how to obtain a list of schemas in intersystems cache?

问题

I'm connecting to a Caché database using the ODBC driver, and I want to do a query to obtain a list of schemas. In Microsoft SQL Server I can use a query like this:

SELECT * FROM INFORMATION_SCHEMA.SCHEMATA

How can I do this in Caché? I'm also using ADO.NET schema collections, but the schemas don't seem to be available there.

回答1:

The schema %dictionary has the tables you are looking for. You could select from %dictionary.compiledclass
