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

PaymentAmount - 十进制

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

可以获得如下查询结果：

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

我已经尝试了但是找不到太多关于此的信息。

Answer 1

您可以在投影声明中将其连接起来，

<击>

<击>

在MySQL中，

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

<击>

在SQL Server中，

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

Answer 2

尝试此查询

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

Answer 3

您可以将PaymentAmount转换为字符串，并以美元为前缀：

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

Answer 4

John Woo sql服务器答案是正确的，但是您可能会收到诸如““ $”不是有效的列名“之类的错误。为了防止出现此错误，请在括号中加上一些括号。

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

注意：我只添加了括号。

Answer 5

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
