We have an existing database link in an Oracle database that links to data

  • 0

We have an existing database link in an Oracle database that links to data in a Sql Server database. Now, a 2nd Oracle database needs to use that same data. Due to security setup, the 2nd Oracle database cannot “see” the Sql Server database, but it can see the 1st Oracle database.

If we create a database link in the 2nd Oracle database that points to the 1st Oracle database, will we be able to query data from the Sql Server database in the 2nd Oracle database by going through 2 database links? Would the query syntax look like this:

SELECT * FROM myTable@2ndLink@1stLink

Has anyone done something like this before?

    I’m not sure this synthax would work (although it would be interesting to test it I can not do it right now). However, even if it doesn’t work, you can still create a view in Database 1 that points to a table in your SQL Server Database. From Database 2, you could then query:

    SELECT * FROM myView@db1

    That would point to the correct table.
