example: SELECT title,ROW_NUM FROM article ORDER BY count_read. What should ROW_NUM be replace by ?
I don't like to after getting the results generate the index by program, because I want to insert into a table Rank with the result data by querying the example DQL above.
What I want to achieve maybe like :
"INSERT INTO RANK r (title, index, lastIndex)
SELECT title,ROW_NUM,(SELECT index FROM RANK WHERE id = :id - 1) FROM article ORDER BY count_read"
Thanks in advance..
I think you might use variables, like this:
"
SET @row_num := 1;
INSERT INTO RANK r (title, index, lastIndex)
SELECT title,
(@row_num := @row_num + 1),
(SELECT index FROM RANK WHERE id = :id - 1)
FROM article ORDER BY count_read
"
