DBArchiveReader

rbuser

Hello

I've many reports in an Oracle 8i BLOB field through DOA. Upgrading to RB7 I
saw the TppDBArchiveReader and tried through a demo app with DOA to preview
them. Unfortunatelly I get an AV upon execution of the
TppDBArchiveReader.Print method. I do supply "TOracleSession >
TOracleDataSet > TDataSource > TppDBPipeline >
TppDBArciveReader.DatabaseSetting....." sequence. Am I doing anything wrong
?

It shouldn't AV. Are there fields defined on the pipeline? What is the
field type that you are using in the Oracle database for the archive data?
We use Long as the field type for the report templates in the Oracle end
user report solution. How have verified that you can print the archives by
loading the database blobs to a file then using the standard file based
TppArchiveReader to print the archives? If you have an example where the
archive reader works but the dbArchiveReader doesn't then send us an example
to support@digital-metaphors.com They both rely on the same ancestor, so
they should either both work or both not work, theorectically from the
class' implementation perspective. If only the DBArchiveReader doesn't
work, then it most likely is that the data connection to the database
archives is not correct, but we can take a look at your example if this is
the case and see what is causing the problem.
