Re: best way to copy a innodb table
Well, the easy way to chunk the inserts is by use of limit. Here is what I used for one of my projects: Insert ignore into t1 (f1, f2, f3) Select f1, f2, f3 from t2 limit 100, 100 Inserts 1M records at a time starting from 1M th record in t2 and you can keep incrementing this offset as you progress. This will help in monitoring the table inserts and at the same time move chunks of records from source table.

transitioning from ms sql
Hi, I have been using MS SQL for the last one year, however would not like to transition to mysql. At the first glance it looks very different from ms sql and the tools are also different. can someone tell me if there is any document which explains the equivalence and how i could port a lot of my queries, tables, views and stored procedures to my sql from ms sql.

Migrating Access databases to MySQL
Hello people ! I was hoping for some wisdom from the good folks on this list about moving databases from access to MySQL. I am aware of the brute force method of exporting in CSV format or tab delimited formats and using mysqlimport to move the tables. 1. I was wondering if there was a way to dump access databases in SQL queries like the mysqldump utility does ? 2. When exporting tab delimited values from access and using mysqlimport everything works fine except date columns. All the data moves except the date field which shows up zero's I mysql after I use mysqlimport. Does anyone have a clue on what might be happening? 3. Is there any way other than downloading some shareware third party programs to transfer my databases from access to MySQL ? I would appreciate any help at all. Thanks to everyone in advance !

I have seen free macros that create a text file you can import into mysql; it creates the tables and inserts all of your data. Do a google search, and if you still can't find anything let me know. bob -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

That's not two root accounts. What that means is this: The first line defines privileges for root connecting from localhost The second line defines privileges for root connecting from any remote host. Hence the %.

Certification Question
I took the MySQL core certification exam on the 2nd of January and Passed. I was just wondering when MySQL actually sends out the Certificate and other stuff they said they would send out? Does anyone here have any experience with this ? Thanks in advance.

I go to setup and run the setup and the status bar does not move much and the installation takes about 5 seconds and then it is done.

Also I have a my.cnf and ny.ini file in the proper places and I still have nothing going. I am confused and the manual I am finding is not clear enough on this. I included what the my.cnf and my.ini file looks like. And also included the error I am getting after installation. Also after MYSQL is installed should there not be some icons for things related to it, because I don't even have them.

Re: Newbie: need form to input records View report
If you want to build something like a web form you will need to use HTML and a scripting language. A common solution to do what you are asking is to use PHP. You will need to be familiar with PHP to go further. Go to http://www.php.net to get a hold of the basics. There is no way to write a walkthrough for your problem here as it would be quite long :o). It would also be repititive since there are millions of sites that provide such walkthroughs. Go to www.sitepoint.com, which is a web dev portal. My favortite. They have tons of usefull articles and step by step walkthroughs. From a big picture point of view what you need to do is use PHP to generate HTML dynamically and handle application logic, database interactivity. Use the MySQL database as your data store [obviously ;)]. PHP is an excellent choice as it works very well with MySQL. If this sounds like greek then don't worry too much. Head to sitepoint.com and go to the php section and start learning. It is an excellent resource. PHP.net is a good place too although you might want to go to sitepoint first. Best of luck, Arjun Quoting Troy T. Hall [EMAIL PROTECTED]: I know this sounds stupid but I'm totally lost. I've created a MySQL DB whose purpose is to track customers who have not gotten a newspaper. I've created all the necessary fields, and have managed to learn how to add/delete/modify the records in mysqlcc, but what I want is to have a predesigned form like you'd find on a webpage where you simply enter the complaints and hit submit or whatever, and it responds with the complaint ID # ( ComplaintID is an autoincrement field in the db ) Then I need to be able to print a report in a nicely labeled/readable format showing all entries made that day where the chargeable field is not List (Chargeable is an enum consisting of yes, no, list). Will someone please be kind enough to point me in the right direction. I can't seem to get my head around this concept. Troy oh, if it matters, I'm using Linux Mandrake 9.2 with the Gnome 2.0 GDM.

Core Certification
Hello everybody ! I have question regarding the MySQL core certification. Does anybody have any general insights on taking the exam ? I am studying from the manual, but I am pretty nervous about the exam as I don't know how much in depth the questions will be or even if studying from the manual alone will be sufficient. I would appreciate any thoughts or comments from anyone about the exam.Thanks ! -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
