Sneakpreview on Version 7 - Datavault - Hashtype

Exasol Alumni

As we are nearing the GA of Exasol V7, we want to give the more technical users a view into how you can work with some of the new features.

@exa-Uwe our Trainer has compiled some videos to showcase a few of the changes. A mayor topic of Version 7 is an improved support for Datavault.

See this video for the use of Hashtypes in Exasol: https://youtu.be/la5wDu5B2dM

Quick question...

If I'm using real GUIDs or pieces of them (0-F), do I need to recreate the columns?  Can I just update the data type with a MODIFY statement?

You can use a MODIFY statement for that 😊.
Short example:

create or replace table a(x char(36) ascii);
insert into a values 'a7b38db6-d985-42ca-a3ba-cc78c3d5bc2f';
alter table a modify column x hashtype(16 byte);
