簡單的SQL聯盟2個查詢在同一個表

Question

試圖讓所有行其中userid = '我'

然後2名最新行其中userid <> '我'

項目：

 
Userid time 
other2 11 
other3 10 
me  10 
me  8 
other1 8 
other3 7 
me  6 

將返回

 
Userid time 
me  10 
me   8 
me   6 
other2 11 
other3 10 

結果不必爲b E在任何順序

(SELECT * FROM Items WHERE userid='me') 
UNION ALL 
(SELECT * FROM Items WHERE userid<>'me' 
ORDER BY time DESC LIMIT 2) 

這僅輸出2行

Answer 1

如上所示

(SELECT * FROM Items WHERE userid='me') 
UNION ALL 
(SELECT * FROM Items WHERE userid<>'me' 
ORDER BY time DESC LIMIT 2) 

UNION ALL地連接了兩個查詢，並且括號允許不同WHERE /訂購SQL是正確的BY/LIMIT子句。
