Question

drop database if exists RentaHouse; 
create database RentaHouse; 

use RentaHouse; 

create table Staff(
staffNo char(5) not null primary key, 
fName varchar(15), 
lName varchar(15), 
position varchar(15), 
dob date, 
salary decimal (7,2) unsigned 
); 

create table PropertyForRent(
propertyNo char(5) primary key, 
street varchar(35) not null, 
city varchar(15) not null, 
pcode varchar(10), 
type varchar(20) not null, 
rooms tinyint unsigned not null, 
rent decimal (6,2) unsigned, 
staffNo char(5) 
); 

ALTER TABLE PropertyForRent 
    ADD CONSTRAINT whatever foreign key(staffNo) references Staff (staffNo) ON DELETE CASCADE ON UPDATE CASCADE; 


insert into staff values 
('s1234','Mary','Jones', 'Sales', '1975-12-22',45000), 
('s1834','Pat','Roche', 'IT', '1972-09-13',42000), 
('s1998','Michael','Brown', 'Sales', '1980-12-09',43500); 

insert into propertyForRent values 
('p3296','21 Ash Street','Tramore','WD34-543', 'Bungalow',4,1200,'s1234'), 
('p3299','William Street','Dungarvan','WD99-088', 'Terrace',3,1050,'s1234'), 
('p3344','9 Mary Street','New Ross','WX99-044', 'Terrace',3,800,'s1998'), 
('p3356','21 Mary Street','New Ross','WX99-076', '2 Storey',4,1100,null); 



/*doesn't work!*/ 
CREATE VIEW anyView AS 
    select * from Staff; 

/*work!*/ 
select * from Staff; 

/*work!*/ 
select street, city, type, rent, concat(fName, lName) as 'Name' from 
PropertyForRent join Staff on PropertyForRent.staffNo = Staff.staffNo where city = 'New Ross' order by rent; 

/*doesn't work!*/ 
CREATE VIEW myView AS 
select street, city, type, rent, concat(fName, lName) as 'Name' from 
PropertyForRent join Staff on PropertyForRent.staffNo = Staff.staffNo where city = 'New Ross' order by rent; 

alle Ansichten geben kein Ergebnis zurück! Ich verwende "sakila" als Standardschema mit MySQL Workbench 6.3.8.

Ich habe 2 Tage online nach einer Lösung suchen, aber ich denke, es ist Zeit zu fragen, wer Expertise haben bitte.

P. Sichten funktionieren nicht für jede Datenbank, die ich nicht nur für dieses Schema erstelle!

Answer 1

CREATE VIEW anyView1 AS select * from Staff; 

then fetch data 
select * from anyView1; 


CREATE VIEW myViewss AS 
select street, city, type, rent, concat(fName, lName) as 'Name' from 
PropertyForRent join Staff on PropertyForRent.staffNo = Staff.staffNo   where city = 'New Ross' order by rent; 


select * from myViewss;
