I'm building a set of SQL Server views that use OPENQUERY to run queries against an Oracle server.

I want to see the metadata of the query from Oracle's perspective.

Is there an equivalent to SQL Server's sp_help for Oracle that I could use?

you can use the two built in procedures which are used specifically for interrogating linked servers.

EXEC sp_tables_ex [OracleLinkedServerName] will get you started, but from there, you need to find a database/schema/table to really dig into:


EXECUTE sp_tables_ex
@table_server ='CPULinked',
@table_schema='BOOFILES',
@table_name = 'DOCTR'

EXECUTE sp_columns_ex
@table_server ='CPULinked',
@table_schema='BOOFILES',
@table_name = 'DOCTR',
@Column_Name ='DRTYPE'

Thanks for the tip!

Unfortunately, these queries returned empty result sets for me, though the server, schema and tables/views most certainly exist (and I can query them using OPENQUERY)

Actually what I was looking for was an equivalent to sp_help that I can run on Oracle. So something like:


select * from openquery(oracle, 'exec sp_help ''schema.table''')



replacing 'exec sp_help ''schema.table''' with whatever the equivalent is on Oracle.

ahh, sorry.
DESC or DESCRIBE TableName will get you some information, not sure how pretty it will be over a linked server, but that's what you want to try.

Alas, I don't think you can run DESC over OPENQUERY, since it is not a SQL command. I think you can only do that with the SQLPLUS command.

Could be wrong though!

Doesn't Oracle have metadata views like ALL_TABLES, ALL_TAB_COLUMNS and ALL_USER_TABLES? Can you query those?
