Mysql查詢的對應Sqlite查詢語法

Question

請幫我找到下面查詢的sqlite等價物。嘗試了很多。

SET @rownum := 0; 
SELECT * FROM (
SELECT @rownum := @rownum+1 AS rank, id 
FROM tbl_flight 
ORDER BY id DESC 
) AS tbl_flight WHERE id = 2 

Answer 1

不能在單個查詢做到這一點，但您可以使用臨時表和每個表的ROWID屬性：

http://sqlfiddle.com/#!5/f0a1b/8（您不能運行小提琴兩次，你必須始終重新運行前先重建模式）

DROP TABLE IF EXISTS tmp; 

CREATE TEMPORARY TABLE tmp AS 
    SELECT id 
    FROM tbl_flight 
    ORDER BY id DESC; 

SELECT tmp.rowid AS rank, tmp.id FROM tmp WHERE id=2;
