Looping Columns In Coldfusion Along With Values In Correct Order

Instead of hardcoding the columns from a query into a table I prefer to do it dynamically. This is code I tweaked from another source. What I want to do is not only get the Columns

Solution 1:

Something I learned from other people's answers on these forums is that ColdFusion has a function called getColumnList(). It returns an array of the column names in the order they appear. I just ran this code to verify it.

<cfquery name="x" datasource="burns">
select 1 b, 2 a
from dual
</cfquery>
<cfdump var="#x.getcolumnlist()#" metainfo="no">

It returned an array showing b, then a.

For displaying your column headers, you simply loop through this array. Displaying the data would be slightly more complicated. I would do something like this:

<cfoutput query="q1">
<cfloop array="#q1.getcolumnlist()#" index = "arrayElement">
#q1[arrayElement][currentrow]#
closing tags

Solution 2:

This answer seems too obvious to be the answer to your requirement, but I can't think what else you might mean. One loops over a recordset via the <cfloop> tag:

<cfloop query="showDeletedData"><!--- loop rows--->
    <cfloop array="#employeemeta#" index="col"><!--- loop columns--->
        <cfoutput>#showDeletedData[col][currentRow]#</cfoutput><!--- output value for the row/column --->
    </cfloop>
</cfloop>

Is that what you're asking?
