Minor and inconsequential but sometimes you just gotta know:
Is it possible to define a non-primary key index within a Create Table statement? I can create a constraint and a PK. I can create the table and then add the index. I just wondered if you can do it in one statement.
e.g. I have:
CREATE TABLE MyT
(MyT_ID INT Identity(1, 1) CONSTRAINT MyT_PK PRIMARY KEY Clustered,
MyT_Desc Char(40) NOT NULL CONSTRAINT MyT_idx1 UNIQUE NONCLUSTERED ON [DEFAULT])
which creates a table with a PK and unique constraint.
I would like (pseudo SQL):
CREATE TABLE MyT
(MyT_ID INT Identity(1, 1) CONSTRAINT MyT_PK PRIMARY KEY Clustered,
MyT_Desc Char(40) NOT NULL CONSTRAINT MyT_idx1 UNIQUE INDEX NONCLUSTERED ON [DEFAULT])
No big deal - just curious :D Once I know I can stop scouring BOL for clues.

Hi all as i remember i had read in Books Online that on each Table in Sql Server we can create only one Clustered index but today suddenly i create another clustered index on a table without any Error from SQl server !!! BUT my query Order changed to the order of this newly created index. could anyone elaborate on this issue?
SQL Server 7/2000: We have reasonably large tables (3,000,000 rows)that we need to add some indexes for. In a test, it took over 12 hoursto CREATE a new INDEX against this table. One of us suggested that wecreate a temp table with the new index and copy the data from the oldtable into the new one, then rename it. I understand this took 15minutes. Why the heck would it be faster to move the data and buildmultiple indexes incrementally vs adding an index??
I am in poduction Support,I have scenario I have to drop the Index .....and ....Create index(cluster and non-cluster) on a table. will Create index take table off line.
I 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. The job ran for about 20 hours into it and then fails with error: "Out of disk space in tempdb". My tempDB size is 1.8TB, but yet it's still not enough.
Here is my script:
CREATE CLUSTERED INDEX CI_IndexName ON TableName(Column1,Column2) WITH (MAXDOP= 4, ONLINE=ON, SORT_IN_TEMPDB = ON, DATA_COMPRESSION=PAGE) ON sh_WeekDT(Day_DT) GO
I am trying to run an SELECT statement with a CONTAINS statement from a aspx.net solution built using Visual Web Developer 2005 express edition. When I try to run the thing it throws an error saying
"Cannot use a CONTAINS or FREETEXT predicate on table or indexed view 'JournalArticle' because it is not full-text indexed.".
I don't have access to the SQL Express server, I interface through Server Management Studio Express. There is an option to create a full-text index from the menu, but it is greyed out, presumably because there is no full-text catalogue. This is my real question, How do I create a full-text catalogue using Server Management Studio Express? The help function only provides examples of sql code, which I assume must be performed using sql server (which I don't have access to). Any help would be greatly appreciated.
my stored procedure have one table variable (@t_Replenishment_Rpt).I want to create an Index on this table variable.please advise any of them in this loop... below is my table variable and I need to create 3 indexes on this...
i have created a fact table which has unique cluster index as below,
CREATE UNIQUE CLUSTERED INDEX [FactSales_SalesID] ON [dbo].[FactSales] (salesid ASC) WITH (DATA_COMPRESSION = PAGE) GO however later when i add CLUSTERED COLUMNSTORE INDEXES : CREATE CLUSTERED COLUMNSTORE INDEX CSI_FactSales ON dbo.FactSales WITH (DATA_COMPRESSION = COLUMNSTORE) GO
it prompts error.
Msg 35372, Level 16, State 3, Line 167 You cannot create more than one clustered index on table 'dbo.FactSales'. Consider creating a new clustered index using 'with (drop_existing = on)' option.
I want to create index for hash table (#TEMPJOIN2) to reduce the update query run time. But I am getting "Warning!
The maximum key length is 900 bytes. The index 'R5IDX_TMP' has maximum length of 1013 bytes. For some combination of large values, the insert/update operation will fail". What is the right way to create index on temporary table.
Update query is running(without index) for 6 hours 30 minutes. My aim to reduce the run time by creating index.
And also I am not sure, whether creating index in more columns will create issue or not.
Attached the update query and index query.

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 desire to have a clustered index on a column other than the Primary Key. I have a few junction tables that I may want to alter, create table, or ...
I have practiced with an example table that is not really a junction table. It is just a table I decided to use for practice. When I execute the script, it seems to do everything I expect. For instance, there are not any constraints but there are indexes. The PK is the correct column.
CREATE TABLE [dbo].[tblNotificationMgr]( [NotificationMgrKey] [int] IDENTITY(1,1) NOT NULL, [ContactKey] [int] NOT NULL, [EventTypeEnum] [tinyint] NOT NULL,
I have a text file which needs to be created into a table (let's call it DataFile table). For now I'm just doing the manual DTS to import the txt into SQL server to create the table, which works. But here's my problem....
I need to extract data from DataFile table, here's my query:
select * from dbo.DataFile where DF_SC_Case_Nbr not like '0000%';
Then I need to create a new table for the extracted data, let's call it ExtractedDataFile. But I don't know how to create a new table and insert the data I selected above into the new one.
Also, can the extraction and the creation of new table be done in just one stored procedure? or is there any other way of doing all this (including the importation of the text file)?

