Rebuild MS SQL log file

ALTER DATABASE <db> REBUILD LOG ON (NAME=<db>_log, FILENAME='E:\*log.ldf') ;

Unable to open physical file - Operating system error 5: 5

Simply open "SQL Server Configuration Manager"
In side "SQL Server Configuration Manager" in the right-side, right-click on the service name which you are using currently
Select Properties
Now you can do one of the followings:
     - Change the log on service account to an account with appropriate privileges.
     OR
     - Give the selected log on service account an appropriate privileges on your file system (for example: D:\SQLDatabase\)

My quick fix was to:
- right-click on the file in Windows Explorer, select Properties
- select the Security tab
- Click Advanced
- Click Change Permission
- Uncheck "Include inheritable permissions...", a window will open
- Click Remove (removes all permissions), the window will close
- Click Add
- Enter your login name and click OK, the permission window will open
- Check Full Control - Allow
- Click OK, OK, OK, OK

Do this for the MDF and LDF files.

I was then able to attach the database.

Cheers,

Solution To The MSSQL Server “Suspect”

EXEC sp_resetstatus ‘DATABASE_NAME’;
ALTER DATABASE DATABASE_NAME SET EMERGENCY
DBCC checkdb(‘DATABASE_NAME’)
ALTER DATABASE DATABASE_NAME SET SINGLE_USER WITH ROLLBACK IMMEDIATE
DBCC CheckDB (‘DATABASE_NAME’, REPAIR_ALLOW_DATA_LOSS)
ALTER DATABASE DATABASE_NAME SET MULTI_USER

Convert SQL server datetime

http://www.sqlusa.com/bestpractices/datetimeconversion/

Execute the following T-SQL scripts in Microsoft SQL Server Management Studio (SSMS) Query Editor to demonstrate T-SQL CONVERT and CASTfunctions in transforming string SQL date formats, string time & string datetime data to datetime data type. Practical examples for T-SQL DATE/ DATETIME functions.

-- SQL Server string to date / datetime conversion - datetime string format sql server

-- MSSQL string to datetime conversion - convert char to date - convert varchar to date

-- Subtract 100 from style number (format) for yy instead yyyy (or ccyy with century)

SELECT convert(datetime, 'Oct 23 2012 11:01AM', 100) -- mon dd yyyy hh:mmAM (or PM)

SELECT convert(datetime, 'Oct 23 2012 11:01AM') -- 2012-10-23 11:01:00.000

-- Without century (yy) string date conversion - convert string to datetime function

SELECT convert(datetime, 'Oct 23 12 11:01AM', 0) -- mon dd yy hh:mmAM (or PM)

SELECT convert(datetime, 'Oct 23 12 11:01AM') -- 2012-10-23 11:01:00.000

-- Convert string to datetime sql - convert string to date sql - sql dates format

-- T-SQL convert string to datetime - SQL Server convert string to date

SELECT convert(datetime, '10/23/2016', 101) -- mm/dd/yyyy

SELECT convert(datetime, '2016.10.23', 102) -- yyyy.mm.dd ANSI date with century

SELECT convert(datetime, '23-10-2016', 105) -- dd-mm-yyyy

-- mon types are nondeterministic conversions, dependent on language setting
