Question

我理解如何将计数与group by一起使用，但是我需要特定使用这个反向，我尝试做这个查询：

SELECT
        COUNT(pac.strid_paciente)
    FROM tb_paciente AS pac
    LEFT JOIN tb_entidades AS ent
        ON pac.strid_entidad = ent.strid_entidad
    LEFT JOIN tb_escolaridad AS esc
        ON pac.strid_escolaridad = esc.strID_Escolaridad
    LEFT JOIN tb_etnia AS etn
        ON pac.strid_etnia = etn.strID_Etnia
    LEFT JOIN tb_raza AS raza
        ON pac.strid_raza = raza.strid_raza
    LEFT JOIN tb_religion AS rel
        ON pac.strid_religion = rel.strid_religion
    LEFT JOIN tb_ocupacion AS ocu
        ON pac.strOfi_Paciente = ocu.strID_Ocupacion
    LEFT JOIN tb_consulta AS con
        ON pac.strid_paciente = con.strid_paciente
    LEFT JOIN tb_usuarios AS usu
        ON usu.strid_usuario = con.strid_medico
    GROUP BY pac.strid_paciente

它给了我：

COUNT(pac.strid_paciente)
1
1
2
3
4
5
2

我需要每个计数的结果：18，问题是我不能删除组，因为给出不同的结果。这样的事情：

   COUNT(pac.strid_paciente)
   18

Answer 1

您是否尝试过pd.read_fwf("large_text_file.txt")或者如果失败，则以下内容将起作用：

SUM( COUNT(pac.strid_paciente) )

Mysql计数组通过反向
