# Proposed changes
Issue Number: close #xxx
External catalog table column names in doris are all in lower case, while
iceberg table or spark-sql created hive table may contain upper case column
name, which will case empty query result. This pr is to fix this bug.
For parquet file, transfer all column names to lower case while parse
parquet metadata.
For orc file, store the origin column names and lower case column names in
two vectors, use the suitable names in different cases.
Describe your changes.
