我正试图通过<代码>ConnectODBC(%dings ,@jointionString);h abd 然后阵列
在这项职能中,我装上了my (%dings ,@jointionString) = @_;
。
for hash i get the right values but for print $connectionString[0] . ".
";
页: 1 在分类中使用未初始价值[0] ()
为什么?

为什么?
Since you are assigning to a list/hash, the first argument absorbs it all.
my %h1 = ( key => value );
my @a1 = (1, 2 );
my ( @a2, %h2 ) = ( @a1, %h1 );
# @a2 now contains (1,2,key,value) and %h2 is undefined.
为了获得你想要的东西,你应该通过提及。
ConnectODBC( \%settings , @connectionString);
sub ConnectODBC {
my ( $setting_ref, $connection_ref ) = @_;
my %settings = %$setting_ref;
my @connectionString = @$connection_ref;
}
我应该指出,在非常规提法中添加斜体和阵列可能没有必要。 你可以直接从参考中获取环境。 http://www.ohchr.org。
