How the heck do you work out what is actually in a db field that appears to be empty? I have fields that appear to be empty but do not seem to evaluate to empty or null, so test using IsEmpty or IsNull are useless, I 'm guessing it contains spaces or non-printing characters of some sort but how do I test for these?
I'm trying to set up a quick if/then/else statement for when the database field returns no results. I'm not getting an error but when the field is EMPTY it still executes the ELSE statement.
<% If rsOffice("FloorPlan") = Empty Then Response.Write ("Not Available") Else Response.Write ("<a href=" _ & rsOffice("FloorPlan") _ & ">View</a>") End If %>
I'm trying to deal with a few records in a db that are missing data in one or more fields, which breaks my page, causing a BOF or EOF error, since the recordset is empty. I can check for an initial EOF, before any traversing of the records, but don't know how exactly to bypass execution of the record accessing from there.
I am working with an array that I am populating off my database. However, in some instances the array will be empty. Is there any way to determine an empty array besides ubound = 0 (which might mean 1 record in included)?
users are entering data, but when they submit the form, once in a while request.forms returns an empty string instead of the string its supposed to get. Anyone seen this behavior before? Is there a solution
i want to count all the records in my database where a certain field is empty.
heres my statement: "SELECT Count(*) As Total FROM table WHERE field1='value' AND field2=' ' "
gives an error. If it not possible. can the next be done: 1 count all the records. 2 count the records where field2='Yes' 3 subtract the two to get where field 2 is empty?
i know it's just something small, but i can't seem to figure it out. i also tried field2 != 'Yes'
It works fine, but sometimes the Subject Name field is empty, so instead of a blank space, I'd like to put something like "Empty Recordset" there. Is there anyway to do this with my current code?
This one's probably been asked before but I'm tired of trying to find a solution (if there is one!). I have an asp update page and I'd like to convert all empty fields to NULL prior to updating the Access db rather than permitting zero length fields in the db.
Is this possible? Is there any way to globally declare this for all text fields on the asp page rather than having to do a whole whack of "if then" formats? Is there something I can set in the field's properties in Access that will deny zero length yet won't cause the asp update to choke and return an error?
I have a Recordset that pulls data if 'Promotion' field in data base contains 'promo' and subsequently displays data from a field called 'TourTitle' on my ASP page..
However if the 'Promotion' field is empty in the database, I get an error on my page.. I have tried to use the following, but it is not working..
I have a login page where I have three different ways to authenticate a user.
1. Use integrated authentication and read the server variable AUTH_USER and then verify if this is a valid user from a database. If OK I write some session cookies and then re-direct to another page placed in the same folder (which will read the cookie and verify that it is valid). This works OK.
2. Use anonymous login where the user is typing in a username/password which is checked against a database and if OK I write session cookies and then re-direct to other page which reads this cookie. This also work OK.
3. Now we read another server variable that is set by a third party oracle product (don't know much about this product but when I print the value of the servervariable it is OK). I write some cookies and then redirect to another page. When I read the cookie now it is empty. If I read the cookie just before I do my re-direct it is OK but after the re-direct it is empty.
Do you have any sugestion why the cookie becomes emtpy after the re-direct in the third case but not in the other two? It is the same code doing the actual reading/writing of the cookies in all three options above.
I have a table in MS Access that's used for users to post announcements on. There's only one problem- if it's empty (meaning there are no announcements), the page returns an error stating that either BOF or EOF is true. Basically, it doesn't like the null status of the table. Is there a way to state something like 'There is nothing currently here.'? I've been playing with this code but it hasn't worked yet:
If an.EOF=an.BOF Then Response.Write("There are currently no system announcements.") Else do while not an.eof 'This starts a loop that lists them all End If
I have a form with three fields.The data from each field is sent to seperate tables in the database. If the user only enters info in one field then I only want that data to be sent. Instead empty fields are being sent to the database.I've tried
I always run into issues when a record set is returned empty because the WHERE clause in my SQL weeds everything out. What do you think is the most elegant way to test if there are any records to loop through?
