I tried to ALTER TABLE calendar NOCHECK CONSTRAINT ALL and I got this error:
Warning: The table 'messages' has been created but its maximum row size (8321) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes.
I'm not too certain what this error means so I manually deleted the records in this table. I got the same error.
SQL 7
One of my programmers brought an error to me that I need to get some clarification on ...
Its says:
The total row size (24301) for table xxxx eceeds the max number of bytes per row(8060). Rows that exceed the max number of bytes will not be added.
Thoughts ...
Hi,
I used to write the data in a database throught the component. Few days it worked fine and suddenly one day it showed the database is suspect and the file size is 0 bytes but actually is should have written lots of data.
But i have the datafile which shows zero bytes and when i try to attach it it gives an error:
Server: Msg 823, Level 24, State 6, Line 1
I/O error 38(Reached the end of the file.) detected during read at offset 0000000000000000 in file 'D:EorderdatabasePritamdbeorderpritamdb_Data.mdf'.
Connection Broken
Can anyone tell y is this. And it would be really if anyone can tell how to recover the data. The only thing which i have now is the data file which shows zero bytes.
Thanks.
How to count how many bytes were taken per row in certern table?
Which method is the most correct and directly?
Thanks
I'm taking a look at a server to optimize it and need a better understanding of the Memory Available Bytes.
If the graph is showing this @ 100 is that a good or bad thing.
Articles are saying it shouldn't be below 4MB...
Can anyone elaborate?
thanks,

My database has chinese characters in.
Eventually I need to only get the first 50 bytes of the data field, but somehow, I use len('==data==',50), it would catch 50 chinese characters which make 100 bytes ...
can anyone help me?
Thank you very much no matter what the result is ;)
Hi guys,I'm currently trying to insert image into my SQL db.
I have tried a number of methods that were posted online, and so far
with no luck.My current code reads: Dim conn As New Data.SqlClient.SqlConnection() conn.ConnectionString = ConfigurationManager.ConnectionStrings("MainDBConnection").ToString conn.Open() Dim cmd As New Data.SqlClient.SqlCommand("SP_SAVEImage", conn) cmd.CommandType = Data.CommandType.StoredProcedure Dim sImageName As New Data.SqlClient.SqlParameter("@sImageName", Data.SqlDbType.VarChar, 50) sImageName.Value = sImageName Dim sImageType As New Data.SqlClient.SqlParameter("@sImageType", Data.SqlDbType.VarChar, 50) sImageType.Value = fileType Dim sImageData As New Data.SqlClient.SqlParameter("@sImageData", Data.SqlDbType.Image, uploadedFile.Length) sImageData.Value = uploadedFile cmd.Parameters.Add(sImageName) cmd.Parameters.Add(sImageType) cmd.Parameters.Add(sImageData) Dim reader1 As Data.SqlClient.SqlDataReader reader1 = cmd.ExecuteReaderRunning
through debug, everything runs up until the last line, where an error
is caught saying : Failed to convert parameter value from a
SqlParameter to a String I reckon it's to do with the input sImageData being input as a byte array - but I can't seem to find a way around it. Any help greatly appreciated!!
if SQL SERVER 2000 only allow 8060 bytes per row, then how can it store images or CLOB data? Is there a way that would let us change the maximum number of bytes per row? Any help would be greatly appreciated. Thanks.
View 1 Replies View RelatedI'm wondering if there's a way to use the string function replicate() to produce an output greater than 8000 bytes. From the documentation REPLICATE returns a varchar of max 8000 but I'm told there's a way to stop this restriction.
My mentor has been giving me tasks to try and accomplish and for this one I'm to create a stored procedure with no limitations, however I'm stuck at this replicate() problem.
Any help or guidance would be great.

Hi,
We are trying to get a rough estimate of the size of the warehouse in terms of number of bytes. Now I understand that when I say char(2) datatype requires 2 bytes of memory. If this is correct then how many bytes does the following data type need -
1. smalldatetime
2. decimal(14,2)
3. decimal(12,2)
4. int
5. smallint.
6. decimal(9,0)
Also can you explain the byte allocation for a varchar column. Say varchar(20) for example.
Any help is appreciated.

I have a varchar(900) which means that I can use 900bytes, so if I am not wrong if the character is unicode, y only can use 450 because each character need two bytes.I have a databease with a column that use the intercalation general_latin_CI_AI, but I don't know if this intercalation use 1byte per character or use 2bytes per character.How can I know how many bytes need a character of a varchar column?
View 3 Replies View RelatedHello,
I have a field in my SQL Server 2000 with type "varbinary(8000)" which I merge onto my SQL CE 2.0 database. On my SQL CE 2.0, this field becomes "image".
Based on Microsoft's site: http://msdn2.microsoft.com/en-us/library/aa257477(SQL.80).aspx, "image" is used if the size is not over 510; however, when I populate this field in SQL CE, the maximum size that is stored is 510 bytes. I have verified my source data was complete (2622 butes) when again when I check the size of the field after an insert, it had only 510 bytes.
What's the work-around?
Thank you.
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.
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?
Hi All,I have created a table in sql server 2000 where at the time of creatingit, the row size excced 8K.

View 6 Replies View RelatedI have a stored procedure in vb.net that executes a sql statement to retreive a record from a table as xml using "for xml auto". The code looks something like the following:
sql = "select top 1 * from sometable for xml auto"

xmlstring = cmd.executescalar.tostring
The stored procedure runs fine except when it is run by SQL Agent. Then, it only returns the first 512 bytes from the database.
I'm stumped. Does anyone have any ideas? Thanks.

