Sybase to Oracle conversion: Problem loading sybase image data into oracle blob

Sybase to Oracle conversion: Problem loading sybase image data into oracle blob

Post by Dwayne Lew » Tue, 07 Nov 2000 13:00:56


Help !!!!

I am involved in a Sybase to Oracle conversion and one of the Sybase
tables uses an image datatype column.  I unloaded the data from sybase
and can load the rows into Oracle using sqlloader without any errors.
The data is getting loaded into a table with the "image" data being
loaded as a blob datatype.   The image data that was in sybase was
basically free form text.  When I run a select * on the Oracle table,
I can select on the other columns but I cant see the blob data.

I don't think I can convert the data in Sybase before unloading it.  I
have tried other datatypes such as long and clob with any success
also.

Any suggestions would be greatly appreaciated.

thanks,

Dwayne,
Hello, interesting you just posted this question - I in fact faced a
similar problem when working with binary data types. After a lot of
looking (since most of the tools I have are not that friendly), I
started using a produuct called Schemer Advanced. It is avaialble from
a company called Appligator (http://www.appligator.com). This product
has made my life so much simpler as I can connect to all my ODBC/OLEDB
data sources from this application and even copy and paste data/table
stuctures/entire databases on the fly. If there are types that don't
align such as the binary ones in my case, I can define what they should
be as it brings up a wizard. Anyway - hope this helps you out! here is
a link to the direct product details page of that application...

Cheers!

1. Sybase to Oracle [connectivity PLUS Data load] on Solaris

I am relying on the Sybase Masters [GURUS], so please help me out

Can Oracle 9i load data directly from Sybase 11.5?

I know one can load data via data loaders, but I want know can one
directly establish connection using something like "DTS" functionality
available in MS-SQL server
If yes, how can this be achieved?

I am aware of gateway documentation that allows Oracle to talk with
Sybase, but I do not have full knowledge of how this is achieved.

Can someone please provide any information on this gateway topic?

I luckily got an URL from Oracle web site:
http://otn.oracle.com/docs/products/gateways/doc_library/92/Solaris/t...
(after you log in) where it states clearly how one can write PL/SQL
program to fetch results in Sequential mode, but my question is about
performance. Is fetching data using of PL/SQL is faster or bcp'ing out
data from Sybase and then loading this data using "data loader" is
faster. I am talking of data that may be around 3,000,000 rows per
day. Has anyone worked on this system? Is yes how can you relate the
performance using both methods

I am aware in Oracle 8i and 9i, in Supplied PL/SQL packages UTL_FILE
package one can create an output file from stored procedure in Oracle,
but in Sybase we do not have this functionality. Only one solution is
to "bulk" copy data from Sybase and load it in Oracle using data
loader.

Can one use C-DBLIBRARY with PRO*C programs to link Sybase with
Oracle?
