QUESTION
We have a working prototype in Google Cloud DataLab where we have made extensive use of the %%bq
'magics' to build up a parameterized query using various UDFs.
So something like:
...ANSWER
Answered 2017-Sep-18 at 16:35Have you tried finalQry.sql
? This will give you the query's SQL string. However, this will be before any parameter substitution, since this happens at execution time (your sample
call in this case).
See http://googledatalab.github.io/pydatalab/datalab.bigquery.html#datalab.bigquery.Query.sql
If you think getting the SQL string after substitution is a useful feature, you can open a feature request on the Github repo.
QUESTION
I've got a problem with pydatalab: I just installed it and normal querying and charting via cell magic works fine.
The wiki for pydatalab says, it's possible to add chart controls. But that wiki uses some old %%sql
syntax instead of the new %%bq query
one which don't work anymore.
Weird thing is, the following works fine:

I installed datalab like described.
If i try to make a chart with this %chart line -d data -f field1,field2
logic, something happens, but no plot appears.

QUESTION
I am trying to read a csv from google cloud storage in Google Cloud Datalab but its falling over with the following error message:
...ANSWER
Answered 2017-May-08 at 16:25The Datalab csv parser uses the python csv module under the hood, and that module itself doesn't support encodings/codecs.
If the file isn't too big you can use the gcs view command to load it into a variable, then encode it and pass it to a csv reader.
That command just reads the whole file, so if you need to limit the number of lines you'd have to use the read_lines() method in the Storage API.

Install pydatalab
If you'd like to work on the package, it's useful to be able to install from source. You will need the Typescript compiler installed.
