640 Chapter 3: ColdFusion Functions
This function ensures that ColdFusion evaluates the code as follows:
'1', '2', '3'
Example
<h3>PreserveSingleQuotes Example</h3><p>This is a useful function for
creating lists of information to return from a query. In this example,
we pick the list of Centers in Suisun, San Francisco, and San Diego,
using the SQL grammar IN to modify a WHERE clause, rather than looping
through the result set after the query is run.
<cfset List = "'Suisun', 'San Francisco', 'San Diego'">
<cfquery name = "GetCenters" datasource = "cfsnippets">
SELECT Name, Address1, Address2, City, Phone
FROM Centers
WHERE City IN (#PreserveSingleQuotes(List)#)
</cfquery>
<p>We found <cfoutput>#GetCenters.RecordCount#</cfoutput> records.
<cfoutput query = "GetCenters">
<p>#Name#<br>
#Address1#<br>
<cfif Address2 is not "">#Address2#
</cfif>
#City#<br>
#Phone#<br>
</cfoutput>
