N1QL and Node on Couchbase

问题

I am trying to use N1QL with Node.js SDK of Couchbase. Here is my code:

 var config = require('../../config/init');
        var N1qlQuery = require('couchbase').N1qlQuery;
        var query = N1qlQuery.fromString("SELECT * FROM users");
        var db = couchbaseService();
        console.log('start');
        db.query(query, function(err, result) {
            if (err) {
                console.log('inside err');
                console.log(err);
                return;
            }
            console.log('No error in NIQL');
            console.log(result.object);
        });

Here is the error:

 TypeError: Cannot read property 'length' of undefined

Please note,problem is not about connecting to bucker or server. I used .get() and .insert() and they are working fine.something missing in N1QL library. Anybody can Help?

回答1:

You have to enable the n1ql on the given bucket:

bucket.enableN1ql(serverUrl+":8093")

More can be found here: http://docs.couchbase.com/sdk-api/couchbase-node-client-2.0.0/Bucket.html#enableN1ql
