PostgreSQL中具有相同名称（值）的列的总和

Question

我在PostgreSQL中使用以下查询：

SELECT
        pegawai_nama,
        COUNT(operasi_operator_dokter) AS total,
        CASE tindakan_golongan WHEN 'KECIL' THEN SUM(tariftindakan_biaya_alkes)
            ELSE 0
        END AS KECIL,
        CASE tindakan_golongan WHEN 'BESAR' THEN SUM(tariftindakan_biaya_alkes)
            ELSE 0
        END AS BESAR,
        CASE tindakan_golongan WHEN 'KHUSUS' THEN SUM(tariftindakan_biaya_alkes
            ELSE 0
        END AS SEDANG

    FROM
        t_operasi

    LEFT JOIN m_pasien On t_operasi.operasi_pasien_norm = m_pasien.pasien_norm
    LEFT JOIN t_pendaftaran on t_operasi.operasi_pendaftaran_id = t_pendaftaran.pendaftaran_id
    LEFT JOIN m_tindakan ON t_operasi.operasi_tindakan_id = m_tindakan.tindakan_id
    LEFT JOIN m_tarif_tindakan ON m_tindakan.tindakan_id = m_tarif_tindakan.m_tindakan_id
    LEFT JOIN m_pegawai ON cast(m_pegawai.pegawai_id as varchar(10)) = t_operasi.operasi_operator_dokter
    LEFT JOIN t_diagnosa_pasien ON t_diagnosa_pasien.t_pendaftaran_id = t_pendaftaran.pendaftaran_id
    LEFT JOIN m_icd ON m_icd.icd_id = t_diagnosa_pasien.m_icd_id

    WHERE operasi_id IS NOT NULL AND tindakan_golongan IN ('KECIL', 'BESAR', 'KHUSUS', 'SEDANG', '') 
    GROUP BY pegawai_nama, tindakan_golongan;

但是，下面的结果不是我想要的结果：

相反，我希望得到以下结果：

pegawai_nama            total    kecil     besar   sedang       khusus       
DR. JOKO TRIYONO, SPM   2        189000    0       909700       0                
DR. DJOHAR ANWAR        3        567000    0       0            0             

谢谢

Answer 1

尝试从GROUP BY中取出“tindakan_golongan”列。

Answer 2

将此作为嵌套查询，并再次对其进行分组：

select pegawai_nama, sum(total) as total , sum(kecil) as kecil, sum(besar) as besar, sum(sedang) as sedang
from (

-- insert your query here

) sub
group by pegawai_nama

感谢Georgi Raychev。你的代码非常非常帮助我。所以这是我的新代码

SELECT
        sub.pegawai_nama,
        sum(sub.total) as total,
        sum(sub.kecil) as kecil,
        sum(sub.besar) as besar,
        sum(sub.sedang) as sedang,
        sum(sub.khusus) as khusus

    FROM (

    SELECT
    pegawai_nama,
