In what way is it not working ?
Are you getting an error message, or not
getting the results you expect.
In the latter case, this may be because
you are cancelling the outer join by not
echoing it through all the necessary
points in the WHERE clause.
e.g.
>
> (substr(pcmacaddress,10,2) ||
> substr(smarts.pcmacaddress,13,2) ||
> substr(smarts.pcmacaddress,16,2) ||
> substr(smarts.pcmacaddress,19,2) ||
> substr(smarts.pcmacaddress,22,2) ||
> substr(smarts.pcmacaddress,25,2))(+)=lisa.macaddress
>
makes smarts the deficient table, but
> smarts.giltbis = '2100-01-01-00.00.00.000000' and
eliminates the outer-ness of the join, and loses
any appended rows.
similarly with:
> kompsys.system = syspers.system(+) and
> syspers.giltbis = '2100-01-01-00.00.00.000000' and
the join to syspers ceases to be outer because of
the literal comparison.
