How do you run a single query through mysql from the command line?
mysql -uroot -p -hslavedb.mydomain.com mydb_production -e "select * from users;"
From the usage printout:
-e,--execute=name
Execute command and quit. (Disables--forceand history file)
mysql -u <user> -p -e 'select * from schema.table'
(Note the use of single quotes rather than double quotes, to avoid the shell expanding the * into filenames)
here's how you can do it with a cool shell trick:
mysql -uroot -p -hslavedb.mydomain.com mydb_production <<< 'select * from users'
'<<<' instructs the shell to take whatever follows it as stdin, similar to piping from echo.
use the -t flag to enable table-format output
If it's a query you run often, you can store it in a file. Then any time you want to run it:
mysql < thefile
(with all the login and database flags of course)
