Assign A Null Value To Integer Field
I am trying to update an integer field in an Access database with a null value (ie, make the field empty). It currently has an integer in it. Here's the code I've tried, which normally works for all other updates:
set rs = Server.CreateObject("ADODB.Recordset")
rs.ActiveConnection = sConnString
rs.Source = "SELECT * FROM tblFixtures WHERE FixtureID = " & strFixtureIDcurrent
rs.CursorType = 0
rs.CursorLocation = 2
rs.LockType = 3
rs.Open()
rs_numRows = 0
rs("ArticleID") = ""
rs("Result") = ""
rs.update
rs.close
set rs = nothing
However I am getting a Type Mismatch error on the rs("ArticleID") = "" line. Where have I gone wrong?

I have a form with several fields that are updated to a DB as an integer. I am using this code to validate the fields:
iincidentdet = CInt(iincidentdet)
If Err.number <> 0 Then
strErrorMsg = strErrorMsg & "Your entry for integer_field could " & _
"not be converted to an integer! Remember that integers " & _
"need to be from -32,768 to 32,767.<br />" & vbCrLf
Err.Clear
End If
when I use my tab to pass by one of the integer fields which should be a 'zero' or null. Is there a way to default the fields to a null value?

I have a condition that will run depending if a field in the database is NULL. It will not run at all, and I tried various way to write it but none works so far
'not working
If assignee = DBNull Then
'not working
If assignee = null Then
'not working
If assignee = "" Then
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 'brief' field (varchar, 2000 characters) that I sometimes want to leave Null. Getting SQL Server to leave a field Null is no problem, but getting ASP to differentiate a Null field from a populated one is proving a real headache!!
How do you do this? I've tried:
If Len(objRS("f_brief")) = 0 Then... etc.
But it seems that Len(objRS("f_brief")) = 2 with a SQL Server database (though I've no idea why!!) Any ideas as to the best way to detect a genuinely Null (not just empty) field in a SQL Server database with ASP?

What's the best way to handle passing a null value to a number field in my Access database? Right now I am getting an INSERT INTO error when I am doing this. I tried doing the following:
Mon = Replace(Request.form("txtNewMon"),"","0") but it doesn't seem to work. Would you suggest doing an IF satement?

I 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'm adding fields to a table with this code:
sql = "ALTER TABLE companies ADD COLUMN fieldname int"
now "int" gives the number as a whole number but what is the syntax for this value to be allowed to involve decimals?

If i need to search the ticketnumber by using long integer, do i need to include the single quote like the example below.
strsql="Update offsitetape set status='Open' where ticketnumber =' "&problemopen&"' "
When I get the value from the textfield, do I need to convert it to integer or just leave it like that:
problemopen=request.form("tapestextfield")

I am trying to reiterate through a for..next..loop using an integer (i). I would like to know when it is either a odd or an even number, insteading of using the simple version below:
if i = 1 or i=3 or i = 5 then
Response.Write "<tr " & strRowOdd & ">" & vbcrlf
else
Response.Write "<tr>" & vbcrlf
end if
Want to format table rows in a different style.
Any ideas?

we have a recordset return by a stored procedure from MS SQL. basically this recordset is an integer value, but when we are checking is value something strange happens :
if RS(0) = -1 then
...
end
for example RS(0)=46 and anyway our program runs what is inside the if ...end structure..
how can we cast -1 to integer... something like in C++ : (int)(-1).... in order to make sure that -1 in integer.

I put in a request recently for a script which would return 9 random numbers between 1 and 30. I got a reply which gave me this script, which writes them out.
It works great, but in the loop that writes them out, instead I would like to assign each value to a variable, such as img1,img2,img3,img4, etc. in the for loop, is this possible, or should I write out 9 statement lines, each assigning a value to a variable. I intend to plug the values into a java applet which rotates images.
Come to think of it, I could just put each value of the array right into the img tag, no? <img src="images/<%=random_number(1)=>.jpg"> Code:

I have a code somewhat like this:
Dim screenSize
If Request.Form("resScreen") = "1024x768" Then
screenSize = "big"
Else
screenSize = "small"
End If
this works fine, but when this page is reloaded, it doesn't
find this Request.Form("resScreen")
(this form is also on another page, which explains why) but can I store this variable "big" the first time it loads somehow?

I am calling a javascript function in my asp. I am passing a recordset value, a 7 digit integer, to this javascript function. However, in the function this value is not coming in correctly. say for example i am passing 0360001, in the function when i pass it to another window, its going as 122881.
I am asuming its because of the size of the default integer data type. If you think thats the reason, how can set a long integer data type to this value, if that can be done in asp.
