t-sql清空表数据的两种方式示例(truncate and delete)

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。
