public class TestingData extends Activity       Called when the activity is first created      Override public void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout main        SQLiteDatabase db      db   openOrCreateDatabase           TestingData db            SQLiteDatabase CREATE IF NECESSARY           null                    then see this link link

I recommend to create a method just for inserting and than use ContentValues  For further info https   www tutorialspoint com android android sqlite database htm  public boolean insertToTable String DESCRIPTION  String AMOUNT  String TRNS        SQLiteDatabase db   this getWritableDatabase         ContentValues contentValues   new ContentValues        contentValues put  this is  DESCRIPTION       contentValues put  5000  AMOUNT       contentValues put  TRAN  TRNS       db insert  Your table name  null contentValues        return true

Since you are new to Android development you may not know about Content Providers  which are database abstractions  They may not be the right thing for your project  but you should check them out  http   developer android com guide topics providers content-providers html

I see it is an old thread but I had the same error   I found the explanation here   http   developer android com reference android database sqlite SQLiteDatabase html     void execSQL String sql    Execute a single SQL statement that is NOT a SELECT or any other SQL statement that    returns data       void execSQL String sql  Object   bindArgs          Execute a single SQL statement that is NOT a SELECT INSERT UPDATE DELETE

You ll find debugging errors like this a lot easier if you catch any errors thrown from the execSQL call  eg    try           db execSQL Create CashBook         catch  Exception e             Log e  ERROR   e toString

Seems odd to be inserting a value into an automatically incrementing field   Also  have you tried the insert   method instead of execSQL   ContentValues insertValues   new ContentValues    insertValues put  Description    Electricity    insertValues put  Amount   500   insertValues put  Trans   1   insertValues put  EntryDate    04 06 2011    db insert  CashData   null  insertValues
