I have a table in which there is a column called 'Forecast' of type 'int', that is null for about 25% of the rows in this table.
Will null value for this column consume storage bytes?
In OO programming, data references, such as pointers in C++ or objects in C#. If the reference is null, it points to no object, or to 0x000000, thus the "referenced" object is non existent and the "object" takes up no RAM.
I know pointers are not the same as Database values, but what I'm interested in knowing is, on the bits and bytes level, what is a "NULL" and how much space does it take up, as much as is the field? Or just one byte? and when a NULL is replaced does that cause a shifting in the data of the database page or does the new data simply replace the null?

Hello
I need to setup a compaq sever with 300 MB database, and will be adding around 600 records on a daily basis. Can someone help with how much disk space i should have on sqlserver, providing i have c: and d: setup.
Thank you in advance for all the help.

Hi All,
I have a server and it has C: D: F: I: Drives and all the system files are on C:Drive and and all the .MDF's and .LDF's(model,temp,master) are on the F: Drive and now I am running out of space on both(C: and F: Drives)
1. Can we add space to the C: and F: drives on the fly?.
2. Can I move the System databases ( MDF's and LDF's to some other drive)and if so, how do I do it?( Moving the databases ) and this is on the production database so when I have to do this.Will there be any impact.
Thanks in Advance,

Does anyone know how to get the free disk space for all drives in many different SQL servers.
I need to populate a report (right now output in Excel) with the free disk space of all drives on all of my SQL servers.
I found xp_fixeddrives but that is specific for the server where it is executed.
Any help or pointers to a script in the archives is much appreciated.
Thanks.
I noticed something strange today. I was running a query using query analyzer on a large database (8.8 million records) and the disk space on the c: drive was dropping and eventually went to 0. Availalbe space on the c: drive is 10GB. The query did complete. SQL server and all the databases are on the d: drive. After closing the query results in query analyzer the disk space returned. Is this a concern and is there a way to change it to use the d: for whatever it is doing?
View 3 Replies View RelatedThis is my first attempt using SQL 2000 and DTS. I am importing an Access database using the DTS wizard. The process fails with a "Not enough space on temporary disk" error. There is definitely enough space on the physical disk. I don't have any limits on any folder sizes either. What "disk" is the error talking about, and how do I give it enough space. The database is relatively small, about 10MB. I believe the database was created using Access 97. Please help.
View 1 Replies View RelatedI need a way to get the used space for a physical drive, or even the total capacity for a drive to do some calculations.
I don't want to have to write my own native code either.
Is there a stored procedure that will give this to me?
I saw the xp_fixeddrives that will give the free space, but I need one of the other as well.
Any way to get this?
Thanks,

We recently moved from v6.5 to v7.0. Now I have the databases and logs set to "autogrow". How can I monitor the disk space to ensure I do not run out of room (or is that preset as to how large it can grow ?). Can't find anything in the books online. Do I do this through the NT admin tool or through the SQL*Server Enterprise Manager and more importantly - how ???
Thanks so much for any help...

I'm trying to save a dts package and it keeps coming back with insufficient disk space. I noiticed that db MSDB was full so I manually increased the size. It was set to manually grow at 1 mb increments. But for some reason it didn't look like it was doing that so I manually increased it. Right now this is about 355 MB free so that should be plenty to save a package. But its still coming back with the same error insufficient disk space to complete operation. Any ideas on why or why it didn't grow on its own? Please help I can't seem to save any packages.
View 1 Replies View RelatedOur database -SQL Server 7.0 sp1 (NT 4.0 sp5)- is growing at a very fast rate despite the fact that we are deleting old record. It doesn't seem to be recovering disk space for the deleted records. Please let me know if there is a specific setting that can help us recover disk space. )

I'm new to these forums (and to SQL Server), so please be gentle with me.
I am developing a process to obtain information on all our remote servers/databases, and store it in a single local database.
I'm after things like db size, last backup date, free drive space etc...the usual weekly statistics.
I've linked the remote servers to my local one, and have written a few simple procedures (which exist on the local server) to grab backup and file size information from the remote tables. The output is stored locally in tables which we can then query as necessary.
I am having difficulty obtaining the free drive space details.
I'm using :-
'exec <remote_server>.master.dbo.xp_fixeddrives' to get the info, but I cannot store the output in a table on the local server. (remote_server_name, date, drive_letter, space_mb)
I wish to avoid creating any objects on the remote servers if at all possible.
I really want to pass the remote server name into the procedure, and the output to be inserted into the table.
Many thanks
is there a tsql command that returns the amount of disk space available. I want to set up a job to run and email if it gets to a certain level.

I have 600 instances on my network .... I need to monitor the Disk Space ... how should I do that I mean the best way for this would be ???
By Disk Space I mean the SQL Instance should atleat have 10% of free disk space ... If it is less , maybe an alert can be sent or something of that sort .
Now it would be a pain configuring alerts on each machine.
Is there some good way to this
Thanks in advance.
All,
I think i know the answer to this one already, but would like to check before going back to my management.
Background. In the past 2 weeks, a number of our databases have shot up in size, and are now at 100% utilisation of allocated disk space. My management have asked me to look into what is causing these to fill up so quickly.
Unfortunatly there were no snap shots or information relating to the databases / tables so i can not determine which tables have grown and are causing the problems.
I have also looked through the sql logs and the event viewer logs to see if there is anything out of the ordinary, but again apart from log / database backups there is nothing of note in there.
I am going to be implementing a solution that I got off another thread which will give me some database / table history to help me in the future, but for now is there anything else i can do? or is it a case of me getting back to the application guys and getting them to reduce data (as there is no more disk space to give them).
Any thoughts or advice you can give me would be greatfully received.

