I'm using the following code to, firstly erase any old logins the user has. Then to check whether the page has been idle for longer than 30 minutes or not. If it has been idle for longer than 30 mins then the user will be required to input their password again. However it's not working! Code:
View RepliesI have an interesting situation that needs to be addressed ASAP.
I am running a standard SQL Query in ASP to retrieve some rows/columns from a table that's on a SQL Server 2000 database. I put the results of that query into a RecordSet, and then use the GetRows function to push the results that are in the recordset into an array variable. In the query that I am running, 39 columns and 2 rows are returned.
The GetRows function appears to be working - the array variable is being created with the proper dimensions. However, the values of the different "cells" of the array are not showing up correctly. The first and the last column values for each row are correct, yet everything else in between is blank, empty, NULL, or whatever.
In other words: ArrayVariable(0,0) shows up correctly, ArrayVariable(38,0) shows up correctly, but everything in between is null.
I did a test on the RecordSet and discovered that it was the culprit - it wasn't being filled in properly. This is strange, though, because the select query that I run in the ASP code to create the recordset returns perfect results when I run it on the SQL Server 2K database.
I have created a table. How do I limit the result of that table to only show the entries that have the "address" filled in. In Access here is the sql coding to acheive the results.
SELECT Dropoffs.City, Dropoffs.StateInitials, Dropoffs.AcceptedItems, Dropoffs.MoreInfo, zipcodes.Address
FROM zipcodes, Dropoffs
WHERE (((zipcodes.Address) Is Not Null));
How do I set this up in my VBSCRIPT page?
Here is my working page so that you can see what I am trying to acheive. When the page comes up you can type 45255 for the zipcode.
I try to select the not null value from the database in column comment.
select s.ques_no, s.task_no, s.goal_no, g.comment from step_tab s, gen_tab g where s.id = g.id and g.comment is not null
But it still return all the null value.
Can anyone please tell me why?
Besides that, why i can't increase the number that i selected from the database.
id_no = rs("id_no")
id_no = cint(id_no") + 1
Why the id_no never increase even i had "+1"?
I might be doing this wrong but I am modifying the body tag depending on what a recordset tells me.
It works fine if the value exist, but if it is returned null then I can't get it to work ...
I had set up the following 'trouble-shooting' code to determine how a certain value was being 'evaluated' for lack of a better term. The field "status" in this example has no value in it.
<%
status = RS("status")
If isnull(status) Then
response.write("status is null")
end if
if status = "" Then
response.write("status has no value")
end if
%>
The database field 'status' has no value in it. If I run the above trouble-shooting code, the first statement "status is null" will print out. If I remove the first if statement and use the second if statement 'if status = "" ...', the statement will NOT print indicating that the value <> "".
Questions: What is the difference between something not having a value and NULL?
Most importantly, what is the PROPER way to check for a field not having a value in it? In the past I have always checked for a 'no value' using double quotes.
Microsoft OLE DB Provider for SQL Server (0x80040E2F)
Cannot insert the value NULL into column 'ContactID', table 'ka0506a.ka0506a.contacts'; column does not allow nulls. INSERT fails.
/submitcontact.asp, line 15
What happened is i used to used MS Access and ContactID is an Autonmuber field, and now my connection is set to MS SQL so it's giving me this error, what's causing this error to happen and how can i change it ?

