list<testrecord> recordcollection = new list<testrecord>(); recordcollection.add(new testrecord(id = 1,name = 'test',body = 'html')) recordcollection.add(new testrecord(id = 2,name = 'test2',body = 'html2'))  maintaining batches 3000 records set chunk of data updation.  if(recordcollection.count > 3000) {  == update record set in database using single update query.. } 

i have searched few of method bluck update below,
