Re^4: Hash throws out duplicate values

What I'm trying to do is pull records from a database that has information about how an access point should be configured. I wanted to read that data into an array of hashes so that I could then step through each of the elements and repeat the commands I would type at the command prompt to configure them and automate the process. The reason for the use of $new_name and $old_name is so that during the automation process I can keep track of which variable I am using. When the database info is imported, the ap name is the new one it needs to be changed to. I run a different sub to query the ap for its old name, which happens to be the default name it boots up with. Then, to change its name, I issue the command 'config ap name <new> <old>' So, as I said, I thought an array of hashes would be the ticket, and that I would then just step through the array and duplicate all of my cli commands.

I am certainly not a DB guy, but I think you have the wrong type of query. I would think that fetching rows from the DB makes more sense. This row that you would get from the DB will be in a fixed order. Using hash slice, you can make a hash and push it onto an array. So maybe the first place to start is with these 11 fields. I couldn't figure out the DB names for all of these so, I just put x,y,z. If you could fill-in the second column below, that would be most helpful. `JP-AP1-1-RM_210, xxxxx Johanna Perrin, yyyyy wism3-1, zzzzz 10.137.139.2, wism4-1, 10.137.139.6, wism7-1, 10.137.139.10, JP, 149, not_configured` [download] The basic idea is to get a row from the DB, then make a %hash from that row (with the keys being x,y,z above) and then push a ref to that hash onto an array. You will wind up with a memory structure with same info as in the DB. The order of the records within the structure will not correlate to any kind of order within the DB (I guess you know that).
