Hive Select 选择语句排除一列或多列

有时候我们需要几乎所有的列，但是不包括分区列或其中的某些列，比如分区列要放最后，我们要在之前插入新列并插入新的数据，这时候排除一列或者多列的 select 语句就十分有用了

排除num列

set hive.support.quoted.identifiers=none;
select
`(num)?+.+`
from
    (select 
    row_number() over (partition by uid order by pay_time asc) as num
    ,*
    from order) first_order
where num = 1;

排除num和uid列 

set hive.support.quoted.identifiers=none;
select
`(num|uid)?+.+`
from
    (select 
    row_number() over (partition by uid order by pay_time asc) as num
    ,*
    from order) first_order
where num = 1;

上面的 set hive.support.quoted.identifiers=none; 可以替换操作为：

在 'hive-site.xml' 中添加以下配置，

hive.support.quoted.identifiers=none
