Error messages when sending date-time stamp to Oracle Database

Question

  I have a complex application that communicates with an Oracle database.  One of the table values that gets written to the table is a date-time stamp.  Until recently, the user only required a date, and this was never an error. (The format String used was %d-%b-%Y)  Now they need a time-stamp as well, so I attempted to edit the format string input of the format date/time string function to include the time. I have tried numerous format strings, each of which returns an error on execution.  Depending on which format I use, I get one of 3 different error messages.  The really odd thing is that both the date and time always get stored in Oracle without any problem (regardless of what date-time I use, as long as I include the date and any part of a time stamp - I get the entire timestamp even if I only include %I for the hour).  The only issue is that LabVIEW generates an ODBC error if I try to include the time to the date-time stamp.  In other words, teh date/time stamp writes to the Oracle database, but an ODBC error occurs every time.  I've included a word doc with screen captures of the format strings used, the resultant date/time stamps written to Oracle and the error messages generated within LabVIEW. Any advice would be most appreciated.

Oracle has a standard date format: 12-Mar-2009 that it accepts as a string, but if you want more than that, you need to use the todate() function. I used this string going into the standard LabVIEW ''Format date/time sting vi' 
to_date('%d-%b-%Y %H:%M:%S', 'DD-MON-YYYY HH24:MIS') to create the value needed for Oracle.
Then I use standard format string to create SQL: insert into mytable (mydate) values(%s) and select * from my table where mydate = %s using the string above for %s.
I think you can also define a global format for all time strings but I haven't bothered figuring that out.
