How To Calculate The Space (size In Bytes) Used By A BLOB Column In A Row
Dec 3, 2007What is the easiest way to calculate the space (size in bytes) used by a BLOB column that is already stored in a particular row?
Thanks.
What is the easiest way to calculate the space (size in bytes) used by a BLOB column that is already stored in a particular row?
Thanks.
We are close to exceeding the Maximum Row size of 8K per row and the CIO asked me "how close are we to reaching the 8K row limit?"
I began by looking at byte requirements for the data types we are using
from the systypes table then I wondered, do the indecie, Foreign Keys and Primary Keys use bytes which must be included in my Calculation for current number of bytes used per Row.
Question: How do I calculate Current total number of bytes used per row.
Sql Server has many data types.
For Example:
smallint
Integer data from -2^15 (-32,768) through 2^15 - 1 (32,767). Storage size is 2 bytes.
I want to know that
If it contains like 0 or 100 or 1000 or -200 or -2000 or more or less.
What will its actual size?
2 bytes or change with the value.
Please also mention the reference with your answer. if available.
Microsoft OLE DB Provider for ODBC Drivers error ' 80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]Updated or inserted row is bigger than maximum size (1962 bytes) allowed for this table.
database:microsoft 6.5 SQL
How can I solve this problem
thanks,shay
Hello ,
I would like to know the size in bytes required internally for each datatype MSSQLServer supports.
For eg.
I think for SMALLINT its 2 bytes
Would like to know the size in bytes for
SMALLINT, INTEGER, REAL, VARCHAR, DATETIME, IMAGE, DECIMAL
Thanks..
Here is my code:
Dim oParameter As New System.Data.SqlServerCe.SqlCeParameter("@pMyParameter", SqlDbType.Binary, 3000)
If you set a watch on this object, the size is set back to 510. I have tried resetting the size back to 3000 after construction using oParameter.Size, but it doesn't change from 510. If the command is executed using ExecNonQuery, this causes the bytes to get cut off at 510 bytes and returns the error: Byte array truncation to a length of 510.
Can I insert data into SQL Server 2005 Mobile Edition, into a field of data type binary(3000) using .NET CF 2.0 via SqlServerCe objects?
Thanks for any help.

Hi,
Im trying to create a VERY wide table, with 1,000 columns of type varchar(MAX), nullable.
The CREATE TABLE statement (both in SQL 2005 & 2008), gives the following warning:
Warning: The table "WIDE_TABLE" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit.
When I insert data into the table, filling all columns with small, 10-byte string values, I get the following error:
Msg 50000, Level 16, State 1, Procedure sp_pivot, Line 118
Cannot create a row of size 15034 which is greater than the allowable maximum of 8060.
Id like to verify this observation: each row is created with 2000 bytes of offset data (2 byte * 1000 columns), 125 bytes for null bitmap (1000 columns / 8 bits) and some more wasted? row information. This leaves less than 6K for the data itself. But since not all columns can fit within the page, forwarding pointers in the row need to be created, 24 byte per column, which very quickly add up to more than 8K, thus the error. So the 8K limit is met for much less columns than the max 1024 column restriction.
Furthermore, in SQL 2008, SPARSE columns will not solve the problem (maybe save some metadata? space in case the columns are null, but if not, Im with the same problem again, or even worse, since now each value takes more storage space. The max 30,000 columns in 2008 is only for cases where the column values are really sparse
Is this the right observation? if so, is there a workaround besides splitting to multiple tables?
Thanks,
Aviv.

[Table] | 1 |16KB | 8KB | 8KB | 0KB
i couldnot understand
i) how the system calculate this 16 KB and 8 KB ?
ii) if i changed the VARCHAR(255) to VARCHAR(50) ,will there be difference in size of the table ,if so then how ?
iii) how can i see the change in size of table by reducing the size of datatype ?
can anybody help me ?
I have some code I build 2 weeks ago which I’ve been running daily but it’s suddenly stopped working with the following error.
“The table "tbl_Intraday_Tmp" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit” When I google this there seems to be a related to tables with vast numbers of columns.
My table tbl_Intraday_tmp is relatively small. It has 7 columns. 1 of varchar(5), 3 of decimal(9,3) and 2 of decimal(18,0). The bit I’m puzzled with is it was working and stopped.
I don’t recall changing anything but I wouldn’t rule that out. I ‘ve inspected the source files and I don’t believe they have changed either.

