In the "batch operation of Typed Dataset" section 30th, the instructor suggested to manually open the database connection and then Perform Batch insertion when inserting data in batches. The effect is as follows: manual connection insertion saves as much time as 20 times (45 seconds and 2 seconds) than manual connection insertion) (Instructor video code) I have read some questions, because we know that it takes a lot of time to run the program
