Hi Nikita,

Please try below code : 
trigger ValidateOrder on Order (before insert) 
{
   for(Order occ : Trigger.new)
   {
		Account acc = [Select id,Hard_Block__c from Account where  id=:occ.Accountid];
		if(acc.Hard_Block__c == True)
		occ.addError(' This Order Cannot be created' );
   }
}

Hi Nikita,

It's not a best practice to write SOQL in for loop as this will hit the governer limit of 100 SOQLs in one transaction if more than 100 records will be imported in Order object and will lead to failures. Please find the below mentioned code:
  
trigger ValidateOrder on Order (before insert) 
{
   Set<Id> setAccId = new Set<Id>();
   for(Order occ : Trigger.new)
   {		
		if(occ.AccountId!=NULL)
			setAccId.add(occ.AccountId);
   }
   
   Map<id, Account> mapIdToAcc = new Map<Id,Account>([select Id from Account where Hard_Block__c = true AND AccountId IN : setAccId]);
   
   for(Order occ : Trigger.new)
   {
		if(occ.AccountId!=NULL && mapIdToAcc.containskey(occ.AccountId))
			occ.addError('This Order Cannot be created');
   }
}

Hi Nikita,
First: You are using Before Insert and checking for Id of Order, as the Id of order will not be available because it has not been created yet. Hence your code will never get executed.
Second: What is the need of "occ = [Select Accountid from Order where id =: occ.id];" as you have the date already in occ.
Third: Never write SOQL in for loop. Try Sets for fetching the Account Ids in your Loop and the query on the set to get the Account Detail.

Hope this helps.
