I used SSMA to migrate 5 million records from Access to SS express 2012. The .mdf is 7.5 gigs, the log is 5.5 gigs. I thought maybe typing 'Checkpoint' in the query window would help, says 'Query executed successfully' but no change in size.
I tried this query
select log_reuse_wait, log_reuse_wait_desc from sys.databases where name like 'access2014'
and it shows the two values '0' and 'Nothing' as described here

but I don't know what that means. I also tried dbcc opentran which reports
No active open transactions.
so why is my log so big? I'm running out of disk space.
