export csv, use ',' as split

[kentkong_work <ke...@163.com>]

hi here,
   I create a table like this and put a lot data into it.
   then I export query result into csv file like this:
    hive -e myquery >> result.csv

   but the csv uses tab as split.
   how to make hive use ','? thanks!

CREATE TABLE if not exists upload_users(
  username string, 
  mobile string, 
  id_type string, 
  id_no string, 
  email string, 
  address string, 
  validate_time string
) partitioned by (fileid string) 
row format delimited fields terminated by "\,";

hive create table is different than the hive query output,

hive by default uses tab as output column separator on console. if you want
to change to csv, why don't you just use sed and replace tab with ","

if you want a csv generated out of the query itself then create a temporary
external table with "," as separator and then load data using your query .
Its a long route.

Wait for sometime so that others can reply with better suggestion if mines
are not suitable for you

Re: export csv, use ',' as split

Hive does not have a output delimiter specifier yet (not sure if 0.11.x may have it)

But for now please try the following

hive -e myquery | sed 's/\t/,/g' >> result.csv

Good luck
