Write BLOB Data Failed
Oct 9, 2007
Hi,
I have a problem with writing BLOB data into type of 'image' field.
If the data size > ~280 MByte (< 2 GB) the operation failed.
It is appear on SQL Server 2000 and 2005 (MSDE and express also).
Detailes :
column type : image
Server : SQL Server 2005, version - 9.0.3042
technology : OLEDB, from C++ -> CDynamicAccessor
protocol for communication : TCP/IP
Size of the DB : ~3 MByte.
As I see the provider read partially (~267 943 936 byte if all is 280 MB) of data from my ISequentialStream.
Error of OLEDB:
DB_E_ERRORSOCCURED : 0x80040e21
[DBNETLIB][ConnectionWrite(send()).]
General network error.
SQL Server error log entries :
10/05/2007 16:52:53,Server,Unknown,A fatal error occurred while reading the
input stream from the network. The session will be terminated.
10/05/2007 16:52:53,Server,Unknown,Error: 4014<c/> Severity: 20<c/> State: 1.
Entries of SQL profiler :
Error: 4002, Severity: 16, State: 4
The incoming tabular data stream (TDS) protocol stream is incorrect. The stream ended unexpectedly.
I used to set up the bug with contents of a ~350 MB .zip or .mdf file. Everyting is ok when the data <= ~250 MB.
I had ran MS Network Monitor on the server side and not found partially transmitted frames (but I use it on first time).
We try it on another machines, on another LAN with other BLOB (and the bug arised).
I had try 'named pipes' protocol for communication (and the bug arised).
I will be glad if somebody maintain that how can I found the origin of the bug (tools, log options, protokol settings etc.) or
I can present my simple test program (VC 2005 project) and its database (MS SQL 2005).
Best Regards,
Imre

I need some help in SSIS Package I am trying to write a byte array to an image (blob) in DB2 destination. I am getting SQL code -290 Invalid Description, if i set the output column to a byte stream. If I set the output column to an Image data type then I get a different error the package will not at that time even process it errors out right away. At least using a byte stream datatype it errors out when it is about to write to the olebd destination. Anybody have success using BLOB fields in SSIS package data flow? Thanks for any help.

Does anyone have any experience of this type of data please? I have been asked to work on a project where it looks like we will be taking MS Office files and scanned images and storing them in a SQL 2000 db so that they can be aquired by a third party application. I am most intereested in the size of the records as the server may need upgrading, for space and performance.
I am also interested in how a BLOB record is created, is it a particular save process from Word / Excel etc or can you specify to import as a BLOB from a SQL script?
Any info welcomed as i really dont know where to start !!!
TIA

Hi all,It was my understanding (Please correct me if I'm wrong on this!) thatBLOB data actually reside on their own separate pages and a BLOB fieldonly holds a pointer to the location of the actual data, therefore theBLOB data per se would not get written to the log, only the pointerwould be written.If log shipping works by applying the transaction log to the standbydatabase, then what happens to the BLOB data?Related question, how does transactional replication work? Is it alsobased on the transaction log?TIA,Ellen

Hi, I have to migrate an oracle database over to SQL Server 2005. One of the tables has PDF files stored as BLOB. All the ORACLE providers in SSIS do not support BLOB column. What can I use or how can I get the PDF files into my SQL table? The SQL column can be either IMAGE or VARBINARY(MAX).
Thanks,
Les

hi,
i learned that BLOB data types are out-row data by default, i think it means it will not store in the row of table, because the max-length of a col is 8KB.
but will the system store those BLOB data? and is there any way to specify where should it be stored, like tha Partition Schema.
i am using SQL Express, so i hope it works for express.(partition does not work for express)

How do I use the GetBlobdata to get the string representation?
I have tried numerous version of Encoders thinking that
System.Text.Encoding.GetEncoding(Row.TextData.ColumnInfo.CodePage).GetString(b) (where b is the byte array returned by GetBlobData)
But this doesn't work. I have had to resort to converting the field in SQL, so I don't have to deal with blobdata.

Hello,
I have SQL Server 2000 and I'm trying to import data from a paradox v5 database. Everything has moved over fine but the data from the blob fields. When I use the import tool and try connect to a paradox blob field, the import wizard does not "see" the paradox blob field. here is and example.
If I have a table with the following fields.
id char(20)
description char(120)
image blob
the ms-sql import wizard sees
id char(20)
description char(20)
I find this very odd, but I do need a solution. Any Ideas?
TY

Hi! I tried to save some image data, but it get truncated at 8000 (the table column is defined as Image). I then wrote a converter to try ntext-datatype instead, but it gets truncated at 4000.
Error message:
System.Data.SqlServerCe: @3 : String truncation: max=4000, len=4168
The code uses only ADO entity framework for database access. Is there a way to store binary data larger than 8000 bytes? I am running SQL Compact 3.5 sp 1 BETA.

