RE: Making MySQL DB Remotely Accessible
Try this program. Go to http://www.artronic.hr/mysql/index.htm and get mysqladmin. Its a windows client to manage mysql databases. You then can put in the ip address of the computer you want to connect to that is running a mysql database. So you would put your win2000 server ip. Then put in a user and a password. Leave the port at 3306 unless you changed it. Probably need to use root user to get in the first time. Hope this helps some.

RE: Hom many columns is too many?
Without knowing more detail about the data and the requirements of that data its hard to say how the database structure should be. To say I am right over you and you are right over me is pointless. Its very dependant on the data. I agree you can have a entity with 75+ attributes and its not going to be demoralized. I have worked with databases with over 200 attributes that were fully normalized. There is more then one way to solve any problem. 50 of the ways are great 50 of them suck but all will get the job done. That is the beauty of database design and programming, I think. -Original Message- From: ryc [mailto:[EMAIL PROTECTED]] Sent: Friday, May 11, 2001 4:09 PM To: [EMAIL PROTECTED] Subject: Re: Hom many columns is too many? Just because one table has many columns does not mean it is not normalized. The original message stated that there is all kinds of different information about a contact from their first/last name to the high school they graduated from. Given enough information about a person it would be easy to fill 75 columns of DIFFERNT data. Sure there may be a column to store phone numbers... but that doesnt mean that in order to add another phone number for a particular contact that you would insert a whole new row. Either a) you decide not to keep more than one phone number per contact, and use an update to change the phone number for that contact or b) create a phone number table so you can create a one to many relationship (one row in the contact table can have multiple rows in the phone number table). In case b yes some information is taken out of the contact table and put into another table, however that is just one column. For things like mothers maden name and other unique and SINGLE data elements putting that data in the contact table does not denormalize the table. The only situation in which I can think to create a seperate table with this sort of information is a) one contact may have many of column y or b) a majority of the contacts dont have information for column y, so you create a seperate table for column y to store the few rows you do have information for, so that your contact table doesnt have a bunch of empty fields. Hope this helps. ryan Well with tables not normalized you will more then likely at some point in get redundant data at some point. For instance I enter Joe smith with phone of 123-123-1222 then Joe Smith buys a new home keeps the other home and now has two active phone number with on table you would have to reenter information already in the database on Joe Smith unless you keep adding more columns to accommodate each new phone number(this would be very poor database design). Its basic normalizing of tables that will keep this from happening. Its is very dependent on the nature of the data on whether you need to break that table up or not. I would find it very hard to believe that all the information needed for customer/contact data from there name all the way to where they went to high school could be stored in one table logically or more importantly efficiently. -Original Message- From: ryc [mailto:[EMAIL PROTECTED]] Sent: Friday, May 11, 2001 11:58 AM To: 'Richard Reina'; [EMAIL PROTECTED] Subject: Re: Hom many columns is too many?

However 75 does seem like it is a very obscene amount for one table, so you may want to consider creating one table that stores the contacts primary information (name, address, phone #, business name, ect... ) that is imparative to working with the contact, and then have another table that contains more detailed background information. This way if you need the information from the second table you can left join it, and if you dont need it you dont have to. Or another scheme is only insert detailed data for the contacts you have that information on, and leave the rest blank (in this case you wont be able to use left join because if the column you join on is missing from the details table the query will return empty, even though the contact is in the primary table). Either way there are trade offs, decide what is best based on how much detail information you have from the contacts, and how you want to lay out your code. Hope that helps, ryan With relational database design you can more then likely break that 75 column table down into many different tables.

RE: Having success with 20 million rows
I take that back the word not the best shouldnt be used. I should of said in a perfect world we shouldnt have to add columns. -Original Message- From: Robert Henkel [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 09, 2001 2:56 PM To: 'Joshua J.

RE: database recovery (errcode 13)?
When you say you moved the data base I'm assumeing you are meaning you reinstalled MySQL then moved the db files over to the new install? Each data base goes into its own directory. So the database files for the database named thedb would be in a subdirectory called thedb of the directory data . I am talking from a windows environment maybe its different on Linux. root=mysql sub1=data sub2=thedb---database files for thedb go here -Original Message- From: Kay Aleksic [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 09, 2001 2:10 PM To: MySQL List (E-mail) Subject: database recovery (errcode 13)? Hi list, I am dealing with my first MySQL server/db, and I ran into some trouble. The server where the db was located got hacked and I had to reinstall the whole thing. The old HD is preserved as was and the server got a new HD. I moved the old db to the new disk and when I try to access it, I get the following error: mysql use thedb; Can't read dir of './thedb/' (Errcode: 13) Database changed mysql show tables; ERROR 12: Can't read dir of './thedb/' (Errcode: 13) mysql (RedHat 6.2, MySQL 2.23.37) How can I recover or fix it? Thanks in advance for any help. K.
