INSERT，子查詢，價值

該查詢插入從othes表表中的值（它返回超過1行）INSERT，子查詢，價值

INSERT INTO metric_values(mv_db_id, mv_cat_id) 
    (SELECT DISTINCT dbs_id, cat_id FROM 
     (SELECT DISTINCT cat_id, dbs_id FROM categories 
      INNER JOIN users ON (cat_id = us_category_id) 
       INNER JOIN hits ON (us_id = h_user_id) 
       INNER JOIN dbs ON (h_db_id = dbs_id) 
      WHERE h_datetime = '2009-09-28' 
       GROUP BY cat_id, dbs_id)foo)

但我有一些變量（mv_metric_id，mv_period_id，mv_period_startdate），其值我收到來自程序（c＃）。任何人都知道如何在這個查詢中插入這個變量？

事情是這樣的：

INSERT INTO metric_values(mv_metric_id, mv_period_id, mv_period_startdate, mv_db_id, mv_cat_id) 
VALUES (1, 1, '2009-09-28', (SELECT DISTINCT dbs_id, cat_id 
           FROM (SELECT DISTINCT cat_id, dbs_id 
            FROM categories 
            INNER JOIN users ON (cat_id = us_category_id) 
            INNER JOIN hits ON (us_id = h_user_id) 
            INNER JOIN dbs ON (h_db_id = dbs_id) 
            WHERE h_datetime = '2009-09-28' 
            GROUP BY cat_id, dbs_id)foo))

請嘗試描述如何處理這些mv_metric_id，mv_period_id，mv_period_startdate變量。 – jarlh

像這樣'INSERT INTO metric_values（mv_metric_id，mv_period_id，mv_period_startdate，mv_db_id，mv_cat_id） VALUES（1，1， '2009-09-28'，（SELECT DISTINCT dbs_id，CAT_ID FROM （SELECT DISTINCT CAT_ID，dbs_id FROM類別 INNER JOIN用戶ON（CAT_ID = us_category_id） INNER JOIN命中ON（us_id = h_user_id） INNER JOIN DBS ON（h_db_id = dbs_id） WHERE h_datetime = '2009-09-28' GROUP BY CAT_ID，dbs_id）FOO ））' – Svetlana

你可以把自己的價值觀的最SELECT子句中，例如：

INSERT INTO metric_values(mv_metric_id, mv_period_id, mv_period_startdate, mv_db_id, mv_cat_id) 
    (SELECT DISTINCT MYDATA1, MYDATA2, MYDATA3, dbs_id, cat_id FROM 
     (SELECT DISTINCT cat_id, dbs_id FROM categories 
      INNER JOIN users ON (cat_id = us_category_id) 
       INNER JOIN hits ON (us_id = h_user_id) 
       INNER JOIN dbs ON (h_db_id = dbs_id) 
      WHERE h_datetime = '2009-09-28' 
       GROUP BY cat_id, dbs_id)foo)

當然，這將使整個行DISTINCT所以可能有重新組合你的SELECT條款。
