SQL query join condition - mysql

Question

I have a database of the following relations:
Bar(Name, Address, Licence)
Beer(Name,Manufacture)
Drinker(Name,Address)
Frequents(DrinkerName,BarName)
Likes(DrinkerName,BeerName)
Sells(BarName,BeerName,Amount)
Serves(BarName,BeerName)
The Sample DDL Statements:
CREATE TABLE `Bar` (
`Name` varchar(255) NOT NULL,
`Address` varchar(255) DEFAULT NULL,
`Licence` varchar(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `Bar` (`Name`, `Address`, `Licence`) VALUES
('Deluxe', 'Luxvagen 2', 'Yes'),
('Grace', 'Gracevagen 2', 'Yes'),
('KrogBar', 'Barvagen 2', 'Yes');
CREATE TABLE `Beer` (
`Name` varchar(255) NOT NULL,
`Manufacture` varchar(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `Beer` (`Name`, `Manufacture`) VALUES
('Carlsberg', 'Coppers'),
('Heiniken', 'Spendrups'),
('Miller', 'DaMill');
CREATE TABLE `Boor` (

) ENGINE=InnoDB DEFAULT CHARSET=utf8;
CREATE TABLE `Drinker` (

`Address` varchar(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `Drinker` (`Name`, `Address`) VALUES
('Alex', 'Överbar 2'),
('Bam', 'Påbar 2'),
('Emil', 'Mittibar 2'),
('Max', 'Ibar 2'),
('Petra', 'Förebar 2'),
('Rebecca', 'Efterbar 2'),
('Sam', 'Underbar 2');
CREATE TABLE `Frequents` (
`DrinkerName` varchar(255) NOT NULL DEFAULT '',
`BarName` varchar(255) NOT NULL DEFAULT ''
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `Frequents` (`DrinkerName`, `BarName`) VALUES
('Emil', 'Deluxe'),
('Max', 'Deluxe'),
('Rebecca', 'Deluxe'),
('Alex', 'Grace'),
('Petra', 'Grace'),
('Bam', 'KrogBar'),
('Sam', 'KrogBar');
CREATE TABLE `Likes` (
`DrinkerName` varchar(255) NOT NULL DEFAULT '',
`BeerName` varchar(255) NOT NULL DEFAULT ''
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `Likes` (`DrinkerName`, `BeerName`) VALUES
('Bam', 'Carlsberg'),
('Emil', 'Carlsberg'),
('Rebecca', 'Carlsberg'),
('Emil', 'Heiniken'),
('Max', 'Heiniken'),

('Sam', 'Heiniken'),
('Alex', 'Miller');
CREATE TABLE `Sells` (
`BarName` varchar(100) DEFAULT NULL,
`BeerName` varchar(100) DEFAULT NULL,
`Amount` int(11) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `Sells` (`BarName`, `BeerName`, `Amount`) VALUES
('KrogBar', 'Miller', 3),
('KrogBar', 'Carlsberg', 2),
('KrogBar', 'Heiniken', 1),
('Deluxe', 'Heiniken', 1);
CREATE TABLE `Serves` (
`BarName` varchar(255) NOT NULL DEFAULT '',
`BeerName` varchar(255) NOT NULL DEFAULT ''
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `Serves` (`BarName`, `BeerName`) VALUES
('Grace', 'Carlsberg'),
('KrogBar', 'Carlsberg'),
('Deluxe', 'Heiniken'),
('Grace', 'Heiniken'),
('KrogBar', 'Heiniken'),
('KrogBar', 'Miller');
I want to find drinkers that frequent only bars that serve beer that they like (the assumption is that each drinker frequents at least one bar).
How can I construct such a query? I know that I have to use Joins and Sub-queries, I am not new to either of them but all my implementations have not yielded the correct results.

Answer 1

Is this what you looking for;
Select DISTINCT bar.Name,bar.Address,frequents.DrinkerName, likes.BeerName
From
Bar
Join frequents on bar.Name = frequents.BarName
join sells on bar.name = sells.BarName
join likes on frequents.DrinkerName = likes.DrinkerName
