SQL Server Row Size
Jul 29, 2007
I am using SQL Server 2000.
One table I have created consists of several char or varchar columns. The total (max) row size I computed is 7,999 bytes, by using the following code:
Select sum(c.Length) from Syscolumns c Inner Join Sysobjects o on c.id=o.id
WHERE o.Name = 'mytable'
However, SQL Server reports the length of the table to be 8,070 bytes and warns me that it exceeds the max size of 8,060.
Why are the row sizes different when I compute it vs SQL Server?
Thanks in advance.

I am trying to resize a database initial log file from 500M to 2M. I€™m using€?
ALTER DATABASE <DBNAME> MODIFY FILE ( NAME = <DBLOGFILENAME, SIZE = 2 ) "
And I'm getting "MODIFY FILE failed. Specified size is less than current size." I tried going into the database properties and setting the log file to 2M, but it doesn€™t keep the changes.
Any help with this process?

I installed sql 2005 a while back. Then I recently found out my file system was fat32 (I don't understand why the hardware people did this...) and I had to convert to NTFS. Naturally the sql service no longer worked so I uninstalled inorder to reinstall now I can't reinstall it I keep getting this message
native_error=5039, msg=[Microsoft][SQL Native Client][SQL Server]MODIFY FILE failed. Specified size is less than current size.
I'll try to post the full log in a new post.

Hi folks,Can anyone enlighten me here? I'm trying to use a SPROC which, when supplied with an int, looks up the table and returns certain columns from it. I'm using a SqlCommand, here's my codebehind: ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ SqlCommand dataSource = new SqlCommand("retrieveData", new SqlConnection(dbConnString)); dataSource .CommandType = CommandType.StoredProcedure; dataSource .Parameters.AddWithValue("id", poid); dataSource .Parameters.AddWithValue("title", title).Direction = ParameterDirection.Output; dataSource .Parameters.AddWithValue("creator", creator).Direction = ParameterDirection.Output; dataSource .Parameters.AddWithValue("assignee", assignee).Direction = ParameterDirection.Output; etc, etc... And the SPROC:------------------------------------------------------------------------------------------------------------------set ANSI_NULLS ONset QUOTED_IDENTIFIER ONGOALTER PROCEDURE [dbo].[retrieveData] @id int, @title varchar(50) OUTPUT, @creator varchar(50) OUTPUT, @assignee varchar(50) OUTPUT, @contact varchar(50) OUTPUT, @deliveryCost numeric(18,2) OUTPUT, @totalCost numeric(18,2) OUTPUT, @status tinyint OUTPUT, @project smallint OUTPUT, @supplier smallint OUTPUT, @creationDateTime datetime OUTPUT, @amendedDateTime datetime OUTPUT, @locked bit OUTPUT AS /**SET NOCOUNT ON; **/ SELECT [title] AS [@title], [datetime] AS [@creationDateTime], [creator] AS [@creator], [assignee] as [@assignee], [supplier] as [@supplier], [contact] AS [@contact], [delivery_cost] AS [@deliveryCost], [total_cost] AS [@totalCost], [amended_timestamp] AS [@amendedDateTime], [locked] AS [@locked] FROM purchase_orders WHERE [id] = @id; ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ The id being passed in is definately not null, and is set to a value of an item I know exists. The resulting error is:
Exception Details: System.InvalidOperationException: String[1]: the Size property has an invalid size of 0.Line 63: retrievePODetails.Connection.Open();Line 64: retrievePODetails.ExecuteNonQuery();[InvalidOperationException: String[1]: the Size property has an invalid size of 0.] System.Data.SqlClient.SqlParameter.Validate(Int32 index) +717091... ... Can anyone see anything I'm missing? Thanks,Ally

