SQL强制转换或转换为SUM

我有一个名为

T5VAULTSL3

的表，其中我的客户在

VL3CLIENTNUM

列标题下，他们的现金金额在

VL3CONSIDERATION

下

VL3CONSIDERATION

将对象浏览器显示为

（char（20），null）

我试图实现的是将所有的

“唯一的”

客户编号分组，其中合并的现金

（对价）大于10000

我试过了

SELECT vl3clientnum, CAST(VL3CONSIDERATION AS NUMERIC (20,2))
FROM T5VAULTSL3
WHERE Vl3CONSIDERATION > 10000

返回

Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value ' 0.00' to data type int.

Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

所以我试过了

SELECT vl3clientnum, VL3CONSIDERATION
FROM T5VAULTSL3
WHERE CAST (Vl3CONSIDERATION AS NUMERIC (20,2)) > 10000

返回

Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value ' 0.00' to data type int.

Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

及

返回

Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value ' 0.00' to data type int.

Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

我是否需要使用“声明”功能？如果需要，如何使用？有点被这件事难住了

其他尝试包括

SELECT vl3clientnum, CAST (VL3CONSIDERATION AS NUMERIC (20,2))
FROM T5VAULTSL3
WHERE VL3CONSIDERATION > 10000
GROUP BY VL3CLIENTNUM, vl3consideration

Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value ' 0.00' to data type int.


SELECT vl3clientnum, VL3CONSIDERATION
FROM T5VAULTSL3
WHERE CAST (VL3CONSIDERATION as NUMERIC(20,2)) > 10000
GROUP BY VL3CLIENTNUM, vl3consideration

Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.

非常困惑

我想原因是“0.00”中有一个空格。您最好修剪空间：

CAST(LTRIM(RTRIM(VL3CONSIDERATION)) AS NUMERIC (20,2))
