The marathon run for importing Norwich LETS's msaccess-based database to LocalExchange's MySQL-based database has ended a while ago. It took almost 7-8 hours and pushed my SQL knowledge to its limits. Here's how I did it.
0. Open database in MSAccess and export all tables as CSV file.
1. Make a list of columns in each table and create identical tables in MySQL.
2. Import the tables from the CSV files into MySQL:
$ mysqlimport -u dbusername -p --local --fields-terminated-by=, --fields-enclosed-by='"' --lines-terminated-by='\r\n' norlets tablename.txt
