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?

You are right.....it is an internal command that only works with SQLPlus.....shame though....

oracle has equivalent information_schema

Select * from all_tables

select * from all_views

Select * from all_tab_columns

Desc Table1 in Oracle will do this..

Desc --->Describe

Desc:

will give definations of each column's name
whether or not null values are allowed for each column
datatype of columns, etc
