Question
ORA-00904:: invalid identifier
I use Oracle 10g express. As I try to create a table with following script, I got error.
Script:
create table USERS (
ID NUMBER(19) not null,
CREATION_DATE TIMESTAMP(3) not null,
COMMENT VARCHAR2(255),
primary key (ID)
)
Error:
ORA-00904:: invalid identifier
SQL State: 42000
Error Code: 904
But when I take out the " COMMENT VARCHAR2(255),", it will be OK. Why? Maybe the keyword COMMENT?
