Mongoimport csv files with string _id and upsert

Question

I\'m trying to use mongoimport to upsert data with string values in _id. Since the ids look like integers (even though they\'re in quotes), mongoimport treats them as intege

Answer 1

I was able to prefix the numeric string and that worked for me. Example:

00012345 was imported as 12345 (Type Int) string00012345 was imported as string00012345 (Type String)

My source was a SQL database so I just did

select 'string'+column as name

Of course, you also need to do a bit of post-processing to parse the string, but far less effort than converting a rather large tsv file to json.

I also added +1 to the jira link above for the enhancement.
