Issue With Scripting The Index Of A Table
Nov 1, 2007
Hi
Im working on SQL Server management Studio with SQL Server 2005.
If I run the following script, which is being generated by the scrip option of my machine, I'm getting this error. I just can't understand the reason beyond this.
CREATE CLUSTERED INDEX [PK_Employee_EmployeeID] ON [HumanResources].[Employee] ([EmployeeID] ASC)
WITH (PAD_INDEX = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = ON) ON [PRIMARY]
GO
Msg 170, Level 15, State 1, Line 3
Line 3: Incorrect syntax near '('.
And if I remove the second line and ececute,it is working fine as follows.
CREATE CLUSTERED INDEX [PK_Employee_EmployeeID] ON [HumanResources].[Employee] ([EmployeeID] ASC)
--WITH (PAD_INDEX = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = ON) ON [PRIMARY]
GO
Command(s) completed successfully.
Can anyone help me in predicting the reason beyond this??
Thanks

Hi,
Does anyone have scripts that generate the following:
1. All PK
2. All FK
3. All Indexes
Separate from the table DDL.
( EM can generate but with table DDL as well )

Hi to all
Is there any option in sql server DTS or any other third party tool that can script data. By scripting data i mean that....
if a table "Employee" contains 50 rows, i want the tool to write 50 insert queries for me so that i can run in it anywhere.
Problem is i have to insert data in a remote server where i cannot use DTS. I just have a text area to write my query and press the run button..
Hope u understand my problem. In case of any explanation please reply. Waiting for your response. Thanx in advance.
by to all

Can anyone provide with an example of how to script a profiler trace to have the data wind up in a SQL Table. The scripting mechnism that comes with SQL Server will not allow you to put the results in a table.
Thanks

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 setup a DTS job that performs the following steps once a week.
1. Truncate a User Table called Sales
2. Import 750,000 new sales records from a semi-colon delimited text file.
3. Execute an update query that adds a SalesID field to each record. (this is a concatenation of several columns for each record and may not be unique)
This whole process takes about 2 minutes.
Here is my question: all querys and views against this Sales table use the SalesId field to identify a result set. Therefore my thought is that I need Clustered index on the SalesID field in the sales table.
What is the right way to handle this:
1. Leave the table as is and do not add an index to the SalesID field. (All queries would rely on file scan of the table)
2. Add a permenat Index to the SalesID field. Which will probably cause the truncate and Import to run more slowly.
3. Do option 2 but drop the index before truncating the table and add the Index back to the SalesId field as the last step in the DTS job.
Any idea what would provide the best performance? If I missed any options please let me know, thank you for any help!

When considering locks caused by a table, would it be better to have more rows in a table
than less? For example, I can design the table to hold 1 million rows that have 300,000 rows that are
updated frequently or I can take out 700,000 rows and place them in another table and have
the 300,000 rows that remain take a severe beating. Would I have less locking problems and
deadlocks if I take out the non-updating rows or would it be more likely to deadlock because
of a higher chance of a lock being held on the same page?
Thanks,
Mike

I have a tmp table created as
select row_number() over ( order by duedate) as row ,
duedate as date, ...
into #fronta
from oitb with(nolock)
where ....
order by duedate
The table is filled correctly with about 30k records. Now in next step I want to work with this tmp table I created, but I have problem, when I use query like this
select * from #fronta where row < 500
When the operator is = or <>, the query is quick, but when I use < or >, the query takes about 10 minutes.
I tried to add to this tmp table index on field named row, but with no succes.
Have anyone idea how to improve the speed?
thanks a lot

Hello,
I have a table as so:
ID
Field1
Field2
Field3
My ID field is an identity field (unique). It is the primary key. I also want to add an index/unique key so that a combination of Field1 and Field2 can not be duplicated. How do I do this?
Many thanks in advance!

