Hey Bryan, here is my version I was working on when I stumbled upon your version (wasn’t sure how to get the log names). It’s made for sql server 2005. Also I don’t like cursors so they’re not here.
——————————————
declare @SQLString NVARCHAR(MAX), @dbName as nvarchar(255), @logName as nvarchar(255)
declare @dbList as table( dbName nvarchar(255),logName nvarchar(255), runStatus bit default 0)

–Populate table variable with all db names and all db log file names
insert into @dbList (dbName,logName)
SELECT a.name, b.name from sys.databases a join sys.master_files b on a.database_id = b.database_id
where b.type = 1 AND a.name not in (‘master’, ‘model’, ‘msdb’, ‘tempdb’,'distribution’)
order by a.name
–Loop over all db
while (exists(select * from @dbList where runStatus=0))
begin
–Get first available database
SELECT top 1 @dbName = dbName, @logName = logName from @dbList where runStatus = 0
–Prepare sql statement here
SET @SQLString =
N’ USE ‘ + quotename(@dbName) + N’ ; ‘ +
N’ DBCC SHRINKFILE(‘ + quotename(@logName) + ‘ , 1) ; ‘ +
N’ BACKUP LOG ‘ + quotename(@dbName) +’ WITH TRUNCATE_ONLY ;’ +
N’ DBCC SHRINKFILE(‘ + quotename(@logName) + ‘ , 1) ;’
–Execute
EXECUTE sp_executesql @SQLString
–Flag used database
update @dbList set runStatus = 1 where dbName = @dbName
end

Have you tried using the built in function quotename() for T-SQL?
It returns the input string a valid SQL Server delimited identifier. ie, with [ ]

Very useful script.
