There isn't a command available to rename or change the data type of a column in Phoenix -- to do something like this, you need to drop a column and then create a new column.
If you have existing data that you want to migrate, I would suggest doing the following: 1. Create the new column (with the new name and possibly new type) 2. Run an UPSERT SELECT statement to copy/migrate data from the old column to the new column 3. Drop the old column - Gabriel On Fri, Sep 11, 2015 at 6:48 AM, Hafiz Mujadid <[email protected]> wrote: > Hi All! > > I want to rename a column in phoenix with hbase.
