what is the best practice to write a trigger

sandeep sankhlasandeep sankhla
Hi Ravi,

Following are the best practises for triggers..

1. We should always have one trigger for one object...
2. We should make use of handler class instead of writting code inside trigger..
3. You can define different methods inhandler class based on event which you can call fro trigger..
4. Use recurrision handler to avoid the recurssion.
5. DOnt use DML inside forloop..

Please refer above link for more details...

Thanks,

1.Always try to have one trigger on one object rather than having multiple triggers.
2.Try to define the dml operations outside the loop (Bulkyfying),so it would not touch the governor limit, that means at maximum Total number of   DML statements issued are 150

3.Most of the times try to avoid recurrsion of the triggers (read about recurssive triggers)
4.if you do have a requirement that leads to recurssion of the triggers then define Static boolean variable within your trigger.
Let me know if you need further info about this.
