Oracle SQL - "missing keyword" - sql

Question

I am trying to create a simple table in Oracle SQL. The counterpart code works fine in SQL management studio, but not in Oracle APEX.
The following query:
CREATE TABLE Conference(
ConferenceID NUMBER GENERATED ALWAYS AS IDENTITY
(START WITH 100
INCREMENT BY 10
MINVALUE 100
MAXVALUE 100000
NO CYCLE),
Director VARCHAR(25) NOT NULL,
School Size NUMBER NOT NULL,
Location VARCHAR(50) NOT NULL,
CONSTRAINT pk_Conference PRIMARY KEY (ConferenceID)
);
is repeatedly met with the following error:
ORA-02000: missing ( keyword
I have done my due diligence searching for a solution to this problem here, here, and here.
I checked over the identity column section, as well as the Primary Key syntax here, and everything appears to look right. Despite this, I cannot find a solution.

Answer 1

Okay, in the docs, take a look at the identity options for a column definition. It's a small typo in this case - the NOCYCLE option is one word; there's no space.
You have one other problem, which is that School Size is not a valid column name. There's a space in it, and it's not quoted. You could do either School_Size or "School Size". I'd recommend the first one, since double-quoted column names are case-sensitive and really annoying to use.
Edit: Also, they're technically synonyms, but Oracle recommends using VARCHAR2 instead of VARCHAR.
CREATE TABLE Conference(
ConferenceID NUMBER GENERATED ALWAYS AS IDENTITY
(START WITH 100
INCREMENT BY 10
MINVALUE 100
MAXVALUE 100000
NOCYCLE),
Director VARCHAR2(25) NOT NULL,
School_Size NUMBER NOT NULL,
Location VARCHAR2(50) NOT NULL,
CONSTRAINT pk_Conference PRIMARY KEY (ConferenceID)
);
