插入外鍵SQL表

Question

與下面的表，我想回答這個問題，我不知道如何回答呢：

「顯示HoursWorked的總和爲業主的每一個類型，但不包括的服務具有少年經驗等級的員工，排除少於三名成員的任何類型的員工。「

CREATE TABLE OWNER

如果有人可以請幫助我，那太棒了！

你需要說誰是主人，插入犯規知道。

這裏我每個屬性assing到owner = 1

INSERT INTO PROPERTY VALUES('Eastlake Building', '123 Eastlake', 'Seattle', 'WA', '98119', 1); 
INSERT INTO PROPERTY VALUES('Elm St Apts', '4 East Elm', 'Lynwood', 'WA', '98223', 1); 
INSERT INTO PROPERTY VALUES('Jefferson Hill', '42 West 7th St', 'Bellevue', 'WA', '98007', 1); 
INSERT INTO PROPERTY VALUES('Lake View Apts', '1265 32nd Avenue', 'Redmond', 'WA', '98054', 1); 
INSERT INTO PROPERTY VALUES('Kodak Heights Apts', '65 32nd Avenue', 'Rochester', 'NY', '14604', 1); 
INSERT INTO PROPERTY VALUES('Private Residence', '1456 48th St', 'Bellevue', 'WA', '98007', 1); 
INSERT INTO PROPERTY VALUES('Private Residence', '1567 51st St', 'Bellevue', 'WA', '98007', 1); 
INSERT INTO PROPERTY VALUES('Private Residence', '718 151st St', 'Rochester', 'NY', '14604', 1);

列OwnerID在Property表和PropertyId和EmployeeID在Service表你製造麻煩。

以下是原因。

1）所有提到的列設置爲NOT NULL。所以這些列 總是期望每個插入的值。

2）另外，在'服務'表中，列PropertyId和EmployeeID是 複合主鍵的一部分。主鍵不允許NULL值。

3）一旦你處理點1和2，您可以通過 提列插入你的INSERT查詢，如下面

INSERT INTO PROPERTY (PropertyName,Street,City,[State],Zip) 
VALUES('Eastlake Building', '123 Eastlake', 'Seattle', 'WA', '98119'); 

INSERT INTO [SERVICE] (ServiceDate,HoursWorked) 
VALUES('2015-05-05', '4.50'); 

Answer 3

哎盧克的問題是，在插入查詢值中count與表的列數不匹配。 如果你想利用自動增量屬性寫插入查詢與列名的優勢。 和PROPERTY表中的'OwnerID'列和SERVICE表中的'EmployeeID'不能爲空，因爲您在創建表時受到限制。
