Null Value Filtering

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?

RecordSet (and GetRows) Is Retrieving Null Values When They Aren't 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.

Filtering:

I've seen alot of boring forms where a vbscript window will popup if the user submits a bad word in the form. Does anyone know of a tutorial or how to make a bad word filter written in asp that basically goes through an array of bad words and if detected the output would be something like:

<%response.write("Profanity is not allowed.")%>

Asp Form Filtering

I'm looking for an asp page to detect if there are any characters in my
contact form that shouldn't be there. For example, if there is a "<"
character, then this may mean there is html in my contact form, which
is not good. I want to build a string that has all the values of my
textboxes in my contact form. Its not working? Code:

Filtering Results

First, thanks to all who have helped me over the last few weeks !!
I have a form that allows the user to select multiple options.
These are user names:

Fred S
Bob D
Paul G
Dave O

When the form is submitted, I'm getting the details using

user = request.form("user")

this is returning the mutliple options.
What I would like to do is pass all the options to 'user' but at one
point on the results page only show the first user selected, not the
multiple selection

Filtering Records

I need to build an ASP query to search a property size that is between minimum and maximum values (in two text boxes in a form). Here is the SQL statement I use:

mysql="select Center_name, Store_name, Address, Phone, Size, Type, APN
from delamo where size >= '"&min& "'"

But when running the code I got an error message "Data type mismatch in criteria expression."Do I need to dim both min and mas as numbers?

Filtering Data By Date.

I am making a small ASP application that retrieves data from a MS access file and what I'd like the application to do is to retrive only data about items that expire in the current month. I have been trying to figure it out for a while now and have not been able to find the right tools yet.

If I try to explane a little better then the problem is that I need this to work automaticly. I have already made the application retrieve the right data but I have to change the filter conditions every time a new month starts. What I need is to have these changes made automatic.

Filtering Records After Pulling

I have a set of db results that I cannot filter completely in my query and I'm trying to figure out how to eliminate the "duplicate entries" after the fact.

My problem is I'm pulling columns for lot number and transaction time, but some (not all) lot numbers have two transaction times so I can't filter out these double entries with a "DISTINCT" statement in my query since the transaction times are distinct, but I only care about the first one. I'm looping through pulling my results as such: Code:

whose roleID matches a value in an array. There could be any number of

NULL Vs. No Value

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.

When The Field Is Null

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 I write assignee to the page then the value of assignee will write if it has a value and nothing if it is null.

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?

NULL Values In SQL

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.

How can I use the variable to change the value to null.

Check For 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...
