How to get sequence of records, from Oracle cursor

[Dan Campbell]

(defn myquery

  [s_id]

    (let 

      [ seq_map_cursor ( exec-raw [ "SELECT  package.function( ? ) key FROM DUAL" [ s_id ] ] :results )

        map_cursor ( into {} seq_map_cursor )

        cursor_rows ( map_cursor :key )

        seq_rows ( resultset-seq cursor_rows )]

        seq_rows ))

Using code similar to the above, the connection keeps getting closed, when I try to convert it to a sequence of rows.  The error is

SQLRecoverableException Closed Statement: getMetaData  oracle.jdbc.driver.OracleResultSetImpl.getMetaData (OracleResultSetImpl.java:168)

, and is happening at the statement 

seq_rows ( resultset-seq cursor_rows )
