Re^4: Quote-like operators in a hash

Your reply got me thinking on the right track. for some reason, when I did,

print $key." : ".sqlExecute($value);

something went wrong and it returned 1's instead of the query result. It seems like Perl didn't like the concatenations. I re-did the print to,

print "\t\t".$key." : ";
print sqlExecute($value);
print "\n";

I'm not sure why that changed things, but it did. If anyone knows why, I would like to hear it. Thanks to all who helped. I wouldn't have figured it out with your help.

The difference is that print imparts a list context, but the dot operator creates a scalar context. Your `sqlExecute()` ends with "`return @result`". An array in a scalar context evaluates to the number of items in the array, but in a list context, it's all the elements of the array. Update: Here are a couple ways to get what you want without three lines: Use commas: `print "\t\t".$key." : ", sqlExecute($value), "\n";` Interpolate an anonymous array reference: `print "\t\t$key : @{[ sqlExecute($value) ]}\n";` The first is better for print, but the second can be useful in other places where you want to interpolate a function call.

So, in other words, the root answer is the same as for the previous question at the gates today: Concatenate printing a string and array Wow. Co-incidence? I think not - there's something afoot in 2009. I think we should expect many more arrays being concatenated with strings before the year is out... -- use JAPH; print JAPH::asString();	[reply]
