この列は sqlite の価格です。私が使用しSELECT SUM(price) FROM example; ていますが、値が正しくありません。5 桁の数字の後に 67 の数字と 6 つのゼロと 1 が続きます。例: 34,456.670000001 。列は VARCHAR として作成されます。numeric(100) と Integer を試しましたが、値は同じままです。私は db の初心者なので、ガイドしてください。ありがとうございます。助けていただければ幸いです。

問題は、それらの文字列を数値に暗黙的にキャストして合計できるようにするときに、SQLite がコンマで数値を切り捨てることです。例えば：

sqlite> select '1,000' + '2,000';
'1,000' + '2,000'
3

コンマを削除するだけです。を使用replaceして、SQLite のデフォルトの型変換でそこから取得できるようにする必要があります。

SELECT SUM(replace(price, ',', '')) FROM example

例えば：

sqlite> select replace('1,000', ',', '') + replace('2,000', ',', '');
replace('1,000', ',', '') + replace('2,000', ',', '')
3000
