创建 Athena 表时输入不匹配错误

Question

Getting the following error,

line 1:8: mismatched input 'EXTERNAL'. Expecting: 'OR', 'SCHEMA', 'TABLE', 'VIEW'

when creating an Athena table with the following command,

CREATE EXTERNAL TABLE IF NOT EXISTS 'abcd_123' (Item:struct<Id:struct<S:string>>)
ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe'
WITH SERDEPROPERTIES ('ignore.malformed.json' = 'true')
LOCATION 's3://mybucket'

I've gone through other Q&A's and none of the answers have helped me - any points as to where the error might be here ?

Answer 1

Try putting a space between Item and struct instead of a colon, like so

CREATE EXTERNAL TABLE IF NOT EXISTS 'abcd_123' (
    Item struct<
        Id:struct<
            S:string
        >
    >
)
ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe'
WITH SERDEPROPERTIES ('ignore.malformed.json' = 'true')
LOCATION 's3://mybucket'

This is taken from the AWS Athena docs . I believe the colon is only required between fields of structs and their types, not column names and their types.

CREATE EXTERNAL TABLE IF NOT EXISTS cloudfront_logs (
    `Date` Date,
    Time STRING,
    Location STRING,
    Bytes INT,
    RequestIP STRING,
    ...
