Question

我试图从使用2个表和group by ...的select语句构建的表数据中提取，然后将每行数据输出为一行连接文本。

我已经尝试尝试进行DECLARE，SET和打印为concat字符串。

use ap;

SELECT v.vendorid as 'VendorID', count(i.invoiceid) as 'Invoice Count', 
sum(i.invoicetotal) as 'Invoice Total' 
FROM vendors v
JOIN invoices i on i.vendorid = v.vendorid
GROUP BY v.vendorid

试图将其输出为...

供应商ID = 34发票计数2发票总数= 1,200.12

只需将其连接为字符串即可。您只需要将数字值转换为VARCHAR。

select 'VendorID = ' + CAST(v.vendorid AS VARCHAR(10)) + ' Count ' + CAST(count(i.invoiceid) AS VARCHAR(10)) +
    ' Invoice Totals = ' + FORMAT(sum(i.invoicetotal), 'c2')
from vendors v JOIN invoices i on i.vendorid = v.vendorid 
group by v.vendorid

使用此示例数据：

create table vendors (vendorid int)
create table invoices (vendorid int, invoiceid int, invoicetotal money)

insert into vendors values (34)
insert into invoices values (34, 1, 1000), (34, 2, 200.12)

返回：

VendorID = 34 Count 2 Invoice Totals = $1,200.12

我如何将表数据（多行）输出为多行连接的字符串
