存储过程和sqlsrv_num_rows - 光标错误？

Question

有没有办法将sqlsrv_num_rows（）与存储过程一起使用？

基本上当我尝试使用此功能，我收到这些错误之一，这取决于光标i电源：

Array ([0] => Array ([0] => IMSSP [SQLSTATE] => IMSSP [1] => -50 [code] => -50 [2] => This function only works with statements that have static or keyset scrollable cursors. [message] => This function only works with statements that have static or keyset scrollable cursors.)) 

或

Array ([0] => Array ([0] => 01000 [SQLSTATE] => 01000 [1] => 16954 [code] => 16954 [2] => [Microsoft][SQL Server Native Client 10.0][SQL Server]Executing SQL directly; no cursor. [message] => [Microsoft][SQL Server Native Client 10.0][SQL Server]Executing SQL directly; no cursor.) [1] => Array ([0] => 01S02 [SQLSTATE] => 01S02 [1] => 0 [code] => 0 [2] => [Microsoft][SQL Server Native Client 10.0]Cursor type changed [message] => [Microsoft][SQL Server Native Client 10.0]Cursor type changed)) 

我花了一些时间尝试寻找这个问题的解决方案，但没有运气。

如何从使用SqlSrv的存储过程获取行计数？我将不得不手动循环遍历结果和$ count ++;我想避免这种情况。或者，有什么办法可以改变实际的存储过程来包含光标？我对游标不是很熟悉，所以我不知道这是否是解决方案。

预先感谢您！

看到这个：sqlsrv_num_rows() with stored procedures似乎没有什么比解决办法。

您可以在过程中捕获@@ ROWCOUNT并将其作为OUTPUT参数返回。

CREATE PROCEDURE YourProc 
(
    @param1 int 
    ,@param2 varchar(5) 
    ,@rowCountOf int OUTPUT 
) 
AS 

SELECT * FROM TABLE WHERE ... --returns result set 
SET @rowCountOf=@@ROWCOUNT  --set output variable to be the row count 
return 0 
GO 

或者您可以使用sp_executesql代替上述链接中所述。