Hi I have an image column (Spectrum) in a Table (ParticleEDS) which is populated with an array of a bunch of INT32's (4 bytes each)
Using TSQL is there any way that I can read each 4 bytes (convert this to an INT) and return this data for a given record (based on ParticleEDSID).
I know that there are 8192 byes (2048x4 bytes) that make up the image column.
I would like the output of the query/stored procedure to be:
Value
------------
1 2342
2 2334
3 3343
.....
2048 1001
I am thinking that the way to do this would be to convert every 4 bytes into an int and create a temporaty table with an integer column which I populate with int and then run a select * on this temporary table.
Does anybody have any pointers on how I can start to do this?
I am using MS SQL server 2008, and i have a table with 350 columns and when i m trying to create one more column its giving error with below message -
Warning: The table XXX has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes.
INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit.
how can i resolve this?
I want to calculate average row size of a record. By based on this i want to add some more columns into an existing table. Here is my table structureCREATE TABLE patient_procedure( proc_id int IDENTITY(1,1) CONSTRAINT proc_id_pri_key PRIMARY KEY, patient_id int NULL, surgeon_name varchar(40) NOT NULL, proc_name varchar(20) , part_name varchar(30), wth_contrast int , wthout_contrast int , wth_wthout_contrast int, xray_part varchar(60), arth_area varchar(30), others varchar(30) , cpt varchar(20) , procedure_date smalldatetime NOT NULL, mraloperrun varchar(20),CONSTRAINT patientid_foreign_key FOREIGN KEY(patient_id) REFERENCES dbo.patient_information (Patient_id)) Now i got a requirement that i have to add two more procedures with different columns.The columns overall size is 195 bytes.I can place those two procedures as seperate tables. I dont want to do that becuase of front end requirements.Here the problem is when the user enters these two procedures information remaining fields will store the null value. I know that when we store the null values into corresponding columns min of 1 byte will be occupied. Please suggest me that shall i include these columns into the above table. If i add these columns is performance will be decreased or not. Waiting for valuable suggestions.

I have a table in a SQL 2005 database that is designed to hold JPG product images for a website. Here is the schema:
create table dbo.Eur_RMISWebInterface_Staging_ProductImages(
product_code varchar(12) not null,
image_order smallint not null,
colour_identifier varchar(10) not null,
image_data image not null,
constraint PK_Eur_RMISWebInterface_Staging_ProductImages primary key clustered (
product_code,
image_order
)
)
Product images are inserted into the table from a database on a remote SQL 2000 server. Here is the script that does that (uses dynamic SQL):
set @SQLCmd = '
set xact_abort on
begin transaction
delete Eur_RMISWebInterface_Staging_ProductImages
insert Eur_RMISWebInterface_Staging_ProductImages (
product_code,
image_order,
colour_identifier,
image_data
)
exec "' + @RMISServerName + '".' + @RMISDatabaseName + '.dbo.Eur_RMISWebInterface_GetProductImagesForWeb ' + convert(varchar(3), @PortalID) + ', ' + @Locale_LCID + '
commit transaction'
execute (@SQLCmd)
About 500 images, each about 20KB, are transferred at a time. Here is the problem - when this script is run manually, all the images are inserted completely. When the script is run as part of a job (that has several other steps), the job step completes successfully and all the images are inserted, but every single one is truncated to the first 1024 bytes of the image. What this ends up looking like on the website is a a narrow strip of image instead of a complete image. Here are some other observations:
- When I changed the "Eur_RMISWebInterface_GetProductImagesForWeb" SP to only return 1 product image instead of 500 it still failed
- The owner of the job is the same Windows user as the user I have been running the script manually as
- I have tried changing the datatype of image_data from image to varbinary(max) but it made no difference
What could possibly be going on???
I have a column in my table that is an Image (blob). The data storedin this blob is basically pdf files. I need a query to determine thetotal size of these blob's in the database. Here is what ishappening, if I run it as below I get 23736000 for a result.select sum(datalength (cast(document AS binary(8000)))) fromplan_reportIf I run it like this select sum(datalength (cast(document ASvarbinary(8000)))) from plan_reportI get 23736000 also as a resultIf I run it like this select sum(datalength (cast(document ASvarbinary))) from plan_reportI get 89010 this as a resultIf I run this: select datalength(document) from plan_report then Iget a result for each row and when I sum those rows I get 5584452854this as a result.I do not believe the first 3 queries are returning correct result setsdue to the limit on the fields (binary/varbinary) and since this is animage field I cannot convert to anything else.....I am out of ideas, and any help you can give me will be greatlyappreciated...

