HowTo: Comparison CVS checkout with Database Schema [functions, procedures]

Dear Team,
Requirement: Compare & update the latest scripts from CVS/repository directly into Oracle Schema, for stored functions, packages, stored procedures, views etc respectively.
Currently using Oracle 9/10 with SQL Developer 2.1 supports with CVS. However unable to compare the schema with the CVS checkout scripts. Does this facility is provided? If not any other alternative (exclusidng the manual comparison of the scripts), respectively.
Thank you in advance!

This question is off-topic in "Database - General."
As it relates only to SQL*Developer post it there.

  • Problem with database schema objects in the entity object wizard

    Hi All,
    When creating a new entity object, I am facing a problem with database schema objects in the entity object wizard, database schema objects (check boxes for tables,synonyms...) are disabled. Actually I am using a synonym but I am not able to select the synonym check box.
    Can any of you folks tell me how to enable the database schema objects (check boxes for tables,synonyms...).
    Thanks in Advance.

    Make sure your using rite version of jdeveloper..
    Make sure your using apps schema and check whether your able perform DML operations in the schema vis sql developer.

  • Howto initialize JPA attribute with database sysdate?

    Hi,
    we have the problem that we are required to initialize a "created" attribute of our TopLink JPA POJOs with the current SYSDATE of the Database (as there is a time difference between Application Server and Database Server). For this reason, we cannot simply set the value in the constructor of the Java object.
    Is there any approach to solve this issue?
    regards,
    hans

    In general be careful in doing this if you are concerned with performance, as accessing the database for the current time can be expensive. Normally the Application Server time should be sufficient.
    You have a few options for accessing the database time.
    - You could query the SYSDATE from the database in your application code when you create your object.
    - You could use a TopLink or JPA insert event to query the SYSDATE from the database to populate your object.
    - If you are using TopLink you could use the ReturningPolicy to access the "created" field from the database on insert, and assign the field in the database table using a trigger. The ReturningPolicy is only available in TopLink, not TopLink Essentials.

  • How to create a database schema

    could any one help me with database schema I need create one
    thanks!

    I am told that I am connected to an idle instance...not sure what this means It means the database is down. Because you connected AS SYSDBA your connection did not fail; if you had attempted to connect as any other user you would have got the ORA-01034 immediately. So all you need to do is startup the database:
    SQL>  startupBy the way it is considered bad form to resurrect old threads, especially when (as in this case) your issue is not really germane to the original post.
    Also, if you're going to tool around in a database as SYSDBA you really ought to familiarize yourself with the documentation: start with the Concepts Guide and the the two-day DBA manual.

  • Database with many schemas - query schema depending on user

    Let's assume we have a number of schemas in a database (hundred or so), which all contain the same tables.
    The customer wants one application express application which accesses only the schema corresponding to the user that is currently logged in.
    So database schema user1 contains table EMP, and schema user2 also contains EMP. Now the application is assigned both schemas user1 and user2, and when user2 logs in he only sees database schema user2.
    Is this possible with Apex? I've tried both built-in authentication and database authentication for the application, but found out this is truly only about authentication, because the query is always executed by APEX_PUBLIC_USER.
    How can I manage which schema is accessed with the authenticated user?
    Thanks in advance!

    Patrick,
    Every apex application has an "owner" attribute which is used as the parsing schema. All SQL and PL/SQL in your app is parsed as that schema using that schema's privileges. It is as if your application were a definer's rights stored procedure in that schema. The APEX_PUBLIC_USER schema is simply used to create the session and has no bearing on privileges. Currently there is no way to change the owner attribute of an application at runtime. However, your application can operate with any schema in the database according to the privileges granted to the parsing schema. Something along the lines of what you described was discussed at length in the following thread, maybe it will give you some ideas to try out: Access to owner schema throught APIs

  • Oracle troubles with multiple schemas in same database

    We have several different users set up with individual schemas in the
    same Oracle database. We run into trouble when more than one user tries
    to use Kodo in their local schema. Things go fine for User A, but when
    the User B tries to run the schematool on their own Oracle schema, they
    get this nonsense:
    javax.jdo.JDOFatalDataStoreException: An error occurred while connecting
    to the data store.

    It is our suspicion that Kodo is actually selecting the metadata all of

    that jdo_schema_medatax already exists. It really ought to restrict
    itself to the schema it's actually connected to.
    If our theory is correct, it would explain why Kodo is so incredibly,
    horribly, painfully slow to connect to our Oracle database -- we have
    dozens of schemas in there, many of which have hundreds of tables.
    Is 2.3.0 addressing this problem?
    Paul

    Paul,
    Are you using the 'schema-name' system preference setting for each user?
    Oracle's mechanism for selecting database metadata requires that the
    appropriate schema name be explicitly when more than one schemas are used.
    See the database setup section of our documentation for more information.

  • How can I use a mySQL database schema with numeric auto increment primary key instead of GUID?

