-- Installation procedure
--
-- Step 1 : Simply launch this script, it install YourSQLDba database and objects requiered for maintenance
-- Step 2 : ON FIRST INSTALL ONLY, run YourSQLDba_SetupOf_SqlAgent_MaintenanceJobs_DatabaseMail. 
--          This script setup SQLAgent Tasks, Database Mail
--          using supplied parameters. 
--          Example for it is supplied at the end of this script.
--          First two parameters are backups directories for log and for complete database backups
--          Thrid parameter is email of the database admin or other operator 
--          Forth parameter is the address or name of a mail server that will
--          accept anonymous smtp from your sql server (from database mail).  
--
-- Upgrades : Just rerun the new version of the script as described in Step 1 only
--
-- Customizations are possible int the SQL Agent Job generated by the setup.
-- Maintenance parameters are customizable at the job step level.
-- Once defined, more steps can be added to the job with different parameters for different databases sets
-- More steps can be added for operating systems commands especially to move backups files

-- You can send your comments and/or source code to pelsql@hotmail.com
-- 
-- Any upgrades must take into account that the script must finds itself the state of the current 
-- installed version and bring it to the latest version (the actual script).
--
-- Samples of this process are kept from previous version as if it ever existed
-- but because of translation to identifiers in english, this version never really existed.
--
-- However the method proove to be 100% successful with the previous french version.
-- Many users of the original version upgraded their solution without problem and from any previous version
--
-- It helped very much in making the project easy to upgrade, as it is always the same :
-- re-run the latest script to upgrade to the last version.
--
-- *****************************************************************************************************
-- For users of previous version set new solution to 'YourSQLDba' database

This view is an handy way to define constants that define specific parameters
or more generally more useful constant. By cross joining this view, all constants
becomes accessible to queries using them, at no cost.
***BONUS***: When using S#.Enums intellisence helps to find constants
for a given module easily when they are in the form Modulename@option, 
just by starting typing module name
===Purpose===*/

/*===Purpose===
This function is to get some SQL Code wrapped in a multiline 
comment that must starts and ends by a Delim of your choice
/*"Delim"
and end by 
"Delim"*/ 
It simplifies coding of code definition or code template
instead of using litteral strings by having not to care about quotes.

The comment may be extracted depending @Moduleref Sql_Variant parameter from:
■ The running batch or directly in a stored procedure.
■ @@ProcId (id of the running SP)
■ Any SQL module name including itself (like a stored proc, function, Trigger Or View)
■ The topmost calling SQL (ex: a comment in the batch starting before the called stored proc)

This function have a very extensive use in this library!

-- Main maintenance sp have numerous parameters and many of them are used also
-- in stored procedures and functions in the underlying call stack.  
--
-- Some underlying procedures may also be call directly by the user, and when it is the case,
-- this is also a problem.
--
-- These values are kind of global. This is a context of the maintenance process.
-- Passing them (they are numerous) across the call stack is a coding pain and bloat the code. 
--
-- To workaround this, this function make them available, indirectly, through 
-- Maint.JobHistory in which the are pre-stored. See function dbo.ScriptSetGlobalAccessToPrm to see how it is done. 
--
-- dbo.ScriptSetGlobalAccessToPrm generates a script that insert theses values, and also from the jobNo value obtained 
-- on insert (identity column), it set a session context containing this value.  If packs parameters into a jSonPrms col
-- and stored also the topmost calling SQL into mainSqlCmd
--
-- This function gets the JobNo from the session_context which is the key to Maint.JobHisotry, and then gets parameters 
-- packed in a jSon format (JsonPrms). It shreds them into differents colums into a single row, each column reflecting the
-- column name. It also get from Maint.JobHistory the main SQL query.  This last value is very valuable for reporting, auditing and debugging

Create OR Alter Function maint.HistoryView (@StartDateTime Nvarchar(23), @EndDatetime Nvarchar(23), @FilterOption Int)
-- ----------------------------------------------------------------------------------------------------------
-- Function to list filter history in a more readeable form, based on a datetime range.
--
-- This function performs three type of reporting.
-- 1) List all jobs in a time range, with all events that occured in that time range
-- 2) List only job entries that belongs a the jobNo of an execution context (available only when called from a job)
-- 3) List only job entries that have an error in the time range
--
-- The function is intended to be used by YourSqlDba reporting, but can be used by any user with the proper rights.
-- YourSqlDba reporting use parameter HV$ShowOnlyErrorOfJobFromSessionContext to get only the errors of the current job
-- so yMaint.InstructionsToGetJobHistory uses it to find if an error occured in the job and produces a report
-- that is different depening the occurence of an error or not.
--
-- When listing jobs in a time range, we may encounter multiple concurrent jobs in the same time range (ex: main mantenance and log backups)
-- and we want to show errors for them to.
-- However it is visually hard to notice the jobNo change, so columns are added to display the calling task, query, and job name
-- and they are displayed only when the jobNo changes.
--
-- Since version 7.0, error message for improper dates are added.
-- Language setting may affect datetime parameter interpretation, so we use string parameters.
-- The official date format supported is 'YYYY-MM-DD hh:mm:dd.mmm' (format 121 of the convert function)
-- It can be less precise, but parts must match for those that are present.
-- For example: French language setting (either explicitely, or at the login or in conenction parameters)
-- make month and day switch places. Not only it may give another date, but even an invalid one.
-- So parameters are now of nvarchar type and an explicit TRY_CONVERT to datetime conversion from date format 121 is attempted.
-- So the the date will be properly interpreted as year, month, day
-- Special handling of invalid date give a singles row output in which the "Line" hold a meaningful error message
