System.SObjectException: Invalid field

I do not understand why the following exception occurs:

System.SObjectException: Invalid field Opportunity.Account.Name for Opportunity

Here is the code:

        string dynamicSql = 'select Opportunity.Account.Name from Opportunity';
        for(sObject row: Database.query(dynamicSql)) {                   
            string analyzeType = String.valueOf(row.get('Opportunity.Account.Name'));
        }


Note: I am using the Database.Query because sql is generated on the fly which can be for other tables.

Hi,

Use the below code:

string dynamicSql = 'select Name,Account.Name from Opportunity';
for(Opportunity row: Database.query(dynamicSql)) {
string analyzeType = String.valueOf(row.Account.Name);
System.debug('analyzeType************ :'+analyzeType);
}

Thanks,

 string dynamicSql = 'select Account.Name from Opportunity';
        for(sObject row: Database.query(dynamicSql)) {                   
            string analyzeType = String.valueOf(row.get('Account.Name'));
        }

 

Try that and see if it works!

No, still error:

 

System.SObjectException: Invalid field Account.Name for Opportunity

Ok I dug a little deeper and here is what your rows contain (this is just one row)

 

15:56:07:033 USER_DEBUG [4]|DEBUG|Opportunity:{AccountId=001c0000008HrpSAAS, Id=006c00000037E57AAE}

 

As you can see there is no account.name.  What you may need to end up doing is gathering all the accountID's and then querying again on  the account object to grab the names.

}

That will not work, the query is not returning account.name at all so whatever syntax that is used, you can not get account.name out of an object that does not contain it.

Please execute the above code from Developer console.
it is working.

OH! I see the difference, nevermind, good catch!  Yes it does.

Thanks for the reply, the issue that I will have is the row.Account.Name is not in a string so I cannot change it on the fly depending on what I put in for the column.
