Question

我有一个名为T5VAULTSL3的表格，我的客户位于VL3CLIENTNUM列标题下，其现金金额低于VL3CONSIDERATION;

VL3CONSIDERATION将对象资源管理器显示为(char(20), null)

我想要实现的是将所有'Unique'个客户编号分组，其中合并现金(consideration) is > 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.

所以我试过

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

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

返回

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

我是否必须使用'声明'功能，如果是，如何使用？有点难过这个......

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!!!!

Answer 1

我猜原因是'0.00'中有空格。你最好修剪空间：

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

SQL CAST或转换为SUM
