Question

这是使用存储过程时的查询，但没有结果。但是当我单独使用过程中的查询时。它有结果。我希望此存储过程避免长查询字符串，然后将其传输到我的datagridview。我已经搜索了很多有关带有参数的存储过程的信息，这就是我如何构建此查询。

CALL BillingStorageParticulars(
1, '2019-06-16', '2019-06-30',
@entryid,
@contrno,
@type_code,
@evnt_in,
@evnt_out,
@freetime,
@storage_rate,
@lolo_rate,
@cleaning,
@rate_id,
@rate_validity,
@rendered_days
);

SELECT
@entryid AS entryid,
@contrno AS contrno,
@type_code AS type_code,
@evnt_in AS evnt_in,
@evnt_out AS evnt_out,
@freetime AS freetime,
@storage_rate AS rate,
@lolo_rate AS lolo,
@cleaning AS cleaning,
@rate_id AS rateid,
@rate_validity AS validity,
@rendered_days AS rendered;

这是我的程序

USE `ems_2019`;
DROP procedure IF EXISTS `BillingStorageParticulars`;
