# CHANGE_TRACKING_CURRENT_VERSION (Transact-SQL)
[!INCLUDE[tsql-appliesto-ss2008-asdb-xxxx-xxx_md](../../includes/tsql-appliesto-ss2008-asdb-xxxx-xxx-md.md)]

  Returns a version that is associated with the last committed transaction. This version can be used when you enumerate changes by using [CHANGETABLE](../../relational-databases/system-functions/changetable-transact-sql.md).

## Syntax  
  
```  
  
CHANGE_TRACKING_CURRENT_VERSION ( )  
```  
  
## Return Type  
 **bigint**  
  
## Remarks  
 Returns NULL when change tracking is not enabled for the database.  
  
## Examples  
 The following example declares the local variable `@next_baseline` for storing the current version of tracked changes, and then uses the `CHANGE_TRACKING_CURRENT_VERSION()` function to obtain the value for the variable.  
  
```tsql  
DECLARE @next_baseline bigint;  
SET @next_baseline = CHANGE_TRACKING_CURRENT_VERSION();  
```
