Retrieving Data

Data Model and the Force.com Platform

§  sObject: –  Table-like data structure

•  Records

•  Fields

–  Extensible

–  Queryable/Updatable

–  Relationships

§  Automatic Features: –  User Interface

–  Security •  CRUD

•  Field-level

•  Record-level (ACL)

–  REST & SOAP APIs

–  Mobile

Standard Data Model

§  Standard Objects –  Account

–  Contact

–  Lead

–  Opportunity

–  Case

–  …

§  Standard Fields –  Id

–  Name

–  CreatedBy/Date

–  LastModifiedBy/Date

–  OwnerId

–  IsDeleted

–  …

Extensible Data Model

§  Custom Objects –  Workshop__c

–  Room__c

–  …

§  Custom Fields –  Status__c

–  Type__c

–  Start_Time__c

–  End_Time__c

–  …

Relationships: The Predefined Join

§  RDBMS –  Join at runtime

with SQL or view

§  Force.com –  Predefined join

at design-time

–  Similar to integrity constraints

Master-Detail Lookup

Relationship Types

Never Optional

Cascade Clear Field/Block/Cascade*

Nullability

Delete Behavior

Child Inherits from Parent Independent Parent/Child

2 25

Record Sharing Access

Max Allowed Fields

Demo Use Case: –  Workshops and Rooms

SOQL

§  Salesforce Object Query Language

§  SQL-like syntax

§  Queries the Force.com Object Layer

§  Used in: –  Apex

–  Developer Tools (Developer Console, Eclipse, Workbench, …)

–  API (REST, SOAP, Bulk, …)

From SQL to SOQL

§  At first may look familiar

§  Important differences

§  Learn the differences

§  Use good data design practices

From SQL to SOQL: The Familiar Bits

§  Table-like structure

§  Similar query syntax

§  Indexed

§  Transactional

§  Triggers

SELECT Id, Name, Capacity__c FROM Room__c WHERE Capacity__c > 10

From SQL to SOQL: Immediate Differences

§  No select *

§  No views

§  SOQL is read-only

§  Limited indexes

§  Object-relational mapping is automatic

§  Schema changes protected

From SQL to SOQL: Differences To Learn

§  sObjects are not actually tables – multi-tenant environment

§  Relationship metadata –  Management of referential integrity

–  Predefines joins

–  Relationship query syntax

§  Query usage explicitly metered –  API Batch Limits

–  Apex Governor Limits

Relationship Query: Child to Parent

SELECT Id, Name, Room__c, Room__r.Id, Room__r.Capacity__c

FROM Workshop__c WHERE Status__c = ‘Open’

[ { "Id": "a0145000000aBf4AAE", "Name": "Yoga for Beginners", "Room__c": "a00vn000000dU3dAAE", "Room__r": { "Id": "a00vn000000dU3dAAE", "Capacity__c": 10 } }, { "Id": "a0145000000aBf4AAE", "Name": "Yoga for Beginners", "Room__c": "", "Room__r": {} }, ... ]

Relationship Query: Parent to Child

SELECT Id, Name, (SELECT Id, Status__c FROM Workshops__r) FROM Room__c WHERE Capacity__c > 10

[ { "Id": "a00vn000000dU3dAAE", "Name": "Salon 1 West", "Workshops__r": [ { "Id": "a0145000000aBf4AAE", "Status__c": "Open" }, { "Id": "a0145000000aBd4AAE", "Status__c": "Full" } ] }, ... ]

Querying for Intersection

Select Id, Name, Room__r.Name, Room__r.Capacity__c FROM Workshop__c WHERE Room__r.Capacity__c > 8

[ { "Id": "a0145000000aBf4AAE", "Name": "Yoga for Beginners", "Room__c": "a00vn000000dU3dAAE", "Room__r": { "Id": "a00vn000000dU3dAAE", "Capacity__c": 10 } }, {...}, ... ]

Aggregate Queries

SELECT COUNT(Id) rmCount, MAX(Capacity__c) maxRmCap, Configuration__c FROM Room__c GROUP BY Configuration__c

[ { "rmCount": 4, "maxRmCap": 6, "Configuration__c": "Classroom" }, { "rmCount": 2, "maxRmCap": 10, "Configuration__c": "Theatre" }, ... ]
