CFLOOP: LOOPING OVER A QUERY |
Description
A loop over a query executes for each record in a query record set. The results are similar to those of the cfoutput tag. During each iteration, the columns of the current row are available for output. The cfloop tag loops over tags that cannot be used within a cfoutput tag.
Syntax
    <cfloop
       query = "query_name"
       startRow = "row_num"
       endRow = "row_num">
    </cfloop>

Example
This example shows a cfloop looping over a query the same way as a cfoutput tag that uses the query attribute:
    <cfquery name = "MessageRecords"
       dataSource = "cfsnippets">
          SELECT * FROM Messages
    </cfquery>
    <cfloop query = "MessageRecords">
       <cfoutput>#Message_ID#</cfoutput><br>
    </cfloop>
The cfloop tag also iterates over a record set with dynamic start and stop points. This gets the next n sets of records from a query. This example loops from the 10th through the 20th record returned by MyQuery:
    <cfset Start = 10>
    <cfset End = 20>
    <cfloop query = "MyQuery"
       startRow = "#Start#"
       endRow = "#End#">
       <cfoutput>#MyQuery.MyColName#</cfoutput><br>
    </cfloop>
The loop stops when there are no more records, or when the current record index is greater than the value of the endRow attribute.
The advantage of looping over a query is that you can use CFML tags that are not allowed in a cfoutput tag. The following example combines the pages that are returned by a query of a list of page names into one document, using the cfinclude tag.
    <cfquery name = "GetTemplate"
       dataSource = "Library"
       maxRows = "5">
       SELECT    TemplateName
       FROM Templates
    </cfquery>
    <cfloop query = "TemplateName">
       <cfinclude template = "#TemplateName#">
    </cfloop>
