How do I drop and recreate a table with updated information?
For example; I have a table in my application with 5 records.
ID Entry
1 a
2 b
3 c
4 d
5 e
Now when I delete a record lets say, ID 3 the table becomes
ID Entry
1 a
2 b
4 d
5 e
How can I drop it, and recreate it to become this:
ID Entry
1 a
2 b
3 d
4 e
Actually the deletion is controlled by the user so any record can be deleted at any time.
You could do following: delete the row You want to delete:
public boolean deleteRow(int id)
{
return db.delete(YOUR_TABLE, ROW_ID + "=" + _id, null) > 0;
}
read remaining entries (only entries, not the id) into an ArrayList, drop Your table:
db.execSQL("DROP TABLE IF EXISTS " + YOUR_TABLE);
and recreate Your table. Then the ID Numbers will be again from 1-XX in Order
