Question

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);
