Question

我尝试在打开的查询中传递日期变量，但它显示错误，如

“+ +附近的语法不正确”

这是我的问题：

DECLARE @fromdt DATETIME = '2018-04-07';
 DECLARE @EndDate1 DATETIME = '2018-04-07';
    Select * from openquery(TIMEV,
       'SELECT REPLACE(LTRIM(REPLACE(badgenumber,"0"," "))," ","0") badgenumber,
checktime as dt
from checkinout a 
join USERINFO c on c.userid=a.userid  
        WHERE checktime >= '''''+CONVERT(CHAR(10), @fromdt, 120)+'''''  AND ''''' + CONVERT(CHAR(10), @EndDate1, 120) + ''''' ')

我被困在这里。谢谢你提前......

OPENQUERY documentation明确说：

OPENQUERY不接受其参数的变量。

因此，使用来自this site的技巧，您应该可以这样做：

DECLARE @fromdt DATETIME = '2018-04-07';
DECLARE @EndDate1 DATETIME = '2018-04-07';

DECLARE @query nvarchar(max) = 
'SELECT * FROM OPENQUERY(TIMEV,
    '' SELECT REPLACE(LTRIM(REPLACE(badgenumber,"0"," "))," ","0") badgenumber,
       checktime AS dt
       FROM checkinout a 
         JOIN USERINFO c on c.userid=a.userid  
       WHERE checktime >= ''''' + CONVERT(CHAR(10), @fromdt, 120) + '''''  AND ''''' + CONVERT(CHAR(10), @EndDate1, 120) + ''''' ''
)';

EXEC(@query);
