这篇文章主要介绍了t-sql使用truncate and delete清空表数据的两种方法，大家参考使用

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。
