[ NOT ] boolean_expression  
```  
  
[!INCLUDE[sql-server-tsql-previous-offline-documentation](../../includes/sql-server-tsql-previous-offline-documentation.md)]

## Arguments
 *boolean_expression*  
 Is any valid Boolean [expression](../../t-sql/language-elements/expressions-transact-sql.md).  
  
## Result Types  
 **Boolean**  
  
## Result Value  
 NOT reverses the value of any Boolean expression.  
  
## Remarks  
 Using NOT negates an expression.  
  
 The following table shows the results of comparing TRUE and FALSE values using the NOT operator.  
  
||NOT|  
|------|---------|  
|**TRUE**|FALSE|  
|**FALSE**|TRUE|  
|**UNKNOWN**|UNKNOWN|  
  
## Examples  
 The following example finds all Silver colored bicycles that do not have a standard price over $400.  
  
```sql  
-- Uses AdventureWorks  
  
SELECT ProductID, Name, Color, StandardCost  
FROM Production.Product  
WHERE ProductNumber LIKE 'BK-%' AND Color = 'Silver' AND NOT StandardCost > 400;  
GO  
```  
  
 [!INCLUDE[ssResult](../../includes/ssresult-md.md)]  
  
 ```
 ProductID   Name                     Color         StandardCost
 ---------   -------------------      ------      ------------
 984         Mountain-500 Silver, 40  Silver        308.2179
 985         Mountain-500 Silver, 42  Silver        308.2179
 986         Mountain-500 Silver, 44  Silver        308.2179
 987         Mountain-500 Silver, 48  Silver        308.2179
 988         Mountain-500 Silver, 52  Silver        308.2179

## Examples: [!INCLUDE[ssSDWfull](../../includes/sssdwfull-md.md)] and [!INCLUDE[ssPDW](../../includes/sspdw-md.md)]  
 The following example restricts results to `SalesOrderNumber` to values starting with `SO6` and `ProductKeys` greater than or equal to 400.  
  
```sql  
-- Uses AdventureWorks  
  
SELECT ProductKey, CustomerKey, OrderDateKey, ShipDateKey  
FROM FactInternetSales  
WHERE SalesOrderNumber LIKE 'SO6%' AND NOT ProductKey < 400;
