SQL Server 查找索引定义

Question

SQL Server 查找索引定义 我的任务是将一组表架构、内容和表对象迁移到 Azure SQLdb。我遇到了触发器和索引的问题。他们没有被复制。触发器很容易从 sys.modules 表中获取，但没有索引。

Answer 1

我没有运气在这里或互联网上找到任何东西，所以我写了这个。我希望这对某人有所帮助。

The follow has the following defaults that may not suite your needs.
PRIMARY KEY CLUSTERED
STATISTICS_NORECOMPUTE = OFF
SORT_IN_TEMPDB = OFF        I leave this on Since my TempDB has the room,
                            bandwidth, and it's own IO channel.
                            It's up to you though.
