CREATE EXTERNAL table dev_vlh0_pricing_engine.Client(UniqueID STRING)
STORED AS PARQUET
LOCATION '/dev/05510/app/VLH0/data/PE_decision_records_DEV/Client';

Insert Overwrite table dev_vlh0_pricing_engine.Client
SELECT ODMRequest.header.UniqueID from dev_vlh0_pricing_engine.TA1;

已经创建了一个外部表，因为仅根据所创建的主表为少数字段创建了另一个表。

CREATE EXTERNAL table dev_vlh0_pricing_engine.TABLE_Parquetstruct5
(ODMRequest STRUCT< header:STRUCT<UniqueID:STRING,DateTime:TIMESTAMP,SourceID:STRING,ChannelID:STRING,ProcessID:STRING>,Application:STRUCT<createdOn:string,clients:ARRAY<STRUCT<SRF:string,IsStaff:string>>>>,
ODMResponse STRUCT<championChallenger:string,PricingDecisionID:string>)STORED AS PARQUET 
LOCATION '/dev/05510/app/VLH0/data/PE_decision_records_DEV/Testparquet';

表客户端应仅显示详细信息唯一ID

创建外部表为选择问题
