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

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。
