I don't see any mistakes with my code, I browsed questions with the same issue but I couldn't solve
it, I tried upgrading the sql version from 1 to 2, but still same error.
Is there anything wrong with my code?

Inside onCreate you have:
+ place_street + " TEXT" + place_smallDesc + " TEXT,"
should be like below(missed colon), due to colon miss, both merged and table will have completely different column name than you are assuming.
+ place_street + " TEXT, " + place_smallDesc + " TEXT,"

I am attempting to assign the plan_recipe variable in the createPlan method with teh autoincremented id of the createPlanRecipe method. I've attempted to use the insert_last_rowid() method but am getting the error of Couldn't read row 0, col -1 from CursorWindow. Have I not done this correctly or is there another method I could use to do this?
Essentially how do I insert the id created from createPlanRecipe into variable plRecipe in createPlan()?

You must use an alias like id for the column that is returned by last_insert_rowid():
Cursor c = db.rawQuery("select last_insert_rowid() as id", null);
Then instead of:
if (c != null && (c.getCount() > 0)) {plRecipe = c.getInt(c.getColumnIndex("id"));}
do this:
if (c.moveToFirst()) {plRecipe = c.getInt(c.getColumnIndex("id"));}
Without the alias of the column, you should directly use 0 inside c.getInt():
if (c.moveToFirst()) {plRecipe = c.getInt(0);}
I am new to sqlite and i am trying to develop an application using sqlite, but I got stuck with an error
no such column: reminder.
I searched many sites but could not find out the problem. I do not know what all details I need to post. But I am getting error in my logcat like this.
Caused by: android.database.sqlite.SQLiteException: no such column: reminder (code 1): , while compiling: SELECT id, party_name, bank_name, reminder, expiry_date, reminder_date, cheque_number, amount FROM financeTBL ORDER BY idDESC

You're missing some commas from your CREATE TABLE statement, which means they'll be seen as one column rather than separate.
String CREATE_ALERT_TABLE = "CREATE TABLE " + Constants.TABLE_NAME + "("
+ Constants.KEY_ID + " INTEGER PRIMARY KEY,"
+ Constants.KEY_PARTY_NAME + "TEXT,"
+ Constants.KEY_CHEQUE_NUMBER + "TEXT" // <-- HERE
+ Constants.KEY_AMOUNT + "TEXT" // <-- HERE
+ Constants.KEY_EXPIRY_DATE + "LONG" // <-- HERE
+ Constants.KEY_REMINDER_DATE + "LONG" // <-- HERE
+ Constants.KEY_REMINDER + "Text,"
+ Constants.KEY_BANK_NAME + "TEXT);";
You're also missing spaces before the column type, so for example the reminder column will appear as reminderText in the constructed statement. I'd recommend reformatting your CREATE TABLE statement as so:
String CREATE_ALERT_TABLE = "CREATE TABLE " + Constants.TABLE_NAME + " ("
+ Constants.KEY_ID + " INTEGER PRIMARY KEY,"
+ Constants.KEY_PARTY_NAME + " TEXT,"
+ Constants.KEY_CHEQUE_NUMBER + " TEXT,"
+ Constants.KEY_AMOUNT + " TEXT,"
+ Constants.KEY_EXPIRY_DATE + " LONG,"
+ Constants.KEY_REMINDER_DATE + " LONG,"
+ Constants.KEY_REMINDER + " TEXT,"
+ Constants.KEY_BANK_NAME + " TEXT);";
One more space you need to add is in the ORDER BY part of this query:
Constants.KEY_ID + "DESC"
needs to be:
Constants.KEY_ID + " DESC"
In your onCreate You are forgetting commas . try this
public void onCreate(SQLiteDatabase db) {
String CREATE_ALERT_TABLE = "CREATE TABLE " + Constants.TABLE_NAME + "("
+ Constants.KEY_ID + " INTEGER PRIMARY KEY,"
+ Constants.KEY_PARTY_NAME + " TEXT,"
+ Constants.KEY_CHEQUE_NUMBER + " TEXT,"
+ Constants.KEY_AMOUNT + " TEXT,"
+ Constants.KEY_EXPIRY_DATE + " LONG,"
+ Constants.KEY_REMINDER_DATE + " LONG,"
+ Constants.KEY_REMINDER + " Text,"
+ Constants.KEY_BANK_NAME + " TEXT);";

