Delete vs Truncate in MySQL and MS SQL Server

-
Delete vs Truncate in MySQL and MS SQL Server DELETE DELETE is a DML Command. DELETE statement is executed using a row lock, each row in the table is locked for deletion. We can specify filters in where clause It deletes specified data if where condition exists. Delete activates a trigger because the operation are logged individually. Slower than truncate because, it keeps logs. Rollback is possible. TRUNCATE TRUNCATE is a DDL command. TRUNCATE TABLE always locks the table and page but not each row. Cannot use Where Condition. It Removes all the data. TRUNCATE TABLE cannot activate a trigger because the operation does not log individual row deletions. Faster in performance wise, because it doesn't keep any logs. Rollback is possible.

It stands as the most widely employed database engine globally, integral to the operating systems of virtually all mobile phones and the majority of computers. Additionally, it is packaged within numerous everyday applications. The SQLite file format boasts stability, cross-platform compatibility, and backward compatibility. Developers commit to maintaining this stability until the year 2050. SQLite database files serve as prevalent containers for the exchange of rich content across systems and as a long-term archival format for data . The active usage of SQLite databases exceeds a staggering 1 trillion (1e12) instances [5].
