Question

Using the MySQL code below along with ORDER BY is not working. I've searched and tried various version of the code (UNION, UNION ALL, with brackets, without brackets, a SELECT wrapping all the SELECT UNION ALLs then sorting that) - no luck. Any other suggestions?

        (SELECT FORMAT(lt.`rets_111`, 0) AS 'ListPrice', lt.`rets_128` AS 'MlsNumber', lt.`rets_13` AS 'Address', lt.`rets_2044` AS 'PublicRemarks', lt.`rets_sysid`, @real_estate_type:='res' AS real_estate_type,
    lt.`rets_2362` AS 'OpenHouseDate1', lt.`rets_2364` AS 'OpenHouseStartTime1', lt.`rets_2366` AS 'OpenHouseEndTime1', lt.`rets_2370` AS 'DisplayOpenHouse1',
    lt.`rets_2372` AS 'OpenHouseDate2', lt.`rets_2374` AS 'OpenHouseStartTime2', lt.`rets_2376` AS 'OpenHouseEndTime2', lt.`rets_2380` AS 'DisplayOpenHouse2'
    FROM res_listings AS lt
    WHERE lt.`rets_32` IN ('AGENT1', 'AGENT2') OR lt.`rets_2337` IN ('AGENT1', 'AGENT2') OR lt.`rets_1836` IN ('AGENT1', 'AGENT2'))

    UNION ALL

    ORDER BY 'ListPrice' DESC
Was it helpful?

Solution

This is your order by:

ORDER BY 'ListPrice' DESC

It is ordering by a constant string. Try this:

ORDER BY ListPrice DESC

And, in the future, only use single quotes for string and date constant values. Never, ever for the names of things in the database.
