Hi All,
I am trying to create a table, sequence, and trigger with the following SQL and am getting the error:

ORA-00922: missing or invalid option


CREATE TABLE "DATA_INVENTORY"
( "ID" INTEGER NOT NULL ENABLE,
"COE_CONTRACT_NUM" VARCHAR2(30),
"PROJ_AREA" VARCHAR2(30),
"STATE" VARCHAR2(30),
"DATA_DATE" VARCHAR2(30) NOT NULL ENABLE,
"NUM_OF_MEDIA" NUMBER,
"DATA_TYPE" VARCHAR2(30)NOT NULL ENABLE,
"MEDIA_TYPE" VARCHAR2(30)NOT NULL ENABLE,
"EXTERNAL_DRIVE_DESCR" VARCHAR2(200),
"ROOM_NUM" VARCHAR2(10)NOT NULL ENABLE,
"DRAWER_NUM" VARCHAR2(30),
"PROJ_CODE" VARCHAR2(30),
"COMPANY" VARCHAR2(30),
"DESCRIPTION" VARCHAR2(200),
"NOTES" VARCHAR2(500),
"INDEX" VARCHAR2(30),
"INDEX_LINK" VARCHAR2(75),
"DATA_LINK" VARCHAR2(75),
"METADATA" VARCHAR2(75),
"METADATA_LINK" VARCHAR2(75),
"DISTRIBUTE" VARCHAR2(30)NOT NULL ENABLE,
"CORPORATE" VARCHAR2(1)NOT NULL ENABLE,

CONSTRAINT "DATA_INVENTORY_PK" PRIMARY KEY ("ID") ENABLE,
CONSTRAINT "DATA_INVENTORY_UK1" UNIQUE ("COE_CONTRACT_NUM", "PROJ_AREA") ENABLE
)
/

CREATE SEQUENCE "DATA_INVENTORY_SEQ" MINVALUE 1 MAXVALUE 999999999999999999999999999 INCREMENT BY 1 START WITH 324 CACHE 20 NOORDER NOCYCLE
/


CREATE OR REPLACE TRIGGER "BI_DATA_INVENTORY"
before insert on "DATA_INVENTORY"
for each row
begin
select "DATA_INVENTORY_SEQ".nextval into :NEW.ID from dual;
end;

/
ALTER TRIGGER "BI_DATA_INVENTORY" ENABLE
/


Does anyone see anything wrong with this?
The create table part is alright but when I add the create sequence etc it causes the error
Thanks,
