Question

我希望MonthlyPayment有列float PaymentAmount 数字（18,3）

我在PaymentAmount中有这样的数据：

PaymentAmount
--------------
1230.25
829122.35

我想像这样返回付款金额：

PaymentAmount
--------------
000000001230.25
000000829122.35

我使用了这个查询，但它返回：

PaymentAmount
--------------
000000000001230
000000000829122

查询：

SELECT ISNULL(replace(str(MonthlyPayment.PaymentAmount,15,0),' ','0'),SPACE(15)) 
FROM MonthlyPayment

Answer 1

对于SQL Server 2012 +，您可以使用FORMAT

SELECT FORMAT(PaymentAmount, '00000000000#.##')
FROM MonthlyPayment

示例执行：

DECLARE @PaymentAmount AS DECIMAL (18,2) = 1230.25;
SELECT FORMAT(@PaymentAmount,'00000000000#.##');
-- OUTPUT: 000000001230.25

DECLARE @PaymentAmount1 AS DECIMAL (18,2) = 829122.35;
SELECT FORMAT(@PaymentAmount1,'00000000000#.##');
-- OUTPUT: 000000829122.35

Answer 2

如果您的SQL Server版本有REPLICATE可用，那么您可以使用所需的零数小心地填充PaymentAmount列，以使总字符串的宽度为15个字符。

SELECT REPLICATE('0',
                 15 - LEN(CONVERT(VARCHAR, CONVERT(DECIMAL(14, 2), PaymentAmount))))
     + CONVERT(VARCHAR, CONVERT(DECIMAL(14, 2), PaymentAmount))
FROM MonthlyPayment

Answer 3

这适用于任何版本的SQL Server

SELECT RIGHT('000000000000' + CAST(CAST(PaymentAmount AS NUMERIC(18,2)) AS VARCHAR(20)),15)
FROM MonthlyPayment

Eample:

DECLARE @PaymentAmount AS DECIMAL (18,3) = 1230.256;
SELECT RIGHT('000000000000' + CAST(CAST(@PaymentAmount AS NUMERIC(18,2)) AS VARCHAR(20)),15)

DECLARE @PaymentAmount1 AS DECIMAL (18,3) = 829122.35;
SELECT RIGHT('000000000000' + CAST(CAST(@PaymentAmount1 AS NUMERIC(18,2)) AS VARCHAR(20)),15)

如何替换零并输入十进制数？
