What to do with 1.5 million records...
So my company just bought another company and they send me a flat text file
with 1.5 million records of customer name/orders/transactions etc - all in one huge txt file. Just for fun... I imported this into Access 2007 and you can view the single table, can't do anything with it, a simple parameter search on one customer name locks up the server, Access not responding, white screen blah, blah blah... I tired to split the table during import with the wizard to create the 6 or so tables I would like to have - but it kept bombing out. When I tried a small sample I see I get prompts for nulls fields and am asked to "leave as is?" a lot, so I guess when I tried to import the complete file that is where it is hanging up. Don't feel like cleaning 1.5M records today. Do I set this up on a SQL backend? If so, do I create the SQL db first then import the text file into SQL OR do I import the text file into Access and use the db splitter to create the SQL side? Is there a way in SQL to split into seperate tables? here are the fields - (tab delimited in file, i used comma here for ease): Acct Num, Cust Name, Address1, City, State, Zip, Service Call Date, Item, Qty, Amt, Pmt Date, Service Tech, Ins Name , Ins Paid, Balance Basically I see about 20 rows per customer name, each with a different Pmt Date (they pay on the accounts), looking for a ledger type report to run based on Customer name that will show all payment dates and current balance due. example 48714 Smith, Mary 123 Main Boston MA 02134 02012010 937821a 1 2,500 02012010 Bob-11 2,000 48714 Smith, Mary 123 Main Boston MA 02134 02012010 937821a 1 500 03012010 Bob-11 1,500 The intent is to use this data as read only, no new transactions will be posted, will just need to view previous balances for customers. Open to any and all ideas on this one... |
