Change status automatically using trigger from database when system date and date(from database) are equal

My table is-:


Id Status Date
1 false 2015-06-25
2 false 2015-06-25
3 false 2015-06-26
4 false 2015-06-26

If system date will be '2015-06-25' then using trigger status of Id:1 and 2 will be true and if system date will be '2015-06-26' then it will change the status false to true.

Can you explain it more clearer? What do you want to do? Do you want to update the status column using a trigger when the system date and date in the row matches?

when system date change after that check Date value match the system date then status value to automatically change.

Right! The trigger will only work for some events like INSERT , UPDATE or DELETE etc. For your requirements you may have to run a job in the SQL server daily to check the system date and any match in the rows then update the status.

yup, and if your using express edition then you can do it with scheduled tasks, batch files and the sqlcmd command, prob. run it at 00:01 everyday....

oops... mySQL, assuming your on a 'nix machine you do it with a cron job

When you say "system date" do you mean it is another day (in real life) - but nothing has changed on this table?
If so then a trigger is not what you need
