Hello. I am very bad at ASP and use ASPRunner Pro to write ASP pages for me. I have come across a problem however which I cannot figure out. Quite simply on a list page I have six fields, [G1 Title],[G2Title],[G3Title],[G4Title],[G5Title],[G6Title]. Depending on who has logged in however, not all of these fields will contain a value. Each of these has its own column and is only displayed once via a SELECT DISTINCT statement. In other words [G1 Title] for example is either populated or NULL, it can not be both. All that I want to do is get the ASP page not to show an empty column for [G1 Title] if it is null. I only want the columns for [G1 Title] through to [G6 Title] to display if their respective values are not NULL. Could anybody help me with this? I would be extremely grateful.
Con.

The query is just SELECT * FROM Test but I'm not sure if that's what you mean by the code that queries the db.
Many Thanks

@jhardman
Hi Jared
I just wondered if you had had any thoughts on this? It is giving me a real headache.
Thanks
Con
Why don't you try using isnull function.
Example
strValue = ""
if not isnull(rst.fiel d("Column1")) then strValue = rst.field("Colu mn1")

I don't recognize the code at all, it doesn't look like asp to me. What development environment are you using?
Jared
@jhardman
Hi Jared
It is ASPRunner Pro. So far I have come up with...
if IsNull(("G2")) or IsEmpty ("G2") or ("G2")="" or len("G2")>0 then
xt.assign "G2_fieldheader column",false
xt.assign "G2_fieldcolumn ",false
end if
but this just gets rid of the G2 header and its column whether the value for G2 is null or not. It is as if none of the above if conditions actually mean a NULL value in the database.
Con.
@jhardman
This is classic ASP.
isnull is a function (VBscript and Visual Basic the same) that verifies a variable/field for a NULL
 jhardman 3,406
Recognized Expert Specialist @viktorka
no, I recognize isnull, that's fine, what I don't recognize is - # {BEGIN G1_Title_fieldheadercolumn}<TD class=blackshade>{BEGIN G1_Title_fieldheader}<A class=blackshade
-
# {$G1_Title_orderlinkattrs}>G1 Title</A> {END G1_Title_fieldheader}</TD>{END G1_Title_fieldheadercolumn}
This does not look like ASP classic, or ASP.NET. I guess it could just be place-holders for a wysiwyg editor, but this doesn't show how you are connecting to the db.
In asp this code usually looks something like this: - dim objConn, objRS, strQuery
-
set objConn = server.createobject("adodb.connection")
-
objConn.open "DSN=myDSN;UID=myUser;pwd=myPwd"
-
set objRS = server.createobject("adodb.recordset")
-
strQuery = "SELECT * FROM myTable"
-
objRS.open strQuery, objConn
This is the code I'm looking for that queries the db. The code that builds the table is going to look something like this: - <table><tr>
-
<%
-
for each x in objRS.fields
-
response.write "<th>" & x & "</th>" & vbNewLine
-
next %>
-
</tr>
-
<%
-
do until objRS.eof
-
response.write "<tr>"
-
for each x in objRS.fields
-
response.write "<td>" & objRS(x) & "</td>" & vbNewLine
-
next
-
response.write "</tr>"
-
objRS.moveNext
-
loop %>
-
</table>