I thought I understand the notion in the Title until I ran the query below. This query inserts a 5000 byte value into two columns in the same record and sql (2008) doesn't complain.
-- drop table table_1
create table table_1(
[mychar1] [varchar](8000) NULL,
[mychar2] [varchar](8000) NULL
)
insert into table_1 ( mychar1, mychar2)
values (replicate('a', 5000) , replicate('b', 5000))
select * from table_1
-- truncate table table_1
I just noticed that using Replicate ('a', 50000) doesn't cause an issue either. I'll be reviewing the replicate documentation too.
Hi,
We have Asynchronous Database Mirroring on SQL Server 2005 SP2 Entprise Edition/Windows 2000 Advanced Server. We noticed that log sent rate is quite low (average 1.3 MB/sec) in most of the cases whereas "Log bytes flushed/sec" is high (1.4 MB/sec) as a result Log send queue keeps on increasing and finally taking all the transaction log space. Our disk queue length is always in range of 0.01. And prinicipal and mirror servers are on local LAN.
I tried on low end server and high end server and in both cases Log sent rate is approx 1.3 MB/sec (Maximum 4 MB/sec).
Is there any limitation on Log sent rate?
How can we improve on log sent rate? Since both servers are on local LAN, network bandwith does not seems to be an issue.
Any help is greatly appreciated.
Thanks,

We have an app that threads together emails coming out of Exchange, using their messageid. To ensure threading works correctly, we need to ensure uniqueness of messageid, which we do with a unique index (we also need to be able to lookup by messageid when a message comes in).
We are currently porting the app from Oracle and PostgreSQL to SQL Server and are having problems with the 900 byte max length of an index. The problem is that the maximum size of a messageid (according to the Exchange docs) is 1877 bytes.
How can we guarantee uniqueness?
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.
Hello!
I have a table that contains a field containing the total bytes for a file. I am displaying the information in a datagrid but need to display the information in MB. If I divide by 1,000,000 in my select statement as such:SELECT cs_fileSize / 1000000 AS MB, cs_fileSize
FROM t_client_spotsI get the following results:
MB | cs_filesize
1 | 1899602
1 | 1782281
I would like the results to be:
MB | cs_filesize
1.89 | 1899602
1.78 | 1782281
Any suggestions?

This is a question that I have not had an opportunity to test. Was wanting to know if anyone in the SQl world knows the answer. In SQL 2K and 2005 your rolls are limited to 8060 bytes without using varchar(MAX). My question is do you have to specify varchar(max) before your roll can exceed 8060 or does SQL 2005 exceed without specifing varchar(Max). Also does SQL 2005 expand it across multiple pages automatically. Please assist if you can.
Thanks
Hello, I received an error while attempting to create a table similar to the following...

)
First of all, field names have been changed to protect the innocent. Second, I did *not* create this table...I'm troubleshooting issues with a previously created table. I've no idea why almost every field needs to be an NVARCHAR data type of that size. Finally, as you can probably guess, I'm getting this error on a SQL Server 2000 database. (Yeah, it's past time we upgraded to SQL Server 2005 at least...explain that to management, please. I suggest you speak slowly and use small words.)
Anyhow, the error is "Warning: The table 'ExampleTable' has been created but its maximum row size (13348) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes."
Am I misunderstanding how the row size is calculated? How is SQL Server getting 13,348 bytes from the above statement?
Any and all constructive suggestions/ideas are much appreciated! Thanks!
Given a 4 byte integer, how to extract each individual byte and format with a period separating them? As an example, if MSB is 1, followed by 2, then 3 then 4 then how can the four bytes from this integer be formatted and displayed as 1.2.3.4?
View 15 Replies View RelatedHere 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 Guys,
i've found many threds with SSIS buffer errors but non of them seems to work, or have a good solution. i'l explain the story short.
i've got a DB server running on Windows 2003 R2 Enterprise with 10GB RAM 20GB Virtual memory with same spec another machine for the web server.
both machines have "Lock Memory in memory" group policy enabled for
Network Service
System
DomainSQLServiceAccount (in DB server)
and in the DB memory "awe allocation" is also enabled.
both servers have /PAE /3GB switches enabled in boot.ini file
problem: i run all my SSIS packages in the web server through IIS. so the processes are devided between DB and web server. i.e SSIS service is also running in web server.
when i run packages under load (transforming - 200,000 records) i get buffer allocation errors.
A buffer failed while allocating 10485760 bytes.
Error Code = -1073450990
all packages i run i have set the default buffer temp to my web servers e: emp (got 260GB space left). and defaultbuffer size is 10mb with 10,000 defaultbuffermaxrows.
funny this is when it hit 8.33GB (approx 875 files) i get the above error message. it always seems to give me errors after 8.33GB.
Note: all packages run in IIS (w3wp.exe). i'm configuring my new production boxes. the old production with similar envirnment (less speed) work with the same data and packages fine under load.
new production machine got more memory than the old machine but i get memory error (buffer). it doesn't even use up all available physical memory, only about 3gb (max), then start buffering to disk.
any help would be greately appreciated.
i also got
The system reports 31 percent memory load. There are 10734981120 bytes of physical memory with 7326126080 bytes free. There are 3221094400 bytes of virtual memory with 283840512 bytes free. The paging file has 12661686272 bytes with 9633767424 bytes free.Error Code = -1073450991
this was before i increased virtual memory to 20gb(from 4gb).
Any ideas i can try out?
do all sql data types consume whole numbers of bytes? We have an app that might be best suited to bit manipulation at the nibble rather than byte level.
