Java 调用 MySQL 存储过程并获得返回值

 
private void empsInDept(Connection myConnect,int deptId) throws SQLException {
   
  CallableStatement cStmt = myConnect.prepareCall("{CALL sp_emps_in_dept(?)}");
  cStmt.setInt(1,deptId);
  cStmt.execute();
  ResultSet rs1 = cStmt.getResultSet();
  while (rs1.next()) {
       System.out.println(rs1.getString("department_name") + " "
         + rs1.getString("location"));
  }
  rs1.close();
 
  /* process second result set */
  if (cStmt.getMoreResults()) {
       ResultSet rs2 = cStmt.getResultSet();
       while (rs2.next()) {
        System.out.println(rs2.getInt(1) + " " + rs2.getString(2) + " "
              + rs2.getString(3));
       }
       rs2.close();
  }
  cStmt.close();
}
