Add an alias after your last bracket.
在最后一个括号后添加别名。
select count(*) from
(select idCover from x90..dimCover group by idCover having count(*) > 1) a
回答by Frederik Gheysels
SELECT COUNT (*) FROM
( SELECT IdCover FROM x90..dimCover group by idCover having count(*) > 1) AS a
(note the alias at the end)
（注意最后的别名）
