使指定语句的下一个结果（结果集、行计数或输出参数）处于活动状态。
 注意:

|---|
|
无需调用 sqlsrv_next_result，批处理查询或存储过程返回的第一个（或唯一的）结果就已处于活动状态。
|
以下示例创建和执行一个存储过程，此存储过程将一个产品审核插入 Production.ProductReview 表，然后选择指定产品的所有审核。在执行此存储过程之后，在不调用sqlsrv_next_result 的情况下使用第一个结果（受此存储过程中的 INSERT 查询影响的行数）。通过调用 sqlsrv_next_result 使下一个结果（由此存储过程中的 SELECT 查询返回的行）可用，并通过使用 sqlsrv_fetch_array 来使用此结果。

建议使用规范语法来调用存储过程。有关规范语法的详细信息，请参阅 Calling a Stored Procedure（调用存储过程）。

在执行具有输出参数的存储过程时，建议先使用所有其他结果，然后再访问输出参数的值。有关详细信息，请参阅如何指定参数方向。
