Multiple-level of delimiters works as the following by default:
The first level (fields delimiters) will be \001 (^A, ascii code 1). Each level of struct and array take an additional field delimitor following (\002, etc). Each level of map takes 2 levels of additional field deimitor. So it will be: s1.name ^B s1.age ^A a1[0].x ^C a2[0].y ^B a1[1].x ^C a2[1].y ^A b1.key1 ^C b1.value1[0] ^D b1.value1[1] ^B b1.key2 ^C b1.value2[0] ^D b1.value2[1] Zheng On Fri, Mar 19, 2010 at 6:07 PM, Dilip Joseph <dilip.antony.jos...@gmail.com> wrote: > Hello, > > What are the delimiters for data to be loaded into a table with nested > arrays, structs, maps etc?
