Depending on your MySQL version you could use a subquery by combining the
two queries you mentioned, for a fairly straight-forward query.
http://dev.mysql.com/tech-resources/articles/4.1/subqueries.html

You could read about optimizing subqueries
Unfortunately, I'm on 4.0.x so sub-queries are out. And yeah, I
should get my host to upgrade but we both work for the government
so that isn't happening. ;-)
Any other thoughts.

What about a union? Does mySql 4.0.x support it?
select * from blank where tchar_10 != ''
union all
select * from blank where tchar_10 = ''

This is a little weird looking, but should do the job. Remember that items in
your 'order by' can be manipulated conditionally. In this case, I'm looking
for NULL as well as '' (empty) and changing it to something that should come
after all your normal alphabetical values, but it doesn't

In case the blank is a null or is really a blank:
select * from blank where tchar_10 is not null and tchar_10 != ''
union all
select * from blank where tchar_10 is null or tchar_10 = ''

You shouldn't have to do that. the IFNULL() handles all that. If the item is
null, it returns an emptry string ''. If it's blank/empty, it returns an empty
string. This is just used for the comparison = ''. This determines if it's
empty or null and if so, returns
I cannot connect to my MSSQL server.
I use the following connection string:

I haven't tried the union method the query i have is actually
quite a bit more complicated than just a simple select * from a
single table, so while it may work, it might take a while to write it
if I am reading all this right.
But yes, the ifnull() method works just fine. Thanks for

Hi,
The below mentioned code works fine. Connects to the database, fetches the
result, and displays neatly in a table. If there is no data then it jumps to
the if condition and displays the error message. BUT if the 'if' condition
is running and no data is present the Table headings and the

do it here.
After doing the connection and database selection, this is how we handle stuff

$query = select * from
Hi,
there's no 'logic' error at all that I can see. It's more a design
error as it doesn't do the job the way that you describe it at all.
What actually happens is that the starting HTML (heading and table
start) is output before the database is even contacted, so there's no
way for you to
Hi everyone,
My 1st attempt at creating a login script isn't going so good, so
hopefully someone can help me out.
The login script itself works fine but when I include it into a web
page, the login.php script shows up but the entire index.html page also
shows up.
I just want people to log in
why not just create a simple single logon page and not include itthen on
sucessful login, redirect the user to the index page?

If I do it that way, can't someone get into the index page if they link

After that, any page you want to protect you just put one line at the top

there.
