I am trying to insert a .csv file into a database with unix linebreaks. The command I am running is:
BULK INSERT table_name
FROM \'C:\\file.csv\'
WITH
(
It comes down to this. Unix uses LF (ctrl-J), MS-DOS/Windows uses CR/LF (ctrl-M/Ctrl-J).
When you use '\n' on Unix, it gets translated to a LF character. On MS-DOS/Windows it gets translated to CR/LF. When the your import runs on the Unix formatted file, it sees only a LF. Hence, its often easier to run the file through unix2dos first. But as you said in you original question, you don't want to do this (I'll assume there is a good reason why you can't).
Why can't you do:
(ROWTERMINATOR = CHAR(10))
Probably because when the SQL code is being parsed, it is not replacing the char(10) with the LF character (because it's already encased in single-quotes). Or perhaps its being interpreted as:
(ROWTERMINATOR =
)
What happens when you echo out the contents of @bulk_cmd?
