Hi List,
I need to import data from a large Excel spreadsheet into a PostgreSQL
table. I have a program that uses ODBC to connect to Excel and extract data
using SQL queries. The program then inserts the data into a PostgreSQL
table.
The challenge with this particular spreadsheet is that it is arrayed thus:
Model No 1 Product Code 15
Serial No 1 No on Hand
Serial No 2 No on Hand
Serial No 3 No on Hand
Model No 4 Product Code 9
Serial No 12 No on Hand
Model No 5 Product Code 27
Serial No 6 No on Hand
Serial No 14 No on Hand
etc.
I need the data in PostgreSQL arrayed thus
Model No 1 Product Code 15 Serial No 1 No on Hand
Model No 1 Product Code 15 Serial No 2 No on Hand
Model No 1 Product Code 15 Serial No 3 No on Hand
Model No 4 Product Code 9 Serial No 12 No on Hand
Model No 5 Product Code 27 Serial No 6 No on Hand
Model No 5 Product Code 27 Serial No 14 No on Hand
I can import the data procedurely using plpgsql to match the individual rows
to the master for each row (import the raw data into a buffer table in
PostgreSQL and then looping through the rows in the buffer table and
checking to see when the Model No changes).
I'm wondering if there is a more elegant way to do this using straight sql
from Excel?
Thanks for your help/suggestions!
George
