Error ORA-02291: Integrity Constraint - 1:1 instead of 1:M? - sql

Question

I see that the parent key isn't found. In my case, both FK_PLAYERTEAM and FK_PLAYERPOSITION. I noticed that everywhere I see this error, it's an order of operations mistake. The values for position, or team id were not entered in before entering or referencing those values in the Player table. It seems in my case, that once there are 14 players entered, the same amount of teams there are, that I can no longer enter any more players.
So do I have a one to one rather than a one a to many relationship here? Please review my work! I'm new, doing this for my summer class project.

Answer 1

You are applying an incorrect foreign key constraint, try this:
CREATE TABLE TEAM (
ID int NOT NULL PRIMARY KEY,
NAME varchar2(255) DEFAULT 'FREE AGENT',
SHORT_NAME varchar2(3) NOT NULL,
COACH_NAME varchar2(255) NULL,
CITY_ID int NULL,
CONSTRAINT FK_TEAMCITY FOREIGN KEY (CITY_ID) REFERENCES CITY(ID)
);
