[PHP-DB] join query/relational database question
I have a relational database issue that I'll simplify for the sake of this post. I have one table, called clients, that has an id and the company name. For example: id | company --- 46 Jones Inc. 54 Baker Inc. etc. I have another table called projects, that looks like this: id | company_id | status --- 1 46 Active 2 54 Inactive etc. In this case, it is relational in that company_id is the key to the clients table, for naming purposes. My question is, is it possible to do a query across two tables that could retrieve all of the information in the projects table AND have the 'company' field in the clients table come up as well. So it would be like this: id | company_id | status | company 1 46 Active Jones Inc. 2 54 Inactive Baker Inc. any help would be greatly appreciated... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Using SQL the following SELECT should be the solution: SELECT projects.id, company_id, status, company FROM projects, clients WHERE projects.company_id = clients.id You can of course add any other filter in the WHERE clause using the usual AND OR NOT operators. Of course you have to embed this command in an appropriate PhP statement, e.g. using the odbc library, and having an open connection $conn to the DB: odbc_exec($conn, 'SELECT ... '); Hope this will be enough to solve your problem.
