I am attempting to get the last word from table Project in SQL-Server 2017.

My code is as follows:

select 
reverse(substring(reverse(ProjectDescription),1, charindex(' ', reverse(ProjectDescription)) -1)) as LastWord
from Project 

The code works if I ask isolate the table to a single line, but I need the last word for all lines in the field ProjectDescription.

当我运行上述代码时，出现以下错误：

传递给 LEFT 或 SUBSTRING 函数的长度参数无效。

请有人帮助我解决我哪里出错了。

我正在尝试创建一个新视图,但我也希望此视图有一个新列.新列必须是StkCode和Description_1的组合.

例如:如果我的StkCode是DX11122而Description_1是香草粉; 我想要一个字段如下:"香草粉 - DX11122"

CREATE VIEW KFF_Rep_Comm
AS
SELECT vw_KLX_RepCommTrx.AccName AS AccountName
,vw_KLX_RepCommTrx.Account AS AccountNum
