I WAS having problems. Solved it myself. I'll edit to show the working query for those who could use an example...
I'm having a multiple condition problem in my query statement. I know the what the result should be, but I have something wrong...
Here's the query:
set GetNADs = server.CreateObject("ADODB.Recordset")
set GetNADs.ActiveConnection = adoConnection ......
what s the correct syntax of setting a condition with a variable that is retrieved from database like in the example below:
dim x
x = 9
if rsTypes("one") = x then
response.write ("error")
I want to check a another field and if its got info in it i want it to do the then bit, if the field thats checked has no info then its off to else
can some one give me a quick hand on what it should look like?
<%If Your_Condition_Here Then
Response.Write("<form ACTION=""=MM_editAction"" METHOD=""POST'""name=""form1"">")
Response.Write("<input type=""text"" name=""textfield"" value=""(tpwimportrs.Fields.Item(""comments"").Value)"">")
Response.Write("<input type=""hidden"" name=""MM_update"" value=""form1""><input type=""hidden"" name=""MM_recordId"" value=""tpwimportrs.Fields.Item(""ID"").Value "">")
Repsonse.Write("</form>")
Else
' Do Nothing
End If%>

If I want to remove the session object, do each of the following does
the same job? Which one is the best?
1 --> set session("testobj") = null
2 --> set session("testobj") = nothing
3 --> Session.Contents.Remove("testobj")
If I want to check if the session object is not exist, which is the
best option?
1 --> if (session("testobj") = null) then ...
2 --> if (session("testobj") = nothing) then ...
3 --> if (isobject(session("testobj"))) then ...
I have set up a table of Ticket Types. Most of these only have a ticket number but one type also has a reference number.

else response.write rs("priority") %></td>
But where would i put the font tag and the colour, so it coloured the priorities marked as high red?
I am trying to update and append to an existing XML file. However I seem to be stuck. I am using ASP as my scripting language.

When there are no records for the certain row in my table I recieve this error:
ADODB.Field error '80020009'
Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.
/admin/Fixture.asp, line 0
I'm trying to deal with a few records in a db that are missing data in one or more fields, which breaks my page, causing a BOF or EOF error, since the recordset is empty.
I can check for an initial EOF, before any traversing of the records, but don't know how exactly to bypass execution of the record accessing from there.
I am working with an array that I am populating off my database. However, in some instances the array will be empty. Is there any way to determine an empty array besides ubound = 0 (which might mean 1 record in included)?

i want to count all the records in my database where a certain field is empty.
heres my statement:
"SELECT Count(*) As Total FROM table WHERE field1='value' AND field2=' ' "
gives an error.
If it not possible. can the next be done:
1 count all the records.
2 count the records where field2='Yes'
3 subtract the two to get where field 2 is empty?
i know it's just something small, but i can't seem to figure it out. i also tried field2 != 'Yes'
I have a bit of code like this in a do while loop:
Response.Write "<TR><TD>Subject Name</TD>"
Response.Write "<TD>" & objRS("WRsubjectName") & "</TD></TR>"
It works fine, but sometimes the Subject Name field is empty, so instead of a blank space, I'd like to put something like "Empty Recordset" there.
Is there anyway to do this with my current code?
i'm trying to determine if a record is empty and when it's not, it has to show that record

How the heck do you work out what is actually in a db field that appears to be empty? I have fields that appear to be empty but do not seem to evaluate to empty or null, so test using IsEmpty or IsNull are useless, I 'm guessing it contains spaces or non-printing characters of some sort but how do I test for these?

View Replies View RelatedThis one's probably been asked before but I'm tired of trying to find a
solution (if there is one!). I have an asp update page and I'd like to
convert all empty fields to NULL prior to updating the Access db rather than
permitting zero length fields in the db.
Is this possible? Is there any way
to globally declare this for all text fields on the asp page rather than
having to do a whole whack of "if then" formats? Is there something I can
set in the field's properties in Access that will deny zero length yet won't
cause the asp update to choke and return an error?

I have a Recordset that pulls data if 'Promotion' field in data base contains 'promo' and subsequently displays data from a field called 'TourTitle' on my ASP page..

I have a login page where I have three different ways to authenticate a
user.
1. Use integrated authentication and read the server variable AUTH_USER and
then verify if this is a valid user from a database. If OK I write some
session cookies and then re-direct to another page placed in the same folder
(which will read the cookie and verify that it is valid). This works OK.
2. Use anonymous login where the user is typing in a username/password which
is checked against a database and if OK I write session cookies and then
re-direct to other page which reads this cookie. This also work OK.
3. Now we read another server variable that is set by a third party oracle
product (don't know much about this product but when I print the value of
the servervariable it is OK). I write some cookies and then redirect to
another page. When I read the cookie now it is empty. If I read the cookie
just before I do my re-direct it is OK but after the re-direct it is empty.
Do you have any sugestion why the cookie becomes emtpy after the re-direct
in the third case but not in the other two? It is the same code doing the
actual reading/writing of the cookies in all three options above.
I have a table in MS Access that's used for users to post announcements on. There's only one problem- if it's empty (meaning there are no announcements), the page returns an error stating that either BOF or EOF is true. Basically, it doesn't like the null status of the table. Is there a way to state something like 'There is nothing currently here.'? I've been playing with this code but it hasn't worked yet:
If an.EOF=an.BOF Then
Response.Write("There are currently no system announcements.")
Else
do while not an.eof
'This starts a loop that lists them all

I have a form with three fields.The data from each field is sent to seperate tables in the database. If the user only enters info in one field then I only want that data to be sent. Instead empty fields are being sent to the database.I've tried

rs.close
else
rs.update
I always run into issues when a record set is returned empty because the WHERE clause in my SQL weeds everything out. What do you think is the most elegant way to test if there are any records to loop through?
