Question

不要认为IN子句可以接受具有多个值的绑定参数。甲骨文不能和几分钟而查询是

declare @setting varchar(max)

set @setting ='''Sales Entry Grid Cursor'',''Customer Mandatory'',''Coloum Uom'',''Show Marka'',''Show Discount Amount In Grid'',''Show Discount % In Grid'',''Calculation based on Weight *rate'''

存储过程为

 Select pageconfig_action from [RetailSoft].[dbo].[tbl_pageconfig] 
Where [PageConfig_settingsName] in(@setting)
 and PageConfig_CompanyId=1

结果为空

并直接在关键字

中传递字符串

Select pageconfig_action from [RetailSoft].[dbo].[tbl_pageconfig] 
    Where [PageConfig_settingsName] in('Sales Entry Grid Cursor','Customer Mandatory','Coloum Uom','Show Marka','Show Discount Amount In Grid','Show Discount % In Grid','Calculation based on Weight *rate')
     and PageConfig_CompanyId=1

然后结果就可以了

Answer 1

您需要将Setting设为表格，而不是varchar。
那么就不需要动态sql了，您可以像这样保持简单

declare @Setting table (name varchar(50))

insert into @Setting (name)
values ('Sales Entry Grid Cursor'), 
       ('Customer Mandatory'),
       ('Coloum Uom'),
       ('Show Marka'),
       ('Show Discount Amount In Grid'),
       ('Show Discount % In Grid'),
       ('Calculation based on Weight *rate')

Select pageconfig_action 
from   [RetailSoft].[dbo].[tbl_pageconfig] 
Where  [PageConfig_settingsName] in (select name from @setting)
and    PageConfig_CompanyId=1

Answer 2

在SQL SERVER 2016+中：

使用内置的string_split函数。请注意，不再需要多余的单引号：

DECLARE @setting varchar(max)

set @setting ='Sales Entry Grid Cursor,Customer Mandatory,Coloum Uom,Show Marka,Show Discount Amount In Grid,Show Discount % In Grid,Calculation based on Weight *rate'


Select pageconfig_action from [RetailSoft].[dbo].[tbl_pageconfig] 
Where [PageConfig_settingsName] in(SELECT value FROM string_split(@setting, ',') )
 and PageConfig_CompanyId=1

如果您运行的SQL Server早于SQL 2016，则@GuidoG的答案是一种更可取的方法

Answer 3

您误解了SQL Server中如何处理字符串。您拥有的字符串（'''Sales Entry Grid Cursor'',''Customer Mandatory'',''Coloum Uom'',''Show Marka'',''Show Discount Amount In Grid'',''Show Discount % In Grid'',''Calculation based on Weight *rate'''是一个文字值，而不是多个值。 IN不会针对它“工作”，因为它正在寻找一行包含PageConfig_settingsName的整个字符串值的行。

这里有2个选项。首先是分割您的字符串并进行比较：

SELECT pageconfig_action
FROM [RetailSoft].[dbo].[tbl_pageconfig]
     CROSS APPLY STRING_SPLIT(@setting, ',') SS
WHERE [PageConfig_settingsName] = SS.[value]
  AND PageConfig_CompanyId = 1;

请注意，您不需要每个utem周围的引号（除非它们的值确实包含这些引号）

如果您不在SQL Server 2016+上，请搜索delimitedsplit8k（如果您使用的是2008），或者如果您使用的是2012/2014，则请使用delimitedsplit8k_lead。

否则，您可以使用表值变量并分别传递每个值：

DECLARE @Setting table (setting varchar(255));
INSERT INTO @Setting (setting)
VALUES ('Sales Entry Grid Cursor'),
       ('Customer Mandatory'),
       ('Coloum Uom'),
       ('Show Marka'),
       ('Show Discount Amount In Grid'),
       ('Show Discount % In Grid'),
       ('Calculation based on Weight *rate');

SELECT P.pageconfig_action
FROM [RetailSoft].[dbo].[tbl_pageconfig] P
     JOIN @Setting S ON S.setting = P.[PageConfig_settingsName]
WHERE P.PageConfig_CompanyId = 1;

使用in关键字的sql服务器传递字符串数组查询
