Re: Hybrid Environment
Hey John, It very much depends on what your users needs are. In my experience, there's an opensource alternative that integrates well with proprietary systems if needed for everything i can think off. I've been working solely on Linux for more than 3 years now. My laptop came with Vista pre-installed and the reason it's still there, is that I haven't gotten around to wiping it clean. I suggest you make a list of all the software you need in your company and then go about finding opensource alternatives. They'll be there, you just have to ask yourself if they fit your needs. Software used here: Eclipse for development (all languages), Firefox/Thunderbird goes without saying, OpenOffice.org for word processing and spreadsheets. The only problem I can think off, is the compatibility between some Office versioned documents and OpenOffice, but hey, you don't even get that compatibility between different versions of Office and you certainly can't beat the price of OpenOffice.org :p In conclusion, from a developers point of view, you can't beat Linux. It's safe, it's easy and most of all, it's considerably faster. regards, boro john_sm schreef: Hey Guys, I am still in a thinking stage and will like to learn from your experience, and was wondering if any of you folks have a hybrid environment i.e. Linux and Proprietary systems and what kind of issues do you run into.

Re: error once backing up database
You cannot execute the grant command because you don't have permission to do so. The GRANT command allows you to set permissions on databases and tables, thereby giving access to possibly sensitive data. It is in no way a serious restriction, it is a very important security feature. If you don't have the grant permission and need it, ask your database administrator to set up rights. Don't assume that what may be easier for you in other software environments, is the better solution. In this case, it clearly is not. regards, boro Banyan He schreef: Yes, the server shows me that.

Re: database structure
Hey there again, I suggest you look up a tutorial about database normalisation. Good ones are often hard to find. In general, you give all tables that contain data you will be referencing in other tables a numeric id (INT(11) UNSIGNED) as primary key, and you use that key as the constraint. Your table `locations` will be referenced in your table `tags` as such: FOREIGN KEY (`location`) REFERENCES `locations`(`id`) ON UPDATE CASCADE ON DELETE SET NULL Search the mysql manual for those update/delete options to see what they do and adjust them to your needs. The ones given are the ones I in most situations. HTH, boro Hiep Nguyen schreef: Now, if I have a location table with id, name, address, phone, fax, etc... Should I put id or name into the tag table? If id used, then how do i look up the name, address, phone, fax, etc... when I do a select on tag table? Thank you for all your helps T.

Re: database structure
Or:
Tag
ShapeDimension (type enum('height', 'thickness', etc), value VARCHAR()
or INT())
TagsShapeDimensions (FOREIGN KeY TAG, FOREIGN KEY ShapeDimension)
1 less table

Rajesh Mehrotra schreef:
Hi,
You can do this in four tables:
1. Tag
2. Shape (with an additional field, let us call it X, describing how
many data elements each shape has)
3. ShapeElements : one record describing each data element (length,
width etc.) for each shape. Record count for each shape: X
4. Data Table : X number of records for each TagID. References
ShapeElements.
The number of table will remain fixed at four, no matter how many shapes
you have. And your SQL statements will be generic, most of the times,
regardless of the shape.

Subject: database structure
Hi all,
i'm seeking for help/suggestion on how to create relationship for this
scenario:
I have one table (tag) with the following fields:
tagid, location, weight, grade, heat, shape, diameter, length, width,
height, ... (and many other fields)
what i want to do is move the shape field into a different table,
however,
each shape will have different dimensions
for sample:
rod bar has diamter and length, but square/flat bar has width, height
(thickness), and length. wire has only diameter.
but i also don't want to create a huge table to hold all the possible
fields in all shapes, so i'm thinking create a table per shape:
round table (diameter, length)
square table (width, height, length)
i-beam table (flange height, flange thickness, web thickness)
angle table (leg1, leg2, thickness)
...
and so on.
in turn, i have 2 tables: tag, shape + as many table as there are shapes
my question is: is there a better to do this? how do i query with this
structure? i'm a bit confuse on how to manipulate data if each shape
have
diffent fields???
Thank you for all your help (sorry for a long email)
T. Hiep

Re: Select Last X rows
Rich schreef: Hi folks. Just wanting to know the best way to grab the last 10 rows from a table. Looking twice to the db to see how many records there are will be outdated by the time the SELECT is done, so it's moot. This is a fast moving db with records coming and going. Instead of having an offset in LIMIT, is there a way to ask for the last 10 rows directly? Cheers Rich in Toronto Hey, Why is ORDER BY in combination with LIMIT not a valid solution to your problem ?
