此脚本可以检索当前数据库中所有表的索引,返回一个查询结果集。
使用sp_helpindex存储过程
- 每次只能查询一个表
查询sysindexes表
- 这种方法的问题是,您需要编写复杂的查询
使用sp_msforeachtable
- sp_msforeachtable“ sp_helpindex'?'”
- 这种方法的问题在于,返回N个结果集,而且无法确定这个索引属于哪个表
为了简化整个数据库中所有表的索引信息的收集,只需对sp_helpindex存储过程进行简单的调整即可检索所有表的索引信息。因此,现在不必一次创建一个表,现在可以一次创建一个数据库。
看大神如何修改的sp_helpindex ,附链接
