Question

运行多个选择查询并将数据输出到相同的xml值中最合适的方法是什么？

SELECT 
    count(empID) as totalOrders 
FROM 
    chandlerBrandLaunch 
WHERE 
    orderStatus = 'Complete'
FOR XML PATH ('data'), TYPE, ELEMENTS, ROOT ('results');

SELECT 
   count(empID) as totalPayments 
FROM 
   chandlerBrandLaunch 
WHERE 
   paymentStatus = 'Complete'
FOR XML PATH ('data'), TYPE, ELEMENTS, ROOT ('results');

我的陈述是获得不同的数据计数以及WHERE子句的不同。

我只是希望能够为多个项目提取统计数据，并将其全部包含在一个输出中。

如果有帮助，您可以在一个选择中同时选择：

SELECT 
    sum(case when empid is not null and orderStatus = 'Complete' then 1 else 0 end as totalOrders,
    sum(case when empid is not null and paymentStatus = 'Complete' then 1 else 0 end as totalPayments
FROM 
    chandlerBrandLaunch

TSQL多个选择Stats
