Public synonyms in a pluggable database deletion

Similar Questions

• Synonym does public get used by the database engine in the schema of the owner?

  I have database public synonym 'P' and "S.P" table (in the "S" pattern).
  If my article references select array/object 'P' (without prefix-schema for the table), then there is no reference to the table ("S.P') or that it references a synonym ("P")?
  I understand that if my select query is executed in the session/connection made with schema/user "S", then the database engine does not at all synonymous, it will immediately table 'S.P. Is this right?
  Can you just confirm my understanding, maybe I'm wrong.
  
  (Oracle 10g, Windows OS)

  Fix. There is a certain order regarding name resolution.

  If I remember correctly then it searches first for the current schema objects (tables, views, procedures, etc.), then for private synonyms, then public synonyms.

  I get a bit more complex if you have a schema that is also the name of a package for example.

• Privileging the public synonym over schema object

  Hello

  I have a request.

  I logged in a scheme called "SCOTT."

  I have a table called 'EMP '.

  Now, I created a view called "EMP_D" with the addition of more of a few columns.

  Now I create a public synonym 'EMP' pointing to display "EMP_D".

  Now, I'm pulled the query in the schema "SCOTT."

  Select * from EMP

  I want that data to the EMP_D view.

  How to get there?

  Thanks in advance

  My question is

  is it possible to prioritize the resulting public synonym of the same schema?

  Its only for a solution.

  This is called "name resolution" and is documented here: http://docs.oracle.com/cd/B28359_01/server.111/b28310/general008.htm#ADMIN11561

  1 oracle database attempts to qualify the first piece of the name referenced in the SQL statement. For example, in scott.emp , scott is the first piece. If there is only one piece, the piece is considered to be the first piece.

  1. In the current schema, the database looking for an object whose name matches the first part of the name of the object. If it does not find such an object, it continues with step b.
  2. The database looking for a public synonym that matches the first part of the name. If it does not find one, it continues with stepc.
  3. ...
     

  So if you have a schema object with the same name as a public synonym, oracle will always use first the schema object.

  Your only chance would be to rename the schema object or use another schema.

• 2 various CARS: same Public Synonyms on the same 2 diagrams - any interaction?

  I'm having a senior moment.

  I have not worked with public synonyms that often, so I just want to make sure I got it right.

  If you have two instances: Instance1 and Instance2

  They both live on the same Oracle RAC cluster.

  Intance1 and Instance2 have a schema named FRED.  Both of them have a synonym Public THISTABLE for FRED. THISTABLE

  Now, I want to just make sure that the public synonyms do NOT connect between two different, although instances on the same RAC system, right?

  Someone on Instance2 inserting in fred.thistable is ONLY for this instance, instance1 do not affect all, correct?

  You would have to do something like this, essentially a database link between them and could have a public link THISTABLE on Instance2 pointing to FRED. THISTABLE on Instance1... but simply want to make sure that I understand that only a dblink between two patterns on the two bodies will... allow traffic/access between the two bodies and public synonyms on their own will not cross the instance gap, even with two instances on the same cluster.

  Once again, senior moment here and just want to make sure I have it directly.

  Thanks in advance,

  Cayenne

  This case I put in place the same pattern of FRED and the same FRED table name. TABLEAUCETTE on the database instance instsqa... There is no link between the two with this public synonym on instdev. The only way you could link the two instances and schemas for the table would be by a... correct database link?

  Yes. You got right.

  Take CARS out of it.  It's the same as if you had 2 databases one-off names instdev and instqa.

• Public synonym in Expdp

  Oracle: 11.2.0

  OS: Windows

  Is it possible to export the public synonym with the help of the utility expdp?

  Otherwise, what is the reason behind this?

  Thank you

  AKPT

  Hello

  public synonyms can be extracted on their own by using:

  expdp / full = include = PUBLIC_SYNONYM/SYNONYM

  Full database export then by default includes

  Kind regards

• public synonyms

  Hello

• How to check what are the objects using this public synonym?

  Hi Experts
  
  Currently, I have a public synonym, WORK that is created for WORK table in the schema of the BRAND: "synonym PUBLIC EMPLOYMENT BRAND. JOB. "

  You will have no SQL in the audit trail, because you have not configured the parameter correctly. You must audit_trail = db, extended to get the SQL code.

  2. the date and time on which the statetement GRANT was pulled

  You will have anything unless you have enabled auditing for the instruction given with
  Check create public synonym;

  How can we find it?

  You can't until you configure the audit in an appropriate manner.

• Public synonym for DBA only?

  Is it true that only DBA can create public synonyms?
  Or is it better for a DBA to publish it rather than other users? Is it because it is the responsibility of the DBA or what? Thank you.

