I am trying to create a Database check for all versions of oracle(11g,12c,19c) to check the credentials set on a user using dba_credentials.(something like a metric extension)
But dba_credentials is only available in Oracle 12c.
Is there any view in 11g i can use for this purpose using a 'case' in sql depending on the version?
Credentials as a separate type of object didn't exist in 11g. You set credentials as part of the dbms_scheduler package. If you want to view those credentials, you can query the dba_scheduler_credentials data dictionary table. Depending on what you're actually trying to accomplish, you may need to query that table in later versions as well since not everyone migrating to 12c will have switched over to the new way of managing credentials.

In mongodb or firebase I can create {title:"sothigs, content:"somthing"} then I can create other object with only title for example {title:"second title"} or I even can create object with new values that i never defined before.
Is it possible to do with django sql databases?
If you are using PostgreSQL as your DB, then you can use JSONField in Django. Otherwise, check out more of the vendor-specific fields available in Django. This will lock you in to whichever database you end up using, however, PostgreSQL is a very good multi-purpose relational DB so I highly recommend using it.
While trying to benchmark Oracle's Database Inmemory, we were looking for publicly available benchmarking data set and tools. The CH-benCHmark suited our requirement exactly, but it has HANA Column Store Dialect as part of the source files.
So, our requirement is to convert these HANA Column Store dialect SQLs to Oracle 12c SQLs. Google search returned the conversion from Oracle to Hana dialect not the reverse.
Has anyone came across this requirement? Is there a simple/direct way to do the conversion?
Any pointers will be much helpful.
Yes I have done this exercise! there's no direct way from HANA Dialect to Oracle Dialect, But you can make use of ORACLE_LOADER and it's semantics to effectively create Oracle Dialect! Only problem you may face would be the flow, where HANA's flow is totally different from Oracle's schema creation flow.
For example:
you can easily use LOAD FROM FILE... syntax in HANA, But you need an externally organized table in case of Oracle.
Hi i am using SQL Server 2012. i would like to view the system objects code/definition. can we view the system objects definition/code in SQL Server any version ?
wanted to know when i execute this query SELECT MONTH(18/200), MONTH(200/18) i am getting output 1 for both just want to know internal code what is going on and how it is giving output 1 for MONTH(200/18) ? to understand this looking for MONTH() function code.
Use INFORMATION_SCHEMA
An information schema view is one of several methods SQL Server
provides for obtaining metadata.
Information schema views provide an
internal, system table-independent view of the SQL Server metadata.
Information schema views enable applications to work correctly
although significant changes have been made to the underlying system
tables.
The information schema views included in SQL Server comply
with the ISO standard definition for the INFORMATION_SCHEMA.
answer to SELECT MONTH(18/200), MONTH(200/18) is any integer to the MONTH() interprets 0 as January 1, 1900. that's whey it is returning 1 1 as output.
Ok so I have a little problem...
In my project we have a Oracle SQL Server. In the database I have access to some of an other users tables:
Tables:
|-bla
|-bla
Users:
|-otherUser (let's just call him that)
|-Tables:
|-aTable
In Oracle, to access the aTable table I use SELECT * FROM otherUser.aTable
Now, we also have a MS SQL CE database to which I sync the data from the OracleDB using the MS Sync f/w. And in the CE db - after sync - I get a table otherUser.aTable. This sounds good, so even though the CE doesn't have the User concept it just adds the same table.
BUT the problem is that when calling the same SQL query on CE as on Oracle I get a The table name is not valid error. Instead if I want to get the content of the table, the two ways that I have found to work is surrounding the otherUser.aTable with either [] or "".
However neither of them seem to work with Oracle. The [] seem to be an illegal name, and the "" seem to search for a table called just that (not an other user).
So why don't I just use the one way on Oracle and the other on CE? well I also use NHibernate as a ORM and it kind of needs the same table name for both the databases...
Is there a third way to encapsulate the table name that works with users in Oracle and just works in CE? or do you have any other ways to fix this issue?
I have no experience with MS SQL, but it seems like a problem that might be solved with synonyms on Oracle side.
Try to create synonym "otherUser.aTable" for otherUser.aTable in Oracle.
Our app uses migratordotnet to modify the backing SQL Server 2005 database. This works great 99% of the time but we are running into an issue. We have a client that is using and Active Directory group for sql server login and when new tables are added it creates them as Domain\login.table_name. What permissions are needed to be given to the AD group to add the tables as dbo.table_name? This does not happen in with all of our clients with similar configurations so I must be missing something.
Make sure that the default schema for that login / group is set to dbo.
Can you set the default schema for a group? I was unable to do that using the management studio. I am trying a solution now that specifies the schema "dbo.table_name"
