inserting 3 million rows

[banaax]

I have a mysql database with dreamhost that I am putting over 3 million rows into (all in one table, each row has 6 doubles). I'm doing it using netbeans, my code has a loop that executes an insert query for each entry. I've got about 500,000 in so far after about 24 hours, is there a better (quicker) way to fill a table that is this large?

Instead of running each query to the database at a time, I instead write the contents that I want to write to the database to a buffer, then write that buffer at the end to a file. Then I 'LOAD DATA INFILE' the database all at once, which reduces the time significantly. Also be sure to free up your resources in your script as you don't need them.

The best way is with a statement like this:

load data infile 'path/to/infile/filename.txt' into table TableName(column1,column2...);

If the input file is tab delimited, there should be no major problems.
Depending on the server being used, 3 million rows could take a few minutes to load. Also leave the indexing until after the data is loaded.
