    How to correctly Shrink Log File for SQL Server

    In case your transaction log reaches abnormal dimension (e.g. you forgot the backup of the log in your maintenace plan...) it is highly useful this script that allows you to safely shrink the transaction log to the wanted dimension
    USE AdventureWorks
    GO
    
    -- Use some dynamic SQL just only not to re-write several times the name 
    -- of your db, or to insert this snippet into a loop for all your databases...
    DECLARE @dbname varchar(50) = 'AdventureWorks';
    DECLARE @logFileName varchar(50) = @dbname  + '_log';
    DECLARE @SQL nvarchar(max);