Using C#, SQL Server 2005, ASP.NET 2, in a web app, I've tried removing the size from parameters of type NCHAR, NVARCHAR, and VARCHAR. I'd rather just send a string and let the size of the parameter in the SP truncate any extra chars if need be. I began getting the error below, and eventually realized it happened only with output parameters, as in the code snippet below.String[3]: the Size property has an invalid size of 0. par = new SqlParameter("@BusinessEntity", SqlDbType.NVarChar); par.Direction = ParameterDirection.Output; cmd.Parameters.Add(par); cmd.ExecuteNonQuery();What's the logic behind this? Is there any way around it other than either finding out what the size should be, or assigning a size larger than would ever be needed? ThanksMike Thomas

I want to know encrypted data's size for designing database field size.
For example, cardnumber varchar(20) Encrypted by Triple_DES and PassPhrase, How match size does need to encrypted data store field.
I think the size does not depend to PassPhrase char length.

Just wanted to know what is a general rule of thumb when determining log file space against a database's data file.We allow our data file for our database to grow 10%, unlimited. We do not allow our log file to autogrow due to a specific and poorly written process (which we are in a three month process of remove) that can balloon the log file size.Should it be 10% of the Data file, i.e. if the Date file size is 800MB the log file should be 8MB?I realize there are a myraid of factors that go against file size but a general starting point would be nice.ThanksJeff--Message posted via http://www.sqlmonster.com

Hi,
An MSSQL DB running SAP indicates a smaller DB size (MMC & SAP) than the actual physical size. The difference is about 8 GB.
A lot of records were deleted before this. Did they remain in the DB as NULL values or something ?
Does anyone know what the reason for this could be ? And how to clean this up ?
Thanks in advance,
Paul

Hi,
i use this script that show me the size of each table and do the sum of all the table size.
SELECT
X.[name],
REPLACE(CONVERT(varchar, CONVERT(money, X.[rows]), 1), '.00', '') AS [rows],
REPLACE(CONVERT(varchar, CONVERT(money, X.[reserved]), 1), '.00', '') AS [reserved],
REPLACE(CONVERT(varchar, CONVERT(money, X.[data]), 1), '.00', '') AS [data],
REPLACE(CONVERT(varchar, CONVERT(money, X.[index_size]), 1), '.00', '') AS [index_size],
REPLACE(CONVERT(varchar, CONVERT(money, X.[unused]), 1), '.00', '') AS [unused]
FROM
(SELECT
CAST(object_name(id) AS varchar(50)) AS [name],
SUM(CASE WHEN indid < 2 THEN CONVERT(bigint, [rows]) END) AS [rows],
SUM(CONVERT(bigint, reserved)) * 8 AS reserved,
SUM(CONVERT(bigint, dpages)) * 8 AS data,
SUM(CONVERT(bigint, used) - CONVERT(bigint, dpages)) * 8 AS index_size,
SUM(CONVERT(bigint, reserved) - CONVERT(bigint, used)) * 8 AS unused
FROM sysindexes WITH (NOLOCK)
WHERE sysindexes.indid IN (0, 1, 255)
AND sysindexes.id > 100
AND object_name(sysindexes.id) <> 'dtproperties'
GROUP BY sysindexes.id WITH ROLLUP) AS X
ORDER BY X.[name]
the problem is that the sum of all tables is not the same size when i make a full database backup.
example of this is when i run this query against my database i see a sum of 111,899 KB that they are 111MB,but when
i do full backup to that database the size of this full backup is 1.5GB,why is that and where this size come from?

I have a site which provides online studying for students in a graduate program. Apparently their final was today because lastnight everybody was on. I know, however, that this is a small class, so no more than about 80 people could be on the site at one time. I still got SQL errors (emailed to me from Application_Error). I read on MSDN that by default connection pooling should be in place, with a pool size of 100... that would mean I wouldn't have this problem if only 80 students were on the site.
Why is this happening?
Below is my connection string from web.config.
<add key="connStr" value="Server=xxxxxx;Database=xxxx;UID=xxx;PWD=xxx;"></add>Error:
System.InvalidOperationException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.

