| | | How do you come up with creative ideas? Most of us are in the business of coming up with or developing solutions to problems. Some of these problems are things we have run into before. In those situations, the solution is perhaps well known or has solved the problem before. Still, many problems we face are new or are different enough that we cannot just use a solution we have used previously because it just doesn’t quite work. In these cases, it takes a creative mind to come up with new ideas that will become the solution to the problem. So how do you go about coming up with creative ideas? There are a couple of ways I have seen it done in the past. A great place to start is, getting together with co-workers and doing a brain storming session. There are a couple of benefits here. One, you are working with other people’s creativity, not just your own. Two, you can bounce your crazy ideas off some other people and see if any of them stick. It seems that often, when working together as a group, you can come up with some creative ideas that end up being good solutions. Another way you can come up with creative ideas is to give yourself freedom to think outside the box. It is difficult to describe, but so often we stifle our own ideas and creative thinking. We dismiss them as too farfetched. Or we only have a narrow perspective on how a problem can be solved. When we try to let go of the limitations we put on our thinking, we are freed up to have some creative thoughts. Now, don’t get me wrong, a lot of these thoughts or ideas will be pure rubbish. That is okay, because even ideas that will never work in a million years, might lead to another thought or idea that will work. When you don’t allow yourself the freedom to dream up a creative idea, you miss the opportunity to walk down a new path that may lead you to your final solution. Finally, it takes time. Nothing seems to hinder the creative process more than time constraints. Most of us have deadlines, projects that need to be done yesterday. The issue is, if you are only allowing yourself five minutes or a few hours to decide on a solution, you probably won’t be coming up with something all that creative. Give it a day, or two. You might be surprised as your subconscious mind continues to think about it and all of a sudden you come up with a great idea. In my experience, if you brainstorm with others, give yourself the freedom to think some new unshackled thoughts and give yourself enough time to mull it over, you can come up with some creative solutions. You never know with enough time, what path your creative thinking will lead you down. Hopefully, to a new solution to your problem. Let us know how you go about coming up with creative solutions to your problems? Ben Kubicek from SQLServerCentral.comJoin the debate, and respond to today's editorial on the forums |

| | | | | Hugo Kornelis from SQLServerCentral.com To fully appreciate just how different columnstore indexes are, and why work so well in reporting and online analytical processing (OLAP) workloads, but not for online transaction processing (OLTP), we must first look at the traditional “rowstore” indexes.

| Yesterday's Question of the Day |
| Yesterday's Question (by Jagadish Kumar Punnapu): On a table having 10 million rows, 4 non-clustered indexes and 1 clustered index have to be created. In this scenario, which order of creation is recommended?
Answer: Create the clustered index first and then create the 4 non-clustered indexes Explanation: If a clustered index is created on a heap with several existing non-clustered indexes, all the non-clustered indexes must be rebuilt so that they contain the clustering key value instead of the row identifier (RID). click here » Discuss this question and answer on the forums |

| | | | Darko Martinovic from SQLServerCentral.com Added on 10.4.2017. - .Net source code is available on click here ------------------------------------------------------------------------ When you analyzing blocking problems, first choice is that you look what sys.dm_os_waiting_tasks will display.
It means blocking occurs right now, and you know blocker and blocking spid's.
In that case it is easy to determine resource which is subject of blocking. SELECT
DTL.[resource_type] AS [resource type]
,CASE
WHEN DTL.[resource_type] IN ('DATABASE', 'FILE', 'METADATA') THEN DTL.[resource_type]
WHEN DTL.[resource_type] = 'OBJECT' THEN OBJECT_NAME(DTL.resource_associated_entity_id)
WHEN DTL.[resource_type] IN ('KEY', 'PAGE', 'RID') THEN (SELECT
(CASE
WHEN s.name IS NOT NULL THEN s.name + '.'
ELSE ''
END) + OBJECT_NAME(p.[object_id])
FROM sys.partitions p
INNER JOIN sys.objects o
ON o.object_id = p.object_id
INNER JOIN sys.schemas s
ON o.schema_id = s.schema_id
WHERE p.[hobt_id] = DTL.[resource_associated_entity_id])
ELSE 'Unidentified'
END AS [Parent Object]
,DTL.[request_mode] AS [Lock Type]
,DTL.[request_status] AS [Request Status]
FROM sys.dm_os_waiting_tasks wt
INNER JOIN sys.dm_tran_locks DTL
ON DTL.lock_owner_address = WT.resource_address
WHERE wt.blocking_session_id IS NOT NULL;
But, if you analyzing blocking problems off-line, using trace or extended events, you have to count only on information found in blocked process report.
The resource name is most important information in the blocked process report. Unfortunately this information is only available as encoded.
The purpose of this script is to decode this information. I PART using T-SQL --@waitResource is written in blocked process report as a attribute of blocked-process/process element DECLARE @waitResource as nvarchar(128) = 'KEY: 41:72057594544062464 (b14200e25741)' -- replace this string with your wait resource string
SELECT
DBO.[GetResourceName]( @waitResource, default); -- Will return t-sql to evaluate SELECT
sc.name + '.' + so.name
FROM MYDB_NAME.sys.partitions AS p
JOIN MYDB_NAME.sys.objects AS so
ON p.object_id = so.object_id
JOIN MYDB_NAME.sys.indexes AS si
ON p.index_id = si.index_id
AND p.object_id = si.object_id
JOIN MYDB_NAME.sys.schemas AS sc
ON so.schema_id = sc.schema_id
WHERE p.hobt_id = 72057594098286592 --2. Example. Evaluation DECLARE @waitResource as nvarchar(128)
DECLARE @sql as nvarchar(max)
DECLARE @resCon as nvarchar(256)
SET @waitResource = 'KEY: 10:72057594098286592 (b14200e25741)'
--second parametar name should be the same as
--the name of first parametar in sp_executesql
SET @sql = DBO.GetResourceName(@waitResource, '@resourceName') EXEC sp_executesql @sql
, N'@resourceName nvarchar(max) output'
, @resCon OUTPUT;
SELECT @resCon -- Will return resource name -- II . PART using SQLCLR -- Although it seems that CLR is better solution, there is a limitation when processing PAGE information. -- Clr function does not allwed using dbcc or create temp table. Workaround is to use CLR stored procedure to -- determine resource name SELECT
[dbo].[GetResourceNameClr]('PAGE: 25:1:6077390')
--KEY: 25:72057600909443072 (8b56a42c5bc8)
SELECT
[dbo].[GetResourceNameClr]('KEY: 25:72057600909443072 (8b56a42c5bc8)')
--OBJECT: 25:1239779574:0
SELECT
[dbo].[GetResourceNameClr]('OBJECT: 25:1239779574:0') -- 'PAGE: 25:1:6077390 EXEC [dbo].[GetResourceNameFromPageClr] 25
