I was going through the SOQL documentation , but couldn\'t find query to fetch all the field data of an entity say , Account , like
select * from Account
I used following to get complete records-
query_all("Select Id, Name From User_Profile__c")
To get complete fields of record, we have to mention those fields as mentioned here- https://developer.salesforce.com/docs/atlas.en-us.soql_sosl.meta/soql_sosl/sforce_api_calls_soql_select.htm
Hope will help you !!!
