I have a database that holds information in many tables. 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

I have an .asp page
that correctly queries a table and returns data if a 'job number' and
week ending date exist and the user can update the information that is
there. What I need to do is, if a record does not exist the page
needs to create one and then refresh/requery so the user can edit the
data. Any suggestions on how to accomplish this?
How can I check if a table exists in an access database using (asp with

We have two tables EmpProfile and holidaysrequest tables.
EmpProfile has fields
EmpNo
Firstname
Lastname etc
HolidayRequests has fields
EmpNo
FromDate
ToDate
holiday requests table stores the dates employees have booked as holidays.
I want to write a query which will be used by ASP page to display everyone
who have not booked 29th - 31st Dec as days off.
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?
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
%>
I populate a recordset and dump it into an array. How can I check if a value exist in the array? I want to check if the c_Member_mgr has a particular value or not?
Dim rs2
set rs2 = Server.CreateObject("ADODB.Recordset")
rs2.open sub_Emp_Source, Conn
Dim aSubordinates
If not rs2.EOF then
aSubordinates = rs2.GetRows()
'Close Recordset to use the new array with the 2 columns data
rs2.Close()
set rs2 = Nothing
'Declare Constants for the above SQL columns for better readability
'Use these Constants instead of referring to the array numeric indexes
Const c_Member_Mgr = 0
Const c_Subordinate = 1
Const c_EmpID = 3
Const c_EmpName = 4
I'm building some dynamic image links based on if the image file exists. How can I check 'if files exists' using asp or javascript? I've messed around some with FileSystemObject but so far no success.

View Replies View Relatedis 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?

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 want to check whether a particular table exists or not in a database as we check whether a particular record exists in the table using Count(*) function.I get the table name from the user and will have to check whether the entry that he has given is a valid one or not. how to do this?

View Replies View RelatedYou'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?

View Replies View RelatedI 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?
