cftry

Description

Used with one or more 

cfcatch

 tags. Together, they catch and process exceptions in ColdFusion 

pages. 

Exceptions

 are events that disrupt the normal flow of instructions in a ColdFusion page, 

such as failed database operations, missing include files, and developer-specified events.

Category

Exception handling tags

Syntax

 to include 

try

 and 

catch

 statements that are equivalent to 

the 

cftry

 and 

cfcatch

 tags.

Usage

Within a 

cftry

 block, put the code that might throw an exception, followed by one ore more 

cfcatch

 tags that catch and process exceptions. This tag requires an end tag.

Example

<!--- cftry example, using TagContext to display the tag stack. --->
<h3>cftry Example</h3>
<!--- Open a cftry block. --->
<cftry>

<!--- Note misspelled tablename "employees" as "employeeas". --->
<cfquery name = "TestQuery" dataSource = "cfdocexamples">

SELECT *
FROM EMPLOYEEAS

</cfquery>

<!--- <p>... other processing goes here --->
<!--- specify the type of error for which we search --->
<cfcatch type = "Database">
<!--- the message to display --->

<h3>You've Thrown a Database <b>Error</b></h3>
<cfoutput>

<!--- and the diagnostic message from the ColdFusion server --->
<p>#cfcatch.message#</p>
<p>Caught an exception, type = #CFCATCH.TYPE# </p>
<p>The contents of the tag stack are:</p>
<cfloop index = i from = 1 

to = #ArrayLen(CFCATCH.TAGCONTEXT)#>
