Re: An Array without an Index

Hello Toppo, and welcome to the Monastery!

Two quick observations:

```
@row=();
while (my @row = $stm->fetchrow_array){
[download]
```
The my in the while loop creates a new @row variable each time through the loop. ~~This is almost certainly not what you wanted.~~ Update: You don’t want both! See the comment by Anonymous Monk, below.
the array @results don't appear to have an index

I don’t know what you’re trying to say here, but be assured that every element in every array has an index! See e.g. perldata.

I think more information is required before the monks can help you. Please provide a minimal but complete, working script that demonstrates the problem, along with sample input, and a description of the desired output.

HTH,

He said the program runs under strict and warnings. But the `@row = ()` and the `my @row` in the `while` loop are two distinct variables. Since he is not using the first `@row`, it does not seem to be the cause of his problems. CountZero A program should be light and agile, its subroutines connected like a string of pearls.

He said the program runs under strict and warnings ... it does not seem to be the cause of his problems. Of course, this is just a symptom ( not coping with scoping ) ; the cause is indeterminable.	[reply]
