Size Of Tables
Nov 16, 2001
I'm having to do some estimation on the size of the db that I will eventually create.
I have a 6.7 million row table that holds 5 integers and a varchar(8).
Therefore my crude maths are that an integer is 4 bytes and a varchar is max 8 and therefore each line is 28 maxmimum bytes long. Multiply by 6.7 million and you get 1876000000 bytes or 183203KB or 179MB's.
With me playing with this table the db has balooned from 23mb to 1,325mb. This doesnt work out. One possible explanation is if SQL Server does the same as Access and you need to compress to gain the space back. I wasn't aware of this though. I have filled and emptied the table several times over to test the import routine.
I therefore have a few questions.
1. Why has the db ballooned to this size?
2. How do I accurately work out future db/table sizes?
3. Is there a way to work out the size of a table?
4. Do SQL db's have to be compacted like Access's?
Help appreciated.

I am finding that the size of my SQL Server 7 tables are approx 75% LARGER than the same Visual FoxPro table. I am not considering indexes in either one. The only difference is that the SQL Server table has a timestamp that the Visual FoxPro table does not.
Is this normal? or did I do something wacko?
I upsized the data from Visual Fox to SQL by appending the info in the Visual Fox table into a remote view and then doing a TABLEUPDATE to send it to SQL Server.
Any help would be appreciated.

Hi,
I know I can check individual table's properties for the size and row count of each, but is there a way of doing it for all tables within a database in SQL server 2005 ? I have about 69 tables in one..
Thanks,
Raddy

Hi,
I have a database which is 25 GB in size. The database has few tables.
Can I individually find out which table is occupying more space?
Thanks

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?

Is it possible to determine the data size of records in a table. basically I would like to run a select query with a condition and the result will be xKB. I know that this is possible on a database level, but can it be done on a record level (or number of records).
Cheers

Does anybody know how to make a query that presents ALL
tables and their sizes (in Kb or Mb) from a database?
Is there a Stored Procedure for this purpose?

The following procedure will display the size of all the user tables in a database.
CREATE proc sp_tablesize
as
if exists (select * from sysobjects where name = 'sp_tablesize')
begin
goto calculate_tablesize
end
else
begin
CREATE TABLE #SpaceUsed
(
TableName sysname,
TableRows int,
TableSize varchar(10),
DataSpaceUsed varchar(10),
IndexSpaceUsed varchar(10),
UnusedSpace varchar(10)
)
goto calculate_tablesize
end
calculate_tablesize:
declare @tablename nvarchar(50)
declare @cmd nvarchar(50)
declare c1 cursor for select name from sysobjects where xtype='u'
open c1
fetch c1 into @tablename
while @@fetch_status = 0
begin
set @cmd='exec sp_spaceused['+@tablename+']'
insert into #SpaceUsed exec sp_executesql @cmd
fetch next from c1 into @tablename
end
select * from #SpaceUsed
drop table #SpaceUsed
deallocate c1

How do I get a list of table names and their sizes, sorted by sizes? The command sp_spaceused only lists one table at a time.
Thanks for your help.

I have 57 tables, 7 views and 1 stored procedure. Just wanted know based on these requirements how can I find the size of the database. Though the DB contains lots of tables, views and procedures. I am moving these details to new DB server. So I need to put right requirements.

I have a Db that is 1.7 gigs. The table data takes approximately 200megs. The transaction logs were truncated. Where else can this large size be coming from and how can I confirm?
DB is generally small. ~25 tables, 100 SPs, 10 views, etc.
Note:
I have 4 queues using SQL Notifications, but when selecting from them results in no data.
Thanks

I have used the following script to add the size of chosen tables in all the databases on a given server. What I need to do is to create a GRAND total. Can someone give me a hint?
exec sp_msforeachdb
@Command1 = "print'?'",
@Command2 = "use ?
SELECT CAST (o.name as char(20)) as 'Table', SUM(c.length) 'Record size',
MAX (i.rows) '#of rows',
CONVERT (decimal (10, 4), SUM (c.length * i.rows)/(1024.00 * 1024.00)) 'Approx. size (MB)'
FROM sysobjects o, syscolumns c, sysindexes i
WHERE o.id = c.id
AND o.id = i.id
AND (i.indid = 1 or i.indid = 0)
AND o.type = 'U'
And o.name in ('Table1','Table2','Table3')
GROUP BY o.name
COMPUTE SUM (CONVERT (decimal (10,4), SUM (c.length * i.rows)/(1024.00 * 1024.00)))"
Thank you

For finding size values of temp database:
select * from sys.master_files -
size column value here is 1024 for .mdf,size here for .ldf is 64
select * from tempdb.sys.database_files -
size column value here is 3576 for .mdf,size here for .ldf is 224
Why is there a difference and not the same. size columns in the above 2 tables for temp db's do they represent different values ?

I have seen a bunch of ways to get the size of all the tables within a database posted on this board. I decided to modify an older one I found here (http://www.sqlteam.com/item.asp?ItemID=282). I set it up so there is no cursors or temp tables. Pretty much just one select statement to return all the info you would need. It seems to be faster than anything I have seen so far. Take it for whats its worth. Thanks to the original creator.

Hello All,
When creating my database I have modeled some of the tables after the Adventureworks sample database.
There are some fields or entire tables in Adventureworks that I do not see an imediate use for, however; I would hate to ommit them to find out later they would have been benificial. (.eg territory table).
In general terms what would the impact be on size and performance of a database which contains tables or fields that do not contain data.
Thanks for your help!

I have a database consisting of two main tables and 12 sub tables.
This was leading to increase in database size. So we thought of storing the sub tables data in the main tables in form of xml  in a column of varchar(2000) type.
So we created a new database that only had 2 tables and we stored the data of the sub tables in the new column of the main table.
Surprisingly we saw that the database size increased rather than decreasing .

I am in the process of designing a SQL 2005 database with tables that may hold several hundreds of millions of rows.
Due to various constraints, I am trying to save as much space as possible by optimizing the size of a row. Currently one row contains the following columns:
byte(4), byte(3), byte(3) = 10 bytes.
Adding 4 bytes for the row header, plus 3 bytes for the null bitmap (as described in BOL) I am ending up with 17 bytes/row. In a real world test it was an average of 18.3 bytes/row.
There are no indexes, no primary key and all columns are not NULL. Hence my question: since no column allows a null value, is there a possibility to "remove" the 3 bytes Null Bitmap?
Is there any other way to shave off one or two more bytes by using a clustered index etc?
Thanks

I found it pretty interesting. I checked the size of a database, before implementing database compression across all the user tables in a database. And Post implementation of compression too I checked the size of the database.
I did not find any difference. But if I expand the table and check propetires->storage and I can see that PAGE compression is implemented across all the tables, but no compaction in the size of the db. It still remains the same.

In SQL Server 2014, how big for the block size is better for performance? 64 KB? 4 KB?
For normal database files, best practise is 64 KB disk block size. Not sure if it is same for memory-optimized filegroup.

I have a report where in I have a combination of matrix ,table data regions.
The problem what I am facing is that the data tables don't remain fixed in their position and they tend to move down.
E.g. table 1 and table 2Â are on the same page in design time side by side (right and left)however during the runtime the table1 is pushed down and table2 is at its position .
Now how can I keep them all fixed in their same position. Most of the tables have fixed size rows and some who have high size of rows have been put at the end . What settings we can set?

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
