Looks like it only supports csv, not tsv.

Alexey Milovidov · Answer 2 · Mon Jun 27 2022 10:20:10 GMT+0800 (China Standard Time)

But csv import also failed:

buntu@ip-172-31-13-55:~$ psql -U crate -h localhost --no-password -t -c '\timing' -c "COPY hits FROM 'file:///$(pwd)/hits.csv'"
Timing is on.
COPY 0

Hi @alexey-milovidov,

you might want to use the RETURN SUMMARY option (https://crate.io/docs/crate/reference/en/4.8/sql/statements/copy-from.html#return-summary)

to see where the problem with your COPY statement resides

Georg Traar · Answer 4 · Mon Jun 27 2022 15:36:03 GMT+0800 (China Standard Time)

Importing .tsv is possible with using the csv format with the following options (delimiter = e'\t', format='csv')

% touch test.tsv                                                                     
% echo "a\tb\n1\t2" >> test.tsv                                                                        

% crash -c "CREATE TABLE tsv (a INT, b INT)"
CREATE OK, 1 row affected  (1.776 sec)

% crash -c "COPY tsv FROM '/Users/gtraar/test.tsv' WITH (delimiter = e'\t', format='csv') RETURN 
COPY 1 row in set (0.069 sec)

Georg Traar · Answer 5 · Mon Jun 27 2022 16:41:35 GMT+0800 (China Standard Time)

To directly import the hits file, use:

COPY hits
FROM 'https://datasets.clickhouse.com/hits_compatible/hits.tsv.gz'
WITH (
  "delimiter"=e'\t',
  "format"='csv',
  "compression"='gzip',
  "header"=false,
  "empty_string_as_null" = false)
RETURN SUMMARY;

Alexey Milovidov · Answer 6 · Fri Jul 01 2022 08:05:14 GMT+0800 (China Standard Time)

Thank you! I will try that.

Alexey Milovidov · Answer 7 · Fri Jul 01 2022 21:24:09 GMT+0800 (China Standard Time)

Ok. If I try to load TSV as in the example above, it gets confused when the value started with a quote:

{"Missing closing quote for value\n at [Source: UNKNOWN; line: 1, column: 1069]":{"count":1,"line_numbers":[93557187]}

Maybe better if I will use CSV. Or another parameter is needed.

PS. Kudos for the error messages, they are really great.

Alexey Milovidov · Answer 8 · Fri Jul 01 2022 21:25:16 GMT+0800 (China Standard Time)

Also one minor issue:

"Cannot cast value `g` to type `char`":{"count":14512774,"line_numbers":[831,837,841,845,4081,4092,7276,7324,9899,9902,832,834,836,840,843,4086,4087,4090,9411,9556,9898,833,835,838,839,844,846,847,4084,842,7281,24149,28856,24139,24147,24155,24135,24137,24141,24143,24146,24151,24153,24131,24134,86522,106486,139464,164706,168419]}

It is unclear to me, but hopefully I will figure it out.

@alexey-milovidov Proper support for char was just added to master branch with: #12672

You can use string for now, to overcome the import issue.

Alexey Milovidov · Answer 10 · Sat Jul 02 2022 18:22:59 GMT+0800 (China Standard Time)

I've successfully loaded the data (except for one record), and the problem is solved.
