Reading integers from SQLite database returns 0?

manpreet Best Answer 3 years ago

In my Android application, I have an SQLite database that stores a students grade information. I am able to read in the category of the grade correctly but for some reason when i try to read in the grade itself resCurs.getInt(gradeIndex) returns 0 every time even though the grade value in my database is clearly not 0. Any help would be greatly appreciated as I see nothing wrong with my code

GradeDBOpenHelper.java

package bcs421.jorgeramirez.hwk.gradeapp.adv;

 import android.content.Context;
 import android.database.sqlite.SQLiteDatabase;
 import android.database.sqlite.SQLiteDatabase.CursorFactory;
 import android.database.sqlite.SQLiteOpenHelper;

 public class GradeDBOpenHelper extends SQLiteOpenHelper {

public static final String DATABASE_NAME = "GradeData.db";
public static final String DATABASE_TABLE = "GradeData";
public static final int DATABASE_VERSION = 1;

public static final String KEY_ID = "_id";
public static final String COLUMN_CAT = "category";
public static final String COLUMN_NUM = "itemnumber";
public static final String COLUMN_DESC = "description";
public static final String COLUMN_GRD = "grade";
public static final String COLUMN_DATE = "date";

static final String DATABASE_CREATE =
        "CREATE TABLE " + DATABASE_TABLE +  "(" + 
        KEY_ID + " integer primary key autoincrement, " +
        COLUMN_CAT + " varchar(20), " +
        COLUMN_NUM + " integer, " +
        COLUMN_DESC + " varchar(255), " +
        COLUMN_GRD + " integer, " +
        COLUMN_DATE + " varchar(255));";

private static final String STUDENT_SELECT =
        "SELECT * FROM " + DATABASE_TABLE + ";";

static final String GRADE_INSERT_1 =
        "INSERT INTO " + DATABASE_TABLE + " VALUES (NULL, 'Homework', 1, 'Assigment 1 - Schedule App', 100, '02/10/2015');";

static final String GRADE_INSERT_2 =
        "INSERT INTO " + DATABASE_TABLE + " VALUES (NULL, 'Quiz', 1, 'Quiz - Syllabus', 100, '02/10/2015');";

        "INSERT INTO " + DATABASE_TABLE + " VALUES (NULL, 'Lab', 1, 'Lab Ch1 - Hello Yankees', 100, '01/28/2015');";

static final String GRADE_INSERT_4 =
        "INSERT INTO " + DATABASE_TABLE + " VALUES (NULL, 'Lab', 2, 'Lab - Hello World', 100, '02/04/2015');";
