ORA-00904: invalid column name

I renamed field in table. When I do desc on this table it shows new name, However when I do SELECT newfieldname from mytable I get following error: ORA-00904.

Why!

Does this query show your column name?
Do you have any miscellaneous characters around the new column name?
Post the results of this query.

Code:

---

SELECT table_name, '|' || column_name || '|', data_type
  FROM all_tab_columns
 WHERE owner      = 'SCHEMAOWNER'    AND
      table_name = 'YOURTABLE_NAME'
 ORDER BY column_id;

---

When you renamed, did you put the new name in double quotes?

I run query below and could see my new column

code:--------------------------------------------------------------------------------
SELECT table_name, '|' || column_name || '|', data_type
FROM all_tab_columns
WHERE owner = 'SCHEMAOWNER' AND
table_name = 'YOURTABLE_NAME'
ORDER BY column_id;

Here is record with new column name

CUSTOMER_SITES |SITE_PRIM_DATA_SOURCE| CHAR

So what happens when you do this?

Code:

---

SELECT SITE_PRIM_DATA_SOURCE
  FROM CUSTOMER_SITES;

ORA-00904: invalid column name

Try posting the sql that you put in as well as all of the output.
There is probably something else that Oracle is telling you.

FYI

tahiti.oracle.com
ORA-00904 string: invalid identifier

Cause: The column name entered is either missing or invalid.

Action: Enter a valid column name. A valid column name must begin with a letter, be less than or equal to 30 characters, and consist of only alphanumeric characters and the special characters $, _, and #. If it contains other characters, then it must be enclosed in double quotation marks. It may not be a reserved word.

I am using very simple test SQL
SELECT SITE_PRIM_DATA_SOURCE
FROM CUSTOMER_SITES

and error output ORA-00904: invalid column name

Howerver if I use old field name in my SQL it works and get result back. Does not make sence to me.

Thanks for looking at this for me!
