Script they use to generate indexes in SQL 2005.
I have 2 databases on a separate instance. I want to script out all indexes from database1 then execute it on database2.
How to accomplish this task efficiently.
We are running SQL Server 2014 Enterprise Edition (64-Bit) on Windows 2012 R2 Standard (64-Bit).
1. When to create indexes, before or after data is added? Please address Clustered and Non-Clustered Indexes.
2. To move indexes to it's own filegroup, is it best to create the NON-Clustered Indexes on the separate filegroup with code similar to the example below?
CREATE NONCLUSTERED INDEX IX_Employee_OrganizationLevel_OrganizationNode
ON HumanResources.Employee (OrganizationLevel, OrganizationNode)
WITH (DROP_EXISTING = ON)
ON TransactionsFG1;
GO
I have read the following links that states that if you create the Clustered Index on a separate filegroup, it would also move the base table to that particular filegroup. (So I take it that you ONLY can move NON-CLustered Indexes to a separate filegroup.)
Placing Indexes on Filegroups:
[URL]
By default, indexes are stored in the same filegroup as the base table on which the index is created. A nonpartitioned clustered index and the base table always reside in the same filegroup. However, you can do the following:
• Create nonclustered indexes on a filegroup other than the filegroup of the base table.
Move an Existing Index to a Different Filegroup:

Limitations and Restrictions
• If a table has a clustered index, moving the clustered index to a new filegroup moves the table to that filegroup.
• You cannot move indexes created using a UNIQUE or PRIMARY KEY constraint using Management Studio. To move these indexes use the CREATE INDEX statement with the (DROP_EXISTING=ON) option in Transact-SQL.
I was reading this blog below about Indexed Views and needed some clarification.
When the author choose to create the unique clustered index he excluded the PER.BusinessEntityID columns and only included, (CustomerID, SalesOrderID, ProductID).
Why didn't the PER.BusinessEntityID get added?
[URL] ....
CREATE VIEW Sales.vSalesSummaryCustomerProduct
WITH SCHEMABINDING
AS
SELECT CUST.CustomerID ,
SOH.SalesOrderID ,
SOD.ProductID ,
SUM(SOD.OrderQty) AS TotalOrderQty ,
[Code] .....
I need to find all the index and the creation date. I did cross apply of sys.objects & Sys.indexes on name column. I am getting some but the team is saying they created so many. Any other option to find Indexes and their creation date?
View 2 Replies View RelatedI'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?
Hi,
Can anybody help me how to Stop this 'System Creation Indexes' (Index Name like 'WA%')?.
Is there any method is available to delete the Existing 'System Indexes'?.
thanks,

Hi All,
In the manual I find the following comment for creating indexes.
"If partition_scheme_name or filegroup is not specified and the table is partitioned, the index is placed in the same partition scheme, using the same partitioning column, as the underlying table."
We are creating some dimensional models in SQL Server with about 100M rows in the largest fact tables.
What I have created are base tables which were on 'primary' and then created a clustered index over a partitioning scheme. I did this as I figured the data will go into the clustered index in any case.
However, when I then create indexes on these tables they do not look like they are petitioned....at least not as far as I can tell.
Q1. Is there some way to tell if the index was partitioned properly?
Q2. If the index is not partitioned is there any simply way to alter the table to the partitioning scheme? My reading of the manual tells me I have to unload, truncate, alter and then reload the table. Is there a better way?
Thanks in advance for your assistance.
Best Regards
Peter
I saw this tool for SQL-Server 2000 :

Is there anything similar for SQL-Server 2005 Express ?
Thank you very much for any help!

If i create a simple table with a foreign key constraint, does itcreate an implicit index on that given ID? I've been told this isdone in some databases, but i need to know for sure if SQL Server doesit. Has anyone heard of this before, on any other databses perhaps?Heres an example of how the foreign key constraint is being added:ALTER TABLE [dbo].[administrators] WITH CHECK ADD CONSTRAINT[FPSLUFSUOXZGAJOJ] FOREIGN KEY([AdministratorRoleID])REFERENCES [dbo].[administratorroles] ([AdministratorRoleID])My initial testing seems to indicate adding an index on the foreignkey column helps, but i need to know for sure. Any insight would begreatly appreciated!Bob

View 6 Replies View RelatedWhat are driving criteria for creating filtered indexes on SQL server. I am trying to analyze the index stats through DMV,histogram and have to analyze if the filtered indexes should be created on tables. This exercise has to be done for all the transaction tables on the database. What are the approaches I should be looking on?
There was a deadlock on the DB because of huge writes on one of the big tables. Having filtered index on this table for the effected column would reduce the time taken for write operations. Hence we are looking for creating filtered indexes appropriately
Looks like SQL decided to make an index, is this typical? Where can I look at the parameters for this? Thanks

Hi,
like I said in other posts, I'm new to sql server, worked with informix for a long time. Right now I got into an "argument" with the present "dba", the indexes for all the tables in the database are being rebuilt, he wanted to start a monthly process, I told him that he can't do processing because when an index is built the table is locked, now, since I'm new at sql server I would like to know from the experts..... can you run process in sql server against tables when:
- indexes are being created
- the structure of a table is being modified
- the database is being shrunk
If we had been talking about informix then I would have probably slapped him if he tried to "teach" me about how things work, I'm pretty sure its the same in SQL but I think its better to have complete assureness of what I'm talking about before the slapping starts :)
Thanks in advance

I have 2 questions,
1. I am trying to create an index, which is running for a long time. Is there an option to know the progress so far or how much more time it is going to take?
2. Is there anyway to find out how much space is required to rebuild an index?

