CREATE INDEX On Large Table
Jul 23, 2005
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 hours
to CREATE a new INDEX against this table. One of us suggested that we
create a temp table with the new index and copy the data from the old
table into the new one, then rename it. I understand this took 15
minutes. Why the heck would it be faster to move the data and build
multiple indexes incrementally vs adding an index??

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

Other than right-clicking on each individual table in SSMS and generating a CREATE script, is there a simple way to generate CREATE TABLE scripts for tables within a given database?
Background: I have a bunch of tables in one database, and I would like to add tables to a second database that have the same names and basic structures of some of the tables from the first database.
I do not need to transfer any data from the tables, this is a seperate project that will use a similar data structure. I just want to generate the CREATE TABLE scripts for 30ish tables within the first database, and then I'll tweak the scripts as appropriate and run them against the new database.

I have a master table containing details of over 800000 surveys made up of approximately 400 distinct document names and versions. Each document can have as few as 10 questions but as many as 150. Each question represents one row.
My challenge is to create a separate spreadsheet for each of the 400 distinct document names and versions containing all the rows and columns present in the master table. The largest number of rows would be around 150 and therefore each spreadsheet will not be very big.
e.g. in my sample data below, i will need to create individual Excel files named as follows . . .
"Document1Version1.xlsx" containing all the column names and 6 rows for the 6 questions relating to Document 1 version 1
"Document1Version2.xlsx" containing all the column names and 8 rows for the 8 questions relating to Document 1 version 2
"Document2Version1.xlsx" containing all the column names and 4 rows for the 4 questions relating to Document 2 version 1
I assume that one of the first things is to create a lookup of the distinct document names and versions assign some variables and then use this lookup to loop through and sequentially filter the master table data ready for creating the individual Excel files.
--CREATE TEMP TABLE FOR EXAMPLE
IF OBJECT_ID('tempdb..#excelTest') IS NOT NULL DROP TABLE #excelTest
CREATE TABLE #excelTest (
[rowID] [nvarchar](10) NULL,
[docName] [nvarchar](50) NULL,
[Code] .....
--Output
rowIDdocNamedocVersionquestionblankField

Hi 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. Tks in advance

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.
cheers,

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.

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.

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.

Anyone using the ONLINE=ON option on large DB's? We have a db of 5 GB and we are doing some load testing for SQL 2005. We are modifying the Index scripts for the upgrade. We will run a load with the ONLINE=ON option but just wanted to find out if anyone already is doing it on a similar scale db and has seen any issues?
Also, we have auto-update stats off at the DB level. Does setting the ONLINE=ON require turning this auto-update stats to ON too? I didnt see anything to that effect in BOL, so was wondering.
Thanks for any feedback.

What is the best procedure/sequence to reduce some tables containing large number of rows of
a SQL 2000 server?
The idea is first to check which tables grow extremely fast (all statistics, user or log tables), reduce the table
according to the number of months the user wishes to keep in the table.
As a second step backup remaining rows of table as txt files on harddisk (using DTS), UPDATE STATISTICS and re-indexing reduced table.
Run DTS Package every month once (delete oldest month and backup newest month) and do the same as above to keep size of tables adequate.
What is a fast way to reduce number of rows of a large table - the following example produces an error (timeout expired) of my
ADO connection when executing:
SET @str = 'DELETE FROM ' + @ProcessTable + ' WHERE ' + @SelectedColumn + ' < DATEADD (m,' +' -' +
@KeepMonthsInDatabase + ',
+ GETDATE())'
EXEC (@str)
Adding ConnectionTimout = 0 did not help unfortunately.
What is the best way to re-index the table just maintained?
Thanks

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,

Would it be difficult to write code that would determine the lag values. The lag value is based on the date value.

I created columnstore index on the table with 20 columns and about 1000 000 000 rows
every day added about 5M rows
"select" queries became faster because of batch mode and table demand less disk space then before
I have also 6 similar tables with 5 000 000 000 rows and plan to move them on columnstore index
server has 128 G RAM
What pitfalls I could face if I will have so many columnstore indexes on one server?
How a could see problems in DMV?

We have a table to 100M rows and up until now we were fine with an non clustered index a varchar(4000) because we never went above 900 bytes (yes it is a bad design).We have the need to support international character sets now so the column was updated to nvarchar(4000) and now we have data past the 900 byte limit.
The data is long, seems useless but is needed by the business and they need to be able to search "where bigcolumn like 'test%'". With an index, even with a huge amount of data, it was 'fast'. Now of course without an index it is unusable. The wildcard is always at the end of the search. I made a full text index on the column and basic queries such as: select * from ourtable where contains(bigcolumn, 'AReallyLongStringofTextHere') works fine unless there is a space in the data. We loose thousands of returned rows because of spaces in the data.
I have tried select * from ourtable where contains(bigcolumn, '"AReallyLongStringofTextHere that includes spaces"') but not all of the data is returned. I get 112 rows with the contains statement. The table scanning statement of "select * from ourtable where bigcolumn like 'AReallyLongStringofTextHere that includes spaces%' returns 1939 rows.I understand that a full text index is breaking the long string up since it contains spaces. Is there a way to retain the entire string as 1 index entry or is there a way to fix my query to return all of the rows?

Hello,
I created a SSIS solution for reading data from dbase and storing them in SQL Server. In a ForEachDirectory-Loop up to one thousand dbase files are read and stored. The system where the packages are running has 16 GB RAM.
For the first few hundred dbase files everything goes fine, but then, the RAM seems not to suffice any more and a temp file is created (I changed the path in BufferTempStoragePath).
How can it be that there is a need to create temp files if there is so much RAM available?
Why is the RAM filled more and more during the SSIS package execution?
Is there anything I can do to release some of it? (it is running in a loop and there is no need to store all the data)
Could it be caused by dbase?? (I use Microsoft Jet 4.0 OLE DB Provider)
Another thing is that the temp file is not stored in the path I set in BufferTempStoragePath.
There are sufficient permissions set, but temp file is still created in user temp folder...
Any kind of help is very much appreciated!
Best Regards,
Stefan

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 need to create script that will import large XML files (500 - 7GB) on a daily basis and store the data in a relational db structure.
What is the best and fastest way of importing such files. I have played around with smaller files and found the following.
1. SSIS XML Data Source: It doesn't seem to like the complex elements types and throws out the file.
2. Using Bulk File Import, sorting the file in XML variable and using XQuery to parse the file: This works but it can't take a file more than 2GB in size, so I can't use this method.
3. C# + XML Serialization: This also works, but seems to be terribly slow. I open the DB connection once, so it doesn't open and close for each db call, but still seems like it takes a long time.
how to import large XML quickly in a relational table structure?

Hi all
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.
Thanks in advance,
Don

I need to check if an index available on table T1 and field F1. If not, create a non-clustered on F1. How can I do this in a stored procedure?
