Comment on PostgreSQL is Powerful, Confuses Newbies by alexhochberger

Because removing row 2 doesn’t create a reason to eliminate row 3. The only rule is that the numbers are unique.

If you had 15 Billion lines in a table, and you removed one of them, you want the database to renumber 15 billion lines?

If you want to know the number of rows, do, SELECT count(*) FROM tablename; and you’ll get the count. If you want the last inserted one that isn’t deleted, you do SELECT max(no) FROM tablename, and those results may not be the same.

I have a question, why if I delete a row, then auto_increment (serial) not re-number,

example :

no | name
_________
1 | jack
2 | smith
3 | less

then I delete row number 2, why column no became like this :

no | name
_________
1 | jack
3 | less

thanks

Comment on Ban on Internships a Bad Idea by Becca

Becca — Fri, 07 May 2010 23:54:29 +0000

I never really thought about it from the perspective “interns should get paid minimum wage”. I think most major corporations pay their co-ops and interns. Most of the unpaid ones I know work either for politicians or non-profits/NGOs. (Hm, if they do work for a non-profit, should they be able to write off the minimum wage they should’ve been getting paid as an in-kind donation?) Most of the students I Know who worked unpaid internships either came from extremely well off families or were leveraged off of huge amounts of student loans. The first don’t really need my help or sympathy, the latter should not be working for free. Anyway. I don’t know. Yes, I think its wrong for a for-profit company to use free labor even int he form of interns. I guess it depends what the intern is doing, if the intern is shadowing an employee, well, that could be free. If you’ve got your intern filing things and answer phones and hacking computer code, well, that’s a real job, and someone should get paid for that.
