創建hive表時（分區表、內外表都適用），遇到雙符號的切分符怎麼辦，比如：||

兩個字段的例子 

# 1. 建表
create  EXTERNAL table b(
id double,
name string)
PARTITIONED BY (ds STRING) 
row format serde 'org.apache.hadoop.hive.serde2.RegexSerDe'
with serdeproperties(
'input.regex'='(.*)\\|\\|(.*)',
'output.format.string'='%1$s %2$s %3$s')
stored as textfile;

# 2. 加載數據
hive> load data local inpath '/root/a' into table b partition (ds='2020-02-02');

# 3. 查看數據
hive> select * from b;
OK

很多字段的例子 （16個字段，需要切15次）

注意：一行數據中有16個分隔符就要在‘input.regex’ = ‘切15次’ 

切分符是其他的話只需把||換成其他即可
