ROW FORMAT DELIMITED 分隔符设置开始语句

FIELDS TERMINATED BY：设置字段与字段之间的分隔符

COLLECTION ITEMS TERMINATED BY：设置一个复杂类型（array,struct)字段的各个item之间的分隔符

MAP KEYS TERMINATED BY：设置一个复杂类型(Map)字段的key value之间的分隔符

LINES TERMINATED BY：设置行与行之间的分隔符

例：

Hive> create table t(id struct<id1:int,id2:int,id3:int>,name array<string>,xx map<int,string>)
    > row format delimited
    > fields terminated by '\t'
    > collection items terminated by ','
    > map keys terminated by ':'
    > lines terminated by '\n';
OK
Time taken: 0.287 seconds

ROW FORMAT DELIMITED 必须在其它分隔设置之前，也就是分隔符设置语句的最前

LINES TERMINATED BY必须在其它分隔设置之后，也就是分隔符设置语句的最后，否则会报错

hive> create table t (id struct<id1:int,id2:int,id3:int>,name array<string>,xx map<int,string>) 
    > row format delimited
    > fields terminated by '\t'
    > lines terminated by '\n'
    > collection items terminated by ','
    > map keys terminated by ':';
FAILED: ParseException line 5:0 missing EOF at 'collection' near ''\n''

for example:

编辑本地文件：f.txt 内容为：1,2     1,2,3,4,5       1:value_1,2:value_2

导入本地文件：load data local inpath '/f.txt' into table t;

查询表数据：select * from t;

{"id1":1,"id2":2}       ["1","2","3","4","5"]   {1:"value_1",2:"value_2"}