Just update query
String selectQuery = "SELECT * FROM " + TABLE_USERS + " WHERE "
+ COLUMN_USERNAME + " = " + user.getUsername();
to
String selectQuery = "SELECT * FROM " + TABLE_USERS + " WHERE "
+ COLUMN_USERNAME + " = '" + user.getUsername()+"'";
Enclose your user.getUsername() value to single quotes because you define COLUMN_USERNAME as text.
If your string already contain quotes then it not work. Before adding user.getUsername() to query remove quotes from username as below
user.getUsername().replace("\'","''");
Your problem is here:
String selectQuery = "SELECT * FROM " + TABLE_USERS + " WHERE "
+ COLUMN_USERNAME + " = " + user.getUsername();
As user.getUsername() is text, you have to do the following:
String selectQuery = "SELECT * FROM " + TABLE_USERS + " WHERE "
+ COLUMN_USERNAME + " = '" + user.getUsername() + "'";
Cheers
Hi guys so here is my problem, I need to be able to access the unique ID of a row that is created because I created a second table that will "Connected" through the IDs. However here is my issue, whenever I try calling this method, my app crashes.. I was hoping the community could help me out here. Many Thanks.
public void addExerciseToDatabase(Exercises exercises){
SQLiteDatabase db = myDBHelper.getWritableDatabase();
ContentValues values = new ContentValues();
ContentValues nuValues = new ContentValues();
values.put(myDBHelper.COLUMN_BODYPARTNAME, exercises.get_bodyPart());
values.put(myDBHelper.COLUMN_EXERCISENAME, exercises.get_exerciseName());
long ID = db.insert(myDBHelper.TABLE_EXERCISES, null, values);
//FOR THE NEW TABLE VALUES
nuValues.put(myDBHelper.COLUMN_EXERCISENAME_ID, ID);
nuValues.put(myDBHelper.COLUMN_NUMSETS, exercises.get_numSets());
nuValues.put(myDBHelper.COLUMN_NUMWEIGHT, exercises.get_numWeight());
nuValues.put(myDBHelper.COLUMN_NUMREPS, exercises.get_numReps());
db.insert(myDBHelper.TABLE_EXERCISES_VALUE, null, nuValues);
db.close();
}

Update your query as your query not contains spaces in SELECT and FROM
String query = "SELECT " + myDBHelper.COLUMN_ID + " FROM " + myDBHelper.TABLE_EXERCISES + " WHERE " +
myDBHelper.COLUMN_BODYPARTNAME + " = " + bodyPart + " AND " +
myDBHelper.COLUMN_EXERCISENAME + " = " + exercise ;
Also can you post your logcat error.
public int getExerciseID(String exercise, String bodyPart) {
int exerciseID = 0;
SQLiteDatabase db = myDBHelper.getWritableDatabase();
String query = "SELECT " + myDBHelper.COLUMN_ID + " FROM " + myDBHelper.TABLE_EXERCISES + " WHERE " +
myDBHelper.COLUMN_BODYPARTNAME + " = " + bodyPart + " AND " +
myDBHelper.COLUMN_EXERCISENAME + " = " + exercise ;
Cursor c = db.rawQuery(query, null);
if(c.getCount()>0){
c.moveToFirst();
exerciseID = Integer.parseInt(c.getString(0));
/*exerciseID = c.getInt(c.getColumnIndex(myDBHelper.COLUMN_ID));*/
}
c.close();
db.close();
return exerciseID;

I'm working on a project using SQLite.
I did create my db a while ago and so on but yesterday i uninstall my app from the phone and tryed to run it again via eclipse and it seems that since that moment, it doesn't work anymore.

the java activity where i'm using the function getInfo:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
SQLHelper sqlHelper = new SQLHelper(this);
InfosModel infos = sqlHelper.getInfos();
Log.i("infos", infos.getMail());
}
The problem comes from the getInfos() function i believe.
My cursor isn't null but the function moveToFirst() fails but i don't know why and i don't know what to do to fix this since i've never had that problem before and my database was working well ..
thank you for the help :)
bottus.
edit : i tryed to see how many row i'm having in the infos table, there is zero row and that's why movetofirst() fail i believe but the behavior is exactly the same if i had a row in the table ..
Per the Android documents:
This method will return false if the cursor is empty.
So you must not have any data there, and you should manage appropriately. Check for typos, etc.
