Salesforce-列表没有返回行

Question

When i checked in Database the same query returning 18 rows, but in my Apex class it is retuning zero rows as in

 List<Account> accList=[SELECT Name,Id,ShippingStreet,ShippingState,ShippingCountry,ShippingCity,ShippingPostalCode
                           FROM Account];
 System.debug('accList size:'+accList.size());

Please check their snapshots attached below,

Please tell me the error happening in my code.

Answer 1

Finally I have resolved the issue. I am running those statements in a apex Test class, I forget to include the insert statements for the coresponding records, after adding the below statements to my code,

    Account acc=new Account(Name='test',ShippingStreet='Test address');
    insert acc;

Resolved my issue.
