I mean "did any other query which you have exected works fine ?
is just this query is giving some error ?
ora-00904 error says invalid identifier. can you describe your TABLE emp AND see what ALL COLUMNS does it have ?
IN SQL*plus, we USE the below
SQL> DESC EMP -- to see the columns and their data types
also this is direct query without variables, so it should work right.
select userid from emp where userid = '1';
my problem is
i have one table created 2 days ago call emp1 table
emp1 table has only one field call userID
i try to use select on this emp1 table as shown below
select userID from emp1;--> it work
SO i try create a table called emp
emp table has the same field with emp1 which is userID
as shown below
select userID from emp; --> but this new created table shows an error message
state that userID is an invalid identifier. why?

PASSWORD is an oracle keyword which is reserved by oracle for its use though it allows us to use that.
I suggest/advice you to rename the column in emp table to some other name and they query as shown below :
a) alter table emp rename column password to pass_word_1;
b) select userid from emp where password = '22';
Thanks
