Hi Experts,
I'm trying to display a time entry from my Teradata database. I format it like this:
<%=FormatDateTime(rs("Arrival_Time"),vbshorttime)%>
The page displays it nicely, but when the time entry in the database is
1/1/0001 00:00:00
I get an error on my ASP page:
error '80020009'

How can this problem be solved?
I appreciate your help.

Trap for a date earlier than some value, then skip displaying that date.

    If rs("Arrival_Time") > "1/1/1970"
           'display time
     Else
          'display some message
     End If

I've tried the following, but unfortunately it displayed the same error:

<td><%If rs("Arrival_Time") > "1/1/1970" Then%><%=FormatDateTime(rs("Arrival_Time"),vbshorttime)%><%else%>-<%end if%></td>

All times are displayed on my ASP page, except for the ones that show as 1/1/0001 00:00:00 in the database.

Hmm.

Maybe try...
   If CDate(rs("Arrival_Time")) > CDate("1/1/1970")
           'display time
     Else
          'display some message
     End If


It's been a while since I've worked in classic ASP!

I've tried it, but received the same error. When I run the query in SQL Assistant everything is returned. When I run the same on my classic ASP page, the 1/1/0001 00:00:00 values display the error.

Why are you using that as a date?  Non dates should be nulls.

You could try
 

if isdate(rs("Arrival_Time")) then
   response.write "The time is FormatDateTime(rs("Arrival_Time"),vbshorttime)
   else
   response.write "I don't know the time"
end if

if instr("0001",cstr(rs("Arrival_Time"))) then
   response.write "I don't know the time"  
   else
   response.write "The time is FormatDateTime(rs("Arrival_Time"),vbshorttime) 
end if

Thank you very much for your attention. It turned out that I didn't have to change anything on my ASP page. I had to change the SQL and cast Arrival_Time as a char(19)  

CAST(CAST(Arrival_Time AS FORMAT 'HH:MI') AS CHAR(19))

For some reason my ASP page didn't like timestamps but it works fine when casting the result as a char.
