插入重复密钥更新时出现“无法使用组功能”更新

Question

我在查询时遇到了问题，我想在重复时插入和更新，但它表示“无效的组功能使用”。

我运行了我唯一的“选择”语句，没有像“无效的组功能使用”这样的问题。

这里是我的全码：

INSERT INTO tbl_biir_aktual(cabang_kode, periode_thn, periode_bln, pending_pp_volume, pending_pp_value) 
SELECT a.cabang_kode, YEAR(a.tanggal) AS tahun, MONTH(a.tanggal)AS bulan, 
    SUM(a.qty_pending*a.unit_barang)AS tonase_pending, SUM(a.value_pending)AS value_pending 
FROM tbl_order a, 
    (SELECT b.cabang_kode, MAX(b.tanggal)tanggal 
    FROM tbl_order b 
    GROUP BY b.cabang_kode, YEAR(b.tanggal), MONTH(b.tanggal)) AS max_cabang 
WHERE max_cabang.cabang_kode = a.cabang_kode AND max_cabang.tanggal = a.tanggal 
GROUP BY cabang_kode, YEAR(tanggal), MONTH(tanggal) 
ON DUPLICATE KEY 
UPDATE pending_pp_volume = SUM(a.qty_pending*a.unit_barang), pending_pp_value = SUM(a.value_pending); 

好， 嘿，我刚刚发现这个MySQL ON DUPLICATE KEY UPDATE while inserting a result set from a query

INSERT INTO tbl_biir_aktual(cabang_kode, periode_thn, periode_bln, pending_pp_volume, pending_pp_value) 
SELECT a.cabang_kode, YEAR(a.tanggal) AS tahun, MONTH(a.tanggal)AS bulan, 
    @tonase_pending := SUM(a.qty_pending*a.unit_barang)AS tonase_pending, @value_pending := SUM(a.value_pending)AS value_pending 
FROM tbl_order a, 
    (SELECT b.cabang_kode, MAX(b.tanggal)tanggal 
    FROM tbl_order b 
    GROUP BY b.cabang_kode, YEAR(b.tanggal), MONTH(b.tanggal)) AS max_cabang 
WHERE max_cabang.cabang_kode = a.cabang_kode AND max_cabang.tanggal = a.tanggal 
GROUP BY cabang_kode, YEAR(tanggal), MONTH(tanggal) 
ON DUPLICATE KEY 
UPDATE pending_pp_volume = @tonase_pending, pending_pp_value = @value_pending; 

我已经试过了，它的完成。 Tq的Edper的评论反正....

尝试使用别名在您的更新：

UPDATE SET pending_pp_volume = tonase_pending, pending_pp_value = value_pending 

而且它更明智的做法是使用另一种名称为您的别名，你总不是使用相同的名称您现有的字段名称，如value_pending。不妨将它更改为TotalValuePending，以便它会：

UPDATE SET pending_pp_volume = tonase_pending, pending_pp_value = TotalValuePending
