关于减少PHP查询

Question

我正在尝试以下查询，它可以正常工作，但是有什么方法可以减少它？

<?php
$c_qr="
    SELECT count(profit) AS 'y_c'
        ,profit AS 'x_c'
    FROM account
    WHERE profit = 'excellent'

    UNION

    SELECT count(profit) AS 'c1'
        ,profit AS 'c2'
    FROM account
    WHERE profit = 'fair'

    UNION

    SELECT count(profit) AS 'c1'
        ,profit AS 'c2'
    FROM account
    WHERE profit = 'bad'

    UNION

    SELECT count(sale) AS 'c1'
        ,sale AS 'c2'
    FROM account
    WHERE sale = 'excellent'

    UNION

    SELECT count(sale) AS 'c1'
        ,sale AS 'c2'
    FROM account
    WHERE sale = 'fair'

    UNION

    SELECT count(sale) AS 'c1'
        ,sale AS 'c2'
    FROM account
    WHERE sale = 'bad'

    UNION

    SELECT count(purchase) AS 'c1'
        ,purchase AS 'c2'
    FROM account
    WHERE purchase = 'excellent'

    UNION

    SELECT count(purchase) AS 'c1'
        ,purchase AS 'c2'
    FROM account
    WHERE purchase = 'fair'

    UNION

    SELECT count(purchase) AS 'c1'
        ,sale AS 'c2'
    FROM account
    WHERE purchase = 'bad'
";
