Hi All,
This thread is going to be a discussion basically bringing out more information from the experts on cron jobs and the associated file handles.
So, here is the question.
There is definitely a constant ' n ' as the maximum number of file handles alloted to a process ' p '.

- a semaphore is a variable with a value that indicates the... (1 Reply)

DBIx::Class::Storage::DBI::Oracle::WhereJoins(3) User Contributed Perl Documentation DBIx::Class::Storage::DBI::Oracle::WhereJoins(3)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.
