How to update KEY_ROWID after deleting a row in SQLite database

Question

How can I update the KEY_ROWID number in SQLite database after deleting a row from the database? CASE 1: For example, if I have five rows in the database, maximum KEY_ROWID is

Answer 1

You can reset the sequences if you're deleting all data;

DELETE FROM test;
DELETE FROM sqlite_sequence WHERE name='test';

As for renumbering primary keys when there is still data in the table, I'd sincerely advise against it, since any foreign keys that reference your table will be broken.

Answer 2

The solution is that rewriting the table with a new array or list ;

reWriteTable is will allow automatic sorting of rows.

private void reWriteTable(){
    if(db.listOfDate().size()!=0){
        String[] name =new String[db.listOfDate().size()] ;
        String[] note=new String[db.listOfDate().size()] ;
        String[] date =new String[db.listOfDate().size()];
        String[] time =new String[db.listOfDate().size()];
        String[] total =new String[db.listOfDate().size()];

        for(int i=0;i<db.listOfDate().size();i++) {
            String currentString =db.listOfDate().get(i) ; // 0,1,2,3
            separated = currentString.split("-");  //Take words between "-" from Database 
            name[i]=separated[1];
            note[i]=separated[2];
            date[i]=separated[3];
            time[i]=separated[4];
            total[i]=separated[1]+"-"+separated[2]+"-"+separated[3]+"-"+separated[4];
        }
        db.deleteTable();
        //db=new Database(MainActivity.this);
        for(int i=0;i<total.length;i++) {
            Log.d("TAG",String.valueOf(total.length)+"  "+total[i]);
            String currentString =total[i] ; // 0,1,2,3
            separated = currentString.split("-");  //Take words between "-" from Database 
            name[i]=separated[0];
            note[i]=separated[1];
            date[i]=separated[2];
            time[i]=separated[3];
            // total[i]=separated[1]+"-"+separated[2]+"-"+separated[3]+"-"+separated[4];
            db.addData(name[i],note[i],date[i],time[i]);
        }
    }

}

Define deleting table in Database.java ;

 protected void deleteTable(){
        SQLiteDatabase db=this.getWritableDatabase();
        db.execSQL(" drop table if exists " + TABLO_UYGULAMALAR + ";");
        onCreate(db);

    }
