Openquery - truncation problem (converting data from Oracle 10g to SQL 2005)

Posted By:      Posted Date: September 29, 2010    Points: 0   Category :Sql Server

I am having problems with data truncating when inserting into a SQL 2005 db from Oracle 10g- using openquery and a linked server.   For instance, if I run something like:

insert dbo.CWDocumentStaging
select * from openquery(LK_Snomass,'select RSFORM.REPRESENTATION as REPRESENTATION

The results of the blob data are only 202 hexademical characters in length.  And then when I convert it to varchar, the results are cut-off.  For instance, on a particular test record that I converted, here is what I have in the SQL database (using):

select convert(varchar(max), DOCUMENT_TEXT), DOCUMENT_TEXT from dbo.CWDocumentStaging

I get the following:

for Document_Text, I get the following:


then for convert(varchar(max), DOCUMENT_TEXT):

If I insert the data running the query against the linked server directly, the data does not truncate

Problem using SSIS to move DB2 data to Oracle



I will need your advice on a SSIS package which moves IBM DB2 (for z/OS V7) data to Oracle (AIX 10g). Thank you in advance.

Basically, this is a very simple SSIS package (created by SSIS import / export wizard) and just maps column by column. I used IBM OLEDB provider for DB2 to connect the source and Oracle Provider for OLEDB to connect to the destination.

The problem I ran into was that if the DB2 source value contains special (or invisible) characters then this value will be converted to a SPACE (' ') value on Oracle. To be more detailed, take the following example:

On DB2, value  000002D0000002D7 (EBCDIC HEX codes). This is actually a value of a column defined on DB2 as CHAR(8). Please note HEX '00' in EBCDIC stands for NULL and HEX 'D0' stands for character 'K';

On Oracle, this value will be stored as a SPACE (or a string of SPACEs) after data move.

On both DB2 and Oracle this column was defined as CHAR(8).

I guessed this was related to a code page issue, so I tried a few different code page to set for the source property (by setting the DefaultCodePage of the DataFlow source property), I used code page 37, 500, etc... All resulted in the same Oracle value.

The character set on DB2 is EBCDIC and the one on Oracle is ALT32UTF8. I guess it was the source provid

Converting Crystal Report 2005 to 2008 - Please Tell Me I'm Stupid :)


Hello peeps,

  I have a series of Crystal Reports that I can view/edit using Visual Studio 2005 with no issues.  The method I'm using is to simply click on the *.rpt file and it opens in the VS crystal editor with no issues.  The problem I'm having is that we are upgrading to Visual Studio 2008, and when I open the *.rpt file in 2008 it opens as a binary file.  I guess I'm used to everything else in Visual Studio prompting me to convert the older version to the newer version, so I'm not sure what to do in this case.

  Is this normal?  Is there an easy conversion method that I'm simply overlooking?  Am I screwed?  Who invented liquid soap, and why?

Answers to any of these questions would be greatly appreciated...
