如何在PL/SQL中返回ROWTYPE并在Java中检索它？

DECLARE
  CURSOR emp_cursor IS
    SELECT * FROM employees;

DECLARE
  emp_rec employees%ROWTYPE;
BEGIN
  OPEN emp_cursor;
  FETCH emp_cursor INTO emp_rec;
  CLOSE emp_cursor;
END;

import java.sql.*;

public class RetrieveRowType {
  public static void main(String[] args) {
    try {
      // Establish database connection
      Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe", "username", "password");

      // Create CallableStatement to execute PL/SQL code
      CallableStatement cstmt = conn.prepareCall("{call your_plsql_procedure(?, ?)}");

      // Register OUT parameter to retrieve ROWTYPE
      cstmt.registerOutParameter(1, OracleTypes.STRUCT, "EMPLOYEES_ROWTYPE");

      // Execute PL/SQL code
      cstmt.execute();

      // Retrieve ROWTYPE data
      STRUCT struct = (STRUCT) cstmt.getObject(1);
      Object[] attributes = struct.getAttributes();

      // Process ROWTYPE data
      // ...

      // Close resources
      cstmt.close();
      conn.close();
    } catch (SQLException e) {
      e.printStackTrace();
    }
  }
}
