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
How to access the XML, CLOB and BLOB Oracle data through linked server from SQL Server 2012?
I want to retrieve XML, CLOB and BLOB data from SQL Server 2012 through Oracle Linked server .
Can someone please show me an example on how to read & write blob data to a Database? For example if I have the query below (Northwind), how do I actually place the blob item in a picture box on a windows form?SELECT Picture FROM CategoriesWHERE CategoryID = 5
View 2 Replies View RelatedCan someone please give me an example in C# on how to retrieve an Image from a Table and store i into a Picture box on a windows form? In addition, how to insert a blob record into a table as well.
View 4 Replies View RelatedDoes 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

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)
1. How many blob data types can be defined in a table on SQL Server 7.0
2. What is the max size for a blob data type.
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,

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.
Hi all,
I am trying to store binary datafiles into a SQl Express table. However I can not find the BLOB data type when I am designing the table. Are we limited to using that kind of data type in the Express edition? Thanks.

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.
I am having a problem with MMSQL BLOB with VB, Sorry to say I am new in Programming using VB 6 and MSSQL and I have never touch BLOB in my live.
I just wish anyone could give me any ideal, like, white pages, or manual on how do I insert BLOB data (Images) to MSSQL 2000 database using VB 6. I need to know exspecially the VB Code and the SQL Portion if you have a store procedure code for that it will be nice.

I have created a simple package that uses a sql command to pull data from an oracle database and inserts the data into a sql 2005 table. Some of the data fields that i am pulling from contain two digits after the decimal point, however this data is lost when it gets into sql. I have even tried putting the data into a flat file, and still the data is lost.
In the package I have a ole db source connection which is the oracle database and when i do the preview i see all the data I need. I am very confused and tried a number of things to get the data into sql, but none work. Any ideas would be very helpful.
thanks
OK so there is some data in an Oracle DB that I need to query and analyze. Unfortunately, the criteria for selecting/grouping the data is stored in a MS Sql Server DB. This cannot be changed.

Any idea how I can get the data from these two DBs to talk to each other? Thanks.
There is any tools or products that allow Oracle Users to access SQL 2000 data in realtime? I know how to go in the opposite direction using linked servers, but am not sure on this direction,

Currently, I am working SSIS project that its data source from ORACLE 9i. I installed full SSIS in server and also ORACLE. So, I have three connections available in server. They are the following below.
Oracle Client
Microsoft OLE DB Provider for Oracle
Oracle Provider for OLE DB
The problem is the three component can not recognize parameterization and ORACLE store procedures.
Finally, I executed the store procedures by ORACLE package from command prompt (bat files). So, the command execute from SSIS package.

I am using Import and Export wizard and seeing a very weird behaviour.
I am able to choose 'Microsoft OLE DB Provider for Oralce' and provide server name, username/ password. The test connection results in a success. However when I try to move to next window/page by clicking next I get invalid oracle error ora-01017 - invalid username/ password.
what is going on here?
Hi,
how do you pass parameters into a SQL statement to run in an Oracle database when you use the OracleClient Data Provider?

I have a column in an Oracle source system with data type NUMBER(38,2). The value "-0.01" is causing problems when trying to import into a SSIS data-flow.
The only way I can import this into my data-flow is by using a Datareader connection manager using the ODBC Data Provider. My DSN is using the Oracle ODBC driver.
If I try and use the "Native OLE DBMicrosoft OLE DB Provider for Oracle" I get an error: "The data value cannot be converted for reasons other than sign mismatch or data overflow"
Judging by this post: http://microsoftdw.blogspot.com/2005/11/final-storyhow-to-get-data-out-of.html there aren't really any other combinations to try that will bring my data in as I want it.
I don't want to use ODBC though as:
Its an old technology
Its slow
I have to deploy an additional DSN.
Can anyone tell me why the other options don't work? Why does Microsoft OLE DB Provider for Oracle have a problem with "-0.01"?

I am using Reporting Services 2005, Visual Studio 2005, and Oracle 8.x client.
I have an issue when previewing the report in Visual Studio. I do not receive any errors€¦.. I just don€™t see any data. The strange thing is when I deploy the report and run the report in Report Manager there is data.
I added the TNS and I set the credentials.
Hi,
I'm very new to SSIS so excuse any ignorance...
Im trying to update a set of records in an oracle table based on the results of a query against a SQL Server 2005 table. I would prefer not to run the update query for each result in the source query (but will do it if only way possible), so I have built a script task which builds a comma separated string of Ids that I can use in an in clause... Hence the query I want to execute is of the form:
update MyTable
set STATUSID = 2
where ID in ( 3,4,5,6 )
When I try and execute this query using an 'Execute SQL Task' in debug mode the package gets 'Stuck' on this task. The task turn yellow as though it is executing but never continues - no errors either.
Is it possible to execute an Update statement against Oracle using the Execute SQL Task? Any suggestions for alternatives?
Thanks for any help...
Scott..
hi,
i have 2 user defined variables one as integer and the other as string in my SSIS package.
am using these variables to update a row in one of the oracle tables I have.
update A set LOADED=@rows where sudit='" + @audit + "'
I declared @rows as Int32. But LOADED is declared as number(7,0). Due to this the row does not get updated.
Can anyone please suggest a way to resolve this issue and update the row. Thank you in advance.
We have some columns in a table where the date is stored as 19980101 (YYYYMMDD). The data type for this column is NUMBER(8) in Oracle.
I need to copy rows from Oracle to SQL Server using SSIS. I used the Data Conversion transformation editor to change it to DT_DATE, but the rows are not being inserted to the destination.
On Error, If I fail the component, then the error is :
There was an error with input column "ORDER_DATE_CONV" (1191) on input "OLE DB Destination Input" (29). The column status returned was: "Conversion failed because the data value overflowed the specified type.".
