Hi,
The application has a link with an Oracle database. In the SQL table the field is defined like this : DATE_NAI_IND DATE with NULL
When I try to use this field in a SQL request, for example : select DATE_NAI_IND, COD_ETU from VUE_TRAV_EXT_RVM_RES where TO_CHAR(DATE_NAI_IND,'dd/mm/yy')= "08/08/1997" or DATE_NAI_IND = "08/08/1997"
I always receive the same error : Error, dco2.DatabaseError: (904, 'ORA-00904: Nom de colonne non valide')
Thanks for your help
Here's the action from the Oracle error message guide:
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.
I read that as being that you can't use TO_CHAR() as a column name in your where clause; the TO_CHAR must be on the right-hand-side of the expression e.g. where DATE_NAI_IND = TO_DATE('08/08/1997', 'dd/mm/yyyy') although normally Oracle will do string to date conversion for you automatically. -- Matt Kromer Zope Corporation http://www.zope.com/
