Hive load CSV with commas in quoted fields

Question

I am trying to load a CSV file into a Hive table like so:

CREATE TABLE mytable
(
num1 INT,
text1 STRING,
num2 INT,
text2 STRING
)
ROW FORMAT DELIMITED FIELDS         


        

Answer 1

Add a backward slash in FIELDS TERMINATED BY '\;'

For Example:

CREATE  TABLE demo_table_1_csv
COMMENT 'my_csv_table 1'
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\;'
LINES TERMINATED BY '\n'
STORED AS TEXTFILE
LOCATION 'your_hdfs_path'
AS 
select a.tran_uuid,a.cust_id,a.risk_flag,a.lookback_start_date,a.lookback_end_date,b.scn_name,b.alerted_risk_category,
CASE WHEN (b.activity_id is not null ) THEN 1 ELSE 0 END as Alert_Flag 
FROM scn1_rcc1_agg as a LEFT OUTER JOIN scenario_activity_alert as b ON a.tran_uuid = b.activity_id;

I have tested it, and it worked.
