我对将2个查询变成1个查询感到困惑，因为这些查询对我来说太复杂了。这是我的第一个疑问。

SELECT
    COALESCE(s1.kode_barang, s2.kode_barang) AS kode_barang,
    COALESCE(s1.nama, s2.nama) AS nama,
    COALESCE(s1.sisa, 0) AS sisa_JUNI,
    COALESCE(s2.total_jumlah, 0) AS masuk_JULI,
    COALESCE(s1.sisa, 0) + COALESCE(s2.total_jumlah, 0) AS total

    GROUP BY
        sb.nama
) s2 ON s1.nama = s2.nama
WHERE
    s1.nama IS NULL
ORDER BY
    nama;

这是我的第二个疑问。

SELECT COALESCE(sm.kode_barang, s1.id) AS kode_barang, 
COALESCE(sb.nama, s1.nama) AS nama, 
SUM(sm.jumlah) AS keluar_JULI, 
s2.sisa AS sisa_JULI
FROM ws_fh.simas_mutasi sm
LEFT JOIN ws_fh.simas_barang sb ON sb.id = sm.kode_barang
LEFT JOIN (
    SELECT sm1.kode_barang, sm1.tanggal AS max_tanggal, sm1.created_at, sm1.sisa
    FROM ws_fh.simas_mutasi sm1
    JOIN (
        SELECT kode_barang, MAX(tanggal) AS max_tanggal, created_at
        FROM ws_fh.simas_mutasi
        WHERE tanggal BETWEEN '2022-07-01' AND '2022-07-31'
        GROUP BY kode_barang
    ) sm2 ON sm2.kode_barang = sm1.kode_barang AND sm2.max_tanggal = sm1.tanggal
    GROUP BY sm1.kode_barang, sm1.created_at, sm1.sisa
    ORDER BY sm1.kode_barang, sm1.created_at DESC
) s2 ON s2.kode_barang = sb.id
RIGHT JOIN ws_fh.simas_barang s1 ON s1.id = s2.kode_barang
WHERE COALESCE(sb.jenis, s1.jenis) = 'ATK DAN SEJENISNYA'
GROUP BY COALESCE(sb.nama, s1.nama)
HAVING keluar_JULI IS NOT NULL AND sisa_JULI IS NOT NULL
ORDER BY COALESCE(sb.nama, s1.nama);

我想把所有这些都变成一个查询。对“nama”使用group by，这样第一个查询和第二个查询中的相同“nama”将位于同一行中。如果第一个查询中的“nama”与第二个查询中的“nama”不匹配，则将其显示在表中。

为此，您需要一个完整的外部连接，MySQL不支持，MySQL 8至少在某种程度上更具可读性
