Re: yesterday I posted this and you all aksed for more info so ........

Just like I thought, session_id is a varchar. Varchars alphabetize like this:
0
1
10
11
2
3
4
5
6
7
8
9
So 9 is the max, which isn't what you want. Make session_id a number, or make sure you always zero-pad it, or initialize it to "aaaaaaaaaa", or something.

Update: Don't know if it's possible two copies of this script could run at the same time, but you might have a problem with two different sessions creating the same new session id at once. Might be better for you to do something like:

insert into sessions (session_id, session_date)
select max(session_id)+1, ?
from sessions

... or anything else that does proper locking.

Bad advice there man without slogan, i also gave it here Win32::ODBC insert question, but was corrected. One thing esolm is doing wrong, and princepawn hinted on(real close) is not using an AutoNumber field. It's Microsoft's answer to autoincrement. Anyway, why don't you just use MS Access to design your database, then you can get to business `CREATE TABLE sessions ( SESSION_ID bigint(20) NOT NULL auto_increment, SESSION_DATE datetime, FILE_ARCHIVE varchar (25), constraint pk_session PRIMARY KEY (session_id) ); or to be MS Access Specific CREATE TABLE sessions ( SESSION_ID bigint(20) NOT NULL AutoNumber, SESSION_DATE datetime, FILE_ARCHIVE varchar (25), constraint pk_session PRIMARY KEY (session_id) );` [download] btw, here are some MS Acces SQL related links i dug up when I was messing with it 2 months ago: http://officeupdate.microsoft.com/articlelist/o2kAccessArticles.htm http://msdn.microsoft.com/library/default.asp?URL=/library/techart/acacclinks.htm http://support.microsoft.com/support/kb/articles/Q140/6/36.asp http://support.microsoft.com/support/kb/articles/Q208/6/79.asp http://msdn.microsoft.com/training/courseware/1539.asp http://officeupdate.microsoft.com/2000/downloaddetails/sp2upd.htm http://support.microsoft.com/support/serviceware/access/acc2000/ and some article titles you should google, cause i just saved them to my hd, and don't have the links: `Advanced Microsoft Jet SQL for Access 2000.html Fundamental Microsoft Jet SQL for Access 2000.html Intermediate Microsoft Jet SQL for Access 2000.html Tips and Tricks for Access 2000.html Fundamentals of Relational Database Design.html A Simple Guide to Five Normal Forms in Relational Database Theory.html` [download] ___crazyinsomniac_______________________________________ `Disclaimer: Don't blame.
