IMPORTANT:
Execute in the database context of where you created the log and working tables.			
										
ALL parameters are optional. If not specified, the defaults for each parameter are used.	

@Exec_Print 		1 = execute the SQL code generated by this SP;
					0 = print commands only
					
@printCmds			1 = print commands to screen;
					0 = do not print commands

@outputResults		1 = output fragmentation information after run completes;
					0 = do not output fragmentation information
					
@debugMode 			1 = display debug comments;
					0 = do not display debug comments
					
@timeLimit 			Limits how much time can be spent performing index defrags; expressed in minutes.
					NOTE: The time limit is checked BEFORE an index defrag begins, thus a long index defrag can exceed the time limit.

@dbScope 			Specify specific database name to defrag; if not specified, all non-system databases plus msdb and model will be defragmented.

@tblName 			Specify if you only want to defrag indexes for a specific table, format = schema.table_name; if not specified, all tables will be defragmented.

@defragOrderColumn 	Defines how to prioritize the order of defrags. Only used if @Exec_Print = 1.
					range_scan_count = count of range and table scans on the index; this is what can benefit the most from defragmentation;
					fragmentation = amount of fragmentation in the index;
					page_count = number of pages in the index; bigger indexes can take longer to defrag and thus generate more contention; may want to start with these;

@defragSortOrder 	The sort order of the ORDER BY clause on the above query on how to prioritize the order of defrags.
					ASC (ascending)
					DESC (descending) is the default.

@forceRescan 		Action on index rescan. If = 0, a rescan will not occur until all indexes have been defragmented. This can span multiple executions.
					1 = force a rescan
					0 = use previous scan, if there are indexes left to defrag

@defragDelay 		Time to wait between defrag commands; gives the server a breathe between runs
					
@ixtypeOption		NULL = all indexes will be defragmented;
					1 = only Clustered indexes will be defragmented;
					0 = only Non-Clustered indexes will be defragmented (includes XML and Spatial Indexes);

@minFragmentation 	Defaults to 5%, will not defrag if fragmentation is less.
					Refer to http://msdn.microsoft.com/en-us/library/ms189858.aspx

@rebuildThreshold 	Defaults to 30%. greater than 30% will result in rebuild instead of reorganize.
					Refer to http://msdn.microsoft.com/en-us/library/ms189858.aspx
										
@rebuildThreshold_csDefaults to 10%. Greater than 10% will result in columnstore rebuild.
					Refer to https://msdn.microsoft.com/en-us/data/dn589807(v=sql.120)
										
@minPageCount 		Specifies how many pages must exist in an index in order to be considered for a defrag. Default to an extent. Refer to http://msdn.microsoft.com/en-us/library/ms189858.aspx
					NOTE: The @minPageCount will restrict the indexes that are stored in tbl_AdaptiveIndexDefrag_Working table and can render other options inoperative.

@maxPageCount 		Specifies the maximum number of pages that can exist in an index and still be considered for a defrag.
					Useful for scheduling small indexes during business hours and large indexes for non-business hours.
					NOTE: The @maxPageCount will restrict the indexes selective for defrag; 								

@fillfactor 		1 = original from when the index was created or last defragmented;
					0 = default fill factor

@scanMode 			Specifies which scan mode to use to determine fragmentation levels. Options are:
					LIMITED = the fastest mode and scans the smallest number of pages.
							For an index, only the parent-level pages of the B-tree (that is, the pages above the leaf level) are scanned.
							For a heap, only the associated PFS and IAM pages are examined; the data pages of the heap are not scanned.
							Recommended for most cases.
					SAMPLED = returns statistics based on a 1 percent sample of all the pages in the index or heap.
							If the index or heap has fewer than 10,000 pages, DETAILED mode is used instead of SAMPLED.
					DETAILED = scans all pages and returns all statistics. Can cause performance issues.

@onlineRebuild 		1 = online rebuild if possible; only in Enterprise Edition;
					0 = offline rebuild

@sortInTempDB 		When 1, the sort results are stored in TempDB. When 0, the sort results are stored in the filegroup or partition scheme in which the resulting index is stored.
					If a sort operation is not required, or if the sort can be performed in memory, SORT_IN_TEMPDB is ignored.
					Enabling this option can result in faster defrags and prevent database file size inflation.	Just have monitor TempDB closely.
					More information here: http://msdn.microsoft.com/en-us/library/ms188281.aspx and http://msdn.microsoft.com/en-us/library/ms179542.aspx and http://msdn.microsoft.com/en-us/library/ms191183.aspx
					1 = perform sort operation in TempDB
					0 = perform sort operation in the indexes database

@maxDopRestriction 	Option to specify a processor limit for index rebuilds
					
@updateStats		1 = updates stats when reorganizing;
					0 = does not update stats when reorganizing	
					
