我需要在具有大写列名称的列上创建分区。但是，Hive会将所有列名称隐式转换为小写。我无法在select *查询中获取数据。我无法将文件夹名称更改为小写。以下是我正在使用的Create查询：
CREATE EXTERNAL TABLE db.ALERT_DS_Hive_Test
PARTITIONED BY (PROC_ID String)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.avro.AvroSerDe'
WITH SERDEPROPERTIES ('casesensitive'='PROC_ID')
STORED AS INPUTFORMAT 'org.apache.hadoop.hive.ql.io.avro.AvroContainerInputFormat'
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.avro.AvroContainerOutputFormat'
LOCATION '/user/sam/hive-test/ALERT_DS.avro/'
TBLPROPERTIES ('avro.schema.url'='/user/sam/hive-test/ALERT_DS.avsc');
