I am stuck on the last constraint. Every time I get a message saying "JAN" invalid identifier.
Can anybody please identify the mistake and correct it for me?

So this is my code for a homework
CREATE TABLE workorders
(
wo# NUMBER(5) PRIMARY KEY,
proj# VARCHAR(10) NOT NULL FOREIGN KEY REFERENCES project(proj#),
wo_desc VARCHAR(30) NOT NULL UNIQUE,
wo_assigned VARCHAR(30),
wo_hours NUMBER(5) NOT NULL CHECK(wo_hours>0),
wo_start DATE,
wo_due DATE,
wo_complete CHAR(1),
CONSTRAINT workorders_wo_complete_chk CHECK(wo_complete in('Y','N'))
);
I could not figure out why oracle apex won't let me create this table, it says
ORA-00907: missing right parenthesis
But I double-checked so many times and I think I do have all the parenthesis? What did I do wrong here?
Thanks in advance
I just want to create this table under these constreaints but I could find any errors that I know of.
Oracle's error messages are often not particularly helpful, and the best thing to do is to go through your code, line by line, commenting out each line until you isolate the problem.
In this case the offending line is
proj# VARCHAR(10) NOT NULL FOREIGN KEY REFERENCES project(proj#),
and the problem is that you don't use the words FOREIGN KEY to define a foreign key - you just need to specify what it references. So this should be
proj# VARCHAR(10) NOT NULL REFERENCES project(proj#),
and then you'll be fine.
db<>fiddle here
When defining an inline constraint, the FOREIGN KEY terms are not used:
proj# VARCHAR2(10) NOT NULL
REFERENCES project(proj#)
Note: Oracle uses VARCHAR2 and VARCHAR is an alias to VARCHAR2 and it is considered best-practice to use VARCHAR2 throughout.
However, those keywords are required when you define an out-of-line foreign key (but then you would be missing a comma and the column identifier):
proj# NOT NULL,
FOREIGN KEY (proj#) REFERENCES project (proj#)
Note: If you are using a foreign key constraint then you do not need to define the data type and Oracle will implicitly use the data type of the column being referenced.
The complete code using (named) inline constraints throughout would be:
CREATE TABLE workorders
(
wo# NUMBER(5)
CONSTRAINT workorders__wo#__pk PRIMARY KEY,
proj# -- Note: do not need the data type as the FK will define it.
NOT NULL
CONSTRAINT workorders__proj#__fk REFERENCES project(proj#),
wo_desc VARCHAR2(30)
NOT NULL
CONSTRAINT workorders__wo_desc__u UNIQUE,
wo_assigned VARCHAR2(30),
wo_hours NUMBER(5)
NOT NULL
CONSTRAINT workorders__wo_hours__chk CHECK(wo_hours>0),
wo_start DATE,
wo_due DATE,
wo_complete CHAR(1)
CONSTRAINT workorders_wo_complete_chk CHECK(wo_complete in('Y','N'))
);
and using (named) out-of-line constraints throughout:
CREATE TABLE workorders
(
wo# NUMBER(5),
proj# -- Note: do not need the data type as the FK will define it.
NOT NULL,
wo_desc VARCHAR2(30)
NOT NULL,
wo_assigned VARCHAR2(30),
wo_hours NUMBER(5)
NOT NULL,
wo_start DATE,
wo_due DATE,
wo_complete CHAR(1),
CONSTRAINT workorders__wo#__pk PRIMARY KEY(wo#),
CONSTRAINT workorders__proj#__fk FOREIGN KEY (proj#) REFERENCES project(proj#),
CONSTRAINT workorders__wo_desc__u UNIQUE(wo_desc),
CONSTRAINT workorders_wo_complete_chk CHECK(wo_complete in('Y','N')),
CONSTRAINT workorders__wo_hours__chk CHECK(wo_hours>0)
);

I have stared at this until my eyeballs bleed, where am I missing a parenthesis? It does also say
Error starting at line: 1 in command-".
The cause and action section of the error report is blank.

This just because you missed column name while declaring primary key. There is another problem: constraint name for both fourth and fifth columns are same. I have changed that too.
And there is no need to declare CONSTRAINT EVENTNO_NOTNULL NOT NULL since you are declaring it as primary key.
CREATE TABLE EVENTREQUEST(

I'm trying to make two tables execute but I keep getting errors on them. Transaction table says it can't execute without the other being created and then I try to create the broker table and it says missing right parenthesis
SQL Error: ORA-00907: missing right parenthesis
but I checked my code and it looks well. Would any of you know what is the problem? thanks to all who comment!

