hi all,
i am trying to build a crystal reports report and i get this error:
Failed to retrieve data from the database. Details:blah, blah something about the ODBC... [Vendor Code 904]ORA-00904 invalid column name.
So, where exactly should I look into since the ultimate reason for the report to fail seems to be some incompatibility between Oracle 8i and the client application. It is probably more of a CR problem since all queries in SQLPlus on the same table are ok.
If someone has encountered this before, please let me know,
thanks,
kowalsky

"Invalid column name" error is quite obvious. However, here's what Oracle says about it:| Oracle | ORA-00904 invalid column name
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, it must be enclosed in double quotation marks. It may not be a reserved word.

As you've said that all queries work correctly when run in SQL*Plus, hm, that's funny. I don't know Crystal Reports, but - I guess they allow "user-defined columns" as well. These might be "formula columns", "summary columns" and similar.
Could you check whether there are such columns in your report. If it is a formula column, there might be SELECT statement in there which *might* use invalid column name.
