MSSQL Reports on InterBase and vice versa

edited September 2008 in General
Hi list,

as I previously stated we have customers using InterBase databases as well
as customers using MS SQL server.

We're creating a single report using MS SQL server and then provide the
binary of the report to our customers.

Most of the time this works flawlessly but on some occasions it simply
won't work - mainly because of InterBase problems I figured.

Ok, so much for the background.

I now created a report using the MS SQL server which needs a table twice.

f.e.

select TableA.X1, ta2.X2
from TableA, TableA ta2
where TableA.Column = ta2.Column2

This works flawlessly on an MS SQL server but not on an InterBase Server.
If I change the query the following way, it's working perfectly:

select ta1.X1, ta2.X2
from TableA ta1, TableA ta2
where ta1.Column = ta2.Column2

That seems to be because InterBase needs any occurrence of a table to have
an alias when the table is needed more than once.

If I create the report using the InterBase database, everything works
fine, because then the alias' are added correctly.

How am I able to use this MS SQL server on an InterBase database?

I'm using version 10.06 of the ReportBuilder with Delphi 2007.

Kind Regards,
Christoph

    Hi Christoph,

    For the reason that you describe below (different DB's requiring different
    SQL dialects), ReportBuilder is designed to handle one database at a time.
    I would recommend possibly creating two different templates of the same
    report for each database to rule out the possibility of issues occuring
    while execution.

    Hi Nico,

    thanks for your reply!


    I was hoping that I could skip that step and let the ReportBuild do the
    work for me. :)
    Is it possible - for a future version - to implement some DB specific
    syntax stuff? So if a report was created using db1 and then run on db2,
    that the sqls (which you generate dynamically I guess?) are changed to
    match db2s dialect?


    Regards,
    Christoph

    Hi Christoph,

    Thanks for the suggestion. This would be a very helpful and powerful
    feature and we will consider it for a later release of ReportBuilder.
