I am storing some database column names in hash and based on the parameter passed with perl script i need to selecr the particular hash

Example:

test.pl A, the hash to be selected is @COL_CHECK_A and if its B, we need to select @COL_CHECK_B

my @hash;
my @field;
my @COL_CHECK_A = qw( NAME CITY STATE );
my @COL_CHECK_B = qw( NAME CITY STATE COUNTY );
my @COL_CHECK_C = qw( NAME AGE STATE COUNTY );
my @COL_CHECK_D = qw( NAME AGE CITY STATE COUNTY );
my @COL_CHECK_E = qw( NAME AGE DESIGNATION CITY STATE COUNTY );

foreach my $key (@COL_CHECK_$ARGV[0]) {
push( @field, $hash{$key} );
}
[download]

Any suggestions please.
