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。 原文链接：https://www.f2er.com/mssql/63339.html
