using access 2000. Have a form based on a couple of controls, it
finds the last used Inquiry number in a table. So it finds the
highest Inquiry number for the "Office" , "Company" and "YearStamp"
selected by the user.
Code below:
=IIf(IsNull(DMa x("[Inquiry Number]","Inquiry" ,"[Office] = '" &
[Form]![Office Code] & "' and" & "[Company] = '" & [Form]![Company
Code] & "' and " & "[YearStamp] = " &
[Form]![Year])),0,DMax("[Inquiry Number]","Inquiry" ,"[Office] = '" &
[Form]![Office Code] & "' and" & "[Company] = '" & [Form]![Company
Code] & "' and " & "[YearStamp] = " & [Form]![Year]))
I use to just use the DMax but had to change it to an IIF because of
nulls. But this code simply places #ERROR in the control when it is
null.
Am I doing something wrong? Wait obviously I am doing something
wrong. Can someone lead me in the right direction.
I'm doing this iif statement in the control source property. 2 2529
just off the cuff, have you tried using NZ(dmax etc.) instead of the iif

how about using NZ(<<expression >>) which will convert the Null value
to zero for you? This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hi all,
I would like to get people's opinion about executing SQL statements in C#
(or any other .NET language really). I used to create my SQL statement by
building a string and replacing single quote with two single quotes.
Sometimes, I used SqlParameter. Maybe, I'm a bit lazy when I build the SQL
string. Should I always use SqlParameters? What are the
advantages/disadvantages between building SQL string and using SqlParameter?

Hi
I am building a very simple data entry system with many forms and

When I leave any part of the form empty (it allows nulls) it seems to

I have written a script to test for empty textboxes and insert DB.NULL
which is fine but when I want to load the data back into the form

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