  Everyone can 'CREATE a PUBLIC SYNONYM':
  http://download.Oracle.com/docs/CD/E11882_01/server.112/e17118/statements_9013.htm#i2155015

  And it should be someone who knows what is happening in all of the database. Sometimes it's s/n, but above all, there is a technical project manager who knows the need for application much better.

• PUBLIC SYNONYM - strange behavior

  I just organized a test on SQL queries for my students.
  
  It is based on four tables in a schema, and I created public synonyms for each table and read privilege to the PUBLIC, for example
  
  Staff CREATE a PUBLIC SYNONYM FOR testuser.staff
  GRANT SELECT ON testuser.staff to PUBLIC
  
  All the 150 + of my students have exactly the same roles and privileges, and yet two could not access the table of personnel without to refer to him as testuser.staff. They were able to access as provided for in the past.
  
  Has anyone encountered this before? I can't imagine that it's something to do with 60 students hit the synonym even at the same time, but I wonder.

  Hello

  Both users apparently have their own tables (views, synonyms, or other objects) called the STAFF.

  What kind of results do get when they use the unqualified name, like this

  SELECT  last_name
  FROM    staff;
  

  ? "If they get"ORA-00904"'Name': invalid identifier", it might be because their own staffing table is not a column named LAST_NAME.

  A name to your own schema takes precedence over a PUBLIC synonym. It makes sense: you don't want all your own queries on your own STAFFING table to stop just because someone used the same name for a public synonym.

  Concerning
  VIDS

  Hi vidusnat!

  It is onlinedocumentation to Oracle:
  >
  Privileges required to create views

  To create a view, you must meet the following requirements:

  You must have been granted one of the following system privileges, either explicitly, or by a role:
  o CREATE The VIEW system privilege (to create views in your schema)
  o The CREATE ANY VIEW system privilege (to create a view of another user schema)
  You must explicitly obtained one of the following privileges:
  o the SELECT, INSERT, UPDATE, or DELETE object privileges on all objects in the view's underlying base
  o SELECT it ANY TABLE, INSERT a WHOLE TABLE, UPDATE ANY TABLE or DELETE ANY TABLE access privileges

  In addition, in order to grant access to your display of other users, you must have privileges to object to the base with the OPTION GIVING clause objects or system privileges with ADMIN OPTION clause. If you do not, users cannot access your view.

  I hope that this will bring a little light in the darkness!

• How Public synonym works.

  When a search is done in data in a table via a public synonym, not the associated table, the index is used or not. I think he did, but I want to be sure, can someone also confirms this.
  
  Thank you

  Hello

  Yes, of course public synonyms use underlying indices. Its very simple test.

  You cannot connect to a PDB file through a registration of the listener static like this, because there is just no SID not named MYPDB1. You must register the services dynamically. In the root.

• 4.1EA2 - overview of Code does not take into account public synonyms

  Hello there,

  I think that the completion of the tablenames in the modified spreadsheet of sort it ignores now public synonyms.

  When I type

  Select * from user_

  and press CTRL-space I get SYS.user_tables SYS.user_tab_columns etc. It's a little embarrassing.

  Now the question is, can I code insight also offer public synonyms? And if not can I at least get the usernames lowercase?

  Kind regards

  dhalek

  Run

  the hidden value of param querySynonyms = true

  command to activate the thesaurus in code insight. This has changed due to the execution of view poor synonyms dictionary in 12 c with insight omitting guest more important objects tables, views and pl/sql modules.

  Also, make sure that

  Preferences-> completion Insight-> change case as long as you type = None

  then the object names would be in the same case that they extracted from the dictionary (upper case).

• Reached the maximum number of pluggable databases

  Hello

  I seem to have a problem creating a pluggable database.  I'm getting ORA-65010: maximum number of pluggable databases created.  What seems strange to me, is that I have only a plug-in database in the container.  This doesn't seem to be a common theoretical problem? maximum number is 252.? I've seen a few different numbers while rummaging through the internet.  I can't seem to find documentation about this limit or why that would trigger my max at 1.  I wonder if this can a hardware limitation, but after going through the error logs and love it, I can't find any problems with the initial installation.

  A little info, installation was complete installation + CBD + PDB.  Class Server, standard installation and I can connect both the container and the snap-in internal database and connection to the outside.  Most of the time I think its configured correctly.  I have a feeling that I missed something along the way, but I'm struggling to find an explanation for this.  The documentation is fine as a response, just needing a point in the right direction.

  Thank you.

  Hello

  For Enterprise edition of Oracle database, the limit is 252 connectable to databases. If you are using an Oracle database Standard edition, you can create a single snap-in database.

  Thank you
