SQL Error: ORA-02291: integrity constraint

I am creating a database that is trying to access values from a foreign key. I have created two following tables

    ComponentID varchar2(9) PRIMARY KEY
    , TypeID varchar2(9) REFERENCES TypeComponent(TypeComponentID)

INSERT INTO Component VALUES(192359823,785404309)
INSERT INTO Component VALUES(192359347,785404574)
INSERT INTO Component VALUES(192359467,785404769)
INSERT INTO Component VALUES(192359845,785404867)
INSERT INTO Component VALUES(192359303,785404201)
INSERT INTO Component VALUES(192359942,785404675)

CREATE TABLE TypeComponent (
    TypeComponentID varchar2(9) PRIMARY KEY
    , Type_Description varchar2(30) CONSTRAINT Type_Description 
        CHECK(Type_Description IN('Strap', 'Buckle', 'Stud')) NOT NULL

INSERT INTO TypeComponent VALUES(785404309, 'Strap')
INSERT INTO TypeComponent VALUES(785404574, 'Stud')
INSERT INTO TypeComponent VALUES(785404769, 'Buckle')
INSERT INTO TypeComponent VALUES(785404867, 'Strap')
INSERT INTO TypeComponent VALUES(785404201, 'Buckle')
INSERT INTO TypeComponent VALUES(785404675, 'Stud')

These are the two tables. Component and TypeComponent. Component is the parent entity to TypeComponent, and I am trying to run the following INSERT statement:

INSERT INTO Component VALUES(192359823,785404309)

but it is giving me the error

This is the session that I have so far in Oracle SQL dev


Try inserting in your TypeComponent table first, then insert into your Component table.

According to the error:

ORA-02291:    integrity constraint (string.string) violated - parent key not found Cause:            A foreign key value has no matching primary key value. Action:            Delete the foreign key or add a matching primary key.

This means that there is no matching key in your referenced table.
