推荐答案

SQL具有CHARINDEX函数，所以我要做的是使用SUBSTRING来获取冒号和点之间的部分:

SQL has the CHARINDEX function, so what I would do is use SUBSTRING to fetch the part between the colon and the dot:

DECLARE @STR NVARCHAR(MAX)
SET @STR = 'Draw DATE 2014-05-23, UNIQUE number: B935036. Win 1 of 3 R100 000 holidays WITH Flight Center. Watch sky tv ON draw DATE AT 18h25. T''s and C''s '
SELECT SUBSTRING(@STR, CHARINDEX(':', @STR) + 2, 7)
