COLDFUSION 9 APPLICATIONS

The CFML Programming Language

ColdFusion behavior is less straightforward, however, when you use the query column references myQuery.Firstname 
and myQuery["Firstname"] without using an array index. The two reference formats produce different results. 

If you reference myQuery.Firstname, ColdFusion automatically converts it to the first row in the column. For example, 
the following lines print the word "ben":

 

 

 

 

<cfset myCol = myQuery.Firstname >  

 

<cfoutput>#mycol#</cfoutput>

But the following lines display an error message:

 

 

 

 

<cfset myCol = myQuery.Firstname >  

 

<cfoutput>#mycol[1]#</cfoutput><br>

If you reference 

Query["Firstname"]

, ColdFusion does not automatically convert it to the first row of the column. 

For example, the following line results in an error message indicating that ColdFusion cannot convert a complex type 
to a simple value:

 

 

 

 

<cfoutput> #myQuery['Firstname']# </cfoutput><br>

Similarly, the following lines print the name "marjorie", the value of the second row in the column:

 

 

 

 

<cfset myCol = myQuery["Firstname"]>  

 

<cfoutput>#mycol[2]#</cfoutput><br>

However, when you make an assignment that requires a simple value, ColdFusion automatically converts the query 
column to the value of the first row. For example, the following lines display the name "ben" twice:

 

 

 

 

<cfoutput> #myQuery.Firstname# </cfoutput><br>  

 

<cfset myVar= myQuery['Firstname']>  

 

<cfoutput> #myVar# </cfoutput><br>

Using periods in variable references

ColdFusion uses the period (.) to separate elements of a complex variable such as a structure, query, XML document 
object, or external object, as in MyStruct.KeyName. A period also separates a variable scope identifier from the variable 
name, as in Variables.myVariable or CGI.HTTP_COOKIE.

With the exception of Cookie and Client scope variables, which must always be simple variable types, you cannot 
normally include periods in simple variable names. However, ColdFusion makes some exceptions that accommodate 
legacy and third-party code that does not conform to this requirement.

and WDDX

” on page  1058.

Understanding variables and periods

The following descriptions use a sample variable named MyVar.a.b to explain how ColdFusion uses periods when 
getting and setting the variable value.

Getting a variable

ColdFusion can correctly get variable values even if the variable name includes a period. For example, the following 
set of steps shows how ColdFusion gets MyVar.a.b, as in 

<cfset Var2 = myVar.a.b>

 or 

IsDefined(myVar.a.b

):

1

Looks for myVar in an internal table of names (the symbol table).

2

If myVar is the name of a complex object, including a scope, looks for an element named 

a

 in the object.

If myVar is not the name of a complex object, checks whether myVar.a is the name of a complex object and skips 
step 3.
