摘要:SQL - Outer Apply
一值在這份工作之前，在撰寫SQL一值都沒有用的很深，Outer apply這種語法，我還從來沒使用過
但是用熟之後發現還挺好用的，因此寫個簡單的例子分享給大家。
Before change a new career. I just use simple SQL Script. So ~ I never been used
"outer apply". I found it's really convient after I get use to it. Here have a simple
sample to help people know how to use it.
【SAMPLE】
SELECT *
FROM (SELECT *
FROM (SELECT 'I' AS Suject,
'LOVE' AS Verb,
'U' AS Noun) A) TB1
OUTER apply (SELECT noun
FROM (SELECT 'Love' AS Verb,
'And MY FAMILY' AS Noun) B
WHERE B.verb = TB1.verb) TB2
【RESULT】
BTW. Here have a nice web page share with u guys. it can help u to format ur SQL Script.
