In my functions I'm using a double-check all the time to trap if a value has
nothing in it and my question is do I need this double-check.
My check line is:
IF IsNull(xxx) OR LEN(xxx) = 0 THEN
blah blah
ELSE
blah blah
END IF
xxx is usually an array built up of data from an ADO recordset so will
LEN(xxx) = 0 cover my zero values or do I still need the IsNull check as
well?
I need help on an "If (IsNull)" issue. I'm opening a record where "Project" is a certain name. If there are publications associated with the project, I need the title "Publications" to print and then a list of the publications. This works great.
I want nothing to print when there are no publications associated with the project. The code below searches the "Magazine" field. If it's empty, nothing prints. The only way I can get this to work is to associate a empty publication to the project so that the query will return at least one record with an empty "Magazine" field. What I need is if the query returns nothing then print nothing.
CODE: ....
there is no row in the table, totally empty so i try to use IsEmpty and it never return true. and isnull and isempty whats the difference?

I have a database that has "thedate" as a required field. The form that I'm using to insert data allows you to leave the date field blank. If left blank, I want to automatically insert today's date.
If I fill in a date, it works fine & the data is inserted. But if I leave it blank I get an error. This is my code:
I need to know how to do this IsNull update statment in ASP:
"UPDATE tblUsers SET username='" & lcUName & "', hash= IIf(IsNull([lcHash]),"",[lcNewHash]), inactive=" & llAct & ", locked=" & llLock & ", isadmin=" & llAdmin & ", attempts=" & lnAttempt & ", lastlogin=" & ldLastLogin & ", onlyreadaccess=" & llOnlyRead & " WHERE UserID = " & lnSetID
i am testing if my memo field (access DB) has anything in it by doing
if isnull(rs("memofld")) then
do this
end if
The script is not picking up a valid value if it is null or not. I have also tried testing for it equalling "" but no lick either.
Read alot of stuff online with people having the same problem but no luck. I have tried selecting the memo field last in the sql query but this makes no difference.
I used this to sum column with nulls and it worked fine but then when I tried to do the same with the next column over, I get "IsNull function requires 2 arguments error".
In my select statement:
Sum(IsNull([1st Qtr],0)) as Sum1QN
The one above worked fine, so I thought I would just do the same for the next column over like so:
Sum(IsNull([2nd Qtr]),0)) as Sum2QN
What is the difference between not isnull(val) and <> ""
can this statement be reduced from
If NumberDep <> "" or not isnull(NumberDep) then HBinsertSQL = ",
NoOfDependants = " & NumberDep
to
If not isnull(NumberDep) then HBinsertSQL = ", NoOfDependants = " &
NumberDep
I would like to know what the difference is and if possible any links that
have a good description

I am working on a website that requires a login before accessing an appointment book application written in ASP.Basically what I want to do is when the customer first clicks on "appointment_book" link, it takes them to the registration form. After they are registered, It will then redirect them to the actual application.
I also want the same thing to happen when a customer clicks on the login link. I want them to login, then get redirected to the appointment_book.
at the moment the customer click on the registratration link and it shows them the registration form, they are then automatically logged in after registration. However, when I click on the Appointment_book link again, it brings me back to registration form. How can I have the link always point to the appointment book after they are registered or logged in?

I have a signup form.
I would like to be able to check for duplicate entries during the signup.
E.g. Check for duplicate
1. Usernames
2. Phone numbers
How could this be achieved ?
My code basically is two fold.
1. A recordset that checks
if not recordset.bof and not recordset.eof then
'do something. And redirect to say the value exists
end if
2. Run a SP to do an insert and authentication
I've got a page that displays product details. One of the fields in my products table is called Include and is set to Yes/No. I use this to distinguish when I want to add that particular record to a recordset and when I don't. For example, I may have 20 products with the name Ash in them and create a recordset which pulls in all Ash products. However, I only want to pull them in when Include is set to Yes (the others aren't ready yet.)
I'm using Dreamweaver and I've setup my product details page to include that Include field with a checkbox. It checks the box if the Include field is set to True. What I would like to do, though, is be able to then uncheck that box and have it update that field to False, or No. Right now, when I uncheck the box and submit the form I can go back in and it's still showing up in that recordset and the box is still checked when I go to the details page.
i know how to code it in javascript but failed to do it in asp. there are 12 digits of number. exmple like this 871205106599. i want to check every single digit when user clicks Submit button.

View Replies View RelatedI am trying to create a database submition type interface which is dependant on the selection of three check boxes. The form contents will always be the same type of information;;; name address etc. The user must decide which db to write their details to.. So if check box one is selected then it writes to database a. If the other two are individually selected then the script will write the form details to another database b and c. If all three are selected then the script will write to all three databases a b and c .
Is it as simple as creating three connection strings and assigning them to variables
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...
