使用一个查询为第二个查询设置范围

Question

早上好

我有以下问题。有效我正在尝试使用第一个查询生成的客户端列表传递给第二个查询以提取我需要提取的交易列表。

我是 sql 的新手，所以不确定是否可行。谁能建议一个解决方案

--create list of client_accs 

select client_id, client_acc
from client_crm
where client_id = 'LOG0000240'

--select transaction data for list of client generated in first query

Select 
client_id,
test_cash_trans.client_acc,
sub_trans_type,
settle_date,
dbt_crt,
test_cash_trans.currency,
cash_amount,
test_cash_trans.last_update
From test_cash_trans

inner join client_crm
on test_cash_trans.client_acc = client_crm.client_acc

where test_cash_trans.client_acc in --- result of first query

group by client_id,test_cash_trans.client_acc, sub_trans_type, settle_date, dbt_crt, test_cash_trans.currency, cash_amount,test_cash_trans.last_update

Answer 1

您可能正在寻找 IN:

test_expression [ NOT ] IN   
    ( subquery | expression [ ,...n ]  
    )

Determines whether a specified value matches any value in a subquery or a list.

这是一个例子：

SELECT p.FirstName, p.LastName  
FROM Person.Person AS p  
    JOIN Sales.SalesPerson AS sp  
    ON p.BusinessEntityID = sp.BusinessEntityID  
WHERE p.BusinessEntityID IN  
   (SELECT BusinessEntityID  
   FROM Sales.SalesPerson  
   WHERE SalesQuota > 250000);
