Re: [PHP] select * from...
Sounds like you want to do an inner(?) join on the two tables. This will show you where you have matches between the two tables but also show you the items that don't match (no special instructions). If I understand right, you have an order_id in both orders and special_orders_instructions right? You can just link on that without needed to add any special columns. Try something like this: SELECT o.order_id, o.otherordercolumn, soi.order_id,j soi.otherinstructioncolumns FROM orders AS o LEFT JOIN special_orders_instructions AS soi ON o.order_id = soi.order_id Then in PHP just check to see if soi.order_id is blank or not. If it is, there's no special orders to be found. If it's not blank, then check out the SOI variables. Hope that helped a little. Forgive any typos... wanted to respond quick so I could go home. :) -TG = = = Original message = = = Hi to all, It's more mysql question than php, but I like you more than mysql guys! :) Let's say I have a table called orders and other table called special_orders_instructions. Logically, one column in orders table should be link to special_order_instructions (foreign key ?) and if that one is checked go and grab special instructions after order_id. But, since orders table doesn't have such a column (and I CANNOT add it - long story...) I have to check for every order does that order_id exists in special_order_instructions table. And, if yes - print. Table special_order_instructions has about 25 columns and I have to show EVERY ONE. Means, have to use select * from special_order_instructions... But, just to check does such an order have any special instruction $query = mysql_query(select * from special_order_instructions...); is bad idea. It would be more correct $query = mysql_query(select spec_inst_id from special_order_instructions...); and then if (mysql_num_rows($query) 0) // Show instructions Does this make a sense: $query = mysql_query(select spec_inst_id from special_order_instructions...); if (mysql_num_rows($query) 0) $query = mysql_query(select * from special_order_instructions...); while( ... ) // show instructions here...

Re: [PHP] select from db
I think I misread your script.
I took the line
print table cellspacing=\0\ cellpadding=\5\ border=\1\;
to be part of the while loop, meaning there would be two statements. I'm
not accustomed to seeing scripts that use functions without brackets, even
when their not required.
Sorry for the confusion.

Re: [PHP] Select from 24 tables
This isn't always desirable, or even possible. I once designed a database to hold characteristics for a series of 70 different tests. There were about 50 different characteristics used in various combinations for each test. Each characteristic could be one of many values. So the characteristics tables all looked like this: id, name, value And the test tables looked like this: id, name, value And the mapping of characteristics to test looked like this: test_id, characteristic_id This is actually a gross oversimplification, but you get the idea. Displaying test results typically required joining 30-40 tables together, but since each characteristic table was small (10-15 entries), performance was acceptable. So do as John Nichel first suggested, and do this: select c1.id as characteristic1_id, c2.id as characteristic2_id from characteristic1 c1, characteristic2 c2 etc. cheers, Travis John W.

In my experience, the best way to deliver a quality application is to start with a fully-normalized database schema, then de-normalize it slightly here and there if performance is really a problem. But I've rarely had to do that. In most cases, an upgrade to a faster server with more memory solves the problem more quickly and cheaply than an application re-write would. On the other hand, I've been called in many times to deal with application problems that arise from using mashed-together schemas such as the one you propose. John W.

Hi Michal, Getting back to the original posting, I'm basically saying that I don't think it's a good idea to structure or restructure a database for the sake of simplifying a few SQL statements. Especially if the data being joined is in separate tables for a good reason.

Re: [PHP] SELECT * FROM
In your query add ORDER BY field name like date or ID DESC.
That way it will put them in descending order and I do believe that is what

RE: [PHP] SELECT * FROM
Couple of other tips for you. 1. SELECT * is bad unless you really need every field. If you don't, specify which ones you want - the query will perform better. $s = SELECT * FROM News; // bad $s = SELECT NewsHeadline, NewsTeaser FROM News; // better 2. You appear to be connecting to your database (a) as root and (b) without a password (although you may have modified the code, so I'm not sure). This is even worse than SELECT * :-) Cheers Jon -Original Message- From: Tarrant Costelloe [mailto:[EMAIL PROTECTED]] Sent: 29 August 2001 15:55 To: '[EMAIL PROTECTED]' Subject: [PHP] SELECT * FROM Hello all, I have a designing a website of which people can submit news to, this works fine.

Re: [PHP] select * from nmensagem m, nusuario...
select * from nmensagem m, nusuario u, nprefuser p where m.cdpreferencia=p.cdpreferencia and p.flag=1; With "m.cdpreferencia=p.cdpreferencia" I should get just the values there exists on m.preferencia and p.cdpreferencia? No, because you have a record for every single nusario, since you don't restrict any relation between u and m, nor u and p -- Visit the Zend Store at http://www.zend.com/store/ Wanna help me out?
