Chapter 8: Debugging and Error Handling 95
Note For cases when the error handler is not able to successfully handle the
thrown error, use the CFRETHROW tag within a <CFCATCH> block.
<CFTRY>
... Add code here ...
<CFCATCH TYPE="
exception type 1">
... Add exception processing code here ...
</CFCATCH>
<CFCATCH TYPE="
exception type 2">
... Add exception processing code here ...
</CFCATCH>
<CFCATCH TYPE="Any">
... Add exception processing code here ...
</CFCATCH>
</CFTRY>
To catch errors in a single problematic SQL statement, for example, you might narrow
the focus by using a CFTRY block with a CFCATCH TYPE="Database" tag, outputting
the CFCATCH.State information as well.
Note Do not attempt to enclose an entire application in a CFTRY block by
putting the CFTRY tag in Application.cfm because you can’t be sure that
there will be a matching CFTRY end tag.
See the CFML Language Reference for information on the CFTRY, CFCATCH,
CFRETHROW, and CFTHROW tags.
Types of recoverable exceptions supported
ColdFusion Server supports several types of recoverable exceptions. Use the TYPE
attribute in the CFCATCH tag to determine which type of exception to catch.
