优化SQL SELECT * FROM pbiweb_pbi_user_of_offering WHERE role_id = '437-00024678' and offering_id = '22188417' AND batchno = SELECT MAX(batchno) FROM pbiweb_pbi_user_of_offering WHERE role_id = '437-00024678' and offering _id = '22188417') ORDER BY LAST_UPDATE_DATE ASC;

可以考虑优化这条 SQL 语句，以提高查询效率。在这个 SQL 语句中，有一个子查询，可以使用 JOIN 语句来代替子查询，从而减少查询次数，提高查询性能。以下是优化后的 SQL 语句：

SELECT *
FROM pbiweb_pbi_user_of_offering uoo
JOIN (
    SELECT MAX(batchno) AS max_batchno
    FROM pbiweb_pbi_user_of_offering
    WHERE role_id = '437-00024678' AND offering_id = '22188417'
) uo ON uoo.batchno = uo.max_batchno
WHERE uoo.role_id = '437-00024678' AND uoo.offering_id = '22188417'
ORDER BY uoo.LAST_UPDATE_DATE ASC;

优化后的 SQL 语句使用了 JOIN 语句来代替子查询。它将子查询查询出的最大 batchno 作为一个临时表，通过 JOIN 语句和原表进行关联，从而得到符合条件的记录。这样一来，查询次数就减少了，查询效率也得到了提高。

nsert overwrite table ldleda_rgm_ld.pbi_oms_promo_msppi partition(pt_creat_dt) select *,creat_dt from ldleda_rgm_ld.pbi1_oms_final

这是一个 HiveQL 的语句，它的作用是将 ldleda_rgm_ld.pbi1_oms_final 表的数据插入到 ldleda_rgm_ld.pbi_oms_promo_msppi 表中，并且按照 creat_dt 字段的值进行分区，即每个分区对应一个 creat_dt 值。在执行此语句之前，需要先创建好 pbi_oms_promo_msppi 表并定义好分区。

这是一个Python中的错误信息，看起来你在使用一个名为pybi的模块时出现了问题。错误信息中提到了jinja2和PackageLoader，这可能是因为你没有正确安装或配置这些模块。你可以尝试重新安装pybi模块或安装jinja2模块以解决这个问题。如果问题仍然存在，你可以在相关的Python论坛或社区中寻求帮助。