@updateStatsWhere	Update statistics within certain thresholds (http://support.microsoft.com/kb/195565/en-us)
					1 = updates only index related stats;
					0 = updates all stats in entire table
										
@statsSample		NULL = perform a sample scan on the target table or indexed view. The database engine automatically computes the required sample size;
					FULLSCAN = all rows in table or view should be read to gather the statistics;
					RESAMPLE = statistics will be gathered using an inherited sampling ratio for all existing statistics including indexes

@ix_statsnorecompute	1 = STATISTICS_NORECOMPUTE on will disable the auto update statistics.
					If you are dealing with stats update with a custom job (or even with this code by updating statistics), you may use this option;
					0 = default which is with STATISTICS_NORECOMPUTE off
					
@statsIncremental	When Incremental is ON, the statistics created are per partition statistics. 
					When OFF, the statistics tree is dropped and SQL Server re-computes the statistics. This setting overrides the database level INCREMENTAL property. (http://msdn.microsoft.com/en-us/library/ms190397.aspx)
					NULL = Keep server setting;
					1 = Enable auto create statistics with Incremental
					0 = Disable auto create statistics with Incremental

@dealMaxPartition 	If an index is partitioned, this option specifies whether to exclude the right-most populated partition, or act only on that same partition, excluding all others.
					Typically, this is the partition that is currently being written to in a sliding-window scenario.
					Enabling this feature may reduce contention. This may not be applicable in other types of partitioning scenarios.
					Non-partitioned indexes are unaffected by this option. Only in Enterprise Edition.
					1 = exclude right-most populated partition										
					0 = only right-most populated partition (remember to verify @minPageCount, if partition is smaller than @minPageCount, it won't be considered)										
					NULL = do not exclude any partitions
					
@dealLOB			Specifies that all pages that contain large object (LOB) data are compacted. The LOB data types are image, text, ntext, varchar(max), nvarchar(max), varbinary(max), and xml.
					Compacting this data can improve disk space use.
					Reorganizing a specified clustered index compacts all LOB columns that are contained in the clustered index.
					Reorganizing a non-clustered index compacts all LOB columns that are nonkey (included) columns in the index.
					0 = compact LOBs when reorganizing (default behavior);
					1 = does not compact LOBs when reorganizing	

@ignoreDropObj		If a table or index is dropped after the defrag cycle has begun, you can choose to ignore those errors in the overall outcome,
					thus not showing a job as failed if the only errors present refer to dropped database objects.	
					0 = includes errors about objects that have been dropped since the defrag cycle began (default behavior);
					1 = for error reporting purposes, ignores the fact that objects have been dropped since the defrag cycle began				

@disableNCIX		If disk space is limited, it may be helpful to disable the non-clustered index before rebuilding it;
					When a non-clustered index is not disabled, the rebuild operation requires enough temporary disk space to store both the old and new index;
					However, by disabling and rebuilding a non-clustered index in separate transactions, the disk space made available by disabling the index can be reused by the subsequent rebuild or any other operation;
					No additional space is required except for temporary disk space for sorting; this is typically 20 percent of the index size;
					Does not disable indexes on partitioned tables when defragging a subset of existing partitions;
					Keeps track of whatever indexes were disabled by the defrag cycle. In case the defrag is cancelled, it will account for these disabled indexes in the next run.
					0 = does NOT disable non-clustered indexes prior to a rebuild (default behavior);
					1 = disables non-clustered indexes prior to a rebuild (space saving feature)

@offlinelocktimeout	As set in SET LOCK_TIMEOUT (http://msdn.microsoft.com/en-us/library/ms189470.aspx)
					-1 = (default) indicates no time-out period
					Any other positive integer = sets the number of milliseconds that will pass before Microsoft SQL Server returns a locking error

@onlinelocktimeout	Indicates a time-out period for locks to wait at low priority, expressed in minutes; this is valid from SQL Server 2014 onwards

@abortAfterwait 	If the online low priority lock timeout occurs, this will set the action to perform afterwards.
					NULL = (default) After lock timeout occurs, continue waiting for the lock with normal (regular) priority;
					1 = Exit the online index rebuild DDL operation currently being executed without taking any action;
					2 = Kill all user transactions that block the online index rebuild DDL operation so that the operation can continue.

@dealROWG			Set Columnstore reorg option to compress all rowgroups, and not just closed ones		
					0 = (default) compress closed rowgroups on columnstore.
					1 = compress all rowgroups on columnstore, and not just closed ones.
					
@getBlobfrag		Indicates whether to exclude or include blobs from fragmentation scan.
					0 = (default) exclude blobs from fragmentation scan.
					1 = include blobs and off-row data when scanning for fragmentation.

For @exceptionMask_tables (optional) enter table names separated by commas ('table_name_1, table_name_2, table_name_3').
For @exceptionMask_indexes (optional) enter index names separated by commas ('index_name_1, index_name_2, index_name_3').
