If you want to insert a record with a specific value in that column, *and* you want the value to be treated like an AUTO_INCREMENT value, so that LAST_INSERT_ID() will return that value, then do this: INSERT INTO customers (customer_id VALUES(LAST_INSERT_ID(10)); Thank you very much indeed for this succinct explanation (and the workaround). This makes sense now, so another small corner of MySQL has been illuminated for me! Thanks again.

last_insert_id gives 0
I am running MySQL 3.23.41-17 on a stock SuSE 7.3 install. I have a table customers with an auto-incrementing primary key customer_id. If I insert a record: mysql insert into customers(customer_id) values (10); and then ask for the last insert: mysql select last_insert_id(); (which I thought was the correct syntax) I get the response 0. If I ask: mysql select last_insert_id() from customers; I get as many zeros as there are records. If I ask: mysql select last_insert_id(customer_id) from customers; I get the ids for all the records. If I then ask: mysql select last_insert_id(); I get the last record inserted (which was what was supposed to happen, I thought), BUT if I insert another record and repeat: mysql select last_insert_id(); I get the same number as the last time I asked - ie the last but one. However, if I then ask: mysql select last_insert_id(customer_id) from customers; followed by: mysql select last_insert_id(); I get the most recently-added record number. Could some kind person on the list please explain what is happening here, and why the standard syntax does not give the results I expect? Thank you.

MyODBC availability
Does anyone know why it is that the MyODBC authors prefer not to allow that to be distributed in the unixODBC package, or with distros (eg the SuSE CDs don't contain it)? Is it a licensing issue, something to do with the ODBC spec, or just plain don't want to do that, so there (which, I hasten to add, is perfectly acceptable)? Just curious.

Fwd: Re: newbie. can't run safe_mysqld
Hi Mike This command executes and immediately ends: safe_mysqld --log [2] 855 root@linux:/var/lib/mysql Starting mysqld daemon with databases from /var/lib/mysql 04 07:45:16 mysqld ended This command seems to run quite nicely: safe_mysqld --skip-grant-tables Now the manual informs me to From mysql, manually execute the SQL commands in mysql_install_db. 1) Huh ? (I am a Linux newbie - don't know how) 2) Can the mysql_install_db script be troubleshot and corrected ? 3) Will a newer version of MySQL run better on my SuSE Linux 7.1 machine ? First, calm down. I gather you're running SuSE 7.1. In that case, do you have the CDs? MySQL can be a bit of a bind for beginners (I should know) until you get used to it, and it is easiest to get started with the version on the CDs. Then, once you are used to it, you can update to new versions (or a new boxed version of SuSE, which will include them). I am on 7.3, but looking at my notes for 7.1 I see I had the same problem. The solution is probably similar. Basically, you need to run mysql_install_db first, to create the user db that MySQL needs in order to start the daemon - that is why it is exiting unstarted. So, install your packages. Then go to wherever they are installed (if you are using the SuSE CDs, this was in /usr/bin). As root, run: mysql_install_db (running as user will give errors). You should get messages about the various tables being created. Then (as root) run: safe_mysqld You should get no daemon ended message. You then need to set the password for the root user (mysqladmin -u root password whatever). This is the standard method, but I have found that it can end up giving you error messages about root@localhost not being allowed access, which are confusing to a new user. (The errors are because you also need to specify the host). So what I do is log on to MySQL without setting the root password (mysql), and then run: update user set password=password(whatever) where user=root; and then: flush privileges; Exit, and log in again using root and the password. The above sets the same password for both host entries (hostname and localhost), so you don't have any hassle. To see what I mean, logon as root and run: use mysql; select user,host,password from user;. You should then delete the blank users (delete from user where user=;, and then: flush privileges;). To get MySQL to start automatically at boot, use YaST (System Admin - Change config file) to set START_MYSQL to yes. Try this, and see how it goes. You won't want to go back to Access, believe me! You can do simple queries really easily in Access, but to do anything more you need to use SQL in some form, and you might as well use a proper SQL db for that. As GIU clients for MySQL, I would recommend KMySQL on Linux, and MySQLFront on Windows. If you have further issues, post them to the list, and also separately to me.

Re: PHP+MYSQL: unable to select database
One of three issues: 1 - the db is not set up correctly; 2 - the user is not set up correctly; 3 - the PHP script is not calling the db properly - this could be due to wrong syntax, misnaming of the db table, or incorrect username parameters. You would need to post some more info, in particular the script. I would start at 1 at this point - have you set up the db on your webserver according to the instructions that came with the guestbook script?

Re: PHP+MYSQL: unable to select database
Hi Josep We have to be clear about definitions. You seem to be making a couple of mistakes here: 1 - guestbook.sql is not the db, but probably a script to create the db (you can check by opening it in a text-editor - it will probably have a CREATE TABLE statement at the top, then the field definitions, then perhaps some INSERT statements); 2 - the db does not usually reside in the user's webroot. This can all be sorted out, but you will have to proceed one step at a time. First, what is the guestbook script you are using? Second, have you uploaded all the relevant files to your webserver, and made any configuration changes necessary? Third, how do you access MySQL on your webserver - via telnet/SSH, or via MyPHPAdmin? If you're not sure about the third, stop there and come back. Fourth, have you created the db using MySQL on the webserver? This usually involves: * uploading the .dmp or .sql to the server (not necessarily to the webroot, but perhaps to your FTP area); * creating a db: mysqladmin -uroot -p create mydatabase; * logging onto MySQL and populating the database from the supplied script: mysql -uroot -p mydatabase /path/to/database.sql. If you haven't done this, come back. We'll take it from there. Best wishes Kevin On Monday 10 December 2001 11:44, you wrote: I think didn't set the database correctly.

Re: lost in the Land of Oz Parking Lot
Hi Jason On Friday 09 November 2001 00:26, [EMAIL PROTECTED] wrote: I am lost. I am a very VERY green newbie, and I am struggling on just how to begin. Basically, I have bought a book, entitled, PHP and MYSQL Web Development . , I have downloaded mysql-3.23.43.tar.gz, the install for windows document (yes I have not even made it passed the Install! Oh I am PATHETIC!) says to use Setup.exe for windows. The problem is I can not find that file anywhere. This is a very good book indeed. But since you confess to being an absolute beginner (aren't we all?), I wonder whether I might point you in the direction of a book specifically for beginners. It is PHP Fast and Easy, by Julie Meloni, pubished by PrimaTech. It comes with a CD with all the stuff on it (although probably a bit dated by now - it's been out for a year), and detailed install instructions (everything went on first-time on Win95, once I'd updated the winsock to v2, so Win98 should have no problems at all). Only about 10 or 11 different types of page are covered, but they each have step-by-step walkthroughs, and I was able to read the whole book through without getting lost. Once you've done that, you'll have a good basis for going on to Welling and Thomson.

v3: delete based on select
