Question

My application’s database mydb has different collation than tempdb. I get a lot of exceptions comparing string values between tempdb temporary tables and mydb persistent tables.
It was decided to create mydb with same collation as tempdb.
The collation must be set automatically using script. I’ve tried this:

DECLARE @SQLCollation sql_variant
SELECT @SQLCollation = DATABASEPROPERTYEX('tempdb', 'Collation')
ALTER DATABASE mydb COLLATE @SQLCollation -- doesn't work
ALTER DATABASE mydb COLLATE Latin1_General_CI_AS -- works, but doesn't suit me because I have to type in collation myself in this SQL

So how do I set the same collation for mydb as for tempdb?

Answer 1

DECLARE @SQLCollation NVARCHAR(1000)
SELECT @SQLCollation = 'ALTER DATABASE MyDb COLLATE '+CAST(DATABASEPROPERTYEX('Tempdb', 'Collation') as NVARCHAR(1000))
exec (@sqlcollation)
