ALTER COLUMN NOT NULL, not enough space in the log file I am trying to run the following DDL
ALTER TABLE [dbo].[table_name] ALTER COLUMN [Value] [float] NOT NULL

This generates a large amount of log file data, and there is not enough space for it on the server.
Is it possible to somehow reduce the information being logged?
I'm using Microsoft SQL Server 2016 (SP1-CU15) (KB4495257)
you might find it faster to create a new table, truncate the old, and then re-insert:
select t.*
into temp_my_table
from [dbo].[table_name] t;

truncate table [dbo].[table_name];  -- back it up first!

alter table [dbo].[table_name] alter column [Value] [float] NOT NULL

insert into [dbo].[table_name]
select t.*
from temp_my_table t;

You may have to pay attention if you have insert triggers or identity columns.
