Microsoft office 365 homeComparing multiple rows insert vs single row insert with three data load methods The performance of 'extract, transform, load' (ETL) processes for large quantities of data can always be improved by objective testing and experiment with alternative techniques. Comparing multiple rows insert vs single row insert with three data load methods The performance of 'extract, transform, load' (ETL) processes for large quantities of data can always be improved by objective testing and experiment with alternative techniques. Then for each row you want to insert you will bind necessary values, execute statement and reset. With all that wrapped in transaction there's no way to make insertions any faster. Even if SQLite supported the multi-row insert syntax it would do exactly the same operations - bind values, insert row, reset, bind values, insert row, reset. Example rows = cursor.
