mongoDB mongoimport upsert -

-

i'm trying bulk update following

mongoimport -d my_db -c db_collection -upsertfields email ~/desktop/update_list.csv

the csv i'm trying import looks this. 

email, full_name stack@overflow.com,stackoverflow mongo@db.com,mongodb

it should check email column query arg , update full name accordingly. however, none imported, encountered errors.

exception:failure parsing json string near: abc@sa abc@sasa.com,abc imported 0 objects encountered 99398 errors

where problem? how should doing it?

your mongoimport command missing --upsert option, needed in combination --upsertfields. try:

mongoimport -d my_db -c db_collection --upsert --upsertfields email ~/desktop/update_list.csv
