Cron job to start on a dynamic time using MySQL queries -


imagine i'm performing several overnight jobs across different databases , want predefine different starting times per db stored in control table in mysql.

is there way start cron job based on returned value of mysql query?

to make myself clear, imagine table

client_name | batch_start_time
"client a" | 0:30
"client b" | 3:30
"client c" | 5:00

i want able tune batch times without editing crontab

thanks
