PHP SQL Inner Join or Union - mysql

Question

I want to select different fields from two different tables My users table and my address table as shown below:
my users table:
CREATE TABLE IF NOT EXISTS `users` (
`ID` int(3) NOT NULL AUTO_INCREMENT,
`AccountNumber` int(8) NOT NULL,
`FirstName` text NOT NULL,
`LastName` text NOT NULL,
`EmailAddress` varchar(200) NOT NULL,
`Password` varchar(200) NOT NULL,
PRIMARY KEY (`ID`),
UNIQUE KEY `AccountNumber` (`AccountNumber`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;
INSERT INTO `users` (`ID`, `AccountNumber`, `FirstName`, `LastName`, `EmailAddress`, `Password`) VALUES
(1, 123456, 'test', 'test', 'test#test.ac.uk', '$2y$10$/j9nTE5ugmyrWuV8VNWFxe5iHInqyaTwxt5wDaxyQwPUZTDDjqNKm');
my address table:
CREATE TABLE IF NOT EXISTS `address` (
`AddID` int(4) NOT NULL AUTO_INCREMENT,
`HouseNumber` int(11) NOT NULL,
`StreetName` varchar(200) NOT NULL,
`City` varchar(200) NOT NULL,
`Postcode` varchar(8) NOT NULL,
`AccountNumber` int(8) NOT NULL,
PRIMARY KEY (`AddID`),
KEY `AccountNumber` (`AccountNumber`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=2 ;
INSERT INTO `address` (`AddID`, `HouseNumber`, `StreetName`, `City`, `Postcode`, `AccountNumber`) VALUES
(1, 123, 'Some Road', 'someCity', 'b66', 123456);
ALTER TABLE `address`
ADD CONSTRAINT `address_ibfk_1` FOREIGN KEY (`AccountNumber`) REFERENCES `users` (`AccountNumber`);
Ive manage to use the following inner join successfully:
SELECT * FROM users INNER JOIN address ON users.AccountNumber=address.AccountNumber
However that also seems to retrieve the auto incremented ID's as well as the password field which i dont want.
I tried union but kept getting the error about different number of columns. How would i change my select statement to only retrieve the FirstName, LastName and EmailAddress from the users table and the HouseNumber, Street, City and Postcode from the address table based on the account number stored in both tables.
Any info will be appreciated
Thanks!

Answer 1

Try this u will get the result
SELECT FirstName,LastName,EmailAddress,HouseNumber,
Street, City, Postcode FROM users
INNER JOIN address ON users.AccountNumber=address.AccountNumber

Answer 2

instead of select *, just list out the columns youd like
SELECT u.FirstName,u.LastName,u.EmailAddress,a.HouseNumber,a.StreetName,a.City,a.Postcode
FROM users u
INNER JOIN address a
ON u.AccountNumber=a.AccountNumber
from there you can add a where statement if you want to limit it down to one AccountNumber:
SELECT u.FirstName,u.LastName,u.EmailAddress,a.HouseNumber,a.StreetName,a.City,a.Postcode
FROM users u
INNER JOIN address a
ON u.AccountNumber=a.AccountNumber
WHERE u.AccountNumber=12345
