We are using an application that stores it's data in SQL Server 2005. The application manages the creation of all it's own objects, including indexes. I would like to migrate the index data to a new filegroup, but there is no place in the application to specify how it builds it's indexes. I assume the indexes are created without specifying a filegroup so the default Primary is used. So, I'm wondering if there is a database option somewhere that you can set the default filegroup for index data?
If not, the only way I can think of accomplishing this goal is through DDL triggers to capture Create Index and Create Table statements and overwrite the Filegroup there.
Server: Msg 1105, Level 17, State 2, Line 2Could not allocate space for object '(SYSTEM table id: -276436763)' indatabase 'TEMPDB' because the 'DEFAULT' filegroup is full.this error occured during dbcc checkdb the total size of the file we aredoing on is [81GB].what is the next step we need to takewe increased about 3699.mb in temp dboverall we have 8 databases in our serveranyone help would me much appreciated.Thanks,pardhi--Message posted via http://www.sqlmonster.com
This is for SQL2k5. The database may be small or big, I don't know (it's going out to multiple customers). I'm wondering if in general it's considered "better" to create a single non-primary default filegroup and put all the objects there, or just leave everything in primary? In one training years back I got the impression that recovering the primary filegroup was important for certain restore operations, so it was always wise to separate them like this.
Hi, I want to replace the indexes in my database to a different filegroup. How can I do that using T-SQL? I only found a way that uses the EM, but I have a lot of indexes and I hate to do it manually.

I have an PK Clustered index that I would like to move to another filegroup, which will inturn reside on another drive. Can someone point me to sql tsql or somewhere on bol that has the step by step on how to accomplish this? Thanks in advance.
I need to load a table with 820,000 records from a Sybase db via DTS. It always fail with the error: "Error at destination for row number 820000. Could not allocate space for object in tablespace tempdb . The default filegroup is full.".
There is only the primary filegroup defined in the db. I've increased the size from 1.5GB to 2GB, and specify that it shd grow automatically by 10% and there's no limit to the size. There is still some 28GB in the server, so it should be fine.
It still fail so I added another file to the primary filegroup with size 100MB. Again, it failed with the same error msg.
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.
is there a setting that will ebnable uniform extent allocation uponcreation of index/table by default ?if there isn't any default setting can you code it in?thanks,Doron
please explain the differences btween this logical & phisicall operations that we can see therir graphical icons in execution plan tab in Management Studio
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.
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.
My SSIS package is running very slow taking so much time to execute, One task is taking 2hr for inserting 100k records, i have disabled unused index still it is taking time.I am rebuilding/Refreshing indexes and stats once in month if i try to execute on daily basis will it improve my SSIS Package performance?
hello, ihave atablelike this - z uniqueidentifier a varchar(40) b varchar(40) c varchar(40) d varchar(40) e varchar(40) f text g image
I am asked to split this table into 2 filegroups and move text and images on to one and other stuff on one. I am new to MS-SQL 7.0. Can anyone suggest me how to go for it. Thanking you.
i understand that the filegroup for a table can be specified in the CREATE Table statement. just out of curiosity, is there any way to move a table to a different filegroup, that too, if the table contains data.
Hi, There is a table which is about 50GB is size. I am thinking of placing the database of this table into a separate .ndf on a separate drive on the server. Is it possible to place this particular table into a searate drive to increase the performance even more? Basically my question is: is it possible to place tables into separate .ndf files? Thanks
Hi, I have created a database with two filegroups called FG_GroupData, FG_GroupHistory. FG_GroupData is set as default. FG_GroupData contains two secondary data files i.e. GroupData1.ndf and GroupData2.ndf I can create a table so that it is stored in FG_GroupHistory. i.e. CREATE TABLE dbo.OrdersHistory ( OrderID int NOT NULL, ProductID int NOT NULL, CustomerID int NOT NULL, UnitPrice money NOT NULL, OrderQty smallint NOT NULL ) ON FG_GroupHistory Questions: 1) How do I add tables to each .ndf file inside a group i.e. FG_GroupData For example, how do I add a table to GroupData1.ndf and one to GroupData2.ndf ? 2) I guess there is no need to place the file name i.e. .ndf inside the select query Thanks
What is the advantage of having two secondary files inside a filegroup. For example, I can create a table and place it inside a filegroup which obviously will use the secondary files. Not sure why some DBAs create just one but otherscreate more than one secondar files in a filegroup. I have read the booksonline but can not figure out the advantages. Thanks
hello friends i have table1 and 200 coulumn of table1 :) i have 647.600 records. i entered my records to table1 with for step to code lines in one day :) i select category1 category2 and category3 with select code but i have just one index.. it is productnumber and it is primarykey..So my select code lines is so slow.. it is 7-9 second.. how can i select in 0.1 second ? 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 ??? Also my search code line have a dangerous releated to attaching table1 with hackers :) cheersi send 3 value of treview1 node and childnode and child.childnode to below page.aspx :) Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Me.IsPostBack Then If Request("TextBox1") IsNot Nothing ThenTextBox1.Text = Request("TextBox1") End If If Request("TextBox2") IsNot Nothing ThenTextBox2.Text = Request("TextBox2") End If If Request("TextBox3") IsNot Nothing ThenTextBox3.Text = Request("TextBox3") End If End If Dim searchword As String If Request("TextBox3") = "" And Request("TextBox2") = "" Then searchword = "Select * from urunlistesi where kategori= '" & Request("TextBox1") & "'" End If If Request("TextBox3") = "" Then searchword = "Select * from urunlistesi where kategori= '" & Request("TextBox1") & "' and kategori1= '" & Request("TextBox2") & "'" End If If Request("TextBox3") <> "" And Request("TextBox2") <> "" And Request("TextBox1") <> "" Then searchword = "Select * from urunlistesi where kategori= '" & Request("TextBox1") & "' and kategori1= '" & Request("TextBox2") & "' and kategori2= '" & Request("TextBox3") & "'" End If SqlDataSource1.SelectCommand = searchword End Sub
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 . .
