运用Database Class里面的方法来操作数据库

运用类方法来操作数据库，并且捕获错误

Account[] accts = new List{
new Account(Name=’Account1’),
new Account()};

//这个是运用类方法来操作数据的
Database.SaveResult[] srList = Database.insert(accts, false);

// Iterate through each returned result
for (Database.SaveResult sr : srList) {
if (!sr.isSuccess()) {
// Operation failed, so get all errors
for(Database.Error err : sr.getErrors()) {
System.debug(‘The following error has occurred.’);
System.debug(err.getStatusCode() + ‘: ’ + err.getMessage());
System.debug(‘Fields that affected this error: ’ + err.getFields());
}
}
}
