Java.sql.SQLSyntaxErrorException: ORA-00904: "GROUPID": invalid identifier

Question

I have this Oracle table:
CREATE TABLE USERGROUPS(
  GROUPID INTEGER NOT NULL,
  GROUPNAME VARCHAR2(40 ),
  GROUPSTATUS VARCHAR2(30 ),
  DATEGROUPADDED DATE,
  DATEGROUPLOCKED DATE,
  GROUPEXPIREDATE DATE,
  DESCRIPTION CLOB
/I tried to run this SQL query:
SELECT c.*
FROM
  (SELECT b.*,
    rownum rn
  FROM
    (SELECT a.* FROM USERGROUPS a ORDER BY GROUPID ASC
    ) b
  WHERE rownum <= 5
  ) c
WHERE rn > 10I get this error message in SQL developer when I run it:
ORA-00904: "GROUPID": invalid identifier
00904. 00000 - "%s: invalid identifier"
*Cause:   
*Action:
Error at Line: 5 Column: 25
I also tested this SQL query:
SELECT GROUPID FROM USERGROUPS I get this error:
ORA-00904: "GROUPID": invalid identifier
00904. 00000 - "%s: invalid identifier"
*Cause:   
*Action:
Error at Line: 1 Column: 7
Can you help me to fix the problem?

Answer 1

Are you sure the create table statement executed successfully (with no error)?
Perhaps you use an older version of the table where the column groupid did not exists.
You can check the columns of your table with:
select * from all_tab_columns
where table_name='USERGROUPS'
  and owner='<schema-name>'
order by column_id;Another reason could be, that exist two tables with the same name.
You could check that with
select *
from all_tables
where table_name ='USERGROUPS';hm
