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 .
The microsoft JDBC driver doesn't accept CLOB & BLOB field.
Does anyone know about this problem ?
Is it possible to found another driver that works correctly and that is free ?
Thank's
Source System : Oracle
Target System : Ms Sql Server 2012
ETL Tool Used : SSIS
My source data is present in XML File which is stored in CLOB column Of Oracle. CLOB column is compressed.I need to Migrate data by Uncompressing XML to SQL 2012 .
Do I need to define XML column in SQL Server 2012 for storing Uncompressed CLOB values ?
How to uncompress the clob and extract the required data from XML using SSIS .
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,

we recently got a scenario that we need to get the data from oracle tables which is installed on third party servers. we have sqlserver installed on ourservers. so they have created a DBLINK in oracle server to our sqlserver and published the DBLINK name.
what are the next steps that i need to follow on my sqlserver in order to access the oracle tables ?
Using a code snippet borrowed from a co-worker, I have put together a query that, among other things, pulls a list value out of an xml clob field and displays it in the query results. My query as it stands right now is below, followed by a snippet from the xml clob that I am pulling from.
select * from
(Select Wtr_Service_Tag, Wtr_Tran_Origin, Wtr_Send_Date, Wtr_Receive_Date,
to_char(substr(wtr_req_xml,instr(substr(wtr_req_xml,1,8000),'SID')+8,12)) Asset_Tag
from ws_transactions
Where Wtr_Service_Tag In ('20458749610')
[Code] ....
This query is only able to pull the first value in the list.
I have two questions...
[1]How can I edit this query to pull all of the list items when there are more than 1? I have another field, in a separate table, that I can pull from to get that number.
[2]This one may be more complex. As currently written, the query pulls a fixed number of characters from the xml clob and either returns not enough data, or too much because the values I need to pull could be of varying lengths. I have no way to query what those lengths might be.
I have two tables Encounter & Encounter_History. They have same columns. One column is of type CLOB. My requirement is to retrieve all the distinct records from both the tables with order by a date column. But problem is, UNION does not work in case of CLOB data type.
I know it will work if I use UNION ALL, but it returns duplicate records.
Please give me suggestion, how to solve this problem.
For example: The following query does not work since column1 is a CLOB data type
select column1 from table1
union
select column1 from table2
Thanks
I'm attempting to move data from an Oracle table to an Access table using an Oracle stored procedure in DTS. The problem is that you can't pass parameters to an Oracle stored proc when its called in a data pump task. Is there a way to pass global variables into an Oracle stored procedure which retrieves data and moves it to an Access database? Maybe in an Active X task? We are required to use an Oracle stored procedure by our DBA's or else I'd just pass the variables into a SQL string and use it in the data pump task.

Can I create ODP.NET connection in my SSIS connection manager. I had downloaded and installed ODP.NET on my server provided by oracle. The idea is I need to test this provider and see what is the difference connecting oracle database and the data load speed.
thank you
I am trying to execute oracle procedure (anonymous block) with input and output parameters from ms sql code and return 2 values back:a number and a string.I am using **EXEC() AT** to execute oracle code and return a string back to ms sql. It works fine when returning numbers, but if I add a string output parameter, I am receiving an error:Msg 0, Level 11, State 0, Line 0...A severe error occurred on the current command. The results, if any, should be discarded.
The server log has the following entry in exception.txt:
Exception 0xc0000005 EXCEPTION_ACCESS_VIOLATION reading address 00000005031C07E0 at 0x0000000070F9C183
There is also a SQLDump file generated:
* BEGIN STACK DUMP:
* 10/28/15 12:45:38 spid 63
* Exception Address = 000000005040C183 Module(MSVCR100+000000000003C183)
[code]....
It looks like the problem is in passing varchar2 from oracle into ms sql. I had logging code in oracle block, and it works fine. I have found a few examples of using **exec() at** but there is always only integer output passed back.
Hi everyone,I encountered an error "Need to run the object to perform this operationCode execution exception: EXCEPTION_ACCESS_VIOLATION" When I try to import data from Oracle to MS SQL Server with EnterpriseManager (version 8.0) using DTS Import/Export Wizard. There are 508 rowsin Oracle table and I did get first 42 rows imported to SQL Server.Anyone knows what does the above error message mean and what causes therest of the row failed importing?Thanks very much in advance!Rene Z.--Posted via http://dbforums.com

View 1 Replies View RelatedI have a large table with email column. I need to grant select access to this email column to many users but the actual email should not be visible to those users. I thought of following options:
1.Create an indexed view with that column encrypted and then grant access to users.While searching by email, their search text will also be encrypted and then matched with view column.Problem with this is that I have to create indexed view because most searches will be on Email column and table size is pretty big,20 m records. I don't prefer indexed view in general.
2. Add another column to table with encrypted email and grant access to that column to users. Problem with this is that it will increase table size and i'll need one more index.

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.

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?

How to implement distinct storage tiers on SQL Remote BLOB Storage (RBS)?
I want to use this SQL Feature to move files(images, videos, pdf files) from a database to a distinct database dedicated to RBS. Then I want to have several storage tiers, where objects will be saved and moved according access frequency. Old data will be arquived in cheap storage, but it must be always accessible if needed.
Description:
- 1st and main tier: new and frequently accessed objects stored in high performance storage;
- 2nd tier: automatically move older or less accessed objects to an inexpensive and different storage tier;
- in all cases, all objects must be accessible to all users, but accessing to archived objects(2nd tier) will be much slower;
I am using SqlServer 2000 and Jdbc connectivity in my application on windows.So, when i execute a query on Sqlserver database as :
Select * from DBO.RS_TABLELOB where Rep_sync_id > 15 and Rep_server_name != 'replicator' order by Rep_sync_id;
This problem is only with the BLOB data types in table RS_TABLELOB.
Then i got an error as:
