Couchbase N1QL queries on server

问题:

I used the online N1QL tutorial to practices writing queries. Now that I have a couchbase server of my own, I want to query my own data.

My questions is

Where in the Couchbase server can I write my queries?

thanks

Remember that N1Q1 is still in Beta.

The way it works is that you have to run Couchbase Query Server (aka CBQ). It runs in a default port 8093 (see N1QL) The query server will connect to the specified Couchbase instance/cluster. e.g.

cbq-engine -couchbase <CB-location> 

Once CB Query Engine up and running you can run command line client and in a command prompt can issue your N1QL statements, e.g.:

cbq -engine http://your-cb-host:8093/  cbq> SELECT 'Hello World' AS Greeting {     "resultset": [         {             "Greeting": "Hello World"         }     ],     "info": [         {             "caller": "http_response:160",             "code": 100,             "key": "total_rows",             "message": "1"         },         {             "caller": "http_response:162",             "code": 101,             "key": "total_elapsed_time",             "message": "4.0002ms"         }     ] }

N1QL is released and available as part of Couchbase Server. Please download Couchbase Server 4.1 http://www.couchbase.com/nosql-databases/downloads

Just to note, there is a new developer preview of N1QL out now (http://docs.couchbase.com/developer/n1ql-dp3/n1ql-intro.html) and the way to connect to a Couchbase cluster has changed from the answer given by user1697575; it's now:

cbq-engine -datastore <CB-location> 

The Couchbase query engine can also serve N1QL queries from a file system, and there is a file system included in the download that can be queried:

cbq-engine -datastore=dir:./data
