[PHP-DB] help me JOIN 3 tables.
I have this SQL SELECT e1.*, l1.* FROM e1 INNER JOIN l1 WHERE e1.entre_active = 'Y' AND l1.entreID = e1.entre_id The above query works but i want to add the one below SELECT SUM(a1.adp_amount) as amount FROM a1 WHERE a1.adp_loanID = e1.loanID; the last part of the query is to SUM the part payment made on table 'l1' and return total raised with the first query. the whole idea is three tables, (business, loan, raised), loan referenced ID from business, raised referenced ID from loan. loan maybe $300 and it can be raised over time till completed, so all the amount raised + the loanId will be stored inside the raised table. Thank you
Re: [PHP-DB] help me JOIN 3 tables.
Hi Joseph, With the sum() aggregate function you'll need to use a GROUP BY clause and specify which fields you want from e1 and l1. Something like this: SELECT e1.field1, e1.field2, l1.field3, SUM(a1.adp_amount) as amount FROM a1 inner join e1 on (a1.loanID = a1.adp_loanID) inner join l1 on (l1.entreID = e1.entre_ID) WHERE e1.entre_active = 'Y' hth, Yves - Original Message - From: Abah Joseph joefa...@gmail.com To: php-db@lists.php.net Sent: Tuesday, January 13, 2009 6:46 AM Subject: [PHP-DB] help me JOIN 3 tables.

not really sure how to do this, other than planning for as much as you can in your original tables, then have a spare table with four columns - Row_ID, Characteristic_Name, Characteristic_Value, and Product_Refer_ID. so then if you get a new characteristic (eg colour) then you could have values 1, colour, blue, 4(the product with this characteristic). then the next line might be 2,colour,green,8 then 2,density,45kg/m3,8 etc. not sure this is the best way, but the only way i can think of to have various additional characteristics for some products. hope it helps??

RE: [PHP-DB] help me on projecting some tables
Carlo, Your question is the reason for the invention of the relational database. Please do NOT add columns for planned expansion. How many extra columns would you need? 4? 10? 25? 100? Such a schema is wasteful of storage. There are several ways to go about this. For example: CREATE TABLE products( product_id int auto_increment primary key, description char(50) default , quantity int not null, unit enum (each,lb,ounce,gallon,quart), price decimal(5,2) not null ) CREATE TABLE traits( characteristic char(25) default , product_id int, description char(25) ) In the above example, when you wanted to add a characteristic for a particular product, you simply add a record into traits and set traits.product_id equal to products.product_id. This will make it REAL EASY doing joins on this combo as well. For example: INSERT INTO products VALUES(NULL, Coca Cola,1,ounce,0.39); INSERT INTO traits VALUES(Liquid,LAST_INSERT_ID(),Seltzer-based); INSERT INTO traits VALUES(Added Chemicals,LAST_INSERT_ID(),Sugar); INSERT INTO traits VALUES(Added Chemicals,LAST_INSERT_ID(),Brown Dye); INSERT INTO traits VALUES(Added Chemicals,LAST_INSERT_ID(),Caramel coloring); To get all the characteristics for a given product: SELECT * FROM products LEFT JOIN traits USING(product_id) ORDER BY char_1.characteristic In another example, if multiple products will come in multiple styles, you would create a table called STYLES and insert a record for each style available: CREATE TABLE styles( color char(10) default , product_id int, ) INSERT INTO products VALUES(NULL,Bread,1,each,1.49); INSERT INTO styles VALUES( White,LAST_INSERT_ID() ); INSERT INTO styles VALUES( Black,LAST_INSERT_ID() ); INSERT INTO styles VALUES( Wheat,LAST_INSERT_ID() ); INSERT INTO styles VALUES( Hawaiian,LAST_INSERT_ID() ); -Original Message- From: matt stewart [mailto:[EMAIL PROTECTED]] Sent: Friday, November 16, 2001 5:55 AM To: 'Carlo Loiudice'; PHP DB Subject: RE: [PHP-DB] help me on projecting some tables not really sure how to do this, other than planning for as much as you can in your original tables, then have a spare table with four columns - Row_ID, Characteristic_Name, Characteristic_Value, and Product_Refer_ID. so then if you get a new characteristic (eg colour) then you could have values 1, colour, blue, 4(the product with this characteristic). then the next line might be 2,colour,green,8 then 2,density,45kg/m3,8 etc. not sure this is the best way, but the only way i can think of to have various additional characteristics for some products. hope it helps??

RE: [PHP-DB] help me on projecting some tables
A couple of questions: INSERT INTO traits VALUES(Added Chemicals,LAST_INSERT_ID(),Sugar); 1. Will LAST_INSERT_ID() work reliably in a multi-user environment? What happens if you're in the middle of inserting a dozen records and someone else inserts a record? Does MySQL keep the LAST_INSERT_ID()s separate (since the web application will see both transactions as being done by the same user)? 2. Is there any benefit to having a 3rd table to keep track of characteristics ? I guess that quesiton is best answered by examining the business needs. If the characteristics are few and don't change often, it seems to me that you'd want a 3rd table to keep them. That way, the spelling is similar, etc, and therefore you can do (accurate) queries based on the characteristics (if the need ever came up) TIM -Whenever you hear a man speak of his love for his country, it is a sure sign he expects to be paid for it. -Original Message- From: Rick Emery [mailto:[EMAIL PROTECTED]] CREATE TABLE products( product_id int auto_increment primary key, description char(50) default , quantity int not null, unit enum (each,lb,ounce,gallon,quart), price decimal(5,2) not null ) CREATE TABLE traits( characteristic char(25) default , product_id int, description char(25) ) In the above example, when you wanted to add a characteristic for a particular product, you simply add a record into traits and set traits.product_id equal to products.product_id.

1. Don't know answer to question. However, surround the INSERTs with LOCK/UNLOCK Table commands to prevent the problem you desecribe.

[PHP-DB] Help Me!
Hi Netlanders I have just undertaken a web site construction project. It is a devshed like site that serves articles on various topics. I am using LAMP - Linux/Apache/MySQL/PHP 4. I have a table that contains info about each article. I think I have three options...(or do I have more that I dont know of?!) 1. Store the article body in the database as a LONGTEXT or BLOB 2. Separate plain text file 3. Separate HTML formatted file No matter whether the file is in the database or as a separate file, should it be formatted? If it is plain text, how do I make distinctions between bold text and normal text? (Will fread() using PHP give me '\n' and other such characters too?) If it is HTML formatted, I would loose some control over the look and I would have to copy and paste the plain text article and make it a HTML file. What should I do? I know I have already asked this question and got some answers. But, when I proceeded with the project, I kept comming back to this one point. A long answer might help. Looking forward to your help.
