The differences of truncate and delete in SQL vary with the database. It is different in Oracle, MySQL, MSSQL and others.
Truncate and delete in SQL both delete the data in the table, but they manage deleting these through the different functions.
Truncate completely removes the meta information and table’s data. You are just like returning the original table. On the other hand, you can remove the rows through the delete in SQL. Moreover, you can also remove a specified condition depending on the WHERE condition. This delete function also work on resetting the auto-incrementing counter.
Furthermore, there are also differences in the Truncate and delete in SQL run. The Truncate runs speedily than the delete. Delete eliminates rows manually or one by one, while truncate removes the entire row at a time. The delete in SQL removes the rows while creating the removal’s transaction log. In this way, you can still restore and undo the activity if needed. If you truncate, it means that you completely remove the data. You can never retrieve it back if you need the data again.
