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

  • A+
所属分类:MSSQLSERVER


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。
