如何在Sybase中查找包含字符串的所有db对象

Question

有时我需要在DB中找到一些字符串，通常它只是主机名或IP地址。

是否有任何脚本在我有权访问的所有Sybase数据库对象（或至少在所有表中）中找到字符串。

Answer 1

对sysobjects + cursor + EXECUTE的查询有效。有点儿。

sp__map_object 'SELECT * FROM %O where name like "bar%"', 'foo_%'

代码中存在很多错误/问题/担忧，我不愿意发布它，但我对Sybase患者有一定的同情。

Rob Verschoor有一堆很好的存储过程 http://www.sypron.nl/new_ssp_dwn.html

我当然不知道。您也许可以滚动查询系统表的过程以获取对象列表，然后让光标通过并查询这些对象以查找给定的搜索条件。
