Answer 1

添加查询

SELECT   numero_documento,COUNT(*) AS cuantos
FROM dbo.PERSONAL GROUP BY numero_documento 
having count(numero_documento) > 1
order by cuantos desc 

Answer 2

有时看到另一种做某事的方法会很有帮助。我并没有声称这样做会更好，但它确实有效。

使用像这样的子查询

Select * from
(
  SELECT   numero_documento,COUNT(*) AS cuantos
  FROM dbo.PERSONAL 
  GROUP BY numero_documento 
) G1
WHERE cuantos > 1
order by cuantos desc
