Enumerating Search Results
Topic Last Modified: 2006-06-11
This example shows how to process a returned recordset, accommodating for multivalued and null properties, and how to render the results.
Example
VBScript
Example
'writes property values from a recordset (Rs)
'returned from a SQL query
'The DoResults function writes an HTML table
'for each record (item) in the recordset. In that table
'each property and value are written to a table cell,
'accommodating for null and multivalued properties.
On Error GoTo
Function DoResults(Rs)
'If empty recordset, return error
If Rs.EOF = True Then
On Error Resume Next
Err.Raise adErrNoCurrentRecord
Response.Write "<br><FONT FACE=Arial SIZE=2>No items found, run another query.<p>"
Else
Rs.MoveFirst
Do Until Rs.EOF
'Create a HTML table for each record, make table headings stand out
Response.Write "<FONT FACE=Arial SIZE=2><TABLE BORDER=1 cellpadding=5 cellspacing=5>"
Response.Write "<TR><TH bgcolor=#0000ff><FONT color=#ffffff>Property</TH>"
Response.Write "<TH bgcolor=#0000ff><FONT color=#ffffff>Value</TH></TR>"
For Each f In Rs.Fields
'for every field in the record
Response.Write "<TR><TD><FONT SIZE=1>"
Response.Write f.Name
Response.Write "</TD><TD><FONT SIZE=1>"
'accommodate null and multivalued properties
If Not IsNull(f.Value) Then
If IsArray(f.Value) Then
'a multivalued property
Dim V
For Each V In f.Value
On Error Resume Next
Response.Write(V & "<br>")
Else
On Error Resume Next
Response.Write f.Value
End If
Else
'Field is null
Response.Write "Null"
End If
Response.Write "</TD></TR>"
Response.Write "</TABLE><br><hr><br>"
Rs.MoveNext
Loop
End If
End Function
