Hi,
My database user has just decided that a recent text field in my database needs to be numeric so that some calculations can be run. I've changed it to a double so I can keep the point formatting (ie. 4.1).
I have changed the data types and altered my variables to insert numbers. I have added a default value of 0 to new records added to the database.
Howevern, some of the existing records have a null field in this changed column.
CF can display them but won't update the field without erroring out if the field is left blank. - PowerRating = <cfif IsDefined("form.PowerRating") AND #form.PowerRating# NEQ "">
-
#form.PowerRating#
-
<cfelse>
-
NULL
-
</cfif>,
Any idea what I am doing wrong?
Thanks
Neil

What's the error message? Have the NULL values in the existing fields been set by the query or the default used to be null?
@acoder
It's a basic sytnx error:
ODBC Error Code = 37000 (Syntax error or access violation)
[Microsoft][ODBC Microsoft Access Driver] Syntax error in UPDATE statement.
The null values are set by the query.
This is the code that adds a new record: - <cfif IsDefined("form.PowerRating") AND #form.PowerRating# NEQ "">
-
#form.PowerRating#
-
<cfelse>
-
NULL
-
</cfif>,
This is the code that updates it if their is a change: - PowerRating = <cfif IsDefined("form.PowerRating")>
-
<cfif #form.PowerRating# NEQ "">
-
<cfset PowerRating = #form.PowerRating#>
-
<cfelse>
-
NULL
-
</cfif>
..which works if the valeu is NULL, but not if it has retrieved any other value.

The following code: - PowerRating = <cfif IsDefined("form.PowerRating")>
-
<cfif #form.PowerRating# NEQ "">
-
<cfset PowerRating = #form.PowerRating#>
-
<cfelse>
-
NULL
would result in the output "PowerRatin g = " when there's a value because you've set a variable but you haven't output anything. Your original code would work.

Just a point to bear in mind: in queries where you accept user input as values, you should use cfqueryparam to insert/update values in the database.
No problem - are there any tutorials on using it?

Yes, there's a few. Here's one from the horse's mouth.

Hi
Some days ago I posted a problem with a query.
Thaks to Dave and John, I got a little closer to a solution.
Their suggestion was a solution to my problem as I stated it, but the real
problem is a bit more complicated, so I have to expand the original problem
a bit.
The query has to handle unknown number of departments, and a date interval.
I want:

Hi,
I have the following SQL statement which is pulling a few details from
a database. As you can see, there is only the one table from which i
am creating a temporary copy.
The reason I do this is because in the table i only have the 'standIn'
listed by integer and i want to return the 'standIn' by name.
I hope this is clear enough.

I need a trigger (well, I don't *need* one, but it would be optimal!)

Is there any alternative? I could write it in laborious code in the

I've created an ASP application which uses an Access database.
I've created an outer join query, but for some reason the "Property_Def"
column is not aligning with the "ESPN" column. They should be aligned on
the ESPI common columns.
In this attached image, the first lines ESPI of 010471 "ADJUSTABILITY"
which should line up with the "Property_Def" column that says "An indication
of whether or not the item is adjustable".

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