    Hi Sakthidasan,

    A batch apex can be called from a class as well as from trigger code. But, we have to be very very carefull while calling a batch apex from trigger.

    In your Trigger code something like below :-

     

    // BatchClass is the name of batchclass
    BatchClass bh = new BatchClass();
    Database.executeBacth(bh);

    My only concern is that the Trigger would fire on the DML events and that would invoke the Batch.Do you want to run batch as many times as the Trigger would fire ?? Then you can proceed, but my personal openion is not to go with it.

    Please follow the below links on the same post:
