Question

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         


        

Answer 1

For me it was the first time with Salesforce today and I came up with this in Java:

/**
 * @param o any class that extends {@link SObject}, f.ex. Opportunity.class
 * @return a list of all the objects of this type
 */
@SuppressWarnings("unchecked")
public  List getAll(Class o) throws Exception {
    // get the objectName; for example "Opportunity"
    String objectName= o.getSimpleName();

    // this will give us all the possible fields of this type of object
    DescribeSObjectResult describeSObject = connection.describeSObject(objectName);

    // making the query
    String query = "SELECT ";
    for (Field field : describeSObject.getFields()) { // add all the fields in the SELECT
        query += field.getName() + ',';
    }
    // trim last comma
    query = query.substring(0, query.length() - 1);

    query += " FROM " + objectName;

    SObject[] records = connection.query(query).getRecords();

    List result = new ArrayList();
    for (SObject record : records) {
        result.add((O) record);
    }
    return result;
}
