Modify the Data Type of MongoDB.

Modify the Data Type of MongoDB.

If a type write error occurs, modify it in the command line as follows.

Db. jobtracker_data.find ({'Collect _ time': {$ type: 2 }}). forEach (function (x) {x. collect_time = parseInt (x. collect_time); db. jobtracker_data.save (x );})

The value of collect_time should be long, and the result is accidentally changed to string. The preceding command line uses $ type 2 to search for documents whose collect_time value type is string, and passes a JavaScript function to forEach.

X is the current record (doc), which is easy to convert and save.
