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?
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
there is any way i can check if the database Exists. I mean from the code side. I dont want it to throw me any error thats the reason.

How can i check if a vlaue exists ? Sample to get the idea: Code:

View Replies View RelatedHow can I check if a table exists in an access database using (asp with
javascript)
I have a web page that creates dynamical forms, depending of what kind of product it regards. When the user has chosen a product, data is collected from SQL Server and a form is created.
Some forms contains check boxes and some not. My questions is: How can I check if someone has UNCHECKED a check box? Because if that happens, I want to delete that entry from the database.
Since a form just posts the value of a check box if it is checked, this causes a dilemma.
Any ideas, I can't be the first one having this problem?
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?
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?

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.

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
%>
