I'm back with another question. I've been tinkering with this for 1 and a half days now and still no luck. So I have the tables below.
我回来了另一个问题。我一直在修补这个1天半,但仍然没有运气。所以我有下表。
Table1
Field1 Field2 Field3 Field4 Field5
DR1 500 ID1 Active TR1
DR2 250 ID2 Active TR1
DR3 100 ID1 Active TR1
DR4 50 ID3 Active TR1
DR5 50 ID1 Cancelled TR1
DR6 150 ID1 Active TR2
Table2
Field1 Field3
ID1 Chris
ID2 John
ID3 Jane
Table3
Field1 Field2
TR1 Shipped
TR2 Pending
I currently can achieve this result.
我目前可以实现这个结果。
Name Total
Chris 650 3
John 250 1
Jane 50 1
using this sql statement
使用这个sql语句
SELECT t2.Field3 as Name , SUM(t1.Field2) as Total
FROM [Table1] t1 INNER JOIN [Table2] t2 ON t1.Field3 = t2.Field1
GROUP BY t2.Field3
However, I'd like to achieve this result shown below.
但是,我想实现下面显示的结果。
Chris 600 2
John 250 1
Jane 50 1
I'd like to check Table3 first if it has a 'Shipped' Field2 then it includes everything in Table1 with 'Active' Field4. It should not include 'Cancelled' Field4. And if Table3 has a Field2 of Pending, it should also not include it. I'd appreciate any little help. Thank you.
我想首先检查Table3,如果它有一个'Shipped'Field2,那么它包含Table1中带有'Active'Field4的所有内容。它不应包括'已取消'Field4。如果Table3有一个待定的Field2,它也应该不包括它。我很感激任何帮助。谢谢。

Well, you just need to join all the tables required to have the fields needed in the where clause.
好吧,你只需要加入where子句中所需字段所需的所有表。
And add a where
clause.
并添加一个where子句。
SELECT t2.Field3,
SUM(t1.Field2) as CTotal,
count(*) as NbItems
FROM Table1 t1
INNER JOIN Table2 t2
ON t1.Field3 = t2.Field1
--add a join on Table3
INNER JOIN Table3 t3
ON t3.Field1 = t1.Field5
--add your where clause
WHERE t1.Field4 = 'Active'
AND t3.Field2 <> 'Pending'
GROUP BY t2.Field3
--ORDER BY CTotal DESC
