Answer 1

Just do:

db.delete(DATABASE_TABLE, null, null);

Note that using rawQuery should work, but can be a potential security risk.

EDIT:

About the problem you have when you use

db.execSQL

Read the documentation, it says you should not use execSQL with INSERT, DELETE, UPDATE or SELECT

Answer 2

Consensus is to drop and recreate the table, or you can use DELETE FROM tbltask which uses a performance operation similar to a TRUNCATE on other dbs.

Answer 3

 getWritableDatabase().execSQL("DELETE FROM " + "contacts" + ";");

Here contacs is my table name.. Try it..It works for me..

Answer 4

Delete all values from database table use this method in database.

private SQLiteDatabase odb;
public void deleteallvalues(){
     odb.delete(TABLE_NAME,null,null)
}

this work fine.
