	This script displays your most resource-intensive queries from the plan cache,
	and points to ways you can tune these queries to make them faster.


	To learn more, visit http://FirstResponderKit.org where you can download new
	versions for free, watch training videos on how it works, get more info on
	the findings, contribute your own code, and more.

	Known limitations of this version:
	 - SQL Server 2008 and 2008R2 have a bug in trigger stats, so that output is
	   excluded by default.
	 - @IgnoreQueryHashes and @OnlyQueryHashes require a CSV list of hashes
	   with no spaces between the hash values.

	Unknown limitations of this version:
	 - May or may not be vulnerable to the wick effect.

	Changes - for the full list of improvements and fixes in this version, see:

This script gives you a prioritized list of why your SQL Server is slow right now.

This is not an overall health check - for that, check out sp_Blitz.

To learn more, visit http://FirstResponderKit.org where you can download new
versions for free, watch training videos on how it works, get more info on
the findings, contribute your own code, and more.

Known limitations of this version:
 - Only Microsoft-supported versions of SQL Server. Sorry, 2005 and 2000. It
   may work just fine on 2005, and if it does, hug your parents. Just don''t
   file support issues if it breaks.
 - If a temp table called #CustomPerfmonCounters exists for any other session,
   but not our session, this stored proc will fail with an error saying the
   temp table #CustomPerfmonCounters does not exist.
 - @OutputServerName is not functional yet.
 - If @OutputDatabaseName, SchemaName, TableName, etc are quoted with brackets,
   the write to table may silently fail. Look, I never said I was good at this.

Unknown limitations of this version:
 - None. Like Zombo.com, the only limit is yourself.

Changes - for the full list of improvements and fixes in this version, see:

This script analyzes the design and performance of your indexes.

To learn more, visit http://FirstResponderKit.org where you can download new
versions for free, watch training videos on how it works, get more info on
the findings, contribute your own code, and more.

Known limitations of this version:
 - Only Microsoft-supported versions of SQL Server. Sorry, 2005 and 2000.
 - Index create statements are just to give you a rough idea of the syntax. It includes filters and fillfactor.
 --        Example 1: index creates use ONLINE=? instead of ONLINE=ON / ONLINE=OFF. This is because it is important 
           for the user to understand if it is going to be offline and not just run a script.
 --        Example 2: they do not include all the options the index may have been created with (padding, compression
           filegroup/partition scheme etc.)
 --        (The compression and filegroup index create syntax is not trivial because it is set at the partition 
           level and is not trivial to code.)
 - Does not advise you about data modeling for clustered indexes and primary keys (primarily looks for signs of problems.)

Unknown limitations of this version:
 - We knew them once, but we forgot.

           5) A resumable rowstore CREATE INDEX [...] DROP_EXISTING = ON that is currently running
           6) A resumable rowstore CREATE INDEX [...] DROP_EXISTING = ON that is currently paused
        In cases 1 and 2, sys.indexes has no data at all about the index in question.
        This makes #IndexSanity much harder to use, since it depends on sys.indexes.
        We must therefore get as much from #IndexResumableOperations as possible.

    Variables you can use:

        /*Filtering parameters*/
        @DatabaseName: If you want to filter to a specific database

        @StartDate: The date you want to start searching on, defaults to last 7 days

        @EndDate: The date you want to stop searching on, defaults to current date

        @ObjectName: If you want to filter to a specific able.
                     The object name has to be fully qualified ''Database.Schema.Table''

        @StoredProcName: If you want to search for a single stored proc
                     The proc name has to be fully qualified ''Database.Schema.Sproc''

        @AppName: If you want to filter to a specific application

        @HostName: If you want to filter to a specific host

        @LoginName: If you want to filter to a specific login

        @DeadlockType: Search for regular or parallel deadlocks specifically

        /*Extended Event session details*/
        @EventSessionName: If you want to point this at an XE session rather than the system health session.

        @TargetSessionType: Can be ''ring_buffer'',  ''event_file'', or ''table''. Leave NULL to auto-detect.

        /*Output to a table*/
        @OutputDatabaseName: If you want to output information to a specific database

        @OutputSchemaName: Specify a schema name to output information to a specific Schema

        @OutputTableName: Specify table name to to output information to a specific table

        /*Point at a table containing deadlock XML*/
        @TargetDatabaseName: The database that contains the table with deadlock report XML

        @TargetSchemaName: The schema of the table containing deadlock report XML

        @TargetTableName: The name of the table containing deadlock report XML
       
        @TargetColumnName: The name of the XML column that contains the deadlock report
       
        @TargetTimestampColumnName: The name of the datetime column for filtering by date range (optional)

   
    To learn more, visit http://FirstResponderKit.org where you can download new
    versions for free, watch training videos on how it works, get more info on
    the findings, contribute your own code, and more.

    Known limitations of this version:
     - Only SQL Server 2012 and newer is supported
     - If your tables have weird characters in them (https://en.wikipedia.org/wiki/List_of_xml_and_HTML_character_entity_references) you may get errors trying to parse the xml.
       I took a long look at this one, and:
        1) Trying to account for all the weird places these could crop up is a losing effort.
        2) Replace is slow af on lots of xml.

    Unknown limitations of this version:
     - None.  (If we knew them, they would be known. Duh.)
