Any help would be appreciated. Cron will allow you to put together shell scripts and work in other ways to achieve this. Will leave details to you/your system/your preferences. MySQL has a "batch mode". Once you know the terminology, a search of the manual will yield a ton of material. Check out: 3.6 Using mysql in Batch Mode for shell> mysql < batch-file (you will probably need to study this to work out a more sophisticated command line than that) For example: shell> mysql database < script.sql > output.tab which appears in section: 4.8.2 The Command-line Tool The DuBois book discusses batch mode and gives a shell script example on p76. Welling and Thomson discuss "file redirection" somewhat in passing on p195 and use it extensively, eg to set up new db/tbl definitions (if they detail it elsewhere I've failed to note it).

RE: Updating tables via cron
Try this:
echo "REPLACE INTO table_name (dr) VALUES ('0');" |
/usr/local/mysql/bin/mysql -u user -p password activity
or mysql -e "REPLACE INTO table_name (dr) VALUES ('0');" activity

Subject: Updating tables via cron
I tried to search the archives for this but I can't find it. (Not
saying
it isn't there just I could not find it.) I have a table that tracks
events on a monthly and daily basis. Currently I am resetting the
appropriate fields to 0 on a daily and monthly basis (not fun). Is there a
way to set a command in the cron table to do this for me
automatically? Here are the details.
db name: activity
daily field name: dr (needs to be reset to 0)
monthly field name: mr (same as above)
I know how to tell cron the date/time I want an event to trigger,
but I
don't know the syntax of the command to send. Any help would be
appreciated.
Thanks,
David

RE: Updating tables via cron
Here is a select statement, as example:
mysql -e "select * from user \G" mysql
Add user and password as required.
