ApexTrigger

Represents an Apex trigger.

Note

Although Apex classes and triggers have the Create and Update field properties, a runtime exception occurs if you try to create or update them using the API. Instead, use the Force.com Migration Tool, the Salesforce user interface, or the Force.com IDE to create or update Apex classes or triggers.

Supported Calls

create(), delete(), describeSObjects(), getDeleted(), getUpdated(), query(), retrieve(), update(), upsert()

Fields

Field	Details
ApiVersion	Type double Properties Create, Filter, Sort, Update Description The API version for this trigger. Every trigger has an API version specified at creation.
Body	Type textarea Properties Create, Nillable, Update Description The Apex trigger definition. Limit: 32,000 characters.
bodyCrc	Type double Properties Create, Defaulted on create, Filter, Nillable, Sort, Update Description The CRC (cyclic redundancy check) of the class or trigger file.

LengthWithoutComments	Type int Properties Create, Filter, Group, Sort, Update Description Length of the trigger without comments
Name	Type string Properties Create, Filter, Group, Sort, Update Description Name of the trigger. Limit: 255 characters
NamespacePrefix	Type string Properties Filter, Group, Nillable, Sort Description The namespace prefix associated with this object. Each Developer Edition organization that creates a managed package has a unique namespace prefix. Limit: 15 characters. You can refer to a component in a managed package by using the `namespacePrefix__componentName` notation. The namespace prefix can have one of the following values: In Developer Edition organizations, the namespace prefix is set to the namespace prefix of the organization for all objects that support it. There is an exception if an object is in an installed managed package. In that case, the object has the namespace prefix of the installed managed package. This is the namespace prefix of the Developer Edition organization of the package developer. In organizations that are not Developer Edition organizations, NamespacePrefix is only set for objects that are part of an installed managed package. There is no namespace prefix for all other objects.
Status	Type picklist Properties Create, Filter, Group, Restricted picklist, Sort, Update Description The current status of the Apex trigger. The following string values are valid: `Active`—The trigger is active. `Inactive`—The trigger is inactive, but not deleted. `Deleted`—The trigger is marked for deletion. This is useful for managed packages, because it allows a class to be deleted when a managed package is updated. Note `Inactive` is not valid for ApexClass. For more information, see the Force.com Metadata API Developer's Guide.
TableEnumOrId	Type picklist Properties Create, Filter, Group, Nillable, Restricted picklist, Sort, Update Description Specifies the object associated with the trigger, such as Account or Contact.

UsageIsBulk	Type boolean Properties Create, Filter, Update Description Specifies whether the trigger is defined as a bulk trigger (`true`) or not (`false`). Note This field is not used for Apex triggers saved using Salesforce.com API version 10.0 or higher: all triggers starting with that version are automatically considered bulk, and this field will always return `true`.
