Just a quick script to check your database compatibility level... and change it, if you need to. This statement will bring back the compatibility levels for each database in the system:
/* query the db
compatibility level */
SELECT
name [database],
compatibility_level ,
[version] =
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'
END
FROM
sys.databases;
And when you need to change it:
/* change db
compatibility level */
ALTER DATABASE YourDatbaseName
SET COMPATIBILITY_LEVEL =
110;
Be wary, though, about changing the compatibility level. Often times by doing so, you will be unable to take advantage of certain features. Take a look at this MSDN reference for more details on the differences between higher/lower compatibility levels:
