| Name | Description | |
|---|---|---|
![]() | ColumnCount | Gets the number of columns contained by the data table bound to the trigger. This property is read-only. |
![]() | EventData | Gets the event data specific to the action that fired the trigger. |
![]() | TriggerAction | Indicates what action fired the trigger. |
| Name | Description | |

![]() | Equals(Object^) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |

![]() | GetType() | |
![]() | IsUpdatedColumn(Int32) | Returns true if a column was affected by an INSERT or UPDATE statement. |

The contextual information provided includes the type of action that caused the trigger to fire, which columns were modified in an UPDATE operation, and, in the case of a data definition language (DDL) trigger, an XML EventData structure (see "Transact-SQL Reference" in SQL Server Books Online) that describes the triggering operation.
An instance of SqlTriggerContext is available from the SqlContext class, when the code is running inside a trigger through the TriggerContext property.
The following example shows a SqlTriggerContext object being used to determine if an Insert action occurred. If a row was inserted into the user's table, the user name and real name are retrieved from the inserted row and then added to the UserNameAudit table.
