Re: bash powered MySQL Queries
I just wanted to know what would be the easiest way to retrieve simple data from a MySQL database from a bash script. Easiest way I've used to do it is: mysql EOQ select count(1) from tables; EOQ Which allows you to feed random queries to mysql from a bash script.

I do this a lot - just construct the query and dump it into a file from within the script, eg: echo select * from widgets where colour = 'red'; /tmp/query Then pipe the query into the mysql command line client and the result is echoed to stdin: $RESULT=`mysql -u user -ppassword widget_sales /tmp/query` and the variable $RESULT contains the result of your query.

Thank you all for your replies. I think that ShellSQL is really the thing I am looking for.

Re: bash powered MySQL Queries
Forgive me for blowing my own trumpet here. The advantage with ShellSQL over this method is 1 - The output is not cluttered with headers, and a means exist to easily separate fields when there is more than one column or row in the query. 2 - The connection is persistant, whereas running mysql for each command will open and close a connection with all the overhead that comes with that. ShellSQL also enables you to do transactions begin and commit at the beginning and end of the script.

Funny you should mention that May I guide you to my recent announcment of ShellSQL 0.7 - web page at http://www.edlsystems.com/shellsql - a utility to do just as you want (I think) released under GPL.
