16. If you leave the returnvariable attribute named getArtworkRet, you need to change all of the ColdFusion

variables in the HTML code to reflect this change. Instead, it is easier to rename the returnvariable to artwork.

Modify the cfinvoke tag as the following code shows

<cfinvoke

component="CFIDE.gettingstarted.tutorial.art"

method="getArtwork"

returnvariable="artwork">

</cfinvoke>

17. Save and browse the index.cfm page to see that it runs as it did before, when the cfquery tag was in the page.

Figure 78. The final

index.cfm page using the

cfinvoke tag to grab the

information from the

database for display

When you stored the cfquery in the index.cfm page, it was only available to that page. If you wanted to reuse the query

for another page, you would have to create a separate cfquery for the second page. Now that you have created the

CFC, you can use it in other pages by simply using the cfinvoke tag.
