mongoimport

I have downloaded huge chunks of data in the format in csv. I am using mongoimport to enter the data into MongoDB for processing. How do I get the date into date format recognized by MongoDB? sample data with header Date, Open Price, High Price, Low Price, Last Traded Price , Close Price, Total Traded Quantity, Turnover (in Lakhs) 04-Apr-2014,901,912,889.5,896.75,892.85,207149,1867.08 03-Apr-2014,908,918,897.65,900,900.75,156260,1419.9 02-Apr-2014,916,921.85,898,900.7,900.75,175990,1591.97 Salvador Dali As far as I know, there is no way to do this with mongoimport . But this is achievable by

I have a lot of json files in archive and i need to import them into mongo per one operation (i think that it might be in cycle). Have you any ideas about this? Sumeet If you are in a Linux/Unix shell you can try for filename in *; do mongoimport -d mydb -c $filename; done If you are on Windows: FOR %i IN (C:\mongodbData\*.json) DO mongoimport --db dbName --collection colection --type json --file %i You need to use mongorestore for recovery from dump, created by the mongoexport http://docs.mongodb.org/v2.6/reference/program/mongorestore/ for example mongorestore --drop --oplogReplay mongodb/

I have a mongo document with a structure like: { "foo": { "bar1": "val1", "bar2": "val2"} } I'd like to import my data from a csv using mongoimport --type csv --headerline [...] I am not sure how to format the field name in the csv to address the nested structure. For instance: test.csv: foo.bar1 example returns { "_id" : ObjectId("4e9d9d25c5d8708e1f51cdbc"), "foo.bar1" : "example" } instead of the desired output: { "_id" : ObjectId("4e9d9d25c5d8708e1f51cdbc"), "foo: {"bar1" : "example"} } The field name seems to be interpreted as a string regardless of its value. Things like foo[bar1] and foo

I want to import dump data from my .gz file. Location of file is home/Alex/Documents/Abc/dump.gz and the name of db is "Alex" . I have tried mongorestore --gzip --db "Alex" /home/Alex/Documents/Abc/dump.gz But it shows error: 2018-10-31T12:54:58.359+0530 the --db and --collection args should only be used when restoring from a BSON file. Other uses are deprecated and will not exist in the future; use --nsInclude instead 2018-10-31T12:54:58.359+0530 Failed: file /home/Alex/Documents/Abc/dump.gz does not have .bson extension. How can I import it? Dump command: mongodump --host localhost:27017 -

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"