Hi -
I could not find an SQL script, which would generate index creation DDL for a specific table/index. Query Analyzer does it, but I need to do it programmatically. Does anyone have a working script?
Thank you.
Does Microsoft SQL Server keep a record of an index creation date andlast modified date in a system table somewhere?
View 2 Replies View RelatedWe have an SSAS instance where when we run the query "select * from $system.discover_traces" the creation time in the resultset shows a different time from when we actually started the trace.
for example if we have create the trace at 3.30pm it shows 7.35 pm in the Sql server management studio resultset when we run the query "select * from $system.discover_traces".
We need to create a pdf file from SQL server preferably from a stored procedure. Application will call the stored procedure and it should generate pdf. From my research it appears it can be done using various external tools with licensing/costs. But is it possible to do this within sql server database without additional costs? I read that this can be done by SSRS in SQL server but not sure if it is a good solution and if it is additional licensing..

I have a scenario where I have 3 columns and all 3 of them are used in the where clauses of simple queries or ones having joins .
TABLE(
Column1 int
FLAG1 bit
FLAG2 bit
)
Sample queries :
Select * from TABLE where FLAG1 =1 and FLAG2 =0
(Any combination of these flags)
Select * from TABLE inner join SOMEOTHERTABLE on
TABLE.Column1 = SOMEOTHERTABLE .Column1
where FLAG1 =1 and FLAG2 =0
( any join and combination of flags)
Questions :
What would be the best nonclustered index strategy :
Column1 as the index key including FLAG1 and FLAG2
or
Column1,FLAG1 and FLAG2 in the index key
Points to note :
The queries are part of an ETL process and are used to track new records vs old records. The Flags switch states within the same job . So if we are creating an index on all 3 columns, the index has to be reorganized more than once based on the flag states. If we keep them in the include list , then its only about updating the leaf data with the latest flag values.
On the other hand, an index on all 3 columns will result in an index Seek alone , where as for the included list , there will be an index seek and a predicate .
Does the predicate cause more overhead than reorganizing the index or is it the opposite ?

Hi
I'm trying to use a user defined alias type in a table creation, and everything works as expected, right until the moment where I rightclick on [Indexes] and click [new index] to create a new index.
Then I get this error:
TITLE: Microsoft SQL Server Management Studio

------------------------------
ADDITIONAL INFORMATION:
Cannot show requested dialog. (SqlMgmt)

exec sp_executeSql N'CREATE SCHEMA [TestSchema] AUTHORIZATION [dbo]'
GO
CREATE TYPE [TestSchema].[type_TestType]
FROM uniqueidentifier ;
GO
Create table [TestSchema].[Periode3]
(
Periode3_UID uniqueidentifier NOT NULL ROWGUIDCOL,
rowVersion timestamp NULL,
owner uniqueidentifier not null,
validFrom datetime
NOT NULL CONSTRAINT
DF_Periode_modified3 DEFAULT getdate()
);
Alter table [TestSchema].[Periode3]
add PeriodeType [TestSchema].[type_TestType];
now if I replace the 2 last lines with:
Alter table [TestSchema].[Periode3]
add PeriodeType uniqueidentifier;
everything works as expected.
Where did I go wrong ?

I want to write a query to generate a report. I have a date column which will be holding all the business dates. No dates of Saturday and Sunday are allowed. What I am looking for is, I want to get the result of every 5th business day of each month. A month could start with any day. I just want only the 5th business day.

I know there is some key word that you use to force SQL server to generate a new query plan ?What can that be ?
It's often said or done that when inserting or updating into a 'large' table that disabling the non-clustered indexes can is needed for performance.
Now I know the obvious way to find out if this is best or not is by testing the different options. I was wondering if there was a rule of thumb to this?
Say you have a table with half a billion rows and 4 non-clustered indexes and are only updating half a million rows then sometimes disabling every night and re-enabling can take way more time than the actual update. Haven't found an articles advising to disable them when a table is over X rows and you are updating Y% of them...
My index reorganise maintenance plan fails partly due to the disabled indexes
Executing the query "ALTER INDEX [I_ModelSecurityCommon_RECID] ON [dbo]...
" failed with the following error: "Cannot perform the specified operation on disabled index 'I_ModelSecurityCommon_RECID' on table 'dbo. Model SecurityCommon'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I don't want to delete the indexes as they are standard indexes that where on the DB from install.. any script that will reorganise all enabled indexes? and also to rebuild?
Can anyone suggest an appropriate strategy to create unique index's when a distributed database is used. As a bit of a background I have several SQL Server 2005 servers scattered around the country and I am trying to come up with a way to create a unique index i.e. one that hasn't been used in a particular table say Staff in any of the databases around the country.
Performance is an issue particularly as our network isn't that fantastic has anyone done something similar and achieved reasonable speeds?
Thanks ...

Hi,
Does anyone have any good tips for reducing the amount of disk space required for new clustered index creation.
I have just finished building a rather large table (48gbs) and durring the clustered index creation I came very close to running out of disk space.
What I am already doing:
1.Recovery Model simple
2. index padding 0
3. fillfactor 0
Any help would be appreciated

I want to join 2 tables, table a and table b where b is a lookup table by left outer join. my question is how can i generate a flag that show whether match or not match the join condition ?
**The lookup table b for column id and country are always not null values, and both of them are the keys to join table a. This is because same id and country can have multiples rows in table a due to update date and posting date fields.
example table a
id country area
1 China Asia
2 Thailand Asia
3 Jamaica SouthAmerica
4 Japan Asia
example table b
id country area
1 China Asia
2 Thailand SouthEastAsia
3 Jamaica SouthAmerica
5 USA America
Expected output
id country area Match
1 China Asia Y
2 Thailand SouthEastAsia Y
3 Jamaica SouthAmerica Y
4 Japan Asia N
