I am now using MongoTalk for a project and I wanted to use distinct. But there seems to be no support in the version that I do have. So, I had a look under the hood on how the driver worked. I came up with this: mongo := Mongo default open. db := mongo databaseNamed: 'somedb'. aCommandDict := { 'distinct' -> 'somecollection'. 'key' -> 'XYZ'. 'query' -> nil } asDictionary. reply := db command: aCommandDict. (CollectionValidation on: reply) isOK. distinct := reply at: #values. It would be nice to have some support for the distinct command in MongoTalk. Especially in order to populate dropboxes etc with choices. I have been looking at Voyage too but the data is not produced by my application, so there is little use for me to have #instanceOf fields etc. I will also need aggregation commands on my data set. Are these things somewhere to be found or do I have to look into how the shell does things and move from there? TIA Phil
