我收到此错误

将数据类型varchar转换为数字时出错。

这是我的代码：

Msg 8114，Level 16，State 5，Line 13 将数据类型varchar转换为数字时出错。

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,

有人帮助解决此错误

Answer 1

逐一检查以下内容：

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varchar

的decimal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'0'。

中使用'0cpn'作为字符串，而不是整数

所以它应该是

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

pn'') THEN

显示将varchar的错误转换为数字
