MySQL Perl script to extract last date field (yyyy/mm/dd)

Hi Friends,

I've a special requirement, even though I know how to implement this using shell scripting, current requirement is PERL, in which I'm not much familiar !!!.

I've a record, which has around 200 fields, out of which I need to extract only one date value from the 97th field (this field itself has many comma seperated values including date values). Below is one such an example record (observation need more attention to identify fields).

field1, field2,.....,field96,
("2008/12/17 2009/03/16 0.000000 0.000000 2009/03/16,
2009/03/16 2009/06/15 0.000000 0.000000 2009/03/18,
.......................,,
2009/03/16 2009/06/15 0.000000 0.000000 2009/03/18"),
field98,.....,field200

My requirement is to extract the second date field (marked with blue, underlined) from the last sub-field (this is also comma separated) of the field 97.

Any help would be much appreciated on this challenging task!!!

Thanks in advance / Mysore Ganapati.

__________________________________________________________________________________________________________________________________________________

NAME
platform::shell - System identification support code and utilities SYNOPSIS
package require platform::shell ?1.1.4? platform::shell::generic shell platform::shell::identify shell platform::shell::platform shell _________________________________________________________________ DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell. This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only requirement is that the other shell (identified by its path), is actually executable on the current machine. While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run 32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers. For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed packages, versus the architecture of the shell running the repository software. COMMANDS
platform::shell::identify shell This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell. platform::shell::generic shell This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell. platform::shell::platform shell This command returns the contents of tcl_platform(platform) for the specified Tcl shell. KEYWORDS
operating system, cpu architecture, platform, architecture platform::shell 1.1.4 platform::shell(n)