I am working on a system where a program will send a user to a page e.g. www.mysite.com/customer.asp?id=xxxx (where xxx is the userid). If id=xxxx doesn't exist I want the system to redirect the user to a registration page where he or she can add their info, including the id=xxxx to a an access db. The next time the user uses this software, it will send them to the same (now existing) page. is this possible?
how do you check if a recordset is empty? i am trying to write a code that checks in the database if a field is empty and if it is, it should equal to "No." . here's what i have so far:
If rs("contact")="" then rs("contact")="No" Else rs("contact")=rs("contact") End If
I am getting this error:
ADODB.Recordset (0x800A0CB3) Current Recordset does not support updating. This may be a limitation of the provider, or of the selected locktype.
i have a form with 2 textbox and 2 buttons if i push the 2nd button it summits the form to a process page and add both textbox info into a database( with the check if they are empty), this because the form action is set to go to that page.
but i want the 1st button to do a test if the 1st textfield is empty and if is not i want it to post just the value of the first textbox to another page(process2). i've got the 2nd button working allright but i dont know how to so set up the code to the first button.
i want to test if a recordset is empty then print a sentence Else display the records. i tried if recordset.recordcount = 0 then ..... else and it aint working. i want to use it for a delete.asp page cuz when the table is empty it throws an error.
I'm calling a SQL stored procedure with the folowing code. It seems to work fine but I want to know if it doesn't return any rows and the oRsCatList. eof is not working.
lcDisplayCatList = "Y" Set oConn = Server.CreateObject("ADODB.Connection") oConn.Open Session("strConn") Set oCmd = Server.CreateObject("ADODB.Command") set oCmd.ActiveConnection = oConn oCmd.CommandText = "spCategoryList" oCmd.commandtype = AdCmdStoredProc oCmd.Parameters.Append oCmd.CreateParameter("@CatID", adInteger, adParamInput) oCmd.Parameters("@CatID") = lnCatID set oRsCatList = oCmd.Execute if oRsCatList.EOF then lcDisplayCatList = "N" end if
I need to check each item in an array to see if it is empty or not. The array is created by a bunch of Request.Form's. I think I almost have it but I can't seem to get it right.
I need to check it, and if empty (null) I need to insert something. It can't be empty because it is used on an INSERT SQL thing. I would like it to be something like this:
A for loop running through each of the items in the array An if statement in the loop to check if it is empty or not. I haven't quite got down the If conditions in ASP.
Can one reliably use http_referer to track a user page selections as I appear to be getting BLANK values? I have read that company firewalls etc block this method....
I have a results page with two result boxes and am trying to add 'Show if recordset is empty' for obvious reasons (in Dreamweaver Mx). BUT i've highlighted text (eg, criteria error) for one and used the show if....
which works fine but when i try to add it to the second box (different recordset) it doesn't work, WHY?? Just trying to show a message in case no box is filled or no data retieved on the query of the record set.
I'm listing records from my db and each company has 3 address lines ie address, address2, address3. In most cases 3 and sometimes 2 are empty. As my ASP looks like this
then I end up with the first line of the address and two blank lines. How could I avoid that by checking if the fields have content, only then display them?
I have setup a database for user to upload product image and it name and desciption. Since there is no product upload by user, it will display this error:
ADODB.Field error '800a0bcd'
Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.
/i-Metz/iMetzAdminADs.asp, line 295
Therefore i wrote this script to counter the error:
I have this form that collects text values and I use VBCrLf as delimiters to tell one element from another. Sometimes, I get several empty elements. Is there a way to remove those elements?
I have the following problem, I need to track visitors to my site, to do so I use a session variable called 'session("userid")'. Populated by the code below:
This should give me an almost unique id that looks like yyyymmdd-sessionid (20050305-123456789) etc
The problem I have it that for 99% of people this works just fine, but then there's that 1% that for some reason the Session("userid") just manages to remain blank.
Are the any known issues with firewall's, browsers, personal information protectors etc that block the use of session variables?
Trying to return a Recordset to an ASP and the Recordset is empty. The StorredProc works in the query analyzer and it even works from a quick VB app that I wrote to test it.
The storedproc that I am using is fairly complex (creates some temporary tables and populates them with 'Insert Into Select ...', but the during testing the only Select statements that return visible rows is the final one that returns the finished table with an 'Order By ....'.
I am trying to figure out if I am receiving multiple recordsets or if I am out of environment space. Do the 'Insert Into Select ..' statements return empty or null recordsets ?
