如何同时插入和更新

如何解决如何同时插入和更新

我有一个包含 1 个以上值的源表，我的目标是在执行查询的同时插入和更新我的目标值。

首先，如果源表在目标表中找到相同的值，则更新它，但如果不存在，则插入数据。

显然，当我使用 MERGE 时，它只会更新相同的值，但不会插入新值：

MERGE merchant_negative_db_copy as MasterTb
USING merchant_negative_db_History AS SourceTb
      ON SourceTb.id_merchant = MasterTb.id_merchant

WHEN MATCHED THEN 
    UPDATE SET MasterTb.Nama_Pemilik = SourceTb.Nama_Pemilik,MasterTb.Alamat_Pemilik = SourceTb.Alamat_Pemilik,MasterTb.Telp_Merchant = SourceTb.Telp_Merchant,MasterTb.Nama_Merchant = SourceTb.Nama_Merchant,MasterTb.Alamat_Merchant = SourceTb.alamat_merchant,MasterTb.upload_by = SourceTb.upload_by,MasterTb.upload_date = SourceTb.upload_date

WHEN NOT MATCHED THEN
    INSERT (Nama_Pemilik,Alamat_Pemilik,Telp_Merchant,Nama_Merchant,Alamat_Merchant,id_merchant,upload_by,upload_date,flag_merchant)
    VALUES (SourceTb.Nama_Pemilik,SourceTb.Alamat_Pemilik,SourceTb.Telp_Merchant,SourceTb.Nama_Merchant,SourceTb.alamat_merchant,SourceTb.id_merchant,SourceTb.upload_by,SourceTb.upload_date,0);

关于如何同时插入和更新的任何建议，逐个检查数据是最后一个选项，除非可以使用合并？

编辑

我尝试更改“ON”条件但显示一些错误（值已存在并添加新值）

MERGE merchant_negative_db_copy as MasterTb
USING merchant_negative_db_History AS SourceTb
ON MasterTb.Nama_Pemilik = SourceTb.Nama_Pemilik AND MasterTb.Alamat_Pemilik = SourceTb.Alamat_Pemilik
WHEN MATCHED THEN 
    UPDATE SET MasterTb.Nama_Pemilik = SourceTb.Nama_Pemilik,MasterTb.upload_date = SourceTb.upload_date
WHEN NOT MATCHED THEN
    INSERT (Nama_Pemilik,0);

错误

The MERGE statement attempted to UPDATE or DELETE the same row more than once. This happens when a target row matches more than one source row. A MERGE statement cannot UPDATE/DELETE the same row of the target table multiple times. Refine the ON clause to ensure a target row matches at most one source row,or use the GROUP BY clause to group the source rows.
