你的子查詢是否自行返回任何東西？ – pancho018 2014-10-30 16:24:56

'points'後面需要逗號。你的子查詢只能返回*一個*行。我甚至不確定你可以在一個'INSERT'語句中使用子查詢。 – 2014-10-30 16:26:24

發佈示例時，最好使用產生錯誤的最簡單的示例。我猜你仍然會得到錯誤，如果你遺漏了第二條INSERT語句。 – cherdt 2014-10-30 16:31:17

要使用的構造是INSERT INTO ... SELECT ...。您不使用子查詢（或關鍵字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（以正確的順序）。

否分號在第一行的末尾。此外，INSERT語法可以清理一下。最後，GROUP BY子句不是必需的。試試這個：

試試這個：

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;

這是假定每個條目playerpoints記錄一個點。否則，您需要類似SELECT SUM(playerpoints.points）而不是SELECT COUNT(*)。
