I have repeat values, I read this but now I don't know how to proceed..
If your hash could have repeated values, the methods above will only find one of the associated keys. This may or may not worry you. If it does worry you, you can always reverse the hash into a hash of arrays instead:
while (($key, $value) = each %by_key) {
push @{$key_list_by_value{$value}}, $key;
}
I am confused enough just using hash, hash of arrays, can I put it back into a hash somehow?, reason I want the hash is to input the data into a table in sql, using sql abstract, which looks like it should work for my purpose to store this data in a db, maybe I could somehow fix my data file to be correct by changing the way information is logged so that its numbers then names by using regexes to move the labels I have around.

well let me clarify a bit here.
My hash is backwards, data file example is below.
Database has columns for Date,Login,SearchLoad,etc,
Date column is a date/time
login real
searchload real
when I read file into hash I get timevalue->columnname, I want the reverse which would be columname->timevalue.
In order to fix my data file, I want to add a label Date to the first value which is a timestamp for each record throughout the file, then I want to read the file into a hash so I can input it into the database which is currently empty and only contains the columns I want to use for the table.
The sql for the table creation is in the bottom of this comment.
