Here's an alternate method for doing the same thing, when you use your
CFPROCPARAM or CFQUERYPARAM tags, courtesy of Dan Switzer:
"
I found a little tip that save me a few lines of code and thought I'd share
it. You may already be doing this, but a function I rarely use is the
YesNoFormat() function. However, I recently found a neat little place to use
it.
When passing a parameter into a stored procedure via the <CFPROCPARAM> tag,
you have the option to specify whether or not to pass a value or pass the
value as null. Using the YesNoFormat() you can now insert a value (if there
is one) or pass null is the string is blank. This is very useful for date
fields.
For example:
<CFPROCPARAM TYPE="In" CFSQLTYPE="CF_SQL_TIMESTAMP"
DBVARNAME="@ExpirationDate" VALUE="#ExpirationDate#" NULL="#YesNoFormat(NOT
Len(ExpirationDate))#">
This will insert the value in the field "ExpirationDate" as long as the
string isn't empty. If it's empty, the stored procedure will receive a null
value."
