Right Or Wrong In Index Creation......
Feb 3, 2005
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

Looks like SQL decided to make an index, is this typical? Where can I look at the parameters for this? Thanks

create statistics hind_239_3 on [calljrnl] ( [cj_created_by] )

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.

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 ,

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
------------------------------
Cannot show requested dialog.
------------------------------
ADDITIONAL INFORMATION:
Cannot show requested dialog. (SqlMgmt)
------------------------------
Object reference not set to an instance of an object. (SqlManagerUI)
------------------------------
BUTTONS:
OK
------------------------------
This is the script I use to create the table:
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 ?

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 have a Performance issue in ssrs report , query takes execution time 1 to 2 min. When I add the non clustered index for one of the table columns which takes only 2 sec to execute the query. But as from my environment I couldn't able to add the index due to these changes will effect for all reports. Without adding indexes which takes 2 min to run that report. My question is:
Is there any way to add the non-clustered index on the report itself like if a non clustered index exists "execute the query" else create a non clustered index and run that report with newly created index in report itself like a temp table concept. How to add this concept in this below query:Final Query without non clustered index, takes 2 min to execution time ---

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:
[URL]
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.

Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error.

We 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".

I 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.

Dear All.
We had Teradata 4700 SMP. We have moved data from TD to MS_SQL SERVER 2003. records are 19.65 Millions.
table is >> Order_Dtl
Columns are:-
Client_ID varchar 10
Order_ID varchar 50
Order_Sub_ID decimal
.....
...
..
.
Pk is (ClientID+OrderId+OrderSubID)
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.
In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.
I am thank u to all who read or reply.

Should i create index for category1 and category2 and category3 ? But i dont know create index.. My select code lines is below.. Could you learn me and show me index for it ?? or Could you learn me and show me fast Select code lines and index or etc ???

Hi,
I'm running a merge replication on a sql2k machine to 6 sql2k subscribers.
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'.
All DBCC CHECKDB command's return 0 errors :confused:
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?

Hi 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

I 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?

Quick question about the primary purpose of Full Text Index vs. Clustered Index.
The Full Text Index has the purpose of being accessible outside of the database so users can query the tables and columns it needs while being linked to other databases and tables within the SQL Server instance.
Is the Full Text Index similar to the global variable in programming where the scope lies outside of the tables and database itself?
I understand the clustered index is created for each table and most likely accessed within the user schema who have access to the database.
Is this correct?
I am kind of confused on why you would use full text index as opposed to clustered index.
Thank you

Hi All,
I 'm working to improve some sql performance.
One of the major syntax inside the SELECT statment is ..
WHERE FIELDA IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='A') AND
WHERE FIELDB IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='B') AND
WHERE FIELDC IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='C') AND
WHERE FIELDD IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='D') AND
WHERE FIELDE IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='E') AND
WHERE FIELDF IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='F')
(It's to compare the field content with some user input parameter inside a parameter table... )
I think properly is that the SELECT ... IN is causing much slowness in the sql statement. I have indexed FIELDA , FIELDB, FILEDC etc and those PARAVALUE and PARATYPE in the PARATABLE table. But perfromance is still slow and execution takes >20 seconds for 200000 rows of records.
Do any one know if still any chance to improvide the performance like this?
Much Thanks,
Andy

I'm trying to find whether there is a dmv or system view that can help me see the last time an index was rebuilt or created. Assuming I rebuilt an index using tsql commands (not a job with a history), is there a way to find out the last time that index was rebuilt?
Thanks much.

I have a really strange problem.
I execute this query:
declare @cid int
set @cid = 2003227
select * from sales s, product p where p.product_Id = s.product_Id and customer_id = @cid
select * from sales s, product p where p.product_Id = s.product_Id and customer_id = @cid or @cid = 0
3 Million rows in sales, 120000 in product.
The first does and index seek, the second an index scan.
The execution plan reports that the scan takes 99.87% of the cost, and the seek takes 0.13%
This problem obviously gets worse the bigger the dataset / query /etc.
The reason I query this, is because it never used to take this long to do index scans. Is there something i can change, something i can fix?
Any help would be appreciated.
