I'm using a shared webhosting and there's no option to enable the MySQL event scheduler in PhpMyAdmin. The support told me to use the cpanel cron job section instead, but it requires a linux command and I have found nothing of help for this issue.
How can I make the cpanel cron job execute this mysql command every hour?
UPDATE `users` SET online = `0`
You need shell or php script with mysql command, smth like this:
#!/bin/sh
/usr/bin/mysql -h "server-name" -u "mysql_user" "-pSECRET" -e "UPDATE `users` SET online = `0`" database_name
Detailed CPanel cron job setup can be found here.

We have a queueing system that was developed by our previous developer, and the truncate command was manually executed to the mysql query. We cant use event scheduler on cpanel so the best option we have is to use cronjob. however, we have no idea on how to execute linux command.
Can someone help me to make a linux query for this?
TRUNCATE TABLE counter_logs_vxphl;
Try to execute the command using the following command, replace {USER} with the username and {PASSWORD} with the password, if you want to specify the host just add -h {HOSTNAME}
mysql -u {USER} -p{PASSWORD} -e "TRUNCATE TABLE counter_logs_vxphl;" > mysql-truncate.log
I am learning how to use mysql with Cloud9, I have a script used to create a default database and tables and loading sample data into the new database. How do I use the mysql-ctl tool to execute a script file?
It connects to a database just fine and I can execute ad-hoc queries without an issue.
You cannot use mysql-ctl to execute the script (you can see the source code running less $(which mysql-ctl) but you can use the usual mysql client command:
mysql -h 127.0.0.1 -u username < yourfile.sql
When you are in 'mysql-ctl' just run
source file_name.sql and your script will run.
I have a problem with a shell script:
I am trying to inject data from a source file containing MySQL queries into a data base. Here are the relevant lines of my shell script:
mysql -u root
source /usr/local/insert.sql;
quit;
For example I am running the file as ./insertfile and it is running smoothly but when it comes to data insertion in MySQL it is logging into MySQL using the mysql -u root command but the remaining operations (source /usr/local/insert.sql; and quit;) are not being executed. When I quit MySQL manually it tries to execute the rest of the command from my insert.sql file.
So please help me use the right shell script so that I can insert the queries from the source file.
One way to do that would be
mysql -u root --execute="source /usr/local/insert.sql; quit;"
It seems that your import hangs !
Check for lock on your database.
show processlist;
Run FLUSH TABLES to release any possible locks and then run your import command.
if source command hangs again :
Enter your myslq server
drop database insert;
create database insert
exit the mysql server and run:
mysqldump -u -p database-name < dump.sql
Thanks for your help. I have tried adding your line in my script and it was primarily giving some errors then I changed the command like below -
mysql -u root --execute="source /usr/local/insert.sql; \q"
Above line helped me to execute my command.
Thanks to all for being this much helpful.

On a windows machine, every day i have to login to mysql via phpmyadmin, go to a particular table and run the same sql command to do some cleanup.
I want to automate this process without setting up a TRIGGER.....is there a command prompt solution for doing this, or an automatic process that can be simply run from a desktop shortcut?
Write a script Run.bat and copy the following contents in it:
mysql -h localhost -u root -ppassword -D database_name -e "cleanup command".
Schedule this command in your windows scheduler.
If you have multiple cleanup commands, then add them in a sql file and then schedule the following command:
mysql -h localhost -u root -ppassword -D database_name < path_to_sql_file
For windows you could use the task scheduler. You might not be able to get it to login to phpMyAdmin though. Perhaps cmd line for mysql?
I am trying to create a batch script that would connect to a mySQL database and issue a delete command:
#echo off
echo Resetting all assessments...
mysql -hlocalhost -urdfdev -p%1 rdf_feedback
delete from competency_question_answer;
I will run this script providing the password as a command-line argument, but all this script does is, connects to the database, and the mysql> prompt will be shown. After I exit from mysql, the rest of the batch commands get to execute (and fail, no surprise).
How can I pass the SQL commands from the batch script to the mysql console? Is this even possible?
You need to use command line tools. I don't know if there exists any for MySQL but for SQL there is SQLCMD and for Oracle there is OSQL.
What you can also do is something like this.
mysql -uuser -ppass < foo.sql
Where foo.sql is the commands you want to execute.
You may need to connect multiple times:
#echo off
echo Resetting all assessments...
mysql -hlocalhost -urdfdev -p%1 rdf_feedback -e delete from competency_question_answer;
Alternatively, you should be able to put all your commands in a separate file such as input.sql and use:
mysql -hlocalhost -urdfdev -p%1 rdf_feedback <input.sql
echo "delete from competency_question_answer;" | mysql -hlocalhost -ur... etc.
Putting multiple sets of commands into .sql batch files works best, and you can execute multiples of these in the .bat file.