If I write assignee to the page then the value of assignee will write if it has a value and nothing if it is null.
I have a data entry form. If the user submits the form without entering any data, the record should be inserted with null entries for the respective fields.
But when i execute the INSERT SQL query with these null values, it gives me an error.
This is vat I am doing:
<%
.....
address = request.form("address")
if request.form("Age")= "" then
ageValue=""
.....
.....
%>
I use these values in SQL query
This is the SQL statement when the above is executed
" INSERT INTO tblStatistics (Age,address) VALUES (, aaa)"
Because of no value for age, the query is not gettin executed.
I dont want a 0, I want a nul entry (<null>).
Could someone throw some light on how to set the age field to null?

i had select the data from the database. The null value are returned.
How can i convert the null value to integer so that i can add some value for it??
Actually i try to use both of this statement but there's nothing come out...when i try to selecte the data in the database, the null value are returned
if rs("max_id") = "NULL" then
id_no = 1
response.write "id_no = " &id_no& "<br>"

and
if rs("max_id") = "" then
id_no = 1
response.write "id_no = " &id_no& "<br>"

I have 2 questions about SQL server. First, what should i do about allowing NULL values when designing the database? What difference does it make? And if I disallow NULL values, should i enter default values?
Second, when adding new records to database with recordset.addnew, what SELECT statment, cursor, and lock type should i use?
I've always used "SELECT * FROM Table" and adOpenStatic, and adLockOptimistic. This SELECT statement looks very inefficient to me, but I don't know what else to use.
I am updating a table depending on the user input that could be left blank for the numeric as well as the string field. I am getting an error if I do the following:
Dim a = null
sql = "update country set number =" & a
If I do ... sql = "update country set number = null", it works fine.
How can I use the variable to change the value to null.
I have set up a database, myDB, in MS Access. one of my Table, myTable, has columns Col1, Col2, ..., Col10. Depending on some scenarios, I insert some values in some (but not all) of the columns. Now I want to delete those records that their col3 is null or nothing is set.
I used col3= '' and col3=NULL in the below statement
objRS.Open "SELECT * FROM myTable WHERE col3 = '' ", myDB, , , adCmdText
but none of them works.How to delete a record based on Null value filtering?
I am new to using the filter property. When I try publishDate = '' I

Why does this not work? Field is for SURE null in DB if no image uploaded.
Is there an easier way to check if any of the fields returned in a select statement have null values? After running this command:
set rs = conn.execute("select A,B,C,D,E,F,G,H,I,J from SomeTable
where...")
I could check each field this way:
If IsNull(rs("A") Then
Response.Write("The value of A is null")
Else
Response.Write("The value of A is " & rs("A"))
End If
If IsNull(rs("B") Then
Response.Write("The value of B is null")
Else
Response.Write("The value of B is " & rs("B"))
End If
If IsNull(rs("C") Then
Response.Write("The value of C is null")
Else
Response.Write("The value of C is " & rs("C"))
End If
etc.
But is there a simpler way? Also, my "solution" probably wouldn't work if more than one recordset was returned...
I create a web site in a Windows 2003 server/IIS6, and I used asp pages to get ServerVariables. After I set FrontPage Extension 2002, some ServerVariables like LOGON_USER become null. Any body has an idea?

How to do subj ?I tried:
date1=NULL
strSQL = "INSERT t (mydate) VALUES("&date1&")"
i tried with ' ' and without, tried "''", i tried allmost all variations &because i cant put NULL, i have error in my main strSQL.
Is there anything wrong with this query. Sometime it works sometime it doesn't.

is there a better more efficient way of doing this?

I have came across a problem in my Client Update form.
The form gets the users details from the database and
displays them in the relevant fields. I have noticed that
if the contents in the telephone field are removed then
when they upate it doesnt allow the update.
So i assume that there MUST be some sort of numerical number
in the telephone field. Code:
I have a form where the user inserts data. The DB is access and the table is made up of 15 columns.
5 of them are not text. The columns that aren't text if the user leaves them blank it won't insert. 2 are dates, 2 are currency, and 1 is a number. All these columns are defined as NOT required this doesn't make and sense to me. This is part of the code. Code:
<a href="#" onclick="javascript:if (checkFields()) {document.action='newPage.asp?insert=1&action=par';document.finsert.submit();}"><img src="myPic.gif" border="0"></a>
Why Request("insert") is 1, as I expect, but Request("action") is NULL?
What's wrong with it?
