Question

I’m working on an android project and I have to delete all records in my table:

 public void deleteAll(){
    SQLiteDatabase db=this.getWritableDatabase();
    String req="delete * from "+ TABLE_ENIGME;
    db.execSQL(req);
}

But when I call my function deleteAll this exception is reveled :

 android.database.sqlite.SQLiteException: near "*": syntax error: delete * from enigme2

So why ” * ” is innapropriate?

Answer 1

Please have a look at http://www.sqlite.org/lang_delete.html.
Delete does not accept wildcard.
Use

Delete From <table name>

instead
