JOIN and INSERT

Recommended Posts

Hey guys

I am learning this Join stuff, Wicked
I got the hang of INNER JOIN for SELECT
but

I have 3 tables, and I want to insert data in all 3, without doing 3 queries

I tried this
INSERT INTO products
LEFT JOIN prices on products.id_num = prices.prod_id
LEFT JOIN stock on products.id_num = stock.prid_id
(ref_num, prod_name, suppliers, cat, sub_cat, buy_price, iva, re, total_price, sell_price, stock_level, in_stock)
VAlUES('1006', 'Cat Food', '3', 'Cat', 'Food' '8.15', '0', '0', '8.15', '10.20', '5', '5');

but I got an error on Inner the Inner Join

NOTE: this is dummy information, like a shop will buy something for 8.15 and sell it for 10.20)

All this information is coming from a form

Here is the table information for the 3 tables

CREATE TABLE IF NOT EXISTS products (
  id_num int(50) unsigned NOT NULL auto_increment,
  ref_num varchar(10) DEFAULT '0' ,
  prod_name varchar(150) DEFAULT '0' ,
  supplier varchar(50) DEFAULT '0' ,
  cat varchar(150) ,
  sub_cat varchar(150) ,
  PRIMARY KEY (id_num)
);

CREATE TABLE IF NOT EXISTS prices (
  id_num int(50) NOT NULL auto_increment,
  prod_id int(50) DEFAULT '0' ,
  buy_price double(5,2) DEFAULT '0.00' ,
  iva int(3) unsigned DEFAULT '0' ,
  re double(2,1) DEFAULT '0.0' ,
  total_price double(5,2) DEFAULT '0.00' ,
  sell_price double(5,2) DEFAULT '0.00' ,
  PRIMARY KEY (id_num)
);

CREATE TABLE IF NOT EXISTS stock (
  id_num int(50) unsigned NOT NULL auto_increment,
  prod_id int(50) unsigned DEFAULT '0' ,
  stock_level tinyint(5) DEFAULT '0' ,
  in_stock tinyint(5) DEFAULT '0' ,
  PRIMARY KEY (id_num)
);

The Connection between the 3 is
prod_id in tables Stock and prices is the same as id_num in products

Anyone who can help, Many Thanks