Hi I'm issuing a SELECT on a field with the SUM on SQL Server 7. I have an index on the field in the WHERE clause but upon analysis, the Query Optimizer always uses a Full Table Scan. Can anyone explain why and is there a way to use the index.
HEre's the structure:
SELECT SUM(colA)
FROM TABLE tblB
GROUP BY colC
An index exists on column colC.
Thanks

I am creating a table variable (@tblBin) to temporarily store a set of data. Later in my sproc, I am doing a JOIN from @tblBin to a persistent table. In order to improve performance, I was thinking of adding an index to the columns of the @tblBin (indexes already exist on the persistent table). Using standard CREATE INDEX syntax(*), I am getting a compile error. Can this be done?
(*)CREATE NONCLUSTERED INDEX IX_tblBin_shortname ON @tblBin(shortname)
TIA ...

I already posted this over on sqlteam so don't peek there if you haven't seen that post yet. :)
So now to the question:
Anyone care to guess how long it took me to build a clustered index on a table with 900 million rows? This is the largest amount of data in a single table I have had to work with thus far in my career! It's sorta fun to work with such large datasets. :)
Some details:
1. running sql 2005 on a dual proc 32bit server, 8gb ram, hyperthreaded, 3ghz clock. disk is a decent SAN, not sure of the specs though.
2. ddl for table:
CREATE TABLE [dbo].[fld](
[id] [bigint] NOT NULL,
[id2] [tinyint] NOT NULL,
[extid] [bigint] NOT NULL,
[dd] [bit] NOT NULL,
[mp] [tinyint] NOT NULL,
[ss] [tinyint] NOT NULL,
[cc] [datetime] NOT NULL,
[ff] [tinyint] NOT NULL,
[mm] [smallint] NOT NULL,
[ds] [smallint] NOT NULL
)
3. ddl for index (this is the only index on the table):
CREATE CLUSTERED INDEX [CIfld]
ON [dbo].[fld]
(
extid asc
)WITH (FILLFACTOR=100, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF)
4. extid column was not sorted to begin with. ordering was completely random.
Note that I have changed the column names, etc, to protect the innocent. I can't go into details about what it's for or I'd be violating NDA type stuff.

I have a table that has thousands of rows inserted daily (rows are seldom updated or deleted)
The table is also involved in frequent non-simple select statements. It currently has about a million rows.
Out of the 15 odd columns in the table, I can see about 6 that would benefit being indexed to speed up the select statements.
Before I do this, I was wondering if people think that perhaps I should create an indexed view that all select statements use, rather than adding indexes directly to the table.
Can anyone advise me the performance benefits/disadvantages of indexed views over indexed tables?
Thanks

On one of those common interview question lists, there is the question:
How do you know which index a table is using?
The two answers that I've found are:
SELECT * FROM user_constraints
--and
SELECT TableName,IndexName FROM user_constraints
Both of these return the error:
Server: Msg 208, Level 16, State 1, Line 1
Invalid object name 'user_constraints'.
Is this because I'm using the free version of 2000(MSDE)?
If so, what is the right answer for this version?
-Thanks

Hi,I've got 2 table variables inside of an SQL 2000 function:@tmpBigList(BItemID, BRank)@tmpSmallList (ItemID, Rank)The following UPDATE statement can run for a long time if @TmpTable1has 500 rows and @TmpTable2 has 35,000 rows.UDPATE @tmpBigListSET BRank = t.RankFROM @tmpBigListJOIN @tmpSmallList t on t.ItemID = BItemIDLooking at the Query Plan, you see that the INNER JOIN Of @tmpBigListto @TmpSmallList results in 500 * 35,000 = 17,500,000 rows beingreturned from @TmpSmallList. That takes a long time.An index would help, but it appears that you can't add an index to atable variable.Changing to a temp table does not work since it's in a function.Thanks,Joe Landes

We had data in tables for multiple users (Logins) .Each user data is identified by a one column named €œUSER€?. No user has direct access to tables and only through views .we have created views and stored proc .Views will perform DML operations on tables using condition WHERE USER=SUSER_SNAME() (i.e Logged in user).So no point of getting others user data.
Each table has a column USER and we are queering data based on login user .this is the foreign key of USER table. Each view contains user column in where clause .So for every query we are searching all records .instead of that is there any way to get data with out searching all records.
I heard about table Partitioning, index Partitioning, view Partitioning. Are they helpful to boost my query performance?
And also let me know is there any good way of designing apart from above options
