# updateBytes Method (java.lang.String, byte)
[!INCLUDE[Driver_JDBC_Download](../../../includes/driver_jdbc_download.md)]

  Updates the designated column with an array of **byte** values given the column name.  
  
## Syntax  
  
```  
  
public void updateBytes(java.lang.String columnName,  
                        byte[] x)  
```  
  
#### Parameters  
 *columnName*  
  
 A **String** that contains the column name.  
  
 *x*  
  
 An array of **byte** values.  
  
## Exceptions  
 [SQLServerException](../../../connect/jdbc/reference/sqlserverexception-class.md)  
  
## Remarks  
 This updateBytes method is specified by the updateBytes method in the java.sql.ResultSet interface.  
  
 In a previous version of [!INCLUDE[jdbcNoVersion](../../../includes/jdbcnoversion_md.md)], you could use SQLServerResultSet.updateBytes to convert values between byte arrays and [!INCLUDE[ssNoVersion](../../../includes/ssnoversion-md.md)] data type **date**, **time**, **datetime2**, or **datetimeoffset**. Now, using this method with those data types will cause an exception indicating that the conversion is not supported.
