There are many ways to insert data a database using the command line. You can use datainsert, fastinsert, or insert. For best performance with large volumes of data, it is recommended to use datainsert or fastinsert.
As you are still experiencing performance issues, create a data file with every record in your dataset. Then, you can use this data file as input into the bulk insert functionality of your database to process the large dataset. Additionally, you can insert data with special characters such as double quotes with this file. Bulk insert provides performance gains by using the bulk insert utilities that are native to different database systems. For details about exporting data using bulk insert, see the following link:
