Checking A Table Exists
is it possible to check a table exists before opening the record set? We have a sql query that requests information from a table depending on what information the user enters. So if the user enters information that requests a table that does not exist then I get the following error -:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E37)
[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'y2005m12'
therefore is there a way to check the table exists before running the query or opening the recordset, and therefore redirecting the user to a different pages informing them of the problem?
Check Whether A Table Exists

View Replies View RelatedHow To Tell If A Database Table Exists?
You'd think this would be the most basic sql query in the world but noooooo!
I've tried this:
on error resume next
strsql = "SELECT * FROM " & session("TablePrefix") & CurrentTable
SET rs = conn.execute(strsql)
tableExists = 0
if (Err.number = 0) then
tableExists = 1
end if
But it doesn't return an error if the table doesn't exist. I'm searching on
the internet and hitting these long complicatred solutions involving the
database "shema". Surely there is a simple way of telling with one line of
sql if a table exists or not?

I have created an "Update" and an "Insert" form in dreamweaver MX 2004 which work fine but it allows me to add duplicate names in to the database. Does anyone know of any codeto stop this. If possible i would like it to bring up a pop up saying "Client Name Already Exists" etc

How Do I Check To See If Oracle SID Exists?
I have built a page that lists all our databases, the
users connected to each database, and what application
they are using. Because these databases are moved, or
removed from time to time I need to check if the database
still exists before trying to query it. Otherwise I get
funny SID errors when it tries to process this command:-
Conn4.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=CD;" & _
"User Id=username;" & _
"Password=password"
Can this be done in ASP or should I be querying the error
collection or something?
FileSystemObject To See If An Image Exists.
Just wondering if someone could look at this and see where I may be going wrong. The basic concept is to use FileSystemObject to see if an image exists. If it does, display the image. If not, display image does not exists message.
<%
Set fs=Server.CreateObject("Scripting.FileSystemObject")
strFilename = ="e:path oimageprodPixscienceTN" &
(RecordSet1.Fields.Item("ID").Value) & ".jpg"
If (fs.FileExists(strFilename))=true Then %>
<%=(Recordset1.Fields.Item("ID").Value)%>
<%
Else
Response.Write("No Image Available")
End If
set fs=nothing
%>

'Close Recordset to use the new array with the 2 columns data
rs2.Close()

Redirect If Record Already Exists
I'm wanting to do a simple controlled voting page. I too our webserver off anonymous and everyone who accesses the website is a domain authenticated user. I've already done some control structure pages based on Request.ServerVariables("AUTH_USER"), which works great. That's also how I would do this page, in my basic thinking.
My idea is to have an access database with two tables. One table will have the vote written to it and the other table will have the AUTH_USER written to it when the employee casts their vote.
I'm wondering how I would do a test against that table to see if their name has already been written to the table. So, if an employee votes already, when they go to vote again, their user logon would be tested against all entries in the table and if it exists, the vote would not be written and they would be redirected to another page that politely tells them they've already voted.

I have a left menu that is accessed and displayed via XMLHTTP (it resides on the same server). Some sections of the web site don't have a "menu.asp", so a "Page Not Found" page is returned, which doesn't look great in the menu column.. Is there a way to know if a page exists before using xml.responseText to pull it?

View Replies View RelatedTesting To See If Image Exists Before Displaying It
I dont know if this is the right place to ask this but I have a database which contains shop details, each of which can have several images associated with it. In the database I am just storing the image paths, the actual images are held on a remote server.
I am able to grab the pathnames from the database and then use the following code to loop through the recordset displaying the associated image(s).
While NOT rs.EOF
Response.Write("<img src=""servernameImages" & rs.Fields(0) & """ width=""150"" height=""150"">")

My question is, in the event of one of the images not being found, it just displays a red cross, is there any way of testing to see if the image exists before I try and display it?
