對查詢結(jié)果進行行轉(zhuǎn)列操作要用到的SQL語句
在使用SQL數(shù)據(jù)庫的時候，進行查詢后，如何對查詢結(jié)果進行行轉(zhuǎn)列操作呢？下面就將為您介紹執(zhí)行該操作要用到的SQL語句，供您參考，希望對您學(xué)習(xí)SQL語句有所幫助。
測試數(shù)據(jù)：
code price
'MCU0-3' 15
'MCU0-3' 20
'MCU0-3' 22
'MCU3-15' 17
'MCU3-15' 16
'MCU3-15' -10
'MCU3-15' 50
'MCU3-27' 99
'MCU3-27' 96
'MCU3-27' 54
'MCU3-27' 14
'MCU3-27' 46
'MCU3-27' 86
結(jié)果：
MCU0-3 MCU3-15 MCU3-27
15 17 99
20 16 96
22 -10 54
null 50 14
null null 46
null null 86
