Update Account information on task

 i need to write a apex trigger to achieve this - 
When a task is created related to opportunity or contact, i want to stamp the related account info in a text field. 
But i will get only related-to Id, how can i get the account information from the related-to ID

Someone please help me,

Thanks in advance

Where do you want to persist account's info (another object perhaps) and which information would like to persist?

Hi Sindhu,

If you want to update a field on task with account field try the following code

trigger test on task (before insert,before update) {
    Set<Id> oppIds = new Set<Id>();
    Set<Id> contctIds = new Set<Id>();
    Map<Id,Opportunity> accoutnWithOppId = new Map<Id,Opportunity>();
    Map<Id,Contact> accoutnWithContctId = new Map<Id,Contact>();
    for (Task t : Trigger.new) {
            if (t.WhatId != null && string.valueof(t.WhatId).startsWith('006') ) {
            else if(t.WhoId != null && string.valueof(t.WhoId).startsWith('003')){
            for(Opportunity opp:[SELECT Id,AccountId,Account.Name,Account.Active__c FROM Opportunity WHERE Id IN : oppIds]){
            for(Contact con:[SELECT Id,AccountId,Account.Name,Account.Active__c FROM Contact WHERE Id IN : contctIds]){
        for (Task t : Trigger.new) {
            if (t.WhatId != null && string.valueof(t.WhatId).startsWith('006') && accoutnWithOppId != null && accoutnWithOppId.get(t.WhatId) != null) {
                t.Account_Name__c = accoutnWithOppId.get(t.WhatId).Account.Name;    
            else if(t.WhoId != null && string.valueof(t.WhoId).startsWith('003') && accoutnWithContctId != null && accoutnWithContctId.get(t.WhoId) != null){
               t.Account_Name__c = accoutnWithContctId.get(t.WhoId).Account.Name;


NOTE: Fetch the fields you want from account in the query. I have taken Account.Name as example
