sqlsrv_next_result

下載 PHP 驅動程式

讓指定陳述式的下一個結果 (結果集、資料列計數或輸出參數) 成為作用中。

注意

批次查詢或預存程序所傳回的第一個 (或唯一) 結果為作用中,而不需要呼叫 sqlsrv_next_result

語法

  
sqlsrv_next_result( resource $stmt )  

參數

$stmt:已執行且下一個結果已成為作用中的陳述式。

傳回值

如果下一個結果已成功成為作用中,將會傳回布林值 true 。 如果在讓下一個結果成為作用中時發生錯誤,則傳回 false 。 如果沒有其他結果可供使用,則傳回 null

範例 1

下列範例會建立並執行一個預存程序,將產品評論插入 Production.ProductReview 資料表中,然後選取指定產品的所有評論。 執行預存程序之後,將會取用第一個結果 (預存程序中的 INSERT 查詢所影響的資料列數目),而不會呼叫 sqlsrv_next_result。 下一個結果 (預存程序中的 SELECT 查詢所傳回的資料列) 可藉由呼叫 sqlsrv_next_result 成為可用結果,並可透過 sqlsrv_fetch_array 加以取用。

注意

使用標準語法呼叫預存程序,是建議的做法。 如需標準語法的詳細資訊,請參閱呼叫預存程序

此範例假設本機電腦上已安裝 SQL Server 和 AdventureWorks 資料庫。 從命令列執行範例時,所有輸出都會寫入至主控台。

執行具有輸出參數的預存程序時,建議您先取用所有其他結果,再存取輸出參數的值。 如需詳細資訊,請參閱 如何:使用 SQLSRV 驅動程式指定參數方向

範例 2

下列範例會執行一個批次查詢,擷取指定產品識別碼的產品評論資訊、插入產品的評論,然後再次擷取指定產品識別碼的產品評論資訊。 新插入的產品評論將包含在批次查詢的最終結果集內。 此範例會使用 sqlsrv_next_result ,從批次查詢的一個結果移至下一個。

注意

批次查詢或預存程序所傳回的第一個 (或唯一) 結果為作用中,而不需要呼叫 sqlsrv_next_result

此範例會使用 AdventureWorks 資料庫的 Purchasing.ProductReview 資料表,並假設此資料庫已安裝在伺服器上。 從命令列執行範例時,所有輸出都會寫入至主控台。
