Blank Coldfusion errors on Query of Queries using like clause

Nate Admin — Fri, 16 Jan 2009 01:40:34 +0000

[Macromedia][SQLServer JDBC Driver]Value can not be converted to requested type.

If you have a string column that contains a null value, this occurs. You have to add a check for the null first. Note that the like clause is also case sensitive for query of queries.

Breaks:

SELECT * FROM myTable
WHERE 1=1
AND LOWER(name) LIKE

Works:

SELECT * FROM myTable
WHERE 1=1
AND name is not null AND LOWER(name) LIKE

Coldfusion cfqueryparam of type decimal, cf_sql_decimal, requires the scale argument

Nate Admin — Wed, 08 Oct 2008 16:23:46 +0000

I learned the hard way that if you don’t include the scale attribute in the cf_sql_decimal cfqueryparam tag, then your decimal gets rounded to the nearest whole number. IF this isn’t what is intended, this can really bite. Make sure you specify the scale with the scale argument to make you cfqueryparam as accurate as intended.

Throw errors in a cfscript and try catch in cfscript
Nate Admin — Wed, 02 Jul 2008 16:51:41 +0000
You CAN’T throw an error or errors from a cfscript without defining your own throw function. But this is pretty easy to do. Somewhere else in your code, just write a 
See the example code below. Note the interesting syntax for catching in a cfscript where you do catch(ERRORTYPE CFCATCHVARIABLE). So catch(database e), catch(any e) would be some common ones. And then you could access e.Message, e.Detail, etc.
try

{

     //nothing below the throw would execute in this example.

     //But I left the rest for syntax reference.

     somethingWrong=true;

     if(somethingWrong){

          throw("ExampleErrorType","Example Error message.");

}

     //save the reactor record without interfering with custom transaction

     template1.save(useTransaction=false);

}

catch (database err)

{

     //if the save fails and the error is a database error, return the error detail.

     //otherwise this error will need to be caught by the code calling this code.

     return  err.Detail;

}
If you want to do a rethrow, the following article has a great example.

An error occured while Parsing an XML document.:Content is not allowed in prolog.
This mean coldspring cannot find the xml of an expandPath(), or a config argument.  On the init of a bean, the line in the init of the cfc was


the arguemtns.environmentXML came from the xml coldspring config,


			/environment/thecompany/settings.xml

		
My mappings on the server to the path were wrong.
C:\HOMEDEV\RESOURCES\localEnvironment\heritagemakers

should have been

C:\HOMEDEV\RESOURCES\localEnvironment

Error Loading: bean_C15CD3571617EEF37B66D49B00F832B8, The cause of this exception was: java.io.FileNotFoundException: D:\HM\Branches\RanaRana\Coldspring\aop\framework\tmp\bean_C15CD3571617EEF37B66D49B00F832B8.cfc (The system cannot find the path specified).
Weird. You have to manually create the tmp folder under yourColspringInstall\aop\framework

Get the domain entered from the request. Coldfusion CGI.HTTP_HOST
Nate Admin — Wed, 18 Jun 2008 15:40:11 +0000
Use CGI.HTTP_HOST
Issue: mydomain.com gets load-balanced and uses multiple servers. CGI.SERVER_NAME will not return ‘mydomain’ but will return ’sever1′ or ’server2′ etc. 
I want to check the request URL, and if it does not include www, re-locate to www.mydomain/pagerequested?event=eventrequested
