Yeah, right. And a hacker will not perform a portscan? And he will not

I hope it should work:
Select table1.ID from table1 left join table2 on table1.value=table2.value

Hi,
I have found this too. I think it is as a result of a change introduced in
4.0.18. From http://www.innodb.com/ibman.php#InnoDB.history :
MySQL/InnoDB-4.0.18, February 13, 2004
- Do not allow dropping a table referenced by a FOREIGN KEY constraint,
unless the user does SET
You will need root privilege in order to install and start MySQL. After
the installation, you may have to edit some confs to get MySQL to start
automatically at every boot. Thereafter, you can access the database
server be creating a user account for Mysql admin (root), plus unlimited
number
No you don't. Mysql will run perfectly happily as a standard user.
If you're installing from an rpm you will however need root privilege unless
the rpm is configured as relocatable - and the standard mysql ones aren't.
What you need to do is get yourself the source tarball (.gz) and not the
rpm.
The oracle and MySQL create syntax is not completely compabitable. You will
have to identify and correct the errors.
For example text data type in MySQL may need to be either VARCHAR(N) or
CLOB.

I tried doing that in one trial run, and I wasn't getting the $200 figure so
I gave up on that.
It seems like doing an order by that statement wouldn't have given me the

Don't know why that is though - in theory you should be right, I can try it
a bit more if your curious.

Is there any way to do this without creating another table?
Here is what I am trying:
mysql select count(distinct last_name) as LnameCnt, last_name from table_ABC group
What is the version of your mysql client? If it is pre 4.1 then it is likely being
bitten by the password length change from 4.0.xx to 4.1 from 16bytes to 41bytes.
You'll need to read the note on passwords in the 4.1 docs.
Hope this helps.
