DescribeSObjectResult

The name of the sObject that has a foreign key to the sObject being described.

In the DescribeSObjectResult, the fields property contains an array of Field objects. Each field represents a field in an API object. The array contains only the fields that the user can view, as defined by the user's field-level security settings.

Name	Type	Description
autonumber	boolean	Indicates whether this field is an autonumber field (true) or not (false). Analogous to a SQL IDENTITY type, autonumber fields are read only, non-createable text fields with a maximum length of 30 characters. Autonumber fields are read-only fields used to provide a unique ID that is independent of the internal object ID (such as a purchase order number or invoice number). Autonumber fields are configured entirely in the Salesforce user interface. The API provides access to this attribute so that client applications can determine whether a given field is an autonumber field.
byteLength	int	For variable-length fields (including binary fields), the maximum size of the field, in bytes.
calculated	boolean	Indicates whether the field is a custom formula field (true) or not (false). Note that custom formula fields are always read-only.
caseSensitive	boolean	Indicates whether the field is case sensitive (true) or not (false).
controllerName	string	The name of the field that controls the values of this picklist. It only applies if type is picklist or multipicklist and dependentPicklist is true. See About Dependent Picklists. The mapping of controlling field to dependent field is stored in the validFor attribute of each PicklistEntry for this picklist. See validFor.
createable	boolean	Indicates whether the field can be created (true) or not (false). If true, then this field value can be set in a create() call.
custom	boolean	Indicates whether the field is a custom field (true) or not (false).
defaultedOnCreate	boolean	Indicates whether this field is defaulted when created (true) or not (false). If true, then Salesforce implicitly assigns a value for this field when the object is created, even if a value for this field is not passed in on the create() call. For example, in the Opportunity object, the Probability field has this attribute because its value is derived from the Stage field. Similarly, the Owner has this attribute on most objects because its value is derived from the current user (if the Owner field is not specified).
defaultValueFormula	string	The default value specified for this field if the formula is not used. If no value has been specified, this field is not returned.
dependentPicklist	boolean	Indicates whether a picklist is a dependent picklist (true) where available values depend on the chosen values from a controlling field, or not (false). See About Dependent Picklists.
digits	int	For fields of type integer. Maximum number of digits. The API returns an error if an integer value exceeds the number of digits.
filterable	boolean	Indicates whether the field is filterable (true) or not (false). If true, then this field can be specified in the WHERE clause of a query string in a query() call.
formula	string	The formula specified for this field. If no formula is specified for this field, it is not returned.
htmlFormatted	boolean	Indicates whether a field such as a hyperlink custom formula field has been formatted for HTML and should be encoded for display in HTML (true) or not (false). Also indicates whether a field is a custom formula field that has an IMAGE text function.
idLookup	boolean	Indicates whether the field can be used to specify a record in an upsert() call (true) or not (false).
inlineHelpText	string	The text that displays in the field-level help hover text for this field. Note This property is not returned unless at least one field on the object contains a value. When at least one field has field-level help, all fields on the object list the property with either the field-level help value or null for fields that have blank field-level help.
label	string	Text label that is displayed next to the field in the Salesforce user interface. This label can be localized.
length	int	For string fields, the maximum size of the field in Unicode characters (not bytes).
name	string	Field name used in API calls, such as create(), delete(), and query().
nameField	boolean	Indicates whether this field is a name field (true) or not (false). Used to identify the name field for standard objects (such as AccountName for an Account object) and custom objects. Limited to one per object, except where FirstName and LastName fields are used (such as in the Contact object). If a compound name is present, for example the Name field on a person account, nameField is set to true for that record. If no compound name is present, FirstName and LastName have this field set to true.
namePointing	boolean	Indicates whether the field's value is the Name of the parent of this object (true) or not (false). Used for objects whose parents may be more than one type of object, for example a task may have an account or a contact as a parent.
nillable	boolean	Indicates whether the field is nillable (true) or not (false). A nillable field can have empty content. A non-nillable field must have a value in order for the object to be created or saved.
picklistValues	PicklistEntry[]	Provides the list of valid values for the picklist. Specified only if restrictedPicklist is true.
precision	int	For fields of type double. Maximum number of digits that can be stored, including all numbers to the left and to the right of the decimal point (but excluding the decimal point character).
relationshipName	string	The name of the relationship.
referenceTo	string[]	For fields that refer to other objects, this array indicates the object types of the referenced objects.
restrictedPicklist	boolean	Indicates whether the field is a restricted picklist (true) or not (false).
scale	int	For fields of type double. Number of digits to the right of the decimal point. The API silently truncates any extra digits to the right of the decimal point, but it returns a fault response if the number has too many digits to the left of the decimal point.
soapType	SOAPType	See SOAPType for a list of allowable values.
sortable	boolean	Indicates whether a query can sort on this field (true) or not (false).
type	FieldType	See FieldType for a list of allowable values.
unique	boolean	Indicates whether the value must be unique true) or not false).
updateable	boolean	Indicates whether the field is updateable (true) or not (false). If true, then this field value can be set in an update() call.

In the Field object associated with the DescribeSObjectResult, the type field can contain one of the following strings. For more information about field types, see Field Types.

The DescribeSObjectResult returns the fields property, which contains an array of fields whose value provides information about the object being described. One of those fields, soapType, contains one of the following string values. All of the values preceded by xsd: are XML schema primitive data types. For more information about the XML schema primitive data types, see the World Wide Web Consortium’s publication XML Schema Part 2: Data Types at: http://www.w3.org/TR/xmlschema-2/.

In the Field object associated with the DescribeSObjectResult, the picklistValues field contains an array of PicklistEntry properties. Each PicklistEntry can contain any one of the following string values. For more information, see Picklist Field Type.

A dependent picklist works in conjunction with a controlling field to filter its values. The value chosen in the controlling field affects the values available in the dependent picklist.

A dependent picklist can be any custom picklist or multi-select picklist field that displays available values based on the value selected in its corresponding controlling field. A controlling field can be any standard or custom picklist (with at least one and less than 200 values) or checkbox field whose values control the available values in one or more corresponding dependent fields.

In the following example, the controlling picklist Beverage has two values, which relate to the values of the dependent picklist Beverage Variety:

For each PicklistEntry that represents a value in a dependent picklist, the validFor attribute contains a set of bits. Each bit indicates a controlling field value for which the PicklistEntry is valid. Read the bits from left to right.

For more information on dependent picklists, see the “About Dependent Fields” topic in the Salesforce online help.
