Join Rows in many Tables

Hi everybody,

I have read many CSV-Files with the format "name", "symbol"(key), "value". The CSV-Files are created every 30 minutes with a time stamp in the filename
The fields are for example:
"Firma 1","F1","84"
"Firma 2","F2", "67"
"Firma 3...."

I have circa 30 CSV-Files of this type and I want following:
I need a Operation, that I have for every "symbol" the chronological sequence in one table:
Table name: "<symbol>",
with the values:
"2013-11-18 07:00PM", "84"
"2013-11-18 07:300PM", "85"


I hope yxou understand my problem, because I dont speak english very well.

Best regards,
Diego
