(Back to #mongodb overview) (Back to channel listing) (Animate logs)
[00:07:29] <CHC> does anyone know a way that i can take two collections and merge them? i have a collection of snapshots that have been processed, i want to insert rows where the objectid (_id) does not exist, but not touch the existing record at all if one exists already? maybe with mongorestore?
[06:47:05] <hendry> hi, how do I push, but only if the value is not there already https://docs.mongodb.com/manual/reference/operator/update/push/
[19:34:26] <netgene> How do I aggregate all "string" from multiple records? { text: "foo" }, { text: "bar"} to get, results: "foo bar" ?
[19:59:45] <netgene> everyone is busy doing mongo stuff.. ? :(
