Client Tools :: Basic Tools For Oracle Version Control
Aug 26, 2011I'm looking for 3 simple things.
1) A reverse engineering tool that I can point to an Oracle schema and get a "baseline" script to re-create that schema from scratch, with decently formatted DDL files (1 per object) neatly organized in a directory tree (by object type) and called in the correct order. Icing on the cake would be an option to pass the tool a list of tables containing static data and get DMLs to populate (insert) those tables as part of the script.
2) a diff tool that I can point to a pair of Oracle instances (source and target) containing a given schema and get a "delta" script to alter the target schema so that it becomes identical to the source schema. If data loss occurs on the target instance (i.e. drop a column) I would like to find a warning comment inserted in the script (e.g. "-- Attention: data migration DML needed here?"). Icing on the cake would be an option to pass the tool a list of tables containing static data and get DMLs to update (delete, update and insert) the data in the target tables to become identical to the contents in the source tables *without* deleting and re-inserting all rows (or dropping, recreating and repopulating the table).
3) I would like the above two tools (that, as you will have recognized, are basic to putting your database design under version control) to be open-source, with a command-line interface and a vibrant community backing them.
Basic Join Not Working?
Apr 20, 2008 am not very experienced with SQL. I have two tables:
Class
-----
ID (int)
Teacher (nvarchar)
Subject (nvarchar)
Student
--------
ID (int)
ClassID (int)
Name (nvarchar)
I am trying to write a SQL query that will give me the total number of students in each class. I have tried the following:
SELECT
c.ID,
c.Teacher,
c.Subject
COUNT(s.ID)
FROM
Class c LEFT OUTER JOINT ON Student s c.ID=s.ClassID
Unfortunately, that gives me an error of:Column 'Class.Teacher' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
I'm afraid if I place everything in a GROUP BY clause, I will get some invalid results.

View 2 Replies View RelatedServer Administration :: Query On Redo And Undo Basic Concept
Nov 17, 2010understanding a redo/undo concept . Refer following data
create table t(n number);
insert into t values(10);
commit;
now I update as following
update t set n=20;
As per my understanding the before image i.e. n=10 is stored in undo (to be used for rollback, transaction recovery and even in instance recover but not in media recovery) and after image n=20 is stored in redo (to be used for various recovery purposes including media recovery in case of consistent backup).
So it is redo logs for rolling forward and undo for rolling back making transaction, db consistent . If my above understanding is true then what is meant by the term 'redo required for undo'?
Also, if there are 2 database db1 and db2 connected using database link where we are populating t1 table in db1 using t2 table in db2 using db link where redo and undo will be updated db1 or db2?
Application Express :: Dashboard And Basic Input Forms And Reports
Oct 29, 2012I have been tasked to look at a technology / frameworks that will allow our company to develop tools that is quick and easy to learn and easily supported. We use Oracle architecture extensively in the organization and also have APEX 4.2 installed for development purposes. We have two basic requirements or functionality that we need to implement and I and now looking at a proof of concept to determine whether we should adopt APEX or not.
1. Forms Based Tools
We have many databases with static content and users would like to have access to the data via a form. The form will allow the user to enter parameters (eg date) and on hitting a "Submit" Button, the database will be queried and a report generated and presented.
2. Diagnostics Tools
This is a bit more involved and we require a view of our static data in real time. If a specific KPI threshold is violated (eg MOC < 85%) we would like to present an alarm on a dashboard showing the alarm. For example if there are 5 entities that MOC < 85% we would like to show a "red" indicator. If no entities violate a threshold and are above MOC > 85% we want to show a green indicator. We also want a drill down function, where if the indicator is "red", a drill down will show the details of all the entities that have violated the threshold.
I have described our basic requirements, but if it can easily be done in APEX we will definitely motivate for its use.

PL/SQL :: Difference Between Oracle DB 11.2.0.1.0 And 11.2.0.3.0?
Dec 18, 2012When I use this sql: CREATE USER testuser IDENTIFIED BY "welcome1 " to create user in Oracle DB 11.2.0.1.0. I can login with testuser/welcome1, please notice the welcome1 is not end of black space in login.
But when I do the same thing in Oracle DB 11.2.0.3.0. I can't use this user login with any password. I tried welcome1, "welcome1 " but all failed.
Why there are this difference between 11.2.0.1.0 and 11.2.0.3.0, and since in 11.2.0.3.0 the create sql are success, what password is correct when login?

View 9 Replies View RelatedServer Administration :: Difference Between A User And Schema On Oracle?
Apr 26, 2010difference between a user and schema on Oracle.By difference, I do not mean what is a user and what is a schema.
I understand that if we create a user, the schema gets created by default for that user. Does that mean that we cannot create a user/schema alone.
What if I just want to create a user and grant him some read access on an existing schema or just want to create a schema.

Server Administration :: Difference In SQL Results From Oracle 9i To 11gR2?
Jan 2, 2011I've migrated from Oracle 9i to Oracle 11gR2, when i'm checking my application on Oracle 11gR2, i found that some of the query result are differed from the previous version of Oracle 9i, which is very illogical to me. I've checked the data for all related tables which are involved in one of the query. I've checked all indexes also. Still i'm not convinced that Oracle is doing anything wrong. I cannot recreate the whole scenario here, because of many tables involved in that query.
One of the sample query code.

RAC/ASM Clusterware Installation :: Difference Between Enterprise And Standard Edition For Oracle
Mar 18, 2013In our current setup we have RAC on standard edition and client is now planning to go for Enterprise Edition but not yet decide because of cost. Is there any difference between Grid Infrastructure 11gR3 Enterprise edition and Standard Edition ?
They told me to first install Enterprise Edition and then will move to Standard Edition if they can't get the EE license so in that case do i have to re-install Grid infrastructure for standard edition?
Networking And Gateways :: Oracle 11gR2 Database - Performance Difference Between Windows PC And On VMware
Feb 9, 2012We are having major differences in performance when accessing an Oracle 11gR2 database from two different environments.
I won't sadden you with the gory details of the full application but I will use an indicative example of our problem.
We have SQL Developer in both environments. In each of these SQL Developer instances is a defined a connection to the same database on another machine. So there is the PC looking at a database and a virtual instance looking at the same database.
Selecting the '+' sign next to 'tables' for that connection, on the PC the list of four tables comes back in 4 seconds but on the virtual instance the list of the same four tables comes back in 1 minute and 50 seconds.
This sort of timing issue is repeatable for all accesses to the Oracle database on the third machine.
Installation :: Oracle Database Express And Other Editions Installation Doc Difference?
Mar 20, 2013My question is; I've been reading the Oracle database 11g R2 documentation at this link [URL]...
I passed a couple of days learning about all installation configuration parts including the desktop class and server class.As I was learning, So I had already downloaded Oracle Database Express 11g R2 for win32.
So as i had finished the installation guide I thought it's time to install the oracle now. I did it, and what I found was that there was not any option during installation that i read in above documentation. While trying to find about this difference i reached on documentation[URL]...
That is for express version only.
My question here is, Express edition, we use for learning purpose, But it doesn't look like it has all the stuff that we should learn during installation And what documentation I should follow from my above given two links?
