Recently one of my code gave the err message
Can't use string ("query") as an ARRAY ref while "strict refs" in use at ...
I have checked the file and the point where it was failing was when the file had the query as "query" The file has multiple number of fields seperated by a fixed delimiter so the point where it failed was in the line 
query us 123  --> this line it failed
queue ca 456

A snippet of the code which i used is as follows 

if ($query eq $hash{'query'}){
        push @{$hash{$query}},{'domain' => $domain ,'count' => $count}
+;
        $tot_count += $count;
}
else{
        my $qid = $hash{'query'};
        .... some operations

        %hash=();
        $hash{'query'}= $query;
        push @{$hash{$query}},{'domain' => $domain ,'count' => $count}
+;
        $tot_count = $count;
}

I have fixed the code and changed the hash structure and it works fine now.
But i do not under stand why the error would be thrown if we have to assign $hash{'query'} = "query";
Can the knowledgable monks explain me what does the error mean and why it failed.

Edit by GrandFather - replaced pre tags with code tags, to prevent distortion of site layout and allow code extraction.
