I have many GB of data stored in PostgreSQL database and i need those to be imported into the MongoDB. I did this using CSV export and mongoimport.
There are columns like this ‘2011-06-25’ in that CSV and it has been imported as string, not as MongoDate, so i cannot effectively search by date.
I’ve found this : http://www.mongodb.org/display/DOCS/Import+Export+Tools#ImportExportTools-Example%3AImportingInterestingTypes
but the example says, i need to use JSON structure for the file. Do i really need to export JSON file from PostgreSQL?
If i do – how?
If i don’t, how to export “MongoDate” through CSV?
Your options:
import the stuff as CSV and convert the data after the import to Date() (either using the mongo console or using a script written in your favorite language)
import your data as JSON and using the $date descriptor for converting date strings into Date instances