Good evening,
I have a SQL Server 2005 database installed, serving as back-end DB, for an ASP.Net 2 application. Currently the database size is nearly 800Mb with recovery mode set to Simple. Every single day a maintenance job runs shrinking the db size, reorganizing indexes and statistics, etc.
Since I'm not an expert in SQL Server Administration I'm trying to figure out if this space is really necessary. The previous version of this application was running under PHP5 and MySql 4. After a year, with pretty much the same load as the current version, the database size was arround 370Mb. With the SQL Server it's already -800Mb after 3 months.
Pretty much my guess is that I'm doing something wrong. I just don't have any idea of what might be going on. If one of you guys could throw in some ideas on how to check if this size was really necessary and, if not, how to reduce it, I'd be very thankful.
Best regards,
ahkaru

When using connection string connect to sql server, there is a item max pool size.
The default is 100.
I set it to 500, but still get max pool size is reached and timeout error.
I checked my code and do open and close each connection each time using connection, so should have no memory leak.
What is the maximun value for max pool size? how to calc this size based on the memory used by SQL Server?

Here are my scenarios:
We have an application with replicated environment setup on sql server 2012 . Users will have a replica on their machines and they will replicate to the master database. It has 3 subscriptions subscribed to the publications on the master db.
1) We set up a replica(which uses sql server 2012) on a machine with no sql server on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 33gigs and ldf has grown to 41 gigs. I went to sql server management studion . Right click and checked the properties of the local database. over all size is around 84 gb with little empty free space available.
2) We set up a replica(which uses sql server 2012) on a machine with sql server 2008 on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
3) We set up a replica(which uses sql server 2012) on a machine with sql server 2012 on it. We have dropped the local database and recreated the local db and did the initial synchronization using replmerge tool. The mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
Why it is allocating the space differently? This is effecting our initial replica set up times.

hi,
im doing network monitoring app where basically i run a checks on servers every few minutes and log the data to a table. Naturally the table can get big, quite quickly. What I want is to be able to overwrite the table data at the start of each new day. Alternatively, rollup the data into a daily or weekly packets and then overwrite table data. How do i do this?

Hi!,
I have a process(Peoplesoft) in SQL Server which takes long time to finish. I am looking for is there any way to find out fragmentation of the table to defagment it or is there any way to allocate the size for particular table. Couple of users are running the process at same time but as SQL Server has table/page locks it locks and releases after the job is done. Can i make it row level lock by executing sp_tableoption procedure. I would appreciate for all your suggeations.
Thanks,
Mohana

Am running several databases on SQL server 2000.
Have several overnight jobs for interface and maintenance, etc.
Log file on one specific database increases in size 10 fold overnight. Unable to trace why.
I have a job to truncate the logs before the final overnight backup. Several times a week the job hangs - on nights when log file expands, so it is a pain. Able to resolve the issue after the event, but do not understand why the log file increases in size (at that time) in the first place. No other activity on the server at the time.

Hi,We are in the process of selecting a database for a data warehouse typeapplication. I want to get a feel for how big can a SQL Server databaseget. As per Microsoft, it can be multiple terabytes. Can you tell meWhat is the biggest size SQL server database you manage? (I understandbig is a relative term. I consider 500+ Gig as big).Do you see any major performance problems due to size of the database?(Given that the database is designed optimally).Really appreciate your help.Thanks,Joseph

Hi,
I am currently using the SQL Server Express edition with the intention of upgrading to the full version in the future.
I know the size limitation on the Database is 4GB - however does this include the log file as well? Nothing I read says the log file is included however if anyone can give the definitive answer I would be grateful.
Also my log file maximum is set to 2GB what issues are there with reducing this to say 500MB? I assume SQL Server automatically drops the old log data to add new data when the maximum is reached.
Thanks for your help.

I've created a database design and I'm trying to figure out if it's workable or not. I have 2 tables in particular that are sparse (20 columns, but only a few have data - about 100 bytes/row) but will grow very large - to the tune of 700 million rows.
My question is whether or not there is a problem with SQL Server 2005 having 1.5+ billion rows of data even though it will likely only take up 100 gigs or so on disk. Anyone have experience in large numbers of rows like this? We're still doing testing as far determining how slow queries will get.
Thanks,
Craig
