The only way to query this sort of thing at runtime is to read the table and calculate what you need.在运行时查询此类事情的唯一方法是读取表并计算您需要的内容。 It's not going to be that pleasant.它不会那么愉快。

The best way to provide this sort of information though is to use a DB Analysis.不过，提供此类信息的最佳方法是使用 DB 分析。 From a proenv session on the database server:从数据库服务器上的 proenv 会话：

proutil [dbname] -C dbanalys > mydb.dbana proutil [dbname] -C dbanalys > mydb.dbana

The output of this contains all the info that you need.此输出包含您需要的所有信息。 You should be careful of running this during busy times as it will have a performance impact.您应该小心在繁忙时间运行它，因为它会影响性能。

Documentation on the command is available here: https://documentation.progress.com/output/ua/OpenEdge_latest/index.html#page/dmadm%2Fproutil-dbanalys-qualifier.html%23wwID0EFCKY该命令的文档可在此处获得： https : //documentation.progress.com/output/ua/OpenEdge_latest/index.html#page/dmadm%2Fproutil-dbanalys-qualifier.html%23wwID0EFCKY

This also includes details on the -csoutput option that produces the files in a nicely segregated text file format which may make parsing the info you want easier.这还包括有关 -csoutput 选项的详细信息，该选项以很好地隔离的文本文件格式生成文件，这可能会使解析您想要的信息更容易。