    Hello!
    I'm using the TestStand "MySQL Insert (NI)" database schema with GUID as primary key. So everything works fine.
    But I prever using numeric values as primary key, because the database is in conjunction with another database which uses numeric values as primary key.
    Is this possible?
    Has anyone an idea how I can modify the "Generic Recordset (NI)" for use with MySQL?
    Thanks!
    Configuration:
    Microsoft Windows XP
    TestStand 3.1
    MySQL 4.1.12a
    MySQL ODBC 3.51 Driver
    Brosig

    Adam -
    The TestStand Database Logging feature does not allow you to run a separate SQL command after executing the command for a statement(table), so I do not think that you can use an auto incrementing column for the tables. There is just no way to get it back in a generic way. One option that I tried is something similar to the Oracle schema where you call a store procedure to return a sequence ID for each record that you want to add.
    So you would have to create the following sequence table in MySQL:
    CREATE TABLE sequence (id INT NOT NULL);
    INSERT INTO sequence VALUES (0);
    Then create a stored procedure as shown below that will increment the sequence value and return it in a recordset:
    CREATE PROCEDURE `getseqid`()
    BEGIN
            UPDATE sequence SET id=LAST_INSERT_ID(id+1);
            SELECT LAST_INSERT_ID();
    END
    Then update the MySQL tables to use INT primary and foreign key values, so the TestStand MySQL SQL file to create all tables would have text like this:
    CREATE TABLE UUT_RESULT
     ID    INT  PRIMARY KEY,
    ~
    CREATE TABLE STEP_RESULT
     ID    INT  PRIMARY KEY,
     UUT_RESULT   INT  NOT NULL,
    ~
    Then update the schema primary and foreign key columns in the TestStand Database Options dialog box to be INT to match the table. For the primary key columns, you will have to set the Primary Key Type to "Get Value from Recordset" and set the Primary Key Command Text to "call getseqid()". This will call the stored procedure to determine the next value to use as the ID value.
    Hope this helps...

  • Is ADF meant for database designed with vertical schema ?

    Hi,

    Thanks in advance.
    Edited by: user8925296 on Apr 12, 2010 10:06 AM

    The short answer is no...
    What you are calling a "vertical schema" is what others have called an entity-attribute-value or universal data model schema. I'd advise you to do some open-minded research about these types of schemas if you are developing a new application before you proceed. They sound great in practice, but have quite inherent usability and scalability issues.

  • How copy the same project with its database schema & deploy it on same PC?

    Hi,
    Firstly, sorry about my forum handle. For some odd reason all the handles that I am trying to create are already in use.
    Right, I am a new Application Express Developer and am managing my own Oracle Database Instance as well. I have managed to create a complete project and I have another client who requires the same project. What is the logic and steps that I can use in making a complete copy of the existing project and use it for my second client. The databse objects would be the same.
    My initial thoughts are to create another database schema as a copy of the current database schema and then do an import/export of the existing project so that the new copy will work with the new schema? I am just talking on top of my head here. I am not a DBA and being new to Application Express administration does not help much either as well.
    Thanks for reading my message.

    Virtual private database basically works by modifying your existing query.
    So you have a table with your clients and a code for each client
    So when client A logs in, he uses an application_context to set his code.
    You have to write the procedure to set the context.
    Now , what you need to do, is to modify your tables so that you can join to your client_code table based on client_code.
    So when client A runs his code, he only sees his own data. When Client B runs he only sees his Data.
    But you , if you run as sysdba can see both sets of data.
    Check out http://asktom.oracle.com and the oracle docs. Oracle expert one on one has a good section on this two (by tom kyte too)
    You really want to satisfy yourself that this is the solution you want. Do the queries run slower. Well, it depends on how well you implement fgac. If implemented well, it will be marginally slower but you will have far less maintenance than an alternative implementation. The big advantage is adding additional clients has virtually no extra workload for you.
    I think you may need to use database account authentication for this to work with Apex. I'm really not sure.
    I suggest you read up on this, and maybe try and set up a 3 table demo app with it. That way you can see whether or not its for you.

  • How to work with oralce database  schemas

    Hi
    I am using Crystal Reports with servlets
    The database has so many schemas.
    the password is the same but the user names are different
    I want to know is how to log in to a schema using java.
    the problem that I faced was the crystal report cannot find the correct
    database schema.
    Pls help me

    According to Metalink Note#160441.1, this isn't possible.
    But, I did figure out a workaround. It is kind of messy, but if you use the javascript onclick even in the insert of the form, you can get the non-database form value and then send it to a dynamic page via a document.location call with the value passed in the url call to the dynamic page. The dynamic page can then run your pl/sql code inside the <oracle> tags referencing the value passed in as :myvaluepassedin.
    This is neat, because it doesn't stay on the dynamic page that you just sent it to, but continues on with the processing of your form.
    So, if you have any further pl/sql commands to run, you can put it in the pl/sql insert event handler and it will run those next.
    I didn't realize that both of these would run for the same form. I did notice that the javascript onclick runs first, then the pl/sql.
