I've created a stored procedure. I fetch cursor with huge amount of data(around 1L rows). After that I call another procedure in it to do all calculations related to needed data. I create temporary table and try to insert this calculated data in it. But it takes too long about 9.5 mins. I want to know how to insert bulk data by using least "INSERT" queries as 1L insert queries cause poorest performance. Can anyone help me??

You can use the following SQL statement for bulk insert:

INSERT INTO TABLE_A (A, B, C, D) VALUES
(1,1,1,1),
(2,2,2,2),
(3,3,3,3),
(4,4,4,4);

Your question is a bit vague but you can BULK load data into mysql using 

load data infile...

Check the following links:

If you need to process the data during the load it might be better to first bulk load the data into a temporary table then run some stored procedures against it which process and populate your main tables.

Hope this helps.

also you can insert record to in-memory table.after complete inserting to in-memory table following code for insert many rows from in-memory table.

INSERT INTO TABLE_A (A, B, C, D)
SELECT A,B,C,D FROM INMEMORY_TABLE

DELETE FROM INMEMORY_TABLE
