INSERT，子查询，价值

该查询插入从othes表表中的值（它返回超过1行）INSERT，子查询，价值

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)

但我有一些变量（mv_metric_id，mv_period_id，mv_period_startdate），其值我收到来自程序（c＃）。任何人都知道如何在这个查询中插入这个变量？

事情是这样的：

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))

请尝试描述如何处理这些mv_metric_id，mv_period_id，mv_period_startdate变量。 – jarlh

像这样'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类别 INNER JOIN用户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

你可以把自己的价值观的最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)

当然，这将使整个行DISTINCT所以可能有重新组合你的SELECT条款。
