使用新行字符redshift将数据卸载到s3

Question

i am trying to export table from redshift to s3 using unload command command :

unload ('SELECT * FROM table where id = 4') TO 's3://path/temp/table1'
 credentials 'aws_access_key_id="ahsvdgsfadhsagdffjh;aws_secret_access_key=ahgsdasdhgsahdgsahdgsahdgsahgsa' delimiter '|' NULL
AS
'\\N' escape;

one of the field in my table contains new line so the csv generated breaks into two lines

is there any way to replace new line to \\n or to add a end of line character

Answer 1

You should be removing escape , and just try ADDQUOTE Option, it will produce correct CSV. As "" will instruct your CSV reader to treat \\n as verbiage rather than newline .

UNLOAD ('SELECT * FROM table where id = 4') 
TO 's3://path/temp/table1'
credentials aws_access_key_id="ahsvdgsfadhsagdffjh;
    aws_secret_access_key=ahgsdasdhgsahdgsahdgsahdgsahgsa' 
delimiter '|' 
NULL AS '\\N' ADDQUOTE;
