# DEFINE_COMMAND_EX
Specifies the command that will be used to create the rowset when using the [CCommand](../../data/oledb/ccommand-class.md) class. Supports Unicode and ANSI applications.  
  
## Syntax  
  
```  
  
DEFINE_COMMAND_EX(  
x  
,   
wszCommand  
 )  
  
```  
  
#### Parameters  
 *x*  
 [in] The name of the user record (command) class.  
  
 `wszCommand`  
 [in] The command string that will be used to create the rowset when using [CCommand](../../data/oledb/ccommand-class.md).  
  
## Remarks  
 The command string that you specify will be used as the default if you do not specify command text in the [CCommand::Open](../../data/oledb/ccommand-open.md) method.  
  
 This macro accepts Unicode strings, regardless of the application type. This macro is preferred over [DEFINE_COMMAND](../../data/oledb/define-command.md) because it supports Unicode as well as ANSI applications.  
  
## Example  
 See [BOOKMARK_ENTRY](../../data/oledb/bookmark-entry.md).  
  
## Requirements  
 **Header:** atldbcli.h
