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

  Invalidates the specified in-row text pointer, or all in-row text pointers, in the transaction. **sp_invalidate_textptr** can be used only on in-row text pointers. These pointers are from tables that have the **text in row** option enabled.  
  
||  
|-|  
|**Applies to**: [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] ([!INCLUDE[ssKatmai](../../includes/sskatmai-md.md)] through [current version](http://go.microsoft.com/fwlink/p/?LinkId=299658)).|

## Syntax  
  
```  
  
sp_invalidate_textptr [ [ @TextPtrValue = ] textptr_value ]  
```  
  
## Arguments  
 [ **@TextPtrValue=** ] *textptr_value*  
 Is the in-row text pointer that to be invalidated. *textptr_value* is **varbinary(**16**)**, with a default of NULL. If NULL, **sp_invalidate_textptr** invalidates all in-row text pointers in the transaction.  
  
## Return Code Values  
 0 (success) or 1 (failure)  
  
## Remarks  
 [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] allows for a maximum of 1,024 active valid in-row text pointers per transaction per database; however, a transaction spanning more than one database can have 1,024 in-row text pointers in each database. **sp_invalidate_textptr** can be used to invalidate in-row text pointers and, therefore, free space for additional in-row text pointers.  
  
 For more information about the text in row option, see [sp_tableoption (Transact-SQL)](../../relational-databases/system-stored-procedures/sp-tableoption-transact-sql.md).
