Codeigniter-SQL Server 2008：如何在存储过程中获取参数输出

Question

I've a procedure in SQL Server 2008

CREATE PROCEDURE dbo.testing
    @parm varchar(10),
    @parmOUT varchar(30) OUTPUT
AS
BEGIN
   SELECT @parmOUT = 'parm 1 ' + @parm
END 

and i have a query to access this procedure in Codeigniter frameword. i use sqlsrv_driver database.

$param1 = 'test';
$param2 = '1';
$this->db->query("dbo.testing ?,  ?", array($param1, $param2)); 

i've execute the procedure, but i can't retrieve 2nd parameter value ($param2).

Anyone have idea to get this 2nd parameter value??

thanks b4

Answer 1

In your Stored Procedure ,you are passing one input parameter and the specifying one output parameter . So the SP should be modified like the one below

ALTER PROCEDURE dbo.testing
@parm varchar(10),
@parmOUT varchar(30) OUTPUT
AS
BEGIN
SELECT  'parm 1 ' + @parm
END  

Now in order to execute the above SP you need to pass just one input parameter

 declare @out varchar(30)
 exec testing 'test', @parmOUT=@out OUTPUT

You will just retrieve the result as

 param1test

There is no second parameter which you can retrieve from your SP .The only value which you will get is the one which you have specified in your select query .

Answer 2

$sql = 'DECLARE @RETURNV VARCHAR(20)
EXEC dbo.testing ?, @parmOUT= @RETURNV OUTPUT
SELECT @RETURNV AS RETURNV';
$param = array(
  "This is first param"
);
$temp = $this->db->query($sql, $param);
$result = $temp->result_array();
echo "<pre>".print_r($result, true)."</pre>";
