I have one complicated problem with SQL data files. Say that we have four data files:
F1=2000MB
F2=1000MB
F3=3000MB
F4=1500MB
We want to add 3000 MB on these files, and in the same time we want to make the files proportional one with each other:
Will do:
F1 + 500=2500MB
F2 + 1500=2500MB
F4 + 1000=2500MB
With my logic, the final result we’ll be:
F1=2500 MB
F2=2500 MB
F3=3000MB
F4=2500MB
There is an algorithm or a formula to calculate the right value to add to each F1, F2….Fn files having S1, S2….Sn sizes for a T total value to add? Thank you in advance.
P.S. The problem can be complicated when we deal with more than one filegroups and with disk space availability.
hi, how can i fill dropdownlist through code not through visit.and i need to know which is fastest and easy way for web application throught this below query. cmd.Connection = conn conn.Open()Dim ds As New DataSet cmd.CommandText = "SELECT Emp_Name,Emp_ID FROM Employee " da.Fill(ds, "data") cmd.ExecuteNonQuery() conn.Close()
Currently we have tables (in sql 6,5), many of them do not have primary keys. While I was trying to re-index (re-org), many of them got an error: "fillfactor 204 is not a valid percentage; fillfactor must be between 1 and 100." (many tables' fillfactor exceed 100 or more...) How can I fix them so I can upgrade to sql 7 ? Thank you for your help.
I am really confused about this whole fill factor thing. The way I understand it, is if you have a table whose data remains pretty much static, you should use a higher fill factor. Suppose you had a database where you had at most 150 transactions a day that changed the data, should the fill factor be left at the default(0) or increased? How do you determine how much to increase it? Is there a rule of thumb that suggests if you have x number of changes against a table, you should have a fill factor between y and z percent?
Hi all, While creating indexes for a table, I specified a fill factor of 70%. I then inserted a few hundred rows into the table. Is it possible to check to what percent the pages are full after the rows have been inserted?
You have a db with 50,000 records and you want to add 100,000 more. What should the right fill factor be? Is there a way to "calculate" a fill factor if you don't want to use default? Any help is appreciated. Thank you.
I have a web online table that is inserted about 1500 record one day. Each night, a DST is running to pull all data to anther database. How to set fill factor on a one column index to get the best performance? Current fill factor is 80%.
Hi experts, I would like to ask regarding FILL FACTOR. I observed that our system's loading is a bit slow, and some of the modules take 1 to 2 minutes loading. Maintenance activity is regularly executed based on the scheduled sets. Then I tried to checked the tables indexes/keys turns out that the FILL FACTOR is set to ZERO(0). I would like to know if the FILL FACTOR set to zero will be a factor for the system to slow down..????
How do you fill out an order form; there is an Order(OrderID, CustomerID, Subtotal, Tax, Total), Orderdetail(OrderID, ProductID, Qty, UnitPrice, ExtendedPrice)
How do I get those tow together in the same form, which can be called order, or invoice it doesn't matter as long as I can get them in the same form numberd like order 1, then order 2, ect. is it by stored procedure, or by ado.net, or both ? or is there anywhere I can find information? like a book? or website ?
All,SQL Server uses a proportional fill method to add data to file groups wherea file group has multiple files. In general this is a good thing.Unfortunately, the method appears to get switched off when new file(s) isadded. Other than exporting the data out of the filegroup, recreating thefilegroup and putting the data back in, is there a way to respread theexisting data back out and switching the proportional fill method back on?Thanks,Danny

Hello guys! I am relavtively new to ASP.NET programming ang was just starting out on my first project. I am using ASP.NET2.0 technology by using Visual Web Developer 2005 Express Edition and of course with SQL 2005 Express Edition. I would like to develop a database for our IP addresses, so one field of my table in a SQL data is the field for IP addresses.I would like to write a program wherein after clicking the button, that field will be automatically filled up with IP addresses (e.g, from 192.168.0.0 to 192.168.0.255).How do I accomplish this kind of dynamic filling up of fields? Thanks a lot!

You have 50,000 records in a database file and you know you want to add another 100,000 records in the next several weeks. What fill factor would you use to maximize performance? A.0(default setting) B.30 C.70 D.100 which one is correct? And how to calculate fill factor?
I am a little confused about what fill factor to use in creating a clustered index on one of our major tables. This table has about 4.5 million rows and currently there are 14 indexes associated with it, but no clustered index. I want to create a clustered index (on datestamp )on this table, but cannot really grasp what fillfactor I should use. The main use of this table is in daterange reporting. No deletes are applied to this table(except archiving on an annual basis). It grows by about 5 000 rows daily. From what I have read in BOL, a high fillfactor(100) is only applicable for a read only table, and I feel that at the time of creating a clustered index on this table, it is readonly, cos the data will never need to be reorganised to insert a new row into it, only at end. BOL states that a low fillfactor could degrade database read performance, and where the vast majority of our processing(reporting) hits this table,that is a major concern. BUT BOL also says that a low Fillfactor is recommended where there are changes to the data. Space is obviously important, but access speed is overwhelmingly more important. Should I use a fillfactor of 70/80/90 etc. Any help would be appreciated
I have some non-clustered , non-unique indexes on a medium sized table (25,000 rows). The fill factore is showing 248% on these indexes. I have tried setting the fill factor to various values 100% or less. The re build index seems to work, however the est min/avg/max size of the index all show appx 160Kb, whilst the actual size is in excess of 50Mb !!
We run a weekly rebuild of all indexes overnight, without any fill params and following this the fill on these indexes goes back to 248% !
I have also dropped and re-created the index with a fill of 100%, and it has still reverted to 248% following the weekly rebuild.
I have also looked at the server config, and the fill factor there shows a running value of 171% !!, although the current config is set to 0.
The server is stopped every evening, so no way should the config have a value of 171, especially since the max allowed value is 100.
Any advice/assistance would be gratefully received.
I know what fill factor is ... and know that I should set it high when I have static data tables (where the data rarely changes) and low when I expect to have page splits ...
but does anyone know what affect on performance this setting has ? I don't quite get what Books Online says about it.
Can u plz tell me what is fill factor and what its role in defining the indexes. It is by default 0% and can be set upto 100%, but what it makes difference if i change the percentage? Where it is exactly impacts? If u know any links then plz forward me.
I am trying to set up the relationship (Primary Key and Forign Key) in several tables. I would like to find a way also be able to set 'Fill Factor = 90%' in the script. Here is the code that i have so far:
I am working with some data that is not so clean. I have some rows that are Very close to being a duplicate row. I need to take all the rows with the same SKU number and fill in the missing data for the Price, Cost or the SalePrice, what ever may be missing. The data is set like @Diamonds MissingData and I need the row to look like @DiamondsWithData table. I can remove the duplicate values once I get the missing data filled in.
I have a database with a couple of tables i need to expand to 4 gigabytes in order to run some tests. (currently 300 megs) Does anyone have a script or some method that would quickly populate my tables with random data so that i can grow my database to the desired size for testing.
Thanks
I have SQL server 2005 express. I have the management studio installed too.
Is there any such thing that you can find the current Fill Factor for each indexing? The only thing that you have an indication is by looking at DBCC SHOWCONTIF > Scan Density [Best Count:Actual Count].......: 100.00% [0:0] and if this value is not reaching 100% means may have an issue with fill factor ?!!?
HiThere are a lot of articles about the fillfactor.I did change the fill factor and that did not work as intended.How do I get back to the default fill factorI am using sp_msforeachtable undocumented database procedureand when the indexes are rebuilt the fill factor that shows upin origfillfactor is the one I am trying to move away fromYour help will be appreciatedVince
