Usage
Use this tag within a
cfcatch
block. This tag is useful in error handling code, if the error handler
cannot handle an error that it catches. For example, if
cfcatch type = "any"
gets a
DATABASE exception, and the code is designed to handle only CFX exceptions, the handler
raises the exceptions again, with details intact, so that a higher-level handler can process the error
information. If you used the
cfthrow
tag, the type and details of the original exception would be
lost.
Example
<h3>cfrethrow Example</h3>
<!--- Rethrow a DATABASE exception. --->

<cfquery name = "GetMessages" dataSource = "cfsnippets">
SELECT *
FROM Messages
</cfquery>
<cfcatch type = "DATABASE">
<!---- If database signalled a 50555 error, ignore; otherwise rethrow
exception. ---->
<cfif cfcatch.sqlstate neq 50555>
<cfrethrow>
</cfif>
</cfcatch>
</cftry>
<cfcatch>
