Re: Referencing a HoA

You want @$aref = @$tables{$table_name}; instead of

@$aref = $tables{$table_name};
[download]

As for why $aref = $tables{$table_name} doesn't work, it's because $aref is just a scalar value, so you're just changing the value of the lexical $aref, not @fields.

Update: See replies -- I forgot the curlies around $tables{$table_name}.

That yields the following message: `Global symbol "$tables" requires explicit package name at noname.pl li +ne 18. Execution of noname.pl aborted due to compilation errors.` [download] Though I thought it was the equivalent of what BrowserUk posted: `@$aref = @{ $tables{$table_name} };` [download] which does work. I guess I need to study references more closely. :(	[reply] [d/l] [select]
