What is the limit of CHAR in SQLLOADER?

Dear Experts,

I am loading a series of files into a table using SQLLOADER. One of the fields in Loader Control File has been defined as CHAR (4096). I wonder about the limit of CHAR in SQLLOADER Control File. May I for example define it as 1 GB? Is it bad for performance since SQLLOADER will have to allocate a huge buffer space for this?

If you have a large string, then you need to define a large CHAR value, the data won't load without doing so.

performance isn't really the consideration, but, as you might expect: large data will take longer than small data.

there is no defined limit, it will be based on the available memory to create the buffer

you can't specify CHAR(1GB)

but you can specify large numbers like

CHAR(1222333444)

which would be over 1 gb
