sql - 将货币符号附加到 sql 查询的结果

Question

sql查询的结果

select PayerDate,PaymentAmount from Payments

付款金额 - 小数

Date        Amount
12/11/2012  34.31
12/11/2012  95.60
12/11/2012  34.31

是否有可能得到如下查询结果：

Date        Amount
12/11/2012  $34.31
12/11/2012  $95.60
12/11/2012  $34.31

我已经尝试过，但找不到太多关于此的信息。

您可以将其连接到您的投影语句中，

在 MySQL 中，

SELECT PayerDate, CONCAT('$', PaymentAmount) PaymentAmount FROM Payments

在 SQL Server 中，

SELECT PayerDate, '$' + CAST(PaymentAmount AS VARCHAR(15)) PaymentAmount
FROM   Payments

试试这个查询

select PayerDate,'$'+convert(varchar,PaymentAmount) as PaymentAmount
from Payments

您可以转换PaymentAmount为字符串，并在其前面加上美元：

select  PayerDate
,       '$' + cast(PaymentAmount as varchar(20)) as PaymentAmount
from    Payments

John Woo sql server 的答案是正确的，但您可能会收到类似“"$" is not a valid column name”的错误。为防止此错误，请通过添加括号进行一些外壳保存。

SELECT PayerDate, ('$' + CAST(PaymentAmount AS VARCHAR(15))) AS PaymentAmount
FROM   Payments

注意：我只添加了括号。

可以尝试以下方法：

SELECT 
FORMAT([PayerDate], 'C' 'en-us') AS PayerDate ,
FORMAT([PaymentAmount], 'C', 'en-us') AS 'PaymentAmount' 
FROM Payments