It's this line
Last_Name Varchar2(3O)
That's not 30, it is 3O, as in the letter O after the number three.
One way to debug such error statements is to remove one column at a time, run the statement, and repeat the process until you don't encounter the error any more. In this case, I deleted this specific line and it worked fine. That's when I noticed the O instead of 0 in the editor.
I only have this error now.. I cant seem to see where it is too long (ERROR at bottom of page)

Do something below. In your query, a comma is missing when you are declaring discount column in bill_item table.
CREATE TABLE Bill_Item3
(
Bill_Number NUMBER(6,0) CONSTRAINT NN_BillItem_BillNumber NOT NULL,
Menu_Item_Number NUMBER(5,0) CONSTRAINT NN_BillItem_MenuItemNumber NOT NULL,

CONSTRAINT CK_BillItem_SellingPrice CHECK (Selling_Price >= 0 ),
CONSTRAINT PK_Bill_MenuItem PRIMARY KEY (Bill_Number,Menu_Item_Number),
CONSTRAINT FK_BillItem_Bill FOREIGN KEY (Bill_Number) REFERENCES bill (Bill_Number),
CONSTRAINT FK_BillItem_MenuItemNumber FOREIGN KEY (Menu_Item_Number) REFERENCES Menu_Item_Ingredient(Menu_Item_Number),
CONSTRAINT CK_BillItem_Discount CHECK (Discount BETWEEN 0 AND 100)
);
Your problem is with the constraints,
A foreign key constraint will be used to give reference to a column in another table, in your queries you have given constraints like below -
"CONSTRAINT FK_BillItem_Bill Foreign key (Bill_Number) References Primary(Bill_Number), what are you trying to do with this?
The syntax you need to use should be -
CONSTRAINT constraint_name FOREIGN KEY (column_in_current_table) REFERENCES Other_Table_Name(column_name_you_want_to_refer_in_other_table)
As far as I've seen, this will not work, you cannot use DEFAULT in a check constraint.
constraint CK_BillItem_SellingPrice check (Selling_Price >= 0 OR DEFAULT = 0)
If you want to enforce a DEFAULT constraint, you have to use something as below -
CREATE TABLE Persons (
ID int NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
City varchar(255) DEFAULT 'Sandnes'
);
Your final table can be as follows -
CREATE TABLE Bill_Item
(
Bill_Number Number(6,0) constraint NN_BillItem_BillNumber not null,
--CONSTRAINT FK_BillItem_Bill Foreign key (Bill_Number) References Primary(Bill_Number),
Menu_Item_Number Number(5,0) CONSTRAINT NN_BillItem_MenuItemNumber Not null,
--CONSTRAINT FK_BillItem_MenuItemNumber Foreign Key (Menu_Item_Number) References Primary(Menu_Item_Number),
Discount Number(5,2) CONSTRAINT N_BillItem_Discount Null
CONSTRAINT CK_BillItem_Discount Check (Discount BETWEEN 0 and 100),
--colum Discount format '%'00.00,
Quaintity_Sold Number(3,0)CONSTRAINT NN_BillItem_QuaintitySold not null,
Selling_Price Number(6,2) DEFAULT 0.0 CONSTRAINT NN_BillItem_SellingPrice not null, -- You can remove "DEFAULT 0.0" if you do not want to default your Selling_Price to 0.0
constraint CK_BillItem_SellingPrice check (Selling_Price >= 0),
CONSTRAINT PK_Bill_MenuItem Primary key (Bill_Number,Menu_Item_Number)
);
All of your other tables also have the same issue, remove the DEFAULT from check constraint as I did in the above example, and specify "Default" constraint at the column definition itself.
Also, create the table which will be referenced in other tables first, for example, your second table "Bill" has a foreign key constraint which is referencing to "Waiter" table, so you have to create "Waiter" table first.
If you are still having concerns let me know.
CREATE TABLE Booking (

ERROR at line 10:

In Car table C_ID is primary key. I don't understand why it's saying invalid identifier.
CONSTRAINT FK_CarBooking FOREIGN KEY (C_ID)
REFERENCES Car(C_ID)
The first C_ID must exist within the table Booking and the second in the Car table.
In order to solve this problem, add a field named C_ID inside the Booking table.
