I have a webpage which shows some results upon executing some SQL statements. However, i will met with some problems when the SQL statements return a NULL value therefore i would like to do some error checking such that when the SQL statement returns NULL, i will direct the user to another page.
Is it possible for me to try sth such as:
if strSQL = SELECT .. FROM .. WHERE .. = NULL then
response redirect ...
I'm reading from an Excel spreadsheet to insert the data into a database.
The problem is with a column that contains both numerical and text values. I'm inserting this column into a text field in the database, but for some reason any value that contains a text character, EG K121212, is returning NULL when it's read.
I'm debugging at the moment by writing the values out to the screen using:-
if not isnull(excelrs.fields.item(2).value) then response.write("<td>"&excelrs.fields.item(2).value&"</td>") else response.write("<td>NULL VALUE</td>")
If the column contains 121212 then it writes to the screen. If it contains K121212, it writes NULL VALUE.
I've tried converting the whole column to text; same result. I've tried putting a ' infront of the text values; same result. I'm sure I had this problem before and fixed it, but it's happening again and nothing I try is sorting it.
I have a ASP page that returns and manipulates information from an access table. The information it returns is the figures for each month for certain products.
Basically the page adds up the results returned from each month and then gives a total for the year so far for each product. So we can view the figues for every year back to 2000 to see how the product did. The problem is that when we choose 2006 it returns no values, and I can't see why. The only difference is that for the months that havnt been completed yet - May onwards, there are no entries, not even a '0'. Would this be a problem when adding using the asp page, adding a number to a returned object that contains nothing?
Code:
<img src="/images/thumbs/<% IF rsListProduct("AHFC_Product_ThumbURL") = null THEN %> no_image.gif <%ELSE%><%=rsListProduct("AHFC_Product_ThumbURL")%><%END IF%>" width=50 border=0>
Why does this not work? Field is for SURE null in DB if no image uploaded.
What is a faster/better coding practice?
Method 1:
Code:
Sub myFunction(byRef x)
x = x + 1 ' do something with x
End Sub
x = 7
myFunction(x)
response.write x ' shows 8
Method 2:
Code:
Function myFunction(x)
myFunction = x + 1 ' do something with x
End Function
x = 7
response.write myFunction(x) ' shows 8
Also discuss considerations when there are more than one variables that need to be changed.
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.
Can someone give me an example of how to use a
stored procedure that returns XML data?
I want to call the SP from a VBScript program,

I've created a DLL file that enables you to validate accounts and send emails through the MS Exchange server within the Intranet. This dll can be used from within VB, VBA, VBScript and also ASP VBScript. I'm using it in an ASP page that I've created. The DLL has a "SEND" function that will return a string value containing all the invalid accounts seperated by a semi-colon. A sample of the returning string value would look like, "InvalidAcct1;InvalidAcct2;InvalidAcct3". The DLL works like it is suppose to when used in an ASP, but it will not return the string value. I know the DLL works fine because it returns it when used in a regular VBScript or VB program.Is IIS preventing the string from being returned?
View Replies View RelatedI am using a windows 2000 server with IISLockdown and ISAPI_Rewrite installed on it. I have 2 websites A & B. ASP pages on A are working properly, but when placed one B they return 404 error. All other pages such as txt, html, asp.net work fine on B. Both websites have the same configuration, and use the same ISAPI filters.
A sample cade the is not working is, file name test.asp:

Do you know what needs to be done to fix that?
There are two pages main.asp and phonebook.asp.In the main.asp, there is a textfield, where the phone number will be inserted into it. Next to the textfield, there is an icon that when clicked takes you to the phonebook.asp page.
In the phonebook.asp page, there is a list of the telephone numbers and next to them there is a radiobutton. When one of the radiobuttons is chosen (the telephone number is chosen), the number (value) needs to be inserted in the textfield (main.asp page).How may i do this processing? Preferably i need to use asp together with vbscript or even javascipt.

I have a MS SQL 7.0 table with a large field (> 500 characters). My select statement embedded in my ASP file in an intranet web interface only returns 255 characters. If I run the select statement in Query Analyzer, I can easily change the "Maximum Characters per Column" setting to return the entire field, but that doesn't help me in my ASP web interface. How do I return the entire field through ASP?

I've got a site with PayPal and Google Checkout payment options. The checkout page formats two HTML forms, containing bespoke cart code - one posts to PayPal, the other to Google Checkout.When an order is placed, it needs to be updated back on my site, so that the order is marked as 'paid' in the database. When this is done with PayPal, I just provide a hidden field in the form called 'invoice' containing my id number for that transaction. This is returned in my IPN, and I update the database accordingly. However, I can't find a similar field in Google. Their example code all seems to be in XML and is WAAAAAAAAY more complicated than I need it to be. I just need to send a value with my cart code to Google Checkout, and have that value returned after the transaction has completed.
I've set up Google Callback, and the page is being called and the order is being written to my google log txt file, I just need this to contain my order id number for the transaction so I can just add the logic to update the database based on this id number.
I have a field that is stored in SQL Server in date/time format. On one
page, I only need the date to display. I am able to do this by saying:
DateValue(strLastModified)
However, this returns to me the date in this format:

Instead, I would like to see:
05/10/04, but I am not sure how to do this.

View Replies View RelatedI have written some ASP code that selects some records from a SQL database according to a criteria, if no information is found in the database then it sees there is an End Of File in the object record set and prints the line below:
<%if objRecordset.EOF then Response.Write("No information was found for the record you have entered") %>
My problem is that if no records are found it still tries to print the information that it is looking for and cannot find and thus throws an exception. The code for that is below:
<Table Border="1" BGCOLOR="white">
<% Response.Write "<TR><TD>The date for that record is " & objRecordset("DateTime") & "<br></TD></TR>" %>
I was wondering if anybody could advise me how to return just 100 rows from a database query. In Cold Fusion I'd use the maxrows function, but not sure how to do in ASP (or can I do it in just SQL?). My code is thus :
' Retrieve last 100 records. Query then run through the query building a string
Set objRetrieve = objConn.Execute("SELECT Players_ID, Players_Name, Players_Score FROM Players ORDER BY Players_Score DESC")
I'm back with the same code, which works fine, except for when i ad the block of code that i noted...i get the error message:
ADODB.Field error '800a0bcd'
Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.
/test/testbasket.asp, line 72
which is referring to the strSurvID=adoRSWEBtest4(0)
i know that the query above that is supplying webtest4 with its where check is returning a value. when i take out the noted block of code, the page works fine, and emails all information, including the value that is being checked for in webtest4. Code:
I was under the impression (according to all the tutorials) that a Sub differs from a Function in that it doesn't return a value. Therefore I interpret this as meaning if a function is initialised at the top of a page and called at the bottom the result won't be returned to the place it was called i.e. the bottom of the page.
This clearly isn't right though as both Functions and Subs return a value to where they are call from.I want to display the results of a task in a position on the page that is before the task has been carried out.
Therefore if I create a Sub where I want the result to be displayed I assumed that when I call the Sub it would display the results where I wanted i.e. above the task. This isn't happening?
i have a string that will change and i just want to return the first charecter, how do i do this?

i have a text field that has not been submitted to database by submit button. i want to get the value from it the moment user leaves that text field and pass it another function in ASP that is using vbscript.
the only way i can get it is by ONBLUR event of the text field to get the value in javascript but i am not able to move that value to ASP code.
I have that text value in a variable in javascript but the variable that javascript uses is its local variable. If i put ASP variable in javascript it says it is not defined and gives error. Code:
