SQL 2012 :: Include Columns In Index That Are In Where Clause / Select List And Join
Jun 2, 2014Usually it is better to include the columns in the index that are in where clause, select list and join.I am thinking that the columns in the selected list is better to keep as index columns and the columns that are in the where clause is better to keep in key columns.Where do we use join column is it better to create as main key column or included column.

Jul 16, 2015We noticed a deadlock 3-4 weeks ago on a table (table1) and deadlock graph was captured.
When I am analyzing the deadlock graph, page number using DBCC PAGE, I am getting the object id for a different table (table2). But deadlock graph shows the name of the object as table1.
Is it possible that subsequent defragmentation of indexes would have caused the respective page id to got re-allocated to a different table? I checked the deadlock graph lately only after 3-4 weeks.
SQL 2012 :: Can Add Index To Table Type
Jun 23, 2015This is my table type definition ( below ) and as you see I declared a table whose name is in @t

SQL 2012 :: PDF Not Found In FT-Index On File Table
Dec 15, 2014I have a filetable and use a statement like
SELECT [name],file_stream
FROM dbo.Inkoopfacturen
WHERE FREETEXT(file_stream, 'Factuur');
It will return the text found in a .pptx but not in a pdf. There are no errors in the FT-log. It tells me that the FT-index is succesfully build.
I have downloaded the iFilter for Adobe (installed it in a folder with a short name), set the temp variable to the bin folder of the installation.
I've executed the following queries:
EXEC sp_fulltext_service 'update_languages';
EXEC sp_fulltext_service 'load_os_resources', 1;
EXEC sp_fulltext_service 'restart_all_fdhosts';
Exec sp_fulltext_service 'verify_signature', 0
When I run the following statement, it'll show pdf in the resultset.
SELECT * FROM sys.fulltext_document_types order by document_type
Still, content is not found.

SQL 2012 :: Create Clustered Index On A Very Large Table (500 GB)
May 7, 2014I need to create a Clustered Index (CI) on a very large SQL Server 2012 database table. This table has about approximately 10 billion rows, 500 GB in size.

Jun 3, 2014I was under impression that rebuilding index online largely means that the index will remain available for use during rebuild and my procs and query will be able to use it during rebuild. Also my understanding was that table will be locked very briefly while the schema change will be completing.But when I was rebuilding the clustered index online on a large table with some 3 million records, the table got locked and I was not able even to read the data from it for some 5 minutes. Then I cancelled the operation as it was production server and it was one of our main transaction table.
Is rebuilding index online supposed to work this way? The table has no other index.The parameteres I used are:
REBUILD WITH (PAD_INDEX = ON, SORT_IN_TEMPDB = ON, ONLINE = ON, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 95)

SQL 2012 :: List All Different Values That Go With Single CAS ID To Appear As Comma Separate List
Jun 15, 2015So at the moment, I don't have a function by the name CONCATENATE. What I like to do is to list all those different values that go with a single CASE_ID to appear as a a comma separate list. You might have a better way of doing without even writing a function
So the output would look like :

preop.Case_ID,

SQL 2012 :: Full Text Index How To Make It NOT To Index Embedded Or Attached Documents
Sep 30, 2015I am using Full Text Index to index emails stored in BLOB column in a table. Index process parses stored emails, and, if there is one or more files attached to the email these documents get indexed too. In result when I'm querying the full text index for a word or phrase I am getting reference to the email containing the word of phrase if interest if the word was used in the email body OR if it was used in any document attached to the email.
How to distinguish in a Full Text query that the result came from an embedded document rather than from "main" document? Or if that's not possible how to disable indexing of embedded documents?
My goal is either to give a user an option if he or she wants to search emails (email bodies only) OR emails AND documents attached to them, or at least clearly indicate in the returned result the real source where the word or phrase has been found.
SQL 2012 :: Clustered Index Key Order In NC Index
Mar 5, 2015I have a clustered index that consists of 3 int columns in this order: DateKey, LocationKey, ItemKey (there are many other columns in this data warehouse table such as quantities, prices, etc.).
Now I want to add a non-clustered index on just one of the other columns, say LocationKey, like this:
CREATE INDEX IX_test on TableName (LocationKey)
I understand that the clustered index keys will also be added as key columns to any NC indexes. So, in this case the NC index will also get the other two columns from the clustered index added as key columns. But, in what order will they be added?
Will the resulting index keys on this new NC index effectively be:
LocationKey, DateKey, ItemKey
OR
LocationKey, ItemKey, DateKey
Do the clustering keys get added to a NC index in the same order as they are defined in the clustered index?

Since a few day's only one of the merge agents fail's with the following error:
The merge process could not retrieve generation information at the 'Subscriber'.
The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.

I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .
Any ideas as to what is causing this error?
Advantages Of Using Nonclustered Index After Using Clustered Index On One Table
Jul 3, 2006Hi everyone,
When we create a clustered index firstly, and then is it advantageous to create another index which is nonclustered ??
In my opinion, yes it is. Because, since we use clustered index first, our rows are sorted and so while using nonclustered index on this data file, finding adress of the record on this sorted data is really easier than finding adress of the record on unsorted data, is not it ??
Thanks

SQL Server 2012 :: Get List Of Last Non Null Values
Feb 10, 2014I have two tables, a dates table and a values table. They are joined on the date column.The date table has a range, say from today as far as 20 days from now, incrementing by 1 day each row.The values table may have a row for a day, and may not. If the day has a value I want to display that value.If the day does not have a value in the values table I want to display the last known value.
I think this can be done with windowing functions in a set based manner but have not been able to work it out. I have done it procedurally but im not happy with that at all, and really want to see if this is possible in a set based manner.Below is some simplified code to allow testing with sample data.
create table DimDate

[code]....
So now I need to query the table @t4 in and to determine the items that are assigned to category 'WHITE' in master category 1 and to 'CIRCLE' in master category 2.The important thing is to return items that are assigned solely to 'WHITE' in master cat 1 and solely to 'CIRCLE' in master cat 2.In the above example it would be only the ITEM 1 (id=10) that is returned:
1. ITEM 2 (id=11) is not returned because it has the assignment to category 'SQUARE' in master cat 2 additionally
2. ITEM 3 (id=12) is not returned because it has the assignment to category 'BLACK' in master cat 1 additionally
3. ITEM 4 (id=13) is not returned as it does not have assignment to category 'CIRCLE' in master cat 2 but only to 'WHITE' in master cat 1
3. ITEM 5 (id=14) is not returned as it does not have assignment to category 'WHITE' in master cat 1 but only to 'CIRCLE' in master cat 2
