Sql server SQL Server中具有多个表的多个聚合函数

我正在尝试获取输入人员的数据，我希望提取特定人员的发票号和行项目号数据

输出是

Entered_by  No of line items
CD               9
CD               136084
deepa             7
deepa             18
dolly             757
dolly             22350
kroshni         666
kroshni         16161
lokesh           4
lokesh           999
MHeera           639
MHeera             20427
nandini            7
nandini            5318

这里，行项目数量中的数据是“行项目数量”计数和“发票数量”计数的混合，我想这样显示

Entered_by  No of line items    No of invoices
CD               136084              9
deepa               18                7
dolly               22350               757

请帮帮我这个人…。。

下面是T-SQL查询

select ENTERED_BY, count(entered_by) 'NO OF LINE ITEMS'
from im_invoice, im_invoice_line_item, im_invoice_inventory 
where invoice_rid = invoice_fk
and invoice_inventory_rid = invoice_inv_fk
and enter_date between dateadd(mm, -3, getdate()) and dateadd(mm,0,getdate())
group by entered_by

union 

select entered_by, count(invoice_num) 'NO OF INVOICES' from im_invoice
where enter_date between dateadd(mm, -3, getdate()) and dateadd(mm,0,getdate())
group by entered_by

正如Joe所说，如果你给我们一个更详细的描述，我们可以给你更好的答案，但在此之前，实现这一点的捷径如下：

摆脱工会

将这两个查询转换为派生表

根据输入的\ u从他们中进行选择

例如

你能澄清这三个表之间的关系吗？列

invoice\u rid

、

invoice\u fk

、

invoice\u invoint\u rid

和

invoice\u fk

属于哪些表？

SELECT LineItems.ENTERED_BY, [NO OF LINE ITEMS], [NO OF INVOICES] 
FROM
(SELECT ENTERED_BY,COUNT(entered_by) 'NO OF LINE ITEMS' 
FROM im_invoice, im_invoice_line_item,im_invoice_inventory   
WHERE invoice_rid = invoice_fk  
AND invoice_inventory_rid = invoice_inv_fk
AND enter_date BETWEEN dateadd(mm, -3, getdate()) AND dateadd(mm,0,getdate())
GROUP BY entered_by) AS LineItems 
INNER JOIN 
(SELECT entered_by, count(invoice_num) 'NO OF INVOICES' 
FROM im_invoice  
WHERE enter_date BETWEEN dateadd(mm, -3, getdate()) AND dateadd(mm,0,getdate())  
GROUP BY entered_by ) AS invoices 
ON invoices.entered_by = LineItems.ENTERED_BY
