Question

I recently added a sorting field and now I want to sort the result. I could do it in PHP or directly on the database. So I tried the second one:

SELECT *
FROM constructions
AS whole
INNER JOIN
(
    SELECT DISTINCT construction
    FROM data
    AS results
    WHERE product =2
    AND application =1
    AND requirement =1
)
ON whole.id = results
ORDER BY whole.sorting

I tried to use inner join to match the complete table with the result set. But I can’t get it working (#1248 - Every derived table must have its own alias). I tried to use the alias but something is still wrong. Perhaps I shouldn’t user inner join and use IN() instead.

Answer 1

2 obvious errors in the syntax:

SELECT *
FROM constructions
AS whole
INNER JOIN
(
    SELECT DISTINCT construction AS results
    FROM data
    WHERE product =2
    AND application =1
    AND requirement =1
) AS a
ON whole.id = a.results
ORDER BY whole.sorting
