Question

我有一个这样的查询：此查询从T_Order_Header

获取数据

select F_Exhibitor,F_Stand
from T_Order_Header
where F_Exhibition='12004'

output
--------
F_exhibitor   F_stand
2477           C1
2488           C2
2489           C3

我有另一个这样的查询：这是从T_ExhibitorLocation

 select F_ExhibitorCode,F_Stand
 from T_ExhibitorLocation
 where F_ExhibitionCode='12004' 

output
--------
F_ExhibitorCode   F_stand
2477              C1
2488              c2
2489              B1

T_order_header表F_Exhibitor和T_exhibtor位置F_ExhibitorCode是相同的。

我想比较两个表并检查任何没有改变的立场。如果任何立场没有改变，我想表明。

Answer 1

试试这个

select toh.F_Exhibitor,toh.F_Stand
from T_Order_Header toh
INNER JOIN T_ExhibitorLocation tel
ON toh.F_exhibitor= tel.F_ExhibitorCode
WHERE toh.F_stand = tel.F_stand
AND toh.F_Exhibition='12004'

Answer 2

如果要添加指示值是否相等或应该检查的计算列，您可以使用CASE，如下所示：

$('#checkboxId').click(function () {
    //add code here
    });
