hypertable

Is it possible to save results of a Hypertable shell query into a file?

I need some data out of my hypertable. I can inspect the data with the hypertable shell and was curios whether it is possible to pipe the result of a HQL query into a file. This would be useful for further investigations when the result set is large and one wants to format it or something else.

Any ideas?

Solution

  • sure:

    SELECT * FROM table INTO FILE "file.txt";

    You can even compress the file:

    SELECT * FROM table INTO FILE "file.txt.gz";

    Type help select in the shell and you will get more info.
