How to rename a bucket in couchbase?

I have a bucket name 0001 when I use the following N1QL statement I get a "5000" syntax error:

cbq> Select * from 0001;
{
    "requestID": "f2b70856-f80c-4c89-ab37-740e82d119b5",
    "errors": [
        {
            "code": 5000,
            "msg": "syntax error"
        }
    ],
    "status": "fatal",
    "metrics": {
        "elapsedTime": "349.733us",
        "executionTime": "204.442us",
        "resultCount": 0,
        "resultSize": 0,
        "errorCount": 1
    }
}

I think it takes 0001 as a number and not as a bucket name, is there an easy way to rename it?

There is no way I am seeing to rename. I checked the CLI as well and nothing. Your best bet, if you can, is to create a new bucket with the settings you want and then use cbtransfer to move the data over from the old to the new bucket. This is an online operation.

In this case you can use back ticks in N1QL to escape the bucket name:

cbq> Select * from `0001`;
{
    "requestID": "f48527e6-6035-47e7-a34f-90efe9f90d4f",
    "signature": {
        "*": "*"
    },
    "results": [
        {
            "0001": {
                "Hello": "World"
            }
        }
    ],
    "status": "success",
    "metrics": {
        "elapsedTime": "2.410929ms",
        "executionTime": "2.363788ms",
        "resultCount": 1,
        "resultSize": 80
    }
}

Currently there is noway to rename a bucket instead you could do one of the following:

  1. Backup the bucket using cbbackup. Then recreate it and restore it using cbrestore.
  2. Create a second cluster and use XDCR to transfer the data to the new cluster with the correctly named bucket.
