复制代码 代码如下:
TRUNCATE TABLE (Transact-SQL)
Removes all rows from a table without logging the individual row deletions.
TRUNCATE TABLE is similar to the DELETE statement with no WHERE clause;
however, TRUNCATE TABLE is faster and uses fewer system and transaction log resources.
两者的区别在于Truncate快，而且释放日志所占资源，不记录由于删除行的影响所产生的日志。
