# sys.trace_event_bindings (Transact-SQL)
[!INCLUDE[tsql-appliesto-ss2008-xxxx-xxxx-xxx-md](../../includes/tsql-appliesto-ss2008-xxxx-xxxx-xxx-md.md)]

  The **sys.trace_event_bindings** catalog view contains a list of all possible usage combinations of events and columns. For each event listed in the **trace_event_id** column, all available columns are listed in the **trace_column_id** column. Not all available columns are populated each time a given event occurs. These values do not change for a given version of the [!INCLUDE[ssDEnoversion](../../includes/ssdenoversion-md.md)].  
  
 For a complete list of supported trace events, see [SQL Server Event Class Reference](../../relational-databases/event-classes/sql-server-event-class-reference.md).  
  
> [!IMPORTANT]  
>  [!INCLUDE[ssNoteDepFutureAvoid](../../includes/ssnotedepfutureavoid-md.md)] Use Extended Event catalog views instead.  
  
|Column name|Data type|Description|  
|-----------------|---------------|-----------------|

|**trace_column_id**|**smallint**|ID of the trace column. This column is also in the **sys.trace_columns** catalog view.|
