tsql - How to check SQL Server Database compatibility after sp_dbcmptlevel is deprecated?

Question

According to BOL (SQL Server Books Online) on sp_dbcmptlevel,

This feature will be removed in a future version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible. Use ALTER DATABASE Compatibility Level instead.

Now, the only TSQL way I know of checking database compatibility is through sp_dbcmptlevel. As far as I know, ALTER DATABASE Compatibility Level is just for setting the compatibility level, not getting info.

How should one to get compatibility level without using GUI?

select name, compatibility_level , version_name = 
CASE compatibility_level
    WHEN 65  THEN 'SQL Server 6.5'
    WHEN 70  THEN 'SQL Server 7.0'
    WHEN 80  THEN 'SQL Server 2000'
    WHEN 90  THEN 'SQL Server 2005'
    WHEN 100 THEN 'SQL Server 2008/R2'
    WHEN 110 THEN 'SQL Server 2012'
    WHEN 120 THEN 'SQL Server 2014'
    WHEN 130 THEN 'SQL Server 2016'
    WHEN 140 THEN 'SQL Server 2017'
    WHEN 150 THEN 'SQL Server 2019'
    ELSE 'new unknown - '+CONVERT(varchar(10),compatibility_level)
END
