TRUNCATE is faster than DELETE in SQL Server because: No Row-by-Row Deletion: DELETE removes rows one by one and logs each row deletion, which takes more time. On the other hand, TRUNCATE deallocates entire data pages, removing all rows in one operation without logging each row individually. Minimal Logging: TRUNCATE is a minimally logged operation, whereas DELETE generates a lot of log data for each deleted row, slowing down performance. No Triggers or Foreign Key Checks: TRUNCATE does not activate triggers or enforce foreign key constraints, unlike DELETE. Here is my number Call 073-1485-0321. read less
