# updateCharacterStream Method (java.lang.String, java.io.Reader)
[!INCLUDE[Driver_JDBC_Download](../../../includes/driver_jdbc_download.md)]

  Updates the designated column with a character stream value.  
  
## Syntax  
  
```  
  
public void updateCharacterStream(java.lang.String columnLabel,  
                                  java.io.Reader reader)  
```  
  
#### Parameters  
 *columnLabel*  
  
 A **String** that contains the column label.  
  
 *reader*  
  
 A Reader object.  
  
## Exceptions  
 [SQLServerException](../../../connect/jdbc/reference/sqlserverexception-class.md)  
  
## Remarks  
 This updateCharacterStream method is specified by the updateCharacterStream method in the java.sql.ResultSet interface.  
  
 This method passes Unicode characters from a Reader object to selected text and binary columns. This includes all text columns and **binary**, **varbinary**, **varbinary(max)**, **image**, and **xml** columns, but not **udt** columns.  
  
 Using this method for the **image**, **text**, and **ntext**[!INCLUDE[ssNoVersion](../../../includes/ssnoversion-md.md)] data types might impact performance.
