I am trying to update an integer field in an Access database with a null value (ie, make the field empty). It currently has an integer in it. Here's the code I've tried, which normally works for all other updates:
I have a form with several fields that are updated to a DB as an integer. I am using this code to validate the fields:
iincidentdet = CInt(iincidentdet) If Err.number <> 0 Then strErrorMsg = strErrorMsg & "Your entry for integer_field could " & _ "not be converted to an integer! Remember that integers " & _ "need to be from -32,768 to 32,767.<br />" & vbCrLf Err.Clear End If
when I use my tab to pass by one of the integer fields which should be a 'zero' or null. Is there a way to default the fields to a null value?
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 'brief' field (varchar, 2000 characters) that I sometimes want to leave Null. Getting SQL Server to leave a field Null is no problem, but getting ASP to differentiate a Null field from a populated one is proving a real headache!!
How do you do this? I've tried:
If Len(objRS("f_brief")) = 0 Then... etc.
But it seems that Len(objRS("f_brief")) = 2 with a SQL Server database (though I've no idea why!!) Any ideas as to the best way to detect a genuinely Null (not just empty) field in a SQL Server database with ASP?
What's the best way to handle passing a null value to a number field in my Access database? Right now I am getting an INSERT INTO error when I am doing this. I tried doing the following:
Mon = Replace(Request.form("txtNewMon"),"","0") but it doesn't seem to work. Would you suggest doing an IF satement?
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 am trying to send a 'single' data type to a sql server db cell that is formatted for 'decimal' from asp/ado code and it is converting it to an integer. Should I be using some other data type in sql server?
I am trying to reiterate through a for..next..loop using an integer (i). I would like to know when it is either a odd or an even number, insteading of using the simple version below:
if i = 1 or i=3 or i = 5 then Response.Write "<tr " & strRowOdd & ">" & vbcrlf else Response.Write "<tr>" & vbcrlf end if
I have a set of values like name,age,desg,salary,year etc . currently i am getting the values using max(year) and displaying the values year is integer in my sqlserver db If you go thru my code (see attachment) you would be able to understand.
Now the problem is if a person gets promoted or hike in his salary i have to display two differnt salary on the same year how do i do that. currently i am displaying the values based on the max(year) max(year)-1 etc. i cannot modify the database. i have to do some changes on my coding only. Please view my coding as attachment (3000.txt).
For example Name Age Desig Salary Year abc 35 CEO 39000 2004 abc 35 CFO 38000 2003 abc 35 CTO 37000 2002 abc 35 CTO 35000 2001 abc 35 Direcotr30000 2001

we have a recordset return by a stored procedure from MS SQL. basically this recordset is an integer value, but when we are checking is value something strange happens :
if RS(0) = -1 then ... end
for example RS(0)=46 and anyway our program runs what is inside the if ...end structure..
how can we cast -1 to integer... something like in C++ : (int)(-1).... in order to make sure that -1 in integer.
I put in a request recently for a script which would return 9 random numbers between 1 and 30. I got a reply which gave me this script, which writes them out.
It works great, but in the loop that writes them out, instead I would like to assign each value to a variable, such as img1,img2,img3,img4, etc. in the for loop, is this possible, or should I write out 9 statement lines, each assigning a value to a variable. I intend to plug the values into a java applet which rotates images.
Come to think of it, I could just put each value of the array right into the img tag, no? <img src="images/<%=random_number(1)=>.jpg"> Code:
If Request.Form("resScreen") = "1024x768" Then screenSize = "big" Else screenSize = "small" End If
this works fine, but when this page is reloaded, it doesn't find this Request.Form("resScreen") (this form is also on another page, which explains why) but can I store this variable "big" the first time it loads somehow?
For Each objitem in Request.Form if request.form(objitem).count > 0 then For intLoop = 1 to Request.Form(objitem).count Objitem = request.form(objitem) End if Next
server error in line of "end if"
I want to collect the values from the form and assign a variable to each value field
I am using Visual Studio I have created a website using HTML code and the pages look fine I now need to do the following.
I have a picture where if some one clicks on it it then needs to query an SQL database and return on a different page the results. How do I assign a sql database to my website and how do I connect to it ?
is any way possible to convert a string, which is a string of a number, to an integer (using VBScript). If not, are there any other solutions to have a number that is a string, and add one to increase that number?
I get the EmpID from the form which is a variant. When I do the following, I get an overflow error. Can you suggest of a way I can convert this EmpID to a number?Code:
'Get the EmpID from the form strEmpID = cInt(Request.Form("empid"))
I am calling a javascript function in my asp. I am passing a recordset value, a 7 digit integer, to this javascript function. However, in the function this value is not coming in correctly. say for example i am passing 0360001, in the function when i pass it to another window, its going as 122881.
I am asuming its because of the size of the default integer data type. If you think thats the reason, how can set a long integer data type to this value, if that can be done in asp.
What is the function in ASP to see if an object / string is an integer?
I want to check the contents of a form, and if it's an integer, i.e a number, do something, else if it's a word do something else, and I'm not sure howto?
I have a form, that has a drop down menu with number of options eb. home, work, mobile etc. However when the choice is added to the database table it appears as a number inside the table, even though the field in the table is set to a text value (it is an MS Access DB) Why is this?
I'm retrieving the screen resoltion with javascript code, but i can't assign the correct value to asp. the response.write is displaying zero (0) for screen res., although when i do a document.write in the javascript part, then my screen res. is 1004 ...
