Question

我是hive的新手，我正在创建一个包含以下属性的表，

CREATE EXTERNAL TABLE EXTTBL_Transactions
(
    TRANSACTION_ID varchar(70) COMMENT 'UniqueID, `Primary Key',
    DEFINITION_ID varchar(70) COMMENT 'Definition, Null Allowed',
    USER_ID varchar(70) COMMENT 'Contact id, Foreign Key',
    PURCHASE_DATETIME Timestamp COMMENT 'Saved dattime, Null Allowed',
    PURCHASE_AMOUNT FLOAT COMMENT 'Sum  value of number of product purchase,Null Allowed',
    INTERACTIONS_ID varchar(70) COMMENT 'Unique interaction id, Foreign Key',
    PRODUCT_DETAILS array<struct<PRODUCT_NAME:varchar(70),PRODUCT_PRICE:FLOAT>> COMMENT 'Product Details'
)
COMMENT 'Transaction details'
PARTITIONED BY (LOAD_DATE DATE)
row format delimited fields terminated by ','
lines terminated by '\n'
collection items terminated by '|'
map keys terminated by ':'
LOCATION 's3a://XXX/XXX//Transactions';

在上面的代码中，我正在为产品详细信息创建一个struct类型数组。我将每个产品细节与'|'分开和'struct'结构元素，但不知何故这会导致错误。

转而回答。

订单应为FIELDS，COLLECTION ITEMS，MAP KEYS，然后是LINES

Hive DDL

row_format
  : DELIMITED [FIELDS TERMINATED BY char [ESCAPED BY char]] [COLLECTION ITEMS TERMINATED BY char]
        [MAP KEYS TERMINATED BY char] [LINES TERMINATED BY char]

Hive错误：编译语句：FAILED：ParseException 15：0在''\ n''附近'collection'处缺少EOF
