where DATE and DATETIME have a much greater range. Using a UNIX timestamp for birthdays might not be appropriate. Many Unix systems are transitioning to a 64-bit timestamp: that should cover most needs...(:-). In the meantime, while there may be a some applications where it is important to keep both the date AND time for a range outside of 1970-2038, I can't think of one outside of astronomy. Most applications that need dates outside of that range don't need much in the way of times in general and timezone adjustments in particular. When I am storing event timestamps, I use Unix 32-bit timestamps (which are in GMT) as the base and either convert to local time for printing or store a printed version (in -mm-ddThh:mm:ss- form) in anotehr column where appropriate. Storing the latter makes date-based selection easy. Craig -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
installation question...missing 'host.frm'
I am trying to install: mysql-standard-4.0.14-sun-solaris2.8-sparc.tar on a Solaris 8 system. I am getting this message in the .err file: 030910 11:05:41 mysqld started 030910 11:05:41 InnoDB: Started 030910 11:05:41 Fatal error: Can't open privilege tables: Can't find file: './mysql/host.frm' (errno: 13) 030910 11:05:41 Aborting I haven't been able to find any reference to that file in any of the MySQL documentation. I've tried creating such a file, but the message remains unchanged. I am doing a little weird install. The commands and scripts go into /usr/local/bin and the database lives in /local/mysql. I have added symbolic cross links. Anyone have any ideas? Craig A.

Re: installation question...missing 'host.frm'
Errno 13 indicates that you have some permission issues. Check the data directories you've set up to make sure that they are owned by the user/group mysql. Thank you. That was the problem. The host.frm really threw me. Craig -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