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 ??
Can anyone show me in SQL7 how to obtain Available Space on a particular filegroup in a database (not the database or datafile). I am trying to include this in a script to monitor my database which uses Filegroups and I have every other info that I need (from the sysfiles table) except the available space. Thanks in advance!
1. from Transcender ..... One file for each filegroup is sufficient because creating multiple files for the same filegroup on the same disk does not provide any performance gain
2. from bol .... Therefore, creating more files per filegroup can help increase performance because a separate thread is used to scan each file in parallel
Hi , I am restoring a VLDB from a Standby server which has just .mdf and .ldf to my production server which has .mdf and a file group with a single .ndf file, i want to restore the databse on to the Secondary file(is this possible) i checked the BOl but could not figure out of what command is to be given
Is it possible to back up one filegroup independently from the second when tables in one group have foreign key relationships with tables in the second group?
A few days ago one our database's default filegroup filled up. To solve the problem one of my colleagues created a new filegroup. This didn't solve the problem as no objects were placed on this filegroup and the initial one is still full. The idea was to expand the original filegroup over a new physical disk, not to create a new filegroup on that disk. Unfortunately, this is what happened. To solve this I want to delete the new filegroup, but when I issue the command 'alter database PvgOmcsOds remove filegroup ternary' I get the message 'Server: Msg 5042, Level 16, State 7, Line 1 The filegroup 'ternary' cannot be removed because it is not empty.' Yet there're no objects placed on this filegroup. How can I get rid of this filegroup?
I am managing 120 gb SQL7 database. The 120 GB is in a RAID5 (Hardware RAID). At begining, I think I should create a user defined filegroup besides Primary filegroup, as BOL suggested.
After I read some discussions here, It appears I cannot gain any performance by adding second filegroups. Now I want to drop the filegroup I created. The Question is How?. If I do alter database, move all files from userdefined filegroup, does this mean my userdefined filegroup has gone?
I have 2 test database identical in size and table structure, only one resides on filegroups and one resides on a single file. From everything I have heard filegroups are suppose to improve performance. I stop and start the server before each test to clean out cache. When I run the filegroup test initially the first run averages 20 seconds slower then the database sitting on the single file. However on consective runs there is a significant improvement in performance with filegroups verses single files. I have the indexes sitting on a separate filegroup and 2 additional filegroups to spread the tables across. Does any one know what would be causing the performance to degrade on the initial run of the test. (The test by the way is a stored procedure that runs a select statement against each table).
I am trying to remove one of the filegroups in the development database to shrink its size down. I started with emptying and removing its files and ran: dbcc shrinkfile (pubs_data_1,emptyfile) go
and it ran fine, with 'DBCC execution completed' message
but when I tried :
alter database pubs remove file pubs_data_1 go
I got 'pubs_data_1 cannot be removed because it is not empty'. I even tried to go to each of the tables and delete from them first which didn't work, then drop all tables in that filegroup (I knew which tables are located on that filegroup), that didn't work either.
Any ideas? Is there a way to check what else sits on that filegroup?
We have sql 2000 server at a remote site that log ships to a standby server at the site, and back here to corporate. For performance we are adding a new RAID array to the remote servers along with a new file group for indexes. The server back here is older and we can't add this RAID. For log shipping purposes, what if anything might happen to this server when the filegroup is added. We are going to be using this filegroup for indexes