Okay, so i have a Dual Xeon SQL2k5 Server set up. it's got 4 10k RPM Raptor Drivers (160gb) on it all stripped together. my question is this, i was just doing all kinds of index tuning, and my server didnt have enough disk space to create 2two of the recommended adjustments. i'm curious, if i should just have those two indexes stored on the 1TB Backup array i have? (two 500gb 7200RPM drives)
or should i backup the database, and expand the Raptor Array and then restore the database and create the indexes?
i'm not really worried about down time as long as it doesnt exceed 2 days.
All,
I first ran indexdefrag on a table with 1.5 billion rows.
logical fragmentation was at 95%.
logical frag went down to 3% with no real effect on disk.
DBCC reindex had previously been bombing undetected.
Now I've run a reindex on this table:
Reindex Job with Fillfactor =100
Ran in 3:05
Free Disk went from ~150GB before operation to 49GB
File4 went from 347GB to 504GB
Why has so much free disk been consumed by this operation and not released ??????????
Is my only choice to shrink data file???
thanks

I need to find out how much space is available on a disk (ex. C on the server from within a stored proc on ss2000. Is there an easy way?
Thanks!
I heard somewhere that using reporting services you are able to report on more useful aspects also such as server disk space, how is this possible, or where can i find any tutorials to help me out
thanks in advance

Another question...
I need to check the space available on a specific disk (D on a remote server, again, this task will be executed from an SSIS package, if I have less than 60GB available, I have to delete some files.
How would you guys do this using VB.NET? If I had SQL Server installed on that box, I could achieve this executing a DOS command... But I don't...
Thanks!
Hello ,
I wanted to know on what basis the disk space allocation for the databases is planned . Suppose if we plan 60 GB for data files ( mdf )for a given database then what should be the space allocation for the log files ( ldf ) and the tempdb ( both mdf and ldf files ).
Is there any thumb rule or any defined ratio for the same ?
Thanks
Hello
I am trying to upgrade our 6.5 server (which approx takes up 18GIG of data/log) to 7.0...it failed since I only have 7GIG space left.
Do I realy need to come up with an additional 18GIG to accomodate the upgrade?
Thanks. Bob
We are experiencing an intermittent locking or hanging problem on our SQL Server (at the application level on the clients) and it has gotten worse very recently.
I haven't seen any processes that appear to be locked yet but I noticed that we don't have a lot of space available (the database is 1.4 gigs and we have about 245 megs available).
If this is inadequate disk space, could that be causing an apparent locking problem?
Thanks in advance for any help.
Hi All,
One of the drives that stores the database file is close to running out of space. The chance of me getting more space added to this drive any time soon are really low. What are other options I have?
Thanks.
We've got an internal database that replicates with another database server for our website.
Not all tables are replicated, some use merge and the others are snapshot based and published regularly to the public website facing server.
However, there's a lot of data (well, large textual data) that's being transferred and it seems to be generating massive log files that continue to grow and grow.
I'm fairly new to adminning an SQL Server box, so was wondering if anyone can tell me what the best way to keep it under control is? I've heard its possible to truncate the logs, effectively deleting any data that has already been processed by subscribing servers etc.?
As I said, I'm very much new to this and would really appreciate some guidance, if only to the right part of the SQL Server Books Online :)
Thanks,
Paul
Hi,

HI All
how to calculate the disk storage space of the database from the front using asp.net
Can anyone give suggestion
Thanks
I've written a SP which does some complex calculations and in the enddumps data into 2 tables (master & detail) When I run this sp forsmaller no of IDS (employees i.e for 13000 in Master and 60000 recordsin detail table) it takes around 3-4 hrs and if I run for allemployees in the database (i.e. abt 60000 records in master and 180000records in detail table) then it takes around 10hrs to complete.I'm using temp table to hold data and then do the calculations, butsometimes when I run the SP temp db starts growing and reaches up to25 GB and the process fails as there is no space left on the disk, andlately I'm not able to run the SP for every employee, I had to end theprocess after 16 hrsIf anybody can guide me what could be posible resons or where I shouldlook for solution.My row size in master table is arounnd 2000 bytes and in detail tableabt 300 bytes.Thanks in advance.Subodh

Heads up on TEMP files
I've been running web Synchronisation for over a month. Just today some subscribers received a message warning of an "OS Error" could not retrieve file "dynsnapshotvalidation.tok". Sometimes they also got an error regarding low or no virtual memory. After much investigation it seems that the Web Server hosting the web sync IIS had literally no space left on the system c: drive. It also turns out that the \WindowsTEMP folder contained over 9GB of snapshot files.
It seems that when the Web server collects snapshot files from Data Server to deliver to the subscriber it creates a Temp copy on it's own local system. Unfortunately this temp data is not cleaned up and over time has jammed up the system and caused this failure.
Is there an answer to this or does it involve manually checking the server from time to time to clean-up the TEMP folder?
Has anyone else noticed this?
Thanks
Rab
