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.

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.
Inserting NULL Values
How do I tell my SQL Server database to insert a NULL value for an empty string. Like if I set a value to null in ASP like this: x = null then it inserts as empty in to the database, how do I get it to insert a reall null value?

Null Values From Recordset
I'm reading records from a recordset and placing them in a table. One of these fields is a date value and I format it using the following:

If this field contains no data, how can I display it without getting an error?
Inlcude Null Values In Result Set
I'm working with an Access DB, and two tables. This is going to be ported to MS SQL shortly. The tables are category and merchantcategory, and the link is on category.id and merchantcategory.category_id.
*** Category Table ***
id, category
1, apples
2, oranges
3, lemons
*** Merchantcategory Table ***
id, category_id, merchant_id
1, 1, 1
2, 3, 4
3, 3, 19
What I need to do is something like
SELECT category, count(merchant_id) AS merchants
FROM category, merchantcategory
WHERE category.id = merchantcategory.category_id
GROUP BY category
ORDER BY category
But, I need the merchants column to either return 0 or NULL for those categories that do not have an associated merchant. I would like to see something like:
1, 1
2, 0
3, 2
A. Is this possible?
B. If it is, what do I need to do to get the result? I would prefer not to have a bunch of record sets and loops.
Problem With Len() Function & Null Values
i've come across a real head-hurter. I'm looping through a recordset and
response.writing it's rows out with no problem except 1 field. The field
type is varchar and contains words like meeting, holiday, etc.
Problem is, I'm trying to render a "n/a" when the field is null as in
LISTING 1 below. My code isn't catching the null values. How can I test for
null values? I could swear I've successfully used the Len() test like below
successfully on similiar null varchar fields, but perhaps not.
Any ideas?
LISTING 1:
If Len(objRS(7)) < 1 Then
xTeamName= "n/a" ' this is problem line
Else
xTeamName = objRS(7)
End If
Request.querystring, All Values If Empty?
How do I get all walues if my querystring is empty?
If I have a table with let's say 10 rows/records, (ID 1-10). I then have a
recordset with request.querystring("id") and get the record having the id
thats shown in the address bar ("..com?id=4" would get the record with the
id 4). How do I get all records if the querystring is empty ("..com")

Passing Values To Subroutines - Empty Returns
I'm having a bit of trouble with a subroutine I am calling when it is
invoked for the first time. When the subroutine runs, I expect it to return

Getting The Count From Database Where All Initial Values Are Empty
I have a registration form that I'm making and I need to get the count of available spots for each class session. I can't get the array to return something like "0,0,0,0,0,0". Is there a way to do this? There are 6 total classes and they are named 1, 2, 3, 4, 5, and 6.
When you start out, each count will be 0 (meaning no one signed up yet) which makes the openSpots variable equal to 35 (maximum # allowed). Code:
Why Paramater Values Are NULL When Page Is In EXCEL Format?
I have 3 asp pages. The first page (login.asp) takes the parameter values(userid, groupid, locationid and deptid) based on the login (validate using a table). On submit the page params.asp is executed. Here the user has to select the filtering.
Then the page results.asp is executed. When the result is in excel format only the parameter value p_attdate (p_attdate is the value on page params.asp) contains a value.
The value of p_gid(p_gid is a session variable) remain null. BUT when the output is in html format, the parameter value p_gid return the correct value. I want the output to be in excel format but the sql statement is returning the wrong result. Only p_attdate is returning the correct value. I think because p_attdate is a form variable.
Can anyone tell me why value of p_gid is always null when the output is in excel format???
SQL Server 'text' Data Type Values Always Empty?
I've got a SQL server database, and am using ASP to create a simple recordset.
Everything is fine, except that one column of the database is of 'text' data type. I can't seem to be able to pull anything from this field in my ASP script. All names and variables are correct, and there is data in the text field, it just comes out blank when I pull this field into my recordset.

Is Not Null
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.

Not Null Value
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.

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.
Null
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 Replies View RelatedWhen 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

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?
