Is it possible to have multiple auto increments in one column? Say I
have two tables...
1. table 'messageboards' with fields ('id' , 'name')
2. table 'messagethreads' with fields ('id' , 'messagethread' ,
'messageboard_id')
The 'messagethreads.id' column could have multiple auto increments.
Then I could easily query a messageboard with ("SELECT * FROM

Hi all,
I have a table with an “autonumber” primary key field that also acts as
a foreign key in 2 other tables. I would like to programmatically add a
new record to the first table and the other 2 child tables. The reason
for doing this is to copy one complete record (parent and child table
records) into a new record so the user can make a few modifications.
So how do I determine what will be the next auto-generated number for my...

I retrieve a table with only 2 columns. One is a auto-generated primary key
column and the 2nd is a string. When I add a new row to the dataset to be
updated back to the database. What should I do with the 1st column ? (Below
I have a "1" in place for now). Also, Does the datase.AcceptChanges();
updates the changes to the database? Which command do I use to update the
changes in dataset back to the Access database table? Thanks, Alpha...

Before I started to create table, etc to track unique form field record
number assigments I thought I'd check to see if there is now a better way to
do this in .NET.
I have a parent form (table) and children form (table). Relationship equals
one to many. I'd like to auto number the fields accordingly and traditionaly
I assign a unique number based on a table value that I retrieve + 1.
i.e.
Parent record field value = 1

I have 2 virtually identical tables and wish to move data between them.
Basically one table is called "live_table" and the other is named
"suspended_table" and the only difference is that the primary key in the
"suspended_table" is an auto incremented integer where as "live_table"
primary key is just a standard integer.
Here's the life-cycle:
1. Record gets entered into "suspended_table"
2. Record checked and then inserted into...

Is it true that if I split my access database in backend and frontend and I
implement custom auto increment for the ID fields, that my database is ready
to be used in a multi-user environment? I found a zillion messages about
auto increment and read some of them but it's confusing. Can someone point
me to a simple custom auto increment example that I can download?
Thank you,

Hello scripters -
OS: Mac OSX
Language: PHP w/ MySQL database
I've created an insert page where a user inputs his info, which then goes to four different tables in a MySQL database. The tables are all linked with the field 'member_id', which is an auto-increment field in the parent table ('members').
I've been able to input multiple records into the other three tables 'specialty_groups', 'committee_interest' and 'committee_member'...

Hello fellow authoring.stylesheets colleagues,
Can someone please explain why the bottom margin of the last inflow
block-level child in an overflowed parent should not have its margin
reachable. I read and re-read carefully the CSS 2.1 spec and I just
can not see why.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
