I have an ORACLE server say "A". I have a SQL Server named "B". In SQL Server I have a table named "test" who contains only one field named "aa" which is "BIT" type field. I want to query this table of "B" from "A" interface through Oracle's DB Link and ODBC dsn for Sql Server. But it gives error. If I changed the data type of field "aa" to "int", then it reads easily. Please suggest.
View 7 Replieswe 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 ?

View 2 Replies View RelatedHi all,
I have a column in SQL server which is of type ntext. Selecting the specific column to view it in report builder, an error message appears with the following description:
- Cannot run this report. The grouping expression 'nameofcolumn' returns the datatype binary. The Grouping Expression cannot return binary data.
Report Builder recognises this as if it was an image...
Thanks in advance!
Here is my task I am storing pdf's in sql server. I would like to retrieve the binary data from sql server and write the pdf content into an existing aspx page to the appropriate pageview section. What is the best way to handle this. The code works below but it loads a new browser with the content. I need it to appear in it's tabbed section in the original aspx file. Any assistance you can give me would be greatly appreciated.
Thanks Jerry

hello.
i have a _CommandPtr that has the type CommandTypeEnum::adCmdTex, and the CommandText a query("Select * from Table_1") and this select returns one row that has a binary data in it.
Code Block
_CommandPtr pCommand;
//Create the C++ ADO Command Object
pCommand.CreateInstance(__uuidof(Command));
pCommand->ActiveConnection = this->pConnection;
//Make the ADO C++ command object to accept stored procedure
pCommand->CommandType = CommandTypeEnum::adCmdText;
//Tell the name of the Stored Procedure to the command object
pCommand->CommandText = _bstr_t("select * from Table_1");
//get recordset
pRecordset = pCommand->Execute(NULL,NULL,CommandTypeEnum::adCmdText);
BYTE* buffer = NULL;
if(pRecordset != NULL)
{
while (!pRecordset->GetEndOfFile())
{
VARIANT var = pRecordset->Fields->GetItem("test")->Value;
void * pData = NULL;
SafeArrayAccessData(var.parray, &pData);
long size = GetArraySize(var, NULL);
buffer = new BYTE[size];
memcpy(buffer, pData, size);
SafeArrayUnaccessData(var.parray);
pRecordset->MoveNext();
}
pRecordset->Close();
}
where:
Code Block
long GetArraySize(const VARIANT& var, long * nElems)
{
if ( !(var.vt & VT_ARRAY) ) return -1;
long size = 0;
long dims = SafeArrayGetDim(var.parray);
long elemSize = SafeArrayGetElemsize(var.parray);
long elems = 1;
for ( long i=1; i <= dims; i++ )
{
long lbound, ubound;
SafeArrayGetLBound(var.parray, i, &lbound);
SafeArrayGetUBound(var.parray, i, &ubound);
elems *= (ubound - lbound + 1);
}
if ( nElems ) *nElems = elems;
size = elems*elemSize;
return size;
}
I enter in VARIANT var = pRecordset..... and if gives me a value... but when I put it in Memory explorer in VS, i only see this data " fe ee fe ee fe ee fe ee fe ee fe ee fe ee ...fe ee" and of course it brakes at
SafeArrayGetLBound(var.parray, i, &lbound);
Can someone tell me where I am doing a very bad thing?
P.S. I was able to read the binary data from the server using C#.NET 2.0.
Hi Guys,
I've been strugling with this problem all morning today.
Basically I store images in SQL Server 2000 database and then whould like to show them with
<img src="viewImage.aspx?image_id=10" border=1>
My table structure is setup this way
TABLE [userImages] (
[imageFilename] [nvarchar] (128) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[imageContentType] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[imageFileSize] [bigint] NULL ,
[imageFileImage] [image] NULL )
and in viewImage.aspx I have:
if (dr.Read())
{
Response.ContentType = dr.GetString(dr.GetOrdinal("imageContentType"));
Response.BinaryWrite( (byte[]) dr["imageFileImage"] );
}
I have no prolems retrieving the data from DB. But the image does not display(in IE it shows a broken link image)
What's even more puzzling is I CAN display the same image from HDD like so:
FileStream fs = File.OpenRead("D:\my_image.png");
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
Response.ContentType = "application/octet-stream";
Response.BinaryWrite(buffer);
Am I missing something very obvious. I tried playing around with different ContentType's same result.
In my case I am forced to store images in the DB.
I've seen other examples on the net and theirs work. Please help.
Sincerely,
Vlad Orlovsky

This just happened today and I dont know why. I have a database on a SQL server 2005 database, that has a table called photos. It contains image data, but not the column says <Unable to read data>. But before that I get an error when I try to execute the table to retreive the data. The error is below. SQL Execution Error:Executed SQL statement: SELECT ID, AlbumID, Caption, BytesOriginal, BytesFull, BytesThumb FROM PhotosError Source: System.DataError Message: Invalid attempt to Read when reader is closed. This happens with SQL Server Management Studio, and Visual Studio 2005 when I try to access it. I tried two computers so its not that. Any help or insight would be appreciated.
View 2 Replies View RelatedHi I've followed a tutorial on how to write and read varbinary(max) data to and from a database.

I have a local transaction,
BEGIN TRAN
INSERT Z_Test SELECT STATE_CODE FROM View_STATE_CODE
COMMIT
View_STATE_CODE points to remote SQL server named PROD. There is error when I run this query:
Server: Msg 8501, Level 16, State 1, Line 12
MSDTC on server 'PROD' is unavailable.
Server: Msg 7391, Level 16, State 1, Line 12
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.
OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d01c].
It looks like remote server is not available inside the local transaction. How to handle that?

Hi,
Which is the best way to transfer data from SQL server into Oracle?.
Thanks in Advance,
Ravi
Hi,
I created SQL Server package and schedule the job. SQL Server allows us to connected different database for e.g. for oracle using "Oracle Provide for OLD DB" to retrieve our database. A link is create between this database which move the data to SQL Server. I'm sure there is no issues in the link, as I'm using it to retrieve several oracle database which contains both Arabic and English data.
But after Importation it is showing Junk values. Please advise me what step I should take next.

I need some help regarding the data access.
I needs to access some data from tables which are in oracle and load it into sql server tables.
Please let me know the process for this.
Thanks in advance.
Ok, we have built a data mart using SSIS etc...for transformations and loading.
Our biggest single problem we have currently is loading data from an Oracle server to our SQL server. Some tables from oracle run fine when retrieving the data but there is one particular table that just doesn't load fast enough (9 million records take over 12 hours). It seems that we are idling alot and its not always running.
Can anyone help with this problem?
