Question

Display a found record on a data access page

Asked by: w100ktn

dim i
dim rs
dim fld
dim FieldCount

FieldCount = MSODSC.DefaultRecordset.Fields.Count
Below is the code I found on MS support page. Users enter a text t search for in txtSearch and the code will search thru all fields in the db to find a matching record. However, in the "for" loop of the code, it appears to me that after the matching record is found, the for loop terminates and the matching record is not shown on the form.

I'm new to MS Script Editor, so don't know the code. I'd like to have the for loop terminate when the 1st matching record is found and this record is displayed on the form. Any help is greatly appreciated.

set rs = MSODSC.DefaultRecordset
for i = 0 to FieldCount -1
      set fld = rs.Fields(i)
      rs.Find fld.name & " = '" & txtSearch.value & "'", 0, 1, 1
             
      if rs.EOF then
            rs.MoveFirst
      else
            'HOW TO SHOW THE FIRST MATCHING RECORD ON THE FORM (I MEAN THE DATA ACCESS PAGE)???
            exit for
      end if
next

set fld = nothing
set rs =  nothing

You'll also want this:

Dim IsFound As Boolean
IsFound = False

In the loop, when you have found a record:

 if rs.EOF then
          rs.MoveFirst
     else
          'HOW TO SHOW THE FIRST MATCHING RECORD ON THE FORM (I MEAN THE DATA ACCESS PAGE)???
          IsFound = True
          exit for
     end if

Just outside the loop (right after 'Next'):

' Current record has your information...use html/asp to put out the values
%>
MyField1 = <%= rs!MyField1 %>
etc...
<%
set fld = Nothing
set rs = Nothing
%>

Understand?

No, I don't. Just looking at the logic, you added a boolean variable, but I don't see this var helping in "bookmarking" the first found record. "exit for"  doesn't depend on the value of IsFound.

I tried your solutions anyhow. However, my ASP/HTML knowledge is extremely limited. So I added a line to display the cust_num of the found record as in the code below bu there is an error that I don't know how to debug.

Any further help is greatly appreciated.

dim i
dim rs
dim fld
dim FieldCount
dim IsFound
IsFound = False

FieldCount = MSODSC.DefaultRecordset.Fields.Count

set rs = MSODSC.DefaultRecordset

for i = 0 to FieldCount - 1
      set fld = rs.Fields(i)
      rs.Find name & " = '" & txtSearch.value & "*'", 0, 1, 1
      if rs.EOF then
            rs.MoveFirst
      else
            IsFound = True
            exit for
      end if
next

txtcust_num.value = rs!cust_num            'THERE IS AN ERROR HERE...NOT COMPILED

set fld = Nothing
set rs  = Nothing

My apologies...I gave you syntax for VBA.  :)

<%
' You are looking for a text value in ANY field in the recordset.
' Start looking at field 0, and continue through all fields.  First
' match stops the search.

for i = 0 to FieldCount - 1

     'Commence a find based on one of the fields
     rs.Find rs.Fields(i).Name & " = '" & txtSearch.value & "*'", 0, 1, 1

     ' if rs.EOF=True, no match was found
     ' reset the recordset position, and go to the next field to search
     if rs.EOF then
          rs.MoveFirst
     else

     ' if rs.EOF=False, a match was found.  
     ' set the boolean flag and exit the loop
          IsFound = True
          exit for
     end if
next

' There may be other code here...the next line skips
' to writing the record out to the page.
' The boolean flag was to indicate if a record was found or not.

if (IsFound) then %>
     txtcust_num.value = <%= rs.Fields("Cust_Num").Value %>
<% end if %>

BTW:

>>> you added a boolean variable, but I don't see this var helping in "bookmarking"

No, it doesn't.  It simply tells the script whether or not a match was found before the For..Next loop exited.  If the boolean if false, no match was found, and there is no record to print out.  The .Find method bookmarks the record as a result of its search...there is no need for a secondary bookmark unless you are acting on a clone.
