Jens Geyer updated CASSANDRA-21131:
-----------------------------------
Description:
I'm following the example from the docs, just slightly changed:
https://docs.datastax.com/en/cql-oss/3.x/cql/cql_reference/cqlshCopy.html
{code}
CREATE KEYSPACE cycling WITH REPLICATION = { 'class' :
'NetworkTopologyStrategy', 'datacenter1' : 1 } ;
CREATE TABLE cycling.cyclist_name ( id UUID PRIMARY KEY, lastname text,
firstname text ) ;
INSERT INTO cycling.cyclist_name (id, lastname, firstname)
VALUES (5b6962dd-3f90-4c93-8f61-eabfa4a803e2, 'VOS','Marianne');
INSERT INTO cycling.cyclist_name (id, lastname, firstname)
VALUES (88888888-8888-8888-8888-888888888888, 'V\S','\"Marianne"\');
SELECT * FROM cycling.cyclist_name ;
{code}
This gives:
{code}
id | firstname | lastname
--------------------------------------+----------------+----------
5b6962dd-3f90-4c93-8f61-eabfa4a803e2 | Marianne | VOS
88888888-8888-8888-8888-888888888888 | \\"Marianne"\\ | V\\S
(2 rows)
{code}
Now export to a file, then import from the very same file:
{code}
COPY cycling.cyclist_name TO 'cyclist.csv' WITH HEADER = TRUE ;
TRUNCATE cycling.cyclist_name ;
COPY cycling.cyclist_name FROM 'cyclist.csv' WITH HEADER = TRUE ;
SELECT * FROM cycling.cyclist_name ;
{code}
Now the result is this:
{code}
id | firstname | lastname
--------------------------------------+--------------------+----------
5b6962dd-3f90-4c93-8f61-eabfa4a803e2 | Marianne | VOS
88888888-8888-8888-8888-888888888888 | \\\\"Marianne"\\\\ | V\\\\S
(2 rows)
{code}
I did not change any data in between. Just export and reimport.
