Hi,
I have a question about autoincremend id:
If I have an autoincrement id set on my first column field of my table and I
have the
following entries:
1
3
And then I make a INSERT INTO foobar VALUES(''); , the next field would be
automatically 4:
1
3
4
Is there a possibility to take a free ID

Lots of ways round this. Instead of deleting records, add a boolean
deleted flag. All selects then need to add and deleted = 0. But you can
find a (random) deleted row with select id from table where deleted = 1

So I must do a big SELECT and then check my self every time (for each
INSERT),
which IDs are free?
