Your find() method isn't quite right.

 

1. You define the method as returning a single phonebook (should be phonebook__c, with "__c" if phonebook is a custom object) object, but then it returns a list of phonebook__c objects.

 

2. Your SOQL query is missing the "where" keyword.

 

Also (and this is more a matter of style and readability than strict correctness), try to use the same case when refering to variable names. For example, your code uses both allPhoneBookEntries and AllPhoneBooKEntries. Pick one and use it consistently.

 

This would be more correct:

 

 

static List<Phonebook__c> find() {
List<Phonebook__c> allPhoneBookEntries =
[select Name, Surname__c, Telephone_number__c
from Phonebook__c
where Name ='Russe'];
return allPhoneBookEntries;
}

It would look like this:

 

List<phonebook__c> allPhoneBookEntries = [select Name, Surname__c, Telephone_number__c from phonebook__c where Name = 'Russel'];

i write an apex class like this :

 

global class SearchContact

{

         

               static    phonebook find()

               {

 

                    List<phonebook__c> allPhoneBookEntries =[select Name, Surname__c, Telephone_number__c

                                                                                         from phonebook__c Name ='Russe' ];

                    return AllPhoneBooKEntries;

                }

}

 

That's rigth?

Now, 'd like to use this class like a webservice in order to retrieve date from outer the salesforce platform.

can i do it by the apex class above?

Tnx for reply
