How does one convert from a Java resultset to ColdFusion query in Railo?
- by Shawn Grigson
The following works fine in CFMX 7 and CF8, and I'd assume CF9 as well:
<!--- 'conn' is a JDBC connection --->
<cfset stat = conn.createStatement() />
<cfset rs = stat.executeQuery(trim(arguments.sql)) />
<!--- convert this Java resultset to a CF query recordset --->
<cfset queryTable = CreateObject("java", "coldfusion.sql.QueryTable")>
<cfset queryTable.init(rs) >
<cfset query = queryTable.FirstTable() />
This creates a statement using a JDBC driver, executes a query against it, putting it into a java resultset, and then coldfusion.sql.QueryTable is instantiated, passed the Java resulset object, and then queryTable.FirstTable() is called, which returns an actual coldfusion resultset (for cfloop and the like).
The problem comes with a difference in Railo's implementation. Running this code in Railo returns the following error: No matching Constructor for coldfusion.sql.QueryTable(org.sqlite.RS) found.
I've dumped the Railo java object, and don't see init() among the methods. Am I missing something simple? I'd love to get this working in Railo as well.
Please note: I am doing a DSN-less connection to a SQLite db. I understand how to set up a CF datasource. My only hiccup at this point is doing the translation from a Java result set to a Railo query.
