Substring SQL 服务器中带有 charindex 的字符串中的一个单词

Question

I am trying to write a query to extract a word from a string. For example, I want to get the word Final from the sentence: this is the final exam .

I want only to get the word 'final' using charindex to determine the start and end of the substring function.

I think this is what you are asking for. Please have a look at this:

Declare @start INT;
Declare @end int;

set @start=CHARINDEX('Fi','this is the final exam');
set @end =CHARINDEX('al','this is the final exam');
if(@start >0 and @end>0)
Begin
SELECT
       SUBSTRING('this is the final exam', 
                  @start, 
                  5)
END
