yes it shows the proper values when I query the csv file. CTAS query csv to parquet : Create table `dfs`.`tmp`.`publicholiday.parquet` AS SELECT CASE WHEN `Day` = '' THEN CAST(NULL AS VARCHAR(100)) ELSE CAST(`Day` AS VARCHAR(100)) END AS `Day`, CASE WHEN `Date` = '' THEN CAST(NULL AS VARCHAR(100)) ELSE CAST(`Date` AS VARCHAR(100)) END AS `Date`, CASE WHEN `Area` = '' THEN CAST(NULL AS VARCHAR(100)) ELSE CAST(`Area` AS VARCHAR(100)) END AS `Area` FROM TABLE (dfs.`PublicHoliday.csv`(type => 'text',fieldDelimiter => ',', extractHeader => true))
