Question

我必须在|之间选择，长度应该大于一。

DECLARE @c varchar(100)

set @c = 'Leslie|Nicole|McCrory'

SELECT SUBSTRING(STUFF(@c, 1, CHARINDEX('|',@c), ''), 0, CHARINDEX('|', STUFF(@c, 1, CHARINDEX('|',@c), '')))

结果：妮可

DECLARE @c varchar(100)

set @c = 'Leslie|N|McCrory'

SELECT SUBSTRING(STUFF(@c, 1, CHARINDEX('|',@c), ''), 0, CHARINDEX('|', STUFF(@c, 1, CHARINDEX('|',@c), '')))

结果：N

我需要的结果应该大于1。（即）Leslie | N | McCrory =＆gt;从这个N不应该被选中。

Answer 1

你的意思是：

DECLARE @c varchar(100)

set @c = 'Leslie|N|McCrory'

SELECT SUBSTRING(STUFF(@c, 1, CHARINDEX('|',@c), ''), 0, CHARINDEX('|', STUFF(@c, 1, CHARINDEX('|',@c), '')))
WHERE LEN(SUBSTRING(STUFF(@c, 1, CHARINDEX('|',@c), ''), 0, CHARINDEX('|', STUFF(@c, 1, CHARINDEX('|',@c), '')))) > 1

选择两个已知字符串之间的字符串并输出大于一的字符串
