If you''re using Paradox and PostgreSQL, Postgres functions are your 
best friend. For example, you can send a csv file path in a parameter to 
a function, then build the import statement into a temp table and 
execute it in the function. Then you can do whatever you want with the 
data in the table, update or insert into other table(s) ar  anything 
else you can think of. It will be fast because the query is one 
transaction. Maybe set your commits at the beginning of the query to 
every 1000 rows.

My Appliance ServiceManager application only ever passed one single 
statement to PostgreSQL.

"SELECT * FROM "function name" (param1, param2, param3 ... paramN);"

All parameters were "char" and were converted in the function. If the 
function returned data, I would include a priv paradox table in the 
execute sql command, if an in-memory tcursor ditto. So the BDE only ever 
had to parse one command. I had a library method that parsed a string 
and checked for quotes slashes etc and added escapes.

No sql injection here, folks.

Also remember that triggers and views are your equal 2nd best friends.

I could rave on about the benefits of transaction security, consistency, 
referential integrity that works, scheduled execution of tasks etc etc 
but you probably know all that already.
