Question

My application is unable to create a simple table. Please see the below code,

DatabaseHandler.java

public class DatabaseHandler extends SQLiteOpenHelper {

private static final int DB_VERSION = 1;
private static final String DB_NAME = "PASSENGER_INFO_DB";
private static final String TABLE_NAME = "PASSENGER_INFO";
private static final String TABLE_COLUMN_SEAT_NO = "SEAT_NO";
private static final String TABLE_COLUMN_NAME = "NAME";
private static final String TABLE_COLUMN_AGE = "AGE";
private static final String TABLE_COLUMN_GENDER = "GENDER";
private static final String TABLE_COLUMN_FOOD_PREF = "FOOD_PREF";

private static final String CREATE_PASSENGER_INFO_TABLE = "CREATE TABLE IF NOT EXISTS "
        + TABLE_NAME + " ( " + TABLE_COLUMN_SEAT_NO
        + " TEXT PRIMARY KEY, " + TABLE_COLUMN_NAME + " TEXT, "
        + TABLE_COLUMN_AGE + " INTEGER, " + TABLE_COLUMN_GENDER
        + " INTEGER, " + TABLE_COLUMN_FOOD_PREF + " TEXT" + ")";

public DatabaseHandler(Context context) {
    super(context, DB_NAME, null, DB_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL(CREATE_PASSENGER_INFO_TABLE);
}
public void addPassengerInfo(PassengerInfo passInfo) {
    SQLiteDatabase addPass = this.getWritableDatabase();

    ContentValues values = new ContentValues();

    values.put(TABLE_COLUMN_SEAT_NO, passInfo.getM_seatNo());
    values.put(TABLE_COLUMN_NAME, passInfo.getM_name());
    values.put(TABLE_COLUMN_AGE, passInfo.getM_age());
    values.put(TABLE_COLUMN_GENDER, passInfo.getM_gender());
    values.put(TABLE_COLUMN_FOOD_PREF, passInfo.getM_foodPref());

    addPass.insert(TABLE_NAME, null, values);
    addPass.close();
}

in MainActivity.java

DatabaseHandler dbhandler = new DatabaseHandler(this);
addSeat = "1A";
passName = "NA";
passAge = 0;
passGender = -1;
passFoodPref = "NA";
dbhandler.addPassengerInfo(new PassengerInfo(addSeat, passName, passAge, passGender, passFoodPref));

(PassengerInfo.class has getter and setter methods for the fields)

And when I run this I’m getting the following error in logcat,

01-23 19:09:18.311: I/Database(1303): sqlite returned: error code = 1, msg = table PASSENGER_INFO has no column named SEAT_NO
01-23 19:09:18.370: E/Database(1303): Error inserting FOOD_PREF=NA NAME=NA AGE=0 GENDER=-1 SEAT_NO=1A

I have also checked the tables created in the database through adb shell, there’s no table with name PASSENGER_INFO.
Please help !

Answer 1

Have you tried increasing your database number? Also, try changing this line

+ TABLE_COLUMN_SEAT_NO
    + " TEXT PRIMARY KEY, "

to

+ TABLE_COLUMN_SEAT_NO
    + " TEXT, "

Add a separate column that will represent the rowId, update your database version number and re-run.
