example sql:

I know how single outer or inner join works in sql.
But I don't really understand when there are multiple of them.

Hi I'm looking to query a table on a database and then iterate over the results in a loop. I believe this is the last part of my script that I need (after finding out threads for passing variables to other scripts and calling functions in other scripts).

Hi -- I have the following SQL query in my UNIX shell script -- but the subquery in the second section is very slow. I know there must be a way to do this with a union or something which would be better. Can anyone offer an alternative to this query? Thanks.

DBIx::Class::Storage::DBI::Oracle::WhereJoins(3pm) User Contributed Perl Documentation DBIx::Class::Storage::DBI::Oracle::WhereJoins(3pm)NAME
DBIx::Class::Storage::DBI::Oracle::WhereJoins - Oracle joins in WHERE syntax support (instead of ANSI).
PURPOSE
This module is used with Oracle < 9.0 due to lack of support for standard ANSI join syntax.
SYNOPSIS
DBIx::Class should automagically detect Oracle and use this module with no work from you.
DESCRIPTION
This class implements Oracle's WhereJoin support. Instead of:
SELECT x FROM y JOIN z ON y.id = z.id
It will write:
SELECT x FROM y, z WHERE y.id = z.id
It should properly support left joins, and right joins. Full outer joins are not possible due to the fact that Oracle requires the entire
query be written to union the results of a left and right join, and by the time this module is called to create the where query and table
definition part of the SQL query, it's already too late.
METHODS
See DBIx::Class::SQLMaker::OracleJoins for implementation details.
BUGS
Does not support full outer joins. Probably lots more.
