sql语句提示"LEFT": syntax error！大家帮忙看看
SELECT PROJ.PROJECTID, COUNT(*) AS COUNT ,D.NUMBER AS NUMBER FROM PROJECTEQUIPMENT_V1 PROJ GROUP BY PROJECTID
LEFT JOIN(SELECT PROJE.PROJECTID, COUNT(*) AS NUMBER FROM PROJECTEMPLOYEE_V1 PROJE GROUP BY PROJECTID) D
ON PROJ.PROJECTID=D.PROJECTID

[Err] 1 - near "LEFT": syntax error
哪位大侠帮看看，是哪出了问题，谢谢！！！

要么把第一个Group By去掉，如果要用Group By的话可以做成Subquery跟下面的一样，这样就不会错了。

--楼主写的语法不对。参考如下：

SELECT 
a.PROJECTID,A.[COUNT],D.[NUMBER]
FROM
(
SELECT 
PROJ.PROJECTID, 
COUNT(*) AS COUNT
FROM PROJECTEQUIPMENT_V1 PROJ 
GROUP BY PROJECTID
) A
LEFT JOIN
(
SELECT PROJE.PROJECTID, COUNT(*) AS NUMBER 
FROM PROJECTEMPLOYEE_V1 PROJE 
GROUP BY PROJECTID
) D
ON A.PROJECTID=D.PROJECTID
