I really liked that script, but, being an efficiency fanatic, I thought I would improve it just a little. Instead of building the SQL statement and then using replace to alter it, my version just builds the correct sql statement the first time. Here it is:
USE MASTER
declare
@isql varchar(2000),
@dbname varchar(64),
@logfile varchar(128)
declare c1 cursor for
SELECT d.name, mf.name as logfile--, physical_name AS current_file_location, size
FROM sys.master_files mf
inner join sys.databases d
on mf.database_id = d.database_id
where recovery_model_desc <> 'SIMPLE'
and d.name not in ('master','model','msdb','tempdb')
and mf.type_desc = 'LOG'
open c1
fetch next from c1 into @dbname, @logfile
While @@fetch_status <> -1
begin
select @isql = 'ALTER DATABASE ' + @dbname + ' SET RECOVERY SIMPLE'
print @isql
--exec(@isql)
select @isql='USE ' + @dbname + ' checkpoint'
print @isql
--exec(@isql)
select @isql='USE ' + @dbname + ' DBCC SHRINKFILE (' + @logfile + ', 1)'
print @isql
--exec(@isql)
fetch next from c1 into @dbname, @logfile
end
close c1
deallocate c1
I'd have to test it but I don't believe that all those concatenations will necessarily be more efficient.
