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
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).
