I know that a CONNECT BY PRIOR patch is readily available for PostgreSQL but the PostgreSQL developers reject it exactly because it does not follow the SQL standard. I think the PostgreSQL developers are right to do so, non-standard features have caused enough trouble for application portability as it is. Jochem Point taken. I never knew about the WITH RECURSIVE syntax. Certainly, if CONNECT BY PRIOR is an Oracle only extension, then WITH RECURSIVE does sound like the better option of the two.

You could, for example, give root fewer privs when connecting externally than via localhost. Many people, myself included, eliminate [EMAIL PROTECTED] altogether, so that the root user can only connect from localhost, or replace the % with something more limiting (say [EMAIL PROTECTED]). Ask yourself which IPs should be allowed to administer mysql as root and act accordingly. How does MySQL decide which entry to use when authenticating? Eg. if you've two host entries; one '192.%' and the other '192.168.%' - and you connect from 192.168.100.12, which row gets chosen?

But what if there isn't a more exact match... i.e. choose between '192.%' or '%.168.%' Well, I can't imagine why you would put %.168.% in for host. If you did, I think 192.% would be more specific than %.168.%, but the manual is unclear on that. I suppose you could try it and see. True, I can't imagine why you would want to use %.168.% either; I was just curious. I've just tried it myself... (OK, so I was lazy before! :) - MySQL appears to prefer 192.% over %.168.% What if there are two entries - 'localhost' and '127.0.0.1' ? To mysql, those are not the same. localhost is a unix socket connection, 127.0.0.1 is a TCP/IP connection.

Re: When does using multiple databases make sense?

The reason I ask is because I am re-developing an existing database with MySQL that someone else created with another engine (DBISAM) and chose to have 5 separate databases used by one application. I've worked on a project where we had 2 databases; one was for live data, the other was used when the application switched to a training mode and so couldn't affect live data. It was a Windows app and connection was via ODBC. We had 2 ODBC sources set up to point to same server, but a different database. (Actually, it was a MS SQL Server, but the same principles apply). It was a simple matter of deciding which source to use depending on whether the app was in training mode or not.

MySQL as document storage?
Hi, (disclaimer - this thread could easily go off topic; I'm interested only in the MySQL aspects of what follows...) At work we are currently investigating ways of filing all our electronic documents. There is commercial software that will do this I know, but I was wondering whether MySQL would be suitable for this type of thing. The 'documents' could be literally any binary file. My idea would be to create a table with a blob column for the document itself, and document title, reference number, keywords, other meta-data. And a web-based front-end to search and serve documents. Although the documents could be any file, the majority would be textual documents (Word documents, PDF, etc). How would one go about indexing such data, since full text searches operate on textual columns? How to cope with columns exceeding the max packet length? Why is there a max_packet_length setting; surely this is low-level stuff that shouldn't affect query and result sizes? Is storing the actual documents in the database such a good idea anyway? Perhaps store the file in a file system somwhere and just store the filename? If anyone has experience in doing (or been dissuaded from doing) this kind of application your thoughts and comments would be appreciated. (If only to tell me don't be so stupid, it'll never work :) Thanks. -- Regards, Steve. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: MySQL as document storage?
On 7 Jan 2004, at 22:24, Rob Brahier wrote: I made an online file manager using PHP and MySQL some years ago, and am now embedding something similar into my office's database front-end. I decided to store our files in the file system rather than the database in order to keep the DB size low. A benefit of this is it takes less time to restore a backup of the database than it would if I were dealing with the extra gigabytes of embedded files (which I can restore on an individual basis). Incremental backups would certainly be smaller. The backup would spot individual files being changed, but being blobs in a table, the one (large) file in the database would have to be backed up for each change? As for indexing, a lot of the document retrieval solutions out there just go by metadata when you do a file search. Business class scanning systems offer you the option of embedding user-supplied metadata in your scanned files so adding your own keywords is an option. In my experience you are better off going by just some supplied keywords and metadata rather than the full text of a document because you end up with more relevant results. The exception to this is when you are just dying to know how many documents contain the word pie. If you find that this is the case then you obviously have the free time needed to build some extra indexes... ;) I think you're right.

Using MySQL as an RCS repository
Hi, I'm not sure if that subject made any sense!? What I'm looking to do is take an existing product we have (a software defect tracker) that uses flat files to store defect entries. Modifications to each defect are recorded as diffs using the perl module RCSLite (like your standard RCS, but all in perl). Because this is all currently in files, in our performance tests we've done we're (obviously!) seeing slow downs when processing a database with large numbers of entries. And that's not just the equivalent of full-text searches. We have sketched out a few database designs that can replace it, but all would involve losing the revision history of each entry (there is some reluctance to do that!). During it's lifetime, each 'defect' in the database gets modified, probably, on average 3 or 4 times, at most, maybe 10. Modifications are usually additional text (not allowed to modify old text), state changes (like open - fixed - ready for test, etc), and who the defect is assigned to. As I said, we have database designs that can replace *most* of what we have already, but I'm interested in the RCS side of things, and whether anybody has any experience of doing this sort of thing (RCS) or some tips to share. Thanks very much. -- Regards, Steve -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
