Report Template? For saving into the database?

rbuser

Hi,
I would like to know the difference. The TppReport.Template property is used
for report saving into the database into the Memo or BLOB format.(At least
that is what yout documentation says.) But nowhere in the demos provided
this property is used for saving into database. Instead all saving there is
performed through the ReportExplorer and ItemsTable. (But data field type
must be "LONG"!!!). Is there a difference?

Thanks.

The Report.Template is a Delphi object. You can use it to save to database
or file using its interface. When you call Report.Template.SaveToDatabase,
it will try to stream the report template to the database using the
DataSettings you have configured on the Report.Template.DataSettings. Then
we rely on Delphi and code the saving of the report by writing to a stream
on the BLOB field, which you have defined as LONG on your particular
database. Some databases are different, on some you have to specify LONG as
the datatype, some as BLOB and some as Image, etc. just be sure it works
when you write a BLOB stream to the field and it works using Delphi. All of
our end user database demos have SQL scripts or ReadMe docs which describe
the database types that we have successfully used when saving a report
template to the Template field on the database table. Check those out to see
what we do in our examples and you should use the same type as we do.
