你的子查询是否自行返回任何东西？ – pancho018 2014-10-30 16:24:56

'points'后面需要逗号。你的子查询只能返回*一个*行。我甚至不确定你可以在一个'INSERT'语句中使用子查询。 – 2014-10-30 16:26:24

发布示例时，最好使用产生错误的最简单的示例。我猜你仍然会得到错误，如果你遗漏了第二条INSERT语句。 – cherdt 2014-10-30 16:31:17

要使用的构造是INSERT INTO ... SELECT ...。您不使用子查询（或关键字VALUES）。

INSERT INTO TempTable (myid, points) 
SELECT player.team, COUNT(*) AS count 
FROM playerpoints 
JOIN player ON playerpoints.PlayerID = player.PlayerID 
WHERE player.team = 'ManU' 
AND EXTRACT(MONTH FROM playerpoints.date) <07 
GROUP BY player.team;

基本上，你想要的SELECT返回行（）你要插入（以正确的顺序）。

否分号在第一行的末尾。此外，INSERT语法可以清理一下。最后，GROUP BY子句不是必需的。试试这个：

试试这个：

CREATE TEMPORARY TABLE TempTable(myid INT,points INT); 

INSERT INTO TempTable 
values(1, (
    SELECT COUNT(*) 
    FROM playerpoints 
    JOIN player ON playerpoints.PlayerID = player.PlayerID 
    WHERE player.team = 'ManU' 
    AND EXTRACT(MONTH FROM playerpoints.date) <07 
)); 

INSERT INTO TempTable 
values(2, (
    SELECT COUNT(*) 
    FROM playerpoints 
    JOIN player ON playerpoints.PlayerID = player.PlayerID 
    WHERE player.team = 'ManU' 
    AND EXTRACT(MONTH FROM playerpoints.date) >07 
)); 

... 

DROP TABLE TempTable;

这是假定每个条目playerpoints记录一个点。否则，您需要类似SELECT SUM(playerpoints.points）而不是SELECT COUNT(*)。
