The tables in my database somehow are getting set with a fill factor of 90. In the properties of the server/Database Setting, the "Fixed" option is unchecked. Last Friday, I reset the each table to have a fill factor of zero, but when I came in today, the tables reset themselves to having a fill factor = 90. Any ideas of why this is happening and how I can stop this? Your help is greatly appreciated.

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?
Please Help

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?
Thanks in advance,

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%.
Thanks

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 i find out how much fill facot has been spcified in given table?.

Any input is appreciated.
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 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.
Thanks

Hi ,
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.
Thanks And Regards,

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:
ALTER TABLE Req
ADD CONSTRAINT FK_Req_Bow FOREIGN KEY ( BowID )
REFERENCES Bow ( BowID )
Any help would be greatly appreciated!

Hi there
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 ?!!?
Also, how about SQL2000?
Thanks
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

I have a clustered index that starts with an INT IDENTITY(1,1) column and therefore you can only add data to the end of the cluster. What I'm confused about is the relationship between this and the fill factor. In a normal fill factor scenario you'd be worried about inserts causing page splits but if you can only append to this cluster does this mean I should set the factor to 100% even if I'm expecting a large number of inserts? Basically I don't understand what happens when you run out of space on a page on a B-tree if it's based upon an ever increasing number.
If I have a clustered index on only one column of the table, the column being the primary key and an identity column ( int datatype, Ascending CIDX), then can I go ahead and have the Fill Factor be 100%. I may add more rows at a later date to the table.
Let me know.
Hi,
Now i am doing a R&D on indexes in SQL 2005. I want to know clearly what is the actual uses of Fill Factor? What is advantage and disadvantage of it?
Where it should use this fill factor?
Please answer me as soon as possible.

I am about to rebuild all my indexes on a database that is very heavily fragmented. In looking at the report, seems that 80% or more tables are 90%+ fragmented.
My understanding is that fill value value is used for performance reasons. Our shiny new backend SAN is 100% SSD. If solid state can provide a sub-millisecond response, is fill factor still necessary at the cost of additional space being used used?
Are there any rules of thumb to apply when entering the Index Fill Factor?
I just want to make sure I'm enter a optimal value.
Using MS SQL 2000.
Thanks!

As the title says I re-indexed all of my databases using the wrong fill factor. Instead of using 90% as the fill factor I misunderstood and set this at 10%. So I believe my databases are now packed with a ton of unused space. The DB sizes should be about 5-6 GB but have since grown to 20-40GB. I am very new to SQL administration and don't know of a safe way to remove this unused space so that my databases return to their normal sizes. The databases do not grow very much at all so the free space is not really that necessary.
View 9 Replies View RelatedIs the "Fill Factor" percentage is same as the "change free space per page percentage to" option in the Rebuild Index task wizard?
OR Is it inverse of it ?
Any comments and suggestions are welcome.....

Hello everyone,I face currently a problem where I could need some input for searchingthe source of the ProblemSystem: SQL Server 9.0I fill from Database A with triggers Database B, everything worksfine.On Database B there is a Stored Procedures that checks the records andadd additional information accordingly, this Stored Procedures isnormally called by the application on "update and insert" in theaccording table.When I try to call this Stored Procedures from the Database A, thetrigger does not work anymore, even if I do a try catch over the wholetrigger, he never reach the Catch and the insert I try to do there toget the error message.On both Databases the user, that is taken to execute the trigger isexistent and DB-Owner of both Databases.If I go and execute the Stored Procedures manually after an insert orupdate to Database B everything works fine.I also already tried to check on Database B if there is an insert orupdate from Database A and if, to execute the Stored Procedures, withthe same result, nothing and all happens anymore, neither update onDatabase A and also not on Database B.And also I cant catch the error as the Try/Catch is not working.Hope I could explain it understandable and maybe someone remembersalready having the same problem.Thanks & Best regardsPascal

Hi,
I have a report which uses a parameter called "Interval" with possible string values of "Daily", "Weekly", and "Monthly" and I want these values to set the default values for my StartDate and EndDate parameters. However, the default value remains static. And I have tried all of the solutions found in this forum. Any suggestions?
I am using SSRS 2005. And I have tried using an iif statement for StartDate, also tried Property->Custom Code, and also tried using stored procedure to populate Start and End Dates, but none of these provide dynamic parameter setting like I was hoping for.
And I think this should work because I know that if it is not a date that it works correctly. For example if I have one parameter called country and a subsequent one named state, every time I change the country it will let me re-pick the state. But this is not working correctly here.
Any ideas on what I am doing wrong or how to fix this?
Hello,
I have a report parameter StartDate. Properties are
DataTypeataTime
Prompt: StartDate
Default Values:
Non Queried : =NOW()
I set the default value to Now(). When I go to preview, the StartDate parameter is blank and its been locked & grayed out. I also tried
Today() and Globals!SystemTime but that does not work either. Is there any other solution to make this work?
Thanks

While creating a table, can we default a column to be UPPER. So that even if we insert a lower case, it should be converted to UPPER case.
View 4 Replies View RelatedI have two parameters in my report (StartDate and EndDate). I want to default these parameters to the previous month.
For example... If today is 5/17/2007, I want StartDate to be 4/1/2007 and EndDate to be 4/30/2007. If today would be January 30th 2007, I would want StartDate to be 12/1/2006 and EndDate to be 12/31/2006.
