我创建了一个查询来删除表中的重复行.我试图这样做,但输出是"太多的价值"

DELETE FROM Employeetest 
WHERE employeeid IN (SELECT 
                         employeetest.*, 
                         ROW_NUMBER() OVER (PARTITION BY employeeid ORDER BY employeeid) AS rownumber 
                     FROM
                         employeetest 
                     HAVING
                         (rownumber > 1)); 

我也做了

SELECT
    employeetest.*, 
    ROW_NUMBER() OVER (PARTITION BY employeeid ORDER BY employeeid) AS rownumber 
FROM
    employeetest

然后

DELETE * FROM employeetest;

它不起作用
