JavaのJDBCコードを作成してレコードのテーブルを入力していますが、エラーが発生しましたjava.sql.SQLException：ORA-01438：値が指定より大きいこの列に許容される精度はです。私の理解では、私はのクラスにStudentDAOという文でエラーが発生しました。int result = pst.executeUpdate（）;はここレコードを挿入中にJDBC Javaでエラーが発生する

Oは、メッセージがprety明らかだと思います。 – Jens
という大きすぎるカラムに値を追加し、テーブル定義（投稿していないのでできないので）を見て、それがどのカラムであるかを知ることができるはずです。 –
これは私のテーブルを作成するために使用したSQLコマンドです - create table Student17（stdid number（3）プライマリキー、name varchar2（100）、sub1 number（2）、sub2 number（2）、sub3 number（2） 、総数（3）、平均回数（3））。 –
