Hi,

I'm a low level coder, so please bear with me.

I have a table in a database with a field called 'company' I want to display
the value of that field in my application when there is a value in the
database, and display 'N/A' in the app when there is no value. The code I
have is as follows, and as you've guessed, it doesnt work.

company = rs("company") (record set has been established and pulls data down
ok)

If company = null Then
company = "N/A"
End IF

<%=company%>

Any assitance would be great.

Thanks in advance

<%
company = rs("company") & ""
If company = "" Then
company = "N/A"
End If
%>

<%=company%>

Try that.

Ray at work

If company IS null Then
...
End If

Just to expand on Ray's answer:
Nothing can ever be equal to (=) Null. "Null" means that the value is
"unknown", so the result of any comparison or calculation involving Null
will result in Null. The only exception to this rule in vbscript is
concatenation (&): when you concatenate Null to a string, you get that
string returned. Ray's solution takes advantage of that exception.

In vbscript, you can use the IsNull() function to test whether a value is
null or not. For more information see:

In SQL, you can use the Is operator to test whether a column or variable
contains Null:
WHERE somecolumn Is Null
