将数据类型 varchar 转换为数值时出错。

这是我的代码：

我可以发现这是一个错误

 CAST(  CASE WHEN CAST(REPLACE(ISNULL(DI.PX2,0),'%','') AS DECIMAL(18,5)) = 0.00 THEN (CASE WHEN ISNULL(CAST(DI.Yield * 100 AS DECIMAL(18,3)),0) = 0 THEN (CASE WHEN (ISNULL(DI.Coupon,0)+'cpn' = 'cpn' OR ISNULL(DI.Coupon,0)+'cpn' = '0cpn') THEN '-' ELSE (ISNULL(DI.Coupon,0)+'cpn')END)ELSE CAST(ISNULL(CAST(DI.Yield * 100 AS DECIMAL(18,3)),0) AS VARCHAR(15))+'%yld' END) ELSE (ISNULL(DI.PX,0)) END AS VARCHAR(20)) AS 'Spread',  CAST(  ISNULL(CAST(DI.Yield * 100 AS DECIMAL(18,3)),0) AS VARCHAR(20)) AS 'Yield', CAST(  CASE WHEN LTRIM(RTRIM(DI.Dollar_Px)) = '' THEN 0.00 ELSE CAST(ISNULL(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(LTRIM(RTRIM(Dollar_Px)),CHAR(10),''),CHAR(13),''),'-',''),'/',''),' ',''),'%cpn',''),0) AS DECIMAL(18,5)) END AS VARCHAR(20)) AS 'Dollar_Px',  ISNULL(Notes,'') AS Notes,

有人帮助解决这个错误

Answer 1

下面一一检查：

SELECT ISNUMERIC(ISNULL(DI.PX2,0)) FROM DI WHERE ISNUMERIC(ISNULL(DI.PX2,0)) = 0

SELECT ISNUMERIC(ISNULL(DI.Yield,0)) FROM DI WHERE ISNUMERIC(ISNULL(DI.Yield,0)) = 0

SELECT ISNUMERIC(ISNULL(Dollar_Px,0)) FROM TABLE WHERE ISNUMERIC(ISNULL(Dollar_Px,0)) = 0

必须存在任何无法转换为decimal的varchar字符串

Answer 2

这是一个错误：

(ISNULL(DI.Coupon,0)+''cpn'' = ''cpn'' OR ISNULL(DI.Coupon,0)+''cpn'' = ''0c

pn'') THEN

您的优惠券是 varchar，但如果是 NULL，则使用 0 代替它。 您应该在您的'0cpn' 中使用'0'，因为它是字符串，而不是整数。

应该是这样的

(ISNULL(DI.Coupon,''0'')+''cpn'' = ''cpn'' OR ISNULL(DI.Coupon,''0'')+''cpn'' = ''0c

pn'') THEN
