Is it possible to directly return the java.sql.ResultSet from Groovy?

Question

I have a Groovy script that is using the groovy.sql.Sql class to communicate with the DB, but some legacy Java code is expecting to receive a java.sql.ResultSet . Is there any way to execute a SELECT query using groovy.sql.Sql and directly return the java.sql.ResultSet ?

Answer 1

Not really. One of the main reasons to use Groovy's Sql is to automatically handle resources (which is why there are methods using closures to interact with the ResultSet , but none that return it -- to ensure they get closed). I'd strongly recommend revisiting why you are passing around references to ResultSet (which could be holding onto server resources) rather than using a POJO/POGO representing those results.

However, if you insist on using ResultSet , and you only need few convenience methods, I guess one option would be to copy those methods into your codebase. As you can see from the source , Sql is a pretty thin wrapper over plain old JDBC. But for what it sounds like you're doing, I question how much value it adds.
