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
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.
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 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?
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.
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.
Code: Function FixString(s) If Not IsNull(FixString(s)) then Fixstring = Replace(s, "'", "''") end if End Function error: Microsoft VBScript runtime error '800a001c'
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???
I've looked around the net and searched this message board and haven't been able to find a solution to this problem. An application that I am currently making pushes and pulls data from SQL. One stored procedure is very important and returns many values.
I call this sp many times in my script and wanted to put it in easy to manage function, sub, or whatever works. The problem is that it returns about 10 values that I would need to return from the function back to the standard asp. Code:
I have a list box with five values in it. These are essentially account groups. The user will select one of these values and click on a button. This will update a second list with specific account names depending on what the user selected on the first list.
These account names will be retrieved from an SQL database. Below is the code which sets up the first list and the button. Code:
I am using both VBScript and JavaScript functions in the same ASP file. All I need to do is to retrieve some values which are calculated in the VBScript function, to JavaScript. The call to the VBScript function is made through a JavaScript function. Code:
I want to call a recordset so you can edit the details and then obviously pass the parameters onwards into the db. However, the user guide just says this:
To process other fields in the form, use the Form collection of the upload object the same way you would use the Form collection of the Request object. For example, if your form had a text element named UserName, your processing code would include: Code:
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 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'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:
Microsoft OLE DB Provider for SQL Server (0x80040E2F) Cannot insert the value NULL into column 'ContactID', table 'ka0506a.ka0506a.contacts'; column does not allow nulls. INSERT fails. /submitcontact.asp, line 15
What happened is i used to used MS Access and ContactID is an Autonmuber field, and now my connection is set to MS SQL so it's giving me this error, what's causing this error to happen and how can i change it ?
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 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?
Can someone help with an error? It's a StoreFront store. right after the credit card screen is gives me the error. I get the following:
Microsoft VBScript runtime error '800a005e'

i had select the data from the database. The null value are returned. How can i convert the null value to integer so that i can add some value for it?? Actually i try to use both of this statement but there's nothing come out...when i try to selecte the data in the database, the null value are returned
if rs("max_id") = "NULL" then id_no = 1 response.write "id_no = " &id_no& "<br>" end if
and
if rs("max_id") = "" then id_no = 1 response.write "id_no = " &id_no& "<br>" end if
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.
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?
