now iam learning stage in batch how to run the above batch program,i save this apex program in my developer instance with out errors but i dnt knw how to run and how to get output


Create New Schedular Class to call your batch.

But simplaest way is Go to Apex Classes ---> Scheduled Apex button

Click on it and Select your Batch class and Time when to execute your batch.

If you want to check your batch run or not  then go  to  Monitoring Section and in that go to Scheduled get information from there whether your batch class run or not?


HI arjunsf

just try this with snippet in debuglog:-

id usrid='00590000000iedd';
String query='SELECT Id, Name, Ownerid FROM Account WHERE ownerid=\'' +usrid+ '\'';
deleteAccounts reassign = new deleteAccounts(query);

if you want to schedule the batch class then use system.schedule

String sch = '0 0 * * * ?';
system.schedule('SCheduled Job',sch,reassign);
