Resolution to the "ORA-01843 Not a valid month" Error

?á

I have seen many developers (specifically those who deal with ORACLE
backends) knocking themselves out (i was one of them) with this strange
error while trying to execute an SQL query with a date field in it.

For some strange reason, Oracle seems to react with your date format
'mm/dd/yyyy' (or 'dd/mm/yyyy')
and raises this error.

The first thing i did, was to check whether the registry value
HKEY_LOCAL_MACHINESoftwareORACLE ls_date_format?á was of the format
"dd/mm/yyyy".

And it was!! After i tried many things, i returned to that key and i
changed the format. Still nothing. This key seems to have no effect to the way
ORACLE databases handle date values.

I went back?áto my source and after the line where my connection?áto the
ORACLE database was initialized, i wrote :

strSQL?á?á= "ALTER SESSION SET NLS_DATE_FORMAT =
'DD/MM/YYYY'"

{The following?áline applies to Oracle Objects for OLE ( aka OO4O). If
you use ADO, RDO, DAO, ODBC API etc etc write it in it's relative format}.

?ámyOraDB.ExecuteSQL (strSQL)

  
  
  Guess what ppl. It worked!

All my Insert/Update/Delete SQL statements that included a date value where
properly inserted into the Oracle database table. No errors so no problems :-)
