What is the fastest way to populate a SQLite database from a DataTable in

  • 0

What is the fastest way to populate a SQLite database from a DataTable in C# .net 2.

Currently I am building insert statments for each row in the table. I have tried a dataadaptor but the speed didn’t seem to be any faster. It currently takes 5 min to loop through 20,000 rows and write them to the database.
Any sugestions?

solution:

I found that surounding blocks of insert statments with BEGIN…COMMIT worked for me with a remarkable speed improvement:

BEGIN;
INSERT INTO friends (name1,name2) VALUES  ('john','smith');
INSERT INTO friends (name1,name2) VALUES  ('jane','doe');
COMMIT;

my insert statements were around 500 byte each, so I limited the number of statements to 100 per transaction.

    See this FAQ entry from the SQLite website:

    http://www.sqlite.org/faq.html#q19

    By default, each INSERT statement is its own transaction. But if you surround multiple INSERT statements with BEGIN…COMMIT then all the inserts are grouped into a single transaction. The time needed to commit the transaction is amortized over all the enclosed insert statements and so the time per insert statement is greatly reduced.