if i create one index how it works
where should i create index please write one index for me
Recently we are having issues with one of the indexes during our maintenance. There is one index that which usually would have taken 10-15 mins continues to run even after 3 hrs. Other indexes on the same table finish nicely. Just this one gets stuck. Our index creation scripts drops existing index and creates new one..
CREATE INDEX ... ON ... WITH DROP_EXISTING, SORT_IN_TEMPDB ...etc
So last week when I got woken up because of this, I tried to drop the index explicitly and re create the index (by removing the DROP_EXISTING in above script). Even though it took about 45 mins it still finished in time during the maintenance window.
We had the same issue this week. I was looking at sp_who2 during the index creation, I noticed very low CPU activity and high DiskIO. example: CPU : 4k cycles, DiskIO 50000.
There is 20% of free space on the index file group. Generally index creation takes higher CPU and lower DiskIO.
How do I find out what the issue is with this index? The table has 40 million rows. this is a non-clustered index. There are 2 other indexes on the table - one clustered. they both finished properly in less than 10 mins.
How to create index when there is a SQL statement like Select count(1) as [Total], sum(Case when Field1 < Field2 then 1 else 0 End) as [Selected] from Table1
I am trying to create an index on a view that joins two tables.
I get the classic error of course: 'Cannot index the view 'dbname.dbo.HJC_net'. It contains one or more disallowed constructs.'
Thing that gets me is that it all seems pretty normal stuff and I can't see what is stopping it.
Code is below and any help greatly appreciated.

I was asked to import some data from excel into a table within a sqlserver 2000 db the import was complaining about an index so then I deleted the index imported the data succesfilly but I'm now unable to re create the index, please see the error that I'm getting below. Can someone please help. Thanks
- Unable to create index 'trainingGo'. ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 32. Most significant primary key is '439'. [Microsoft][ODBC SQL Server Driver][SQL Server]The statement has been terminated.
Are Primary Key fields automatically indexed, or do you have to create a seperate index for a PK in order for it to be indexed? I'm using SQL Server 2005.
Hi, all, I want to re-create an index on a production table. I got an error 644 "could not find index entry...". The DBCC CHECKDB and CHECKTABLE gave me this:
Server: Msg 8928, Level 16, State 1, Line 1 Object ID 37575172, index ID 6: Page (1:939782) could not be processed. See other errors for details. Server: Msg 8939, Level 16, State 1, Line 1 Table error: Object ID 37575172, index ID 6, page (1:939782). Test (*(((int*) &m_reservedB) + i) == 0) failed. Values are 7 and 36. DBCC results for 'Mfg_DFSFNSF'. There are 1142314 rows in 326143 pages for object 'Mfg_DFSFNSF'. CHECKTABLE found 0 allocation errors and 2 consistency errors in table 'Mfg_DFSFNSF' (object ID 37575172).
The table script for the index is like this:
CREATE UNIQUE INDEX [Mfg_ITMDH_MbrIdx] ON [dbo].[Mfg_DFSFNSF]([_ITMDH_OwnRow], [_ITMDH_MbrKey], [RECTYPE]) WITH FILLFACTOR = 70 ON [PRIMARY]
My question is that can I drop it and run above create it to fix the problem in live mode?
I know the other option will be: DBCC CHECKTABLE (FSDBMR.dbo.Mfg_DFSFNSF, repair_allow_data_loss) But that has to put the db under single user mode.
Hi guys. I have a table named [Check] and need to create an index for CVNumber field. The table has no primary key for the meantime. I tried this script but error occured.
BEGIN TRANSACTION SET QUOTED_IDENTIFIER ON GO SET TRANSACTION ISOLATION LEVEL SERIALIZABLE GO COMMIT BEGIN TRANSACTION CREATE NONCLUSTERED INDEX IX_Check_1 ON dbo.[Check] ( CVNumber ) ON [PRIMARY] GO COMMIT
Error message:
Server: Msg 3023, Level 16, State 2, Line 3 Backup, CHECKALLOC, bulk copy, SELECT INTO, and file manipulation (such as CREATE FILE) operations on a database must be serialized. Reissue the statement after the current backup, CHECKALLOC, or file manipulation operation is completed. Server: Msg 3902, Level 16, State 1, Line 1 The COMMIT TRANSACTION request has no corresponding BEGIN TRANSACTION.
Is it because I used the table name Check which is a reserved word for SQL? But I included [ ].
I have a view on the table. The Output of the view is PID, Postcode, ADDRESS (which is Address1 - Address5 concatenated into one string with spaces between notnull values)
I use a sproc to search the view for an address based on a free-text search. Sproc as below. Can anyone advise how I should index the table? I have never created an index before and need to speed up the search, which at the moment is simply to slow. I have 1.8 million records in the table.
Here is the sproc:
SELECT PID, Upper(Postcode) as 'Postcode', ADDRESS FROM vw_Postcode
WHERE Address Like '%' + REPLACE(REPLACE(@address,',','%'),' ','%') + '%' OR Postcode Like '%' + REPLACE(REPLACE(@address,',','%'),' ','%')+ '%'
