Question

我有一个PROCEDURE，它接受一个布尔输入：

 `get_storage_choices_expanded`(IN usage_total INT(11), IN no_request1 INT(8), IN no_request2 INT(8), IN reduced_redundancy_storage boolean)

但是当我使用它时：

call get_storage_choices_expanded(10,1,2,true);
select * from storage_choices_expanded
;

生成的结果与我测试过的相同选择查询不匹配。 e.g。

(select *, 
    usage_each_plan * if(true,reduced_redundancy_storage, standard_storage) as price_storage, 
    concat_ws(' ',`Provider Name`,`Name`,`region_name`) as group_name,
    1 * request_group1_unit as "Number of Type1 Requests",
    2 * request_group2_unit as "Number of Type2 Requests",
    (1 * request_group1_price) as price_request1,
    (2 * request_group2_price) as price_request2
from 
  (SELECT *, 
    ( if((quota_band_high is not NULL) and 10>quota_band_high, quota_band_high, 10) - quota_band_low) as usage_each_plan
  FROM `cloud`.`storage_service_price`
  where 10 > quota_band_low and reduced_redundancy_storage > if(true,0, -1)
  ) as storage_usage_each_plan
)

完整代码如下：

    CREATE DEFINER=`root`@`localhost` PROCEDURE `get_storage_choices_expanded`(IN usage_total INT(11), IN no_request1 INT(8), IN no_request2 INT(8), IN reduced_redundancy_storage boolean)
    BEGIN

    drop table if exists `cloud`.`storage_choices_expanded`;
    CREATE TEMPORARY TABLE `cloud`.`storage_choices_expanded` AS

      (select *, 
          usage_each_plan * if(reduced_redundancy_storage,reduced_redundancy_storage, standard_storage) as price_storage, 
          concat_ws(' ',`Provider Name`,`Name`,`region_name`) as group_name,
          no_request1 * request_group1_unit as "Number of Type1 Requests",
          no_request2 * request_group2_unit as "Number of Type2 Requests",
          (no_request1 * request_group1_price) as price_request1,
          (no_request2 * request_group2_price) as price_request2
      from 
        (SELECT *, 
          ( if((quota_band_high is not NULL) and usage_total>quota_band_high, quota_band_high, usage_total) - quota_band_low) as usage_each_plan
        FROM `cloud`.`storage_service_price`
        where usage_total > quota_band_low and reduced_redundancy_storage > if(reduced_redundancy_storage,0, -1)
        ) as storage_usage_each_plan
      ) 


    ;
    END

我试图用bool，bit，TINYINT（1）替换boolean，但它似乎没有任何区别。

可以调用并运行该过程而不会出现错误，但结果是错误的。调用过程返回reduced_redundancy_storage值== 0的行，这是不正确的，因为它应该是＆gt; 0

Answer 1

我认为这里的问题是您在存储过程中定义了一个参数，该数据库中存在与该字段相同的名称。检查是否存在名称为“reduced_redundancy_storage”的字段。

MySQL的过程布尔输入无法按预期工作
