Answer 1

Use execSQL() for such SQL and not rawQuery() .

rawQuery() just compiles the SQL but does not run it. You'd need to call one of the move...() methods on the returned Cursor to execute a step of the compiled SQL program.

execSQL() both compiles and runs the SQL program.

There's also possibly a syntax problem with your literals - use parameters ie ? placeholders in SQL and String[] bind arguments to be safe.

Answer 2

try to use this:

ContentValues values = new ContentValues();
values.put("Recieve", str);
db.update("ChallanItems", values2, "ItemNo = ?", new String[] { code });

Answer 3

To update sqlite query change

 Cursor c = myDataBase.rawQuery(qry, null);

to this

myDataBase.execSQL(qry);
