SQL CAST或转换为SUM

Question

我有一个名为T5VAULTSL3的表，其中我的客户在标题VL3CLIENTNUM下，而其现金金额在VL3CONSIDERATION下；

VL3CONSIDERATION显示对象资源管理器为(char(20), null)

我想要实现的是将所有现金(consideration) is > 10000所有'Unique'客户编号分组

我努力了;

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

哪个返回

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

所以我尝试了

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

哪个返回

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

和

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

哪个返回

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

我需要使用“声明”功能吗？ 有点为此难过...

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.

绝对困惑！

我猜想原因是'0.00'里面有空格。 您最好修剪空间：

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