我有一个关于在T-SQL中拆分列值的问题。 我有
Address_col
Nevada,USA
Tokyo,Japan
Hanoi,Vietnam
我想用逗号分隔值到
Address_col Country
Navada USA
Tokyo Japan
Hanoi Vietnam
我该怎么做?
答案 0 :(得分:5)
declare @T table (Address_col varchar(20))
insert into @T values
('Nevada,USA'),
('Tokyo,Japan'),
('Hanoi,Vietnam')
select left(Address_col, charindex(',', Address_col)-1) as Address_col,
stuff(Address_col, 1, charindex(',', Address_col), '') as Country
from @T

拆分三个部分的字符串可能如下所示:
声明@T表(Address_col varchar(20))
insert into @T values
('Nevada,USA,World'),
('Tokyo,Japan,World'),
('Hanoi,Vietnam,World')
select parsename(C, 3),
parsename(C, 2),
parsename(C, 1)
from @T
cross apply (select replace(Address_col, ',', '.')) as T(C)

如果你只有两个部分,那么这是我能想到的最简单的部分。
选择SUBSTRING(Address_col,1,CHARINDEX(',',Address_col)-1)作为Address_col, SUBSTRING(Address_col,CHARINDEX(',',Address_col)+ 1,LEN(Address_col))为国家
