Question

エラー：テーブル "salesorderheader"の挿入または更新が外部キー制約 "salesorderheader_customerid_fkey"に違反しています 詳細：キー（customerid）=（29825）がテーブル "customer"に存在しません。 **********エラー**********

しかし、29825はCustomer.txtファイルにあります。

あなたはCustomerテーブルを移入しませんでした：

COPY Customer 
FROM 'C:\Users\Public\Vaseis\Customer.txt' DELIMITER ',' CSV HEADER; 

COPY SalesOrderHeader 
FROM 'C:\Users\Public\Vaseis\SalesOrderHeader.txt' DELIMITER ',' CSV HEADER;
