私は保険カードを保存できるアプリを書いています。ユーザーが情報を入力し、データベースに保存されています。アプリは以前のインシデントのリストで起動します。これが問題の発生場所です。それは私に "driverone"の列が存在しないことを伝えています。SQLiteが列が存在しないことを伝えています
私はプログラミングが新しく、SQLiteは非常に新しいので、すべてのアドバイスは大歓迎です。私はこのトピックがここまで来ていることを知っています。私はその回答を検索して、何が起こっているのか把握できません。ここで
は、私は私のデータベースを定義するコードです：私は私のデータベースを作成する場所
public class DbSchema {
public static final class CrashTable {
public static final String NAME = "crash";
public static final class Cols {
public static final String UUID = "uuid";
//TODO: "column 'driverone' does not exist...fix it
public static final String DRIVER_ONE = "driverone";
public static final String INSCO = "insco";
public static final String POLICY = "policy";
public static final String PHONE = "phone";
public static final String EMAIL = "email";
//public static final String DRIVER_TWO = "driver_two";
//public static final String INSURANCECOMPANY_TWO = "insurancecompany_two";
//public static final String POLICYNUMBER_TWO = "policynumber_two";
//public static final String TELEPHONENUMBER_TWO = "telephonenumber_two";
//public static final String EMAILADDRESS_TWO = "emailaddress_two";
//public static final String DATE = "date";
}
}
}
そして、ここです：
private static final String CRASH_TABLE_CREATE_STATEMENT = "create table " + CrashTable.NAME + "(" +
" _id integer primary key autoincrement, " +
CrashTable.Cols.UUID + ", " +
//CrashTable.Cols.ID + " integer primary key autoincrement, " +
CrashTable.Cols.DRIVER_ONE + ", " +
CrashTable.Cols.INSCO + ", " +
CrashTable.Cols.POLICY + ", " +
CrashTable.Cols.PHONE + ", " +
CrashTable.Cols.EMAIL + ", " +
");";
し、エラーが発生した場所です。
public class CrashCursorWrapper extends CursorWrapper{
public CrashCursorWrapper(Cursor cursor) {
super(cursor);
}
public Crash getCrash() {
String uuidString = getString(getColumnIndexOrThrow(CrashTable.Cols.UUID));
String driverone = getString(getColumnIndexOrThrow(CrashTable.Cols.DRIVER_ONE)); <------ Error here
String insco = getString(getColumnIndexOrThrow(CrashTable.Cols.INSCO));
String policy = getString(getColumnIndexOrThrow(CrashTable.Cols.POLICY));
String phone = getString(getColumnIndexOrThrow(CrashTable.Cols.PHONE));
String email = getString(getColumnIndexOrThrow(CrashTable.Cols.EMAIL));
//String theirName = getString(getColumnIndex(CrashTable.Cols.DRIVER_TWO));
//String theirInsCo = getString(getColumnIndex(CrashTable.Cols.INSURANCECOMPANY_TWO));
//String theirPolicy = getString(getColumnIndex(CrashTable.Cols.POLICYNUMBER_TWO));
//String theirTelephone = getString(getColumnIndex(CrashTable.Cols.TELEPHONENUMBER_TWO));
//String theirEmail = getString(getColumnIndex(CrashTable.Cols.EMAILADDRESS_TWO));
//long date = getLong(getColumnIndex(CrashTable.Cols.DATE));
Crash crash = new Crash(UUID.fromString(uuidString));
crash.setYourName(driverone);
crash.setInsCo(insco);
crash.setPolicy(policy);
crash.setTelephone(phone);
crash.setEmail(email);
//crash.setTheirName(theirName);
//crash.setInsCo_Two(theirInsCo);
//crash.setPolicy_Two(theirPolicy);
//crash.setTelephone_Two(theirTelephone);
//crash.setEmail_Two(theirEmail);
// crash.setDate(new Date(date));
return crash;
}
}
