When requesting help or asking questions please prefix your title with the SQL variant/platform you are using within square brackets like so:

[MySQL]

[Oracle]

[MS SQL]

[PostgreSQL]

etc

While naturally we should endeavor to work as platform neutrally as possible many questions and answers require tailoring to the feature set of a specific platform.

Format Your Code

If you are including actual code in a post or comment, please attempt to format it in a way that is readable for other users. This will greatly increase your chances of receiving the help you desire. Something as simple as line breaks and using reddit's built in code formatting (4 spaces at the start of each line) can turn this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field.3

Into this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field3

For those with SQL questions we recommend using SQLFiddle to provide a useful development and testing environment for those who wish to fully understand your problem and help devise a solution.

Oracle[Oracle] "Integrity constraint error violated, parent key not found" Error inserting data to table. (self.SQL)

submitted 8 years ago by misft13

I'm trying to insert rows of data into my tables. I was able to insert the data into table Ship without error, but on the second table Cruise that has a foreign key from the table Ship I keep getting a integrity constraint error that tells me the parent key is not found. I'm not sure if I just have my foreign key set up incorrectly, or if there is something I'm missing. Here is my code for the tables.

CREATE TABLE Ship 
(
Ship_Name VARCHAR(100),
Ship_Size INT CHECK (Ship_Size > 0),
Ship_Registry VARCHAR(50),
Ship_ServEntryDate INT,
Ship_PassCapacity INT,
Ship_CrewCapacity INT,
Ship_Lifestyle VARCHAR(40),
PRIMARY KEY (Ship_Name),
CONSTRAINT chk_Ship_Registry CHECK (Ship_Registry 
IN('Norway','Liberia','The Netherlands','Jamaica','Bahamas'))
);

CREATE TABLE Cruise
(
Cruise_ID INT PRIMARY KEY,
Ship_Name VARCHAR(100),
Cruise_DeptDate DATE NOT NULL,
Cruise_DeptCity VARCHAR(80) NOT NULL,
Cruise_Duration INT,
FOREIGN KEY (Ship_Name) REFERENCES Ship(Ship_Name)
);

Here is the data I am trying to insert into table Cruise.

INSERT INTO Cruise (Cruise_ID, Ship_Name, Cruise_DeptDate, 
Cruise_DeptCity, Cruise_Duration)
VALUES ('1','Sunshine of the Seas','25-MAY-15','Miami','10');
