Unidac 7.4.12 MongoDB 4.2

Post by sasa.pikija » Sun 18 Aug 2019 22:42

Hi.
Is MongoDB v4.2 supported by Unidac 7.4.12?

I'm using win32 dll from Unidac directory and I managed to connect to MongoDB, but in "Info" tab (in UniConnection) says:
Server version: 3.20.0 (direct access)
Client version: 3.20.0

When I try to execute simple find (like described in Unidac help) I'm getting error: unrecognized token: "{"

UniQuery1.SQL.Text := '{"find":"restaurants", "filter":{"cuisine":"italian"}, "sort":{"name:1}}';
UniQuery1.Open;

There is error in this line in Unidac help: "sort":{"name:1} should be "sort":{"name":1} - missing second ", but, in both cases, error is the same.

Am I doing something wrong or MongoDB v4.2 is not supported by Unidac v7.4.12?

Thanks.
