Null Insertion
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 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.

My page is acting as if it is working but it is not depositing the values into the db. Should I be using a update query? My response.write statement is perfect as follows:

I have a lil text box that I use to insert into a db. It inserts fine, but anytime i post something like
he said "i don't know" how to do this
the only thing that shows up is everything before the quote.
Am I suppose to be doing a replace for quotes also or does it only apply to apostrophes?

A page I'm working on contains a registration form which is supposed to a) update an Access database using ASP and b) email the contents of the submitted form to the camp administrator.
This is my first experience with ASP, and with any kind of database interfacing language, for that matter. Currently I'm struggling with the record insertion. I'll worry about email afterwards.
I'm using Dreamweaver 8, which is generating all the code for me. I have a testing server set up on my local machine (in my working directory, in fact). I've told DW to connect to the databse (located in %siteroot%/database) through the testing server using a DSN (same DSN as on the web server). Code:

I'm trying to write a page that will accept form POST method variables from another page and save them to an Access database via a DSN connection. I'm using code like this:
<%
SQL = "INSERT INTO myTable (postVar1,postVar2,postVar3)"
SQL = SQL & " VALUES ('" & request.form("postVar1") & "','" & request.form("postVar2") & "','" & request.form("postVar3") & "')"
dsnConn.execute(mySQL)
%>
I'd like to make sure that I clean up the text that the user inputs before trying to send it to the database. Can someone please give me an example of what ASP code I need use to get rid of quotes, slashes, and anything else a user could enter that might mess up the SQL insert?

I have a Dynamic product page that displays the items using "DO UNTIL rs.EOF" and I have assigned form input type to be hidden(for some) for information that I would like to retrieve. On the product page I have a "Add to Cart" button which points to my "addCart.asp".
addCart.asp is where I would insert the items into a Table called "cartItems" in the Database when the user clicks on the "Add to Cart" button.
My "addCart.asp" now generates a "Syntax error in INSERT INTO statement." which I think is caused by my inability to filter for the values from the product page and insert it into the "cartItems" table. Code:

I am using ASP Upload to upload an image to a website. I have other form fields in the form that are used to obtain data and are inserted into an access database. This occurs on the same page as the page that upload the image. Everything works fine except it inserts each record twice into the database. Anyone have an idea what causes this or what I can do to make it only insert once. I am useing the progress bar and don't know if that has anything to do with it. Here is my code.
Set rsPhoto = Server.CreateObject("ADODB.RecordSet")
Set Upload = Server.CreateObject("Persits.Upload.1")
Upload.ProgressID = Request.QueryString("PID")
Upload.SetMaxSize 500000, True
Upload.Save ....

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.

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 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.

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...
