Hi guys I would like to have a SQL query to couple five tables to accomplish my need. This is a search page and the user will be searching using the don_id Presently I am using a simple equi join which works fine if all the five tables contain data for user_id But if any of the tables have no value for that particular don_id, it is obvious that nothing is being displayed.
I think that a left join will be better but can't get one to display results from all the five tables And the don_id is not unique in the claim table. So claim table can have same don_id any number of times, I would like to display all the claim details for that particular don_id with unique values from other tables also. Here are the tables 1.CREATE TABLE don(don_id char(20) primary key , buy_date date not null) ; 2.CREATE TABLE enduser( user_id char(20) primary key, user_name varchar(50) not null, user_addr_str varchar(150), don_id char(20) unique not null, pro_pd char(20) unique not null, maker varchar(150), cpu varchar(150)) ; 3.CREATE TABLE usersale(user_sale_id varchar(20) primary key, user_id varchar(20) not null, don_id varchar(20) unique not null, pro_pd varchar(16) unique not null) ; 4.CREATE TABLE ssale(shit_sale_id varchar(20) primary key, s_id varchar(20) not null, don_id varchar(20) unique not null , pro_pd varchar(16) unique not null); 5.CREATE TABLE claim(claim_id int auto_increment primary key, user_id varchar(20) not null, don_id varchar(20) not null, pro_pd varchar(20) not null, claim_date date not null, claim_det text not null) ; Note: Also I may include more tables in the future.I am writing the sql query during the runtime by getting field values from the user input through check boxes and so I would prefer to have a single query to do this. Hope that some of you can help me and thanks in advance Kayamboo suresh --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
