API Field Properties

Fields on objects represent the details of each object and are analogous to columns in a database table. Each field on each object has one or more of the following properties:

Property	Description
Autonumber	The API creates an autonumber.
Create	Value for the field can be specified during create using the API.
Defaulted on create	When created, a default value is supplied if no other value is specified.
Delete	Value for the field can be deleted using the API.
Filter	Can be used as filter criteria in a SOQL query FROM or WHERE clause.
Group	Can be included in the GROUP BY clause of a SOQL query (`true`) or not (`false`). Available in API version 18.0 and later.
idLookup	Can be used to specify a record in an upsert call. The Id field of each object has this property and some Name fields. There are exceptions, so check for the property in any object you wish to upsert.
Nillable	The field can contain a null value.
Query	The field can be queried with SOQL using the API.
Replicate	The value of the field can be replicated using the API.
Restricted picklist	A picklist that depends on the value of another picklist for the values it displays.
Retrieve	Value of the field can be retrieved using the API.
Search	Can be searched with SOSL using the API.
Sort	Indicates whether a query can sort on this field (`true`) or not (`false)`.
Update	Can be updated using the API.
