I am new to SQL 2000 and scratching my head...I am importing text files to SQL 2000 tables. How should I define the primary key in a table if the text file is :
Example 'customer invoice file'
column 1-Customer Bus Unit (Char 3)
column 2-Batch number (Char 6)
column 3-Document type (Char 1)
column 4-Invoice number (char 15)
column 5-Invoice dollar (Money)
column 6 - due date (date)
column 7 - customer name (char 35)
column 8 - customer address (char 50)
The primary key of this file is column1 + column 2 + coumn 3 + column 4. That concatnation of 4 fields make each record unique.
Should I define all 4 feilds as the primary key field? Thank you, Yanoroo
I'm glad it worked for you....It's always better to know that you're working with clean data...
TRUST NO ONE bearing Excel spreadsheets...(or other data sources outside your environment)..
Better still require data files with header and/or trailers...and if you can only get one...demand a trailer...with record counts and possible the sum of int/decimal columns...
