这是一条SQL语句,它的作用是将多个表中符合条件的数据合并到一个表中,并覆盖原有的数据。具体来说,它将 bss 数据库中表 tb_bil_red_list_550_${month_no_pre} 到 tb_bil_red_list_566_${month_no_pre} 中满足条件的数据合并到表 tb_bil_red_list_total_all 中,并覆盖原有的数据。其中,${month_no_pre} 是一个变量,代表某个月份的前缀。这条语句执行的前提是您有权限访问 bss 数据库和这些表,并且变量 ${month_no_pre} 已经被正确设置。

insert overwrite table tb_bil_red_list_all select * from (select *,ROW_NUMBER () over(PARTITION by obj_id order by exp_date desc,eff_date asc) n from tb_bil_red_list_total_all) a where n=1
这是一条SQL语句,它的作用是将tb_bil_red_list_total_all表中每个obj_id分组后,按照exp_date降序、eff_date升序排序,取出每组中n=1的记录,并将其插入到tb_bil_red_list_all表中,覆盖原有的数据。简单来说,就是从一个表中找出每个obj_id对应的最新记录,并将其存储到另一个表中。
insert overwrite table dim.prod_designcase_fact partition (month)
Unfortunately, as an AI language model, I do not have access to your database or table structure, so I cannot provide a complete and accurate answer to your question. However, I can provide you with a general explanation of the command you provided.
The command "insert overwrite table dim.prod_designcase_fact partition (month)" is an SQL statement that is used to insert data into a table and overwrite any existing data in the table. The "dim.prod_designcase_fact" is the name of the table, and "partition (month)" specifies that the data will be inserted into a specific partition based on the value of the "month" column.
Without more information about your specific database and table structure, it is difficult to provide a more detailed explanation or example. It is important to ensure that you have the necessary permissions and access rights to execute this command and that you fully understand the implications of overwriting data in a table.
