So, sqlldr cannot load both the records. This eliminates duplicate records from being... (1 Reply)
I feel stupid for asking this because it seems that MYSQL code isn't working the way that I think it should work.
Basically I wrote code like this:
select * from `Test_DC_Trailer` HAVING max(DR_RefKey);
Where the DR_RefKey is a unique numeric field that is auto iterated (like a primary key)... (7 Replies)

ModPerl::Global -- Perl API for manipulating special Perl lists
Synopsis
use ModPerl::Global ();
my $package = 'MyApache2::Package';
# make the END blocks of this package special
ModPerl::Global::special_list_register(END => $package);
# Execute all encoutered END blocks from this package now
ModPerl::Global::special_list_call( END => $package);
# delete the list of END blocks
ModPerl::Global::special_list_clear( END => $package);
Description
"ModPerl::Global" provides an API to manipulate special perl lists. At the moment only the "END" blocks list is supported.
This API allows you to change the normal Perl behavior, and execute special lists when you need to.
For example "ModPerl::RegistryCooker" uses it to run "END" blocks in the scripts at the end of each request.
Before loading a module containing package $package, you need to register it, so the special blocks will be intercepted by mod_perl and not
given to Perl. "special_list_register" does that. Later on when you want to execute the special blocks, "special_list_call" should be
called. Unless you want to call the list more than once, clear the list with "special_list_clear".
API
"ModPerl::Global" provides the following methods:
"special_list_call"
Call the special list
$ok = special_list_call($key => $package);
arg1: $key ( string )
The name of the special list. At the moment only 'END' is supported.
arg2: $package ( string )
what package to special list is for
ret: $ok ( boolean )
true value if $key is known, false otherwise.
since: 2.0.00
"special_list_clear"
Clear the special list
$ok = special_list_clear($key => $package);
arg1: $key ( string )
The name of the special list. At the moment only 'END' is supported.
arg2: $package ( string )
what package to special list is for
ret: $ok ( boolean )
true value if $key is known, false otherwise.
since: 2.0.00
"special_list_register"
Register the special list
$ok = special_list_call($key => $package);
arg1: $key ( string )
The name of the special list. At the moment only 'END' is supported.
arg2: $package ( string )
what package to special list is for
ret: $ok ( boolean )
true value if $key is known, false otherwise.
since: 2.0.00
Notice that you need to register the package before it is loaded. If you register it after, Perl has already compiled the "END" blocks and
there are no longer under your control.
