如果可以在DB2中使用，请任何人帮助我。

DB2fori-series实现了其目录，您可以使用SQL查询尽可能多的视图和表，以获得所需的答案

不同的Db2服务器平台以不同的模式实现它们的目录。 z/OS上的Db2在SYSIBM模式中实现其目录表。 Linux/UnixWindows上的Db2在SYSCAT模式中实现其目录视图（但在SYSIBM模式中也有一些视图的基础表）

由于有许多这样的视图（例如），在此处复制产品文档中的许多文档页面是不明智的，因此请使用该页面作为搜索的开始。您应该了解i系列的确切版本，然后通过“更改产品版本”菜单在页面上选择该版本。有时不同的版本具有不同的目录视图，因此请选择与服务器匹配的版本。