We are debating what is industry “best practice� for serving huge numbers of images in an industrial scale website. More directly, which approach produces the best performance and the best scalability? For example, how do sites like ebay, Amazon, and other large sites handle the millions or billions of images they must deal with?
Store as BLOB in sql server?
Store in /images folder and store url text into sql server?
We always assumed that the second approach is what most sites must do. But do they?
One developer on our team maintains that storing one million or more image files in a directory will most certainly result in poor performance, because the server must scan the directory, searching for the correct file, each time a web request is made. The directory is not indexed (?) so performance must eventually suffer.
Other developer counters that storing millions of images as BLOBs into sql server will result in poor performance and HUGE database. An additional layer of access (webserver to sql server, back to webserver, then to client) causes a delay and performance hit.
Who is right? What do the gurus as the world class sites do?

A little background on what I am trying to achieve first. We are moving to Azure virtual machines and we will have 8 disks on the SQL Server box. I am adding more files to the primary file group and each file will go on its own drive. I am then rebalancing data across these files by rebuilding all of the indexes on the tables which is working fine. No problems so far all is good.
I now have an additional problem. If there is a lob or blob column on the table, rebuilding the clustered index and all the non clustered indexes doesn't rebalance the blob or lob data across the disks such as it does with in row data.
I cannot find any articles on rebalancing lob or blob data because all the articles say to move to a new file group. I do not want a new file group, I just want to use the primary file group where the data already resides, and just redistribute it evenly in the same way that I can in row data which is working fine.
One solution I thought about was to BCP data out of the table, truncate the table and then BCP back into the table which I imagine would have the desired effect of distributing the data evenly over the files.

[Source - chn_employee_vew_test_txt [1]] Error: Data conversion failed. The data conversion for column "Column 42" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
[Source - chn_employee_vew_test_txt [1]] Error: The "output column "Column 42" (136)" failed because truncation occurred, and the truncation row disposition on "output column "Column 42" (136)" specifies failure on truncation. A truncation error occurred on the specified object of the specified component.
I using Locale (People's Republic of China) and code page of 936 (Simplied Chinese GBK) with header row delimiter {CR}{LF}.
I am using flat file import method.
Whenever the server process the Column 42 with value "11,Nanjing Rd.W, China" which contain 'comma' or '.' it will hit error importing with above message. When i manually change the column value to non comma or '.' (11 Nanjing Rd W China) in the flat file it is ok.
I am using SQL server 2005.
Please advise what need to be done to avoid this error ?
Thanks in advance and any idea or suggestion is very much appreciated as i have try to solve this issue for over a week but still not able to find any answer on it.

Hello All,
Thanks in advance for your help.
I am wondering if there is a correlation between the size of a database and the amount of RAM required in the server. Here's what's going on:
NT4.0 SP 6a, SQL 7.0
2-800 MHz Pentium III Processors
512 MB RAM
Swap Files: two, divided evenly between two partitions, min 512 per partition (dynamic)
3- 9.2 GB Drives, RAID 5
SQL Database size: 2.5 GB
The SQL administrators have a scheduled job set to dump the database every four hours, so they have 6 of these dump files per day. Seagate Backup Exec v 6.? backs up those files every evening. Of course, this is a mission-critical application.
As the NT/Hardware administrator, I was tasked to flash upgrade all the hardware that could be flashed. That happened about three weeks ago. Ever since I flashed it, getting the data dumps has been an inconsistent process. Sometimes it works, sometimes it errors out. The error message is " Lost Delayed - Write Data: The system was attempting to transfer file data from buffers to (path). The write operation failed, and only some to the data may have been written to the file."
On and off during the day, you can't even copy a small file on the server without receiving the same message.
Before I flashed the server, it was blue-screening and needing to be rebooted about once every two weeks. Since I flashed it, the server hasn't been rebooted, because it hasn't blue-screened.
The database dumps are about 2 GB. We were thinking that the way the dump process worked was that a snapshot of the data was put into memory before it was written to disk. We thought since the dump size was larger than Physical Memory + Virtual Memory, that that could be causing the error.
What do you guys think?
1. Is dumping the database first the preferred way to get a backup, or should a backup directly to tape be scheduled instead?
2. Do we have enough RAM for the database?
3. Are there special settings we should set for the RAID controller card to maximize throughput for SQL?
Thanks again. I am definitely not a SQL DBA and any information you can provide would be really helpful.
