使用带有列类型的 mongoimport 导入 CSV

Question

Am using mongoimport with defined field type --columnsHaveTypes. When i import the file got an error

Failed: type coercion failure in document #1 for column 'time', could not parse token '2020-09-08T09:41:19.693+0300' to type date>

i used the below command

mongoimport --db main --collection data --type csv --columnsHaveTypes --fields="time.date(2006-01-02),duration.int32(),entry.string()" --file="path\\to\\test.csv"

Answer 1

2020-09-08T09:41:19.693+0300 is not standard representation of date/time so mongoimport cannot parse it.

https://tools.ietf.org/html/rfc3339#section-5.6 defines local offset as

time-numoffset = ("+" / "-") time-hour ":" time-minute

Your string lacks a colon. 2020-09-08T09:41:19.693+03:00 will be parsed correctly.
