sqlserver2012 將字符串分割
例如 字符串‘1,2,3,4,5’ 爲了達到如下效果：
函數如下：
SELECT Split.a.value('.', 'NVARCHAR(MAX)') DATA
FROM(
SELECT CAST('<X>'+REPLACE('1,2,3,4,5', ',', '</X><X>')+'</X>' AS XML) AS String
) AS A CROSS APPLY String.nodes('/X') AS Split(a)
配合 in使用：
select id,title,ctime from table where '12' in (
SELECT Split.a.value('.', 'NVARCHAR(MAX)') DATA
FROM(
SELECT CAST('<X>'+REPLACE(title, ',', '</X><X>')+'</X>' AS XML) AS String
) AS A CROSS APPLY String.nodes('/X') AS Split(a)
)