Hi,
I have encountered a query which takes lots of temp tablespace and it fails later.
Initially the temp tablespace was 28GB, we made it to 56 GB but still it fails.
There is just this single process that is running on database.
I tried putting index on the table in query ,but no help.
Can suggest a solution to get size of temp space required or reduce its usage?
I need find out the number of columns in flat file before i process that particular file.
I have file name in @filename variable and file path is @filepath variable.
But do not not that how i will check the column name in before i will process that file.
@filePath = C:DatabaseSourceFilesCAHCVSSourceFiles
And I am using for each loop container to read the file one by one and put the file name in @filename variable.
and my file name like
Product_20120607060930.txt
Product_20130708060930.txt
My file structure is:
ID,Name,City,Country,Phone
1,Riya,Pune,India,454564
2,Jiya,New Jersey,India,454564
3,Riya,St Louis,USA,454564
4,Riya,Belleville,USA,454564
5,Riya,Miami,USA,454564
Now what i have to do is i need to make sure that ID,Name,City,County,Phone is there in flat file. if it is not there then i have to send mail to client saying that file is not valid.
Let me know how i will do it.I need to also calculate the size of flat file.
I receive Error: 3967, Severity: 17, State: 1. Insufficient space in tempdb to hold row versions. We have 8 data files for temp db of 10210 GB size and given 10240 GB as max size.
As MS suggest to calculate the temp db file size and growth rate we need to monitor the perform counters Free Space in Tempdb (KB) and Version Store Size (KB) in the Transactions object.
basic formula: [Size of Version Store] = 2 * [Version store data generated per minute] * [Longest running time (minutes) of your transaction
My report disk utilizations says tempdb is full ? I thonk I need a shrink for the file .
Still I am confused in calculating the size , My perform counter gives me data as such
Free Space in tempdb (KB) 279938496
Version Generation rate (KB/s) 53681040
Version Cleanup rate (KB/s) 53422320
Version Store Size (KB) 258720
Version Store unit count 22
Version Store unit creation 774
Version Store unit truncation 752

I need to calculate the last two columns (noofgrp and grpsize) No of Groups (count of Clientid) and Group Size (number of clients in each group) according to begtim and endtime. So I tried the following in the first Temp table
GrpSize= count(clientid) over (partition by begtime,endtime) else 0 end
and in the second Temp Table, I have
select
,GrpSize=sum(grpsize)
,NoofGrp=count(distinct grpsize)
From Temp1
The issue is for the date of 5/26, the begtime and endtime are not consistent. in Grp1 (group 1) all clients starts the session at 1030 and ends at 1200 (90 minutes session) except one who starts at 11 and end at 1200 (row 8). For this client since his/her endtime is the same as others, I want that client to be in the first group(Grp1). Reverse is true for the second group (Grp2). All clients begtime is 12:30 and endtime is 1400 but clientid=2 (row 9) who begtime =1230 but endtime = 1300. However, since this client begtime is the same as the rest, I wan that client to be in the second group (grp2) My partition over creates 4 groups rather than two.
I'm trying to determine how much space some tables use (SQL2000), and I found 2 suggestions posted earlier, but can't get them to work for me.
The first was
"Right click on the DB in Enterprise Manager, select view then taskpad."
When I try that, I get some of the tables displayed with the info I want, but I can't see them all and can't scroll down beyond the first 22 tables in the database.
The second suggestion:
exec sp_msforeachtable @command1="print '?'",@command2="sp_spaceused '?'"
It says "command copleted successfully, but where does the output to this go ?? Is there something other than "print" I should use ?
The grid pane is empty.
