I have a question about the following PHP script - I got it off a web
site tutorial on how to count users logged into your site - my
question is the $PHP_SELF variable - it writes the name of the web
page to the 'file' field in the table - I don't understand why it is
doing that - I mean, isn't the SELECT DISTINCT statement only pulling
those records from that one web page? I guess I just don't follow what
it is doing with that SELECT...

Hi,
I have a table that contains log data, usually around a million records. The
table has about 10 columns with various attributes of the logged data,
nothing special. We're using SQL Server 2000.
Some of the columns (for example "category") have duplicate values
throughout the records. We have a web page that queries the table to show
all the unique columns, for example:

My boss has been adamant that SELECT DISTINCT is a faster query than
SELECT all other factors being equal. I disagree. We are linking an
Access front end to a SQL Server back end and normally are only
returning one record. She states that with disctinct the query stops
as soon as it finds a matching record. Both of us are relative novices
in database theory (obviously).
Can someone help settle this?

Hello everyone,
I've tried both DISTINCT or DISTINCTROW in the following query in a PHP
script. But the results still contain duplicate records as show below.
DISTINCT works fine on single selected fields. But in this case, the
SELECT statement has multiple fields. Is this the correct way to use
DISTINCT on multiple fields?
$qry = odbtp_query("SELECT DISTINCT WebGradStudents.IDNo AS studentID,
LastName, FirstName, WorkPhone,...

Hi folks
Im trying to do a simple query involving the distinct keyword and an
access 2000 db, but have been frittering with it for amost and hour
and a half and I cant make it work.
This is the SQL I would run if it were valid syntax, but it's not:
Select COLOR1, COLOR2, distinct DESC from COLORS;
TABLE COLORS

I'm trying to write a query that will select a distinct count of more
than one field. I have records that display user productivity. Each of
the records have a time associated with it and I want to be able to
tell the distinct count of the products numbers and of the pallets ID
that they worked with. Do need to work out some sort of sub-query to do
this?

I would like to pull unique records of a SINGLE column but not the other related columns. When I use DISTINCT, it pulls up all the records which are unique across the columns. Here is the code....
SELECT distinct columnA,columnB,columnC
FROM Table
ORDER by columnA,columnB,columnC;
What I would like to see, is Distinct records from column A, and not from other columns. But I would like to have the records from other columns to show up...
