Schema comparison

I am trying to compare two schemas running (both) in Oracle 11g. Is there any tool in Oracle to do that? SQLDeveloper? I tried with a tool called TOAD and I got a report saying that there was no difference. But we know for sure at least one procedure is different because we had changed it before the test (still has the same parameters and return but different logic inside). So, we thought the result was invalid. Anyway, please, let me know what else we can use.
Thanks!

Did you check the options in toad. If you are not comparing procedures then it won't compare them.

Schema Comparisons - Ignore column order

I'm using SSDT for the first time and I want to be able to ignore column ordering when doing schema comparisons.
There was a setting in GDR that I cannot find called - "Force table column order to be identical" - does this still exist?
Also in the old sqldeployment file there was an IgnoreColumnOrder setting. Cannot find either of these.

It's unfortunate that the general attitude of Microsoft seems to be geared towards coming up with excuses and explanations instead of solutions. I was excited to use schema/data compare in VS2013 but found that it's basically useless to us because of the
lack of this feature. I'm just glad there are other reasonable programs on the market to do comparisons (RedGate, for example).
It's evident that each year Microsoft becomes even more detached from reality. People complained about IE, Microsoft didn't solve the problems, and now hardly anyone uses IE. No one is going to use this shoddy comparison tool for the same reasons. You're
just wasting people's time with incomplete products like this, and that's frustrating and builds resentment in the people who are paying to use your products and services. I'll have no problem jumping ship for any given Microsoft product the second a competitor
releases something better.

Comparison of schemas across different database Instances

Hi All,
I need to compare around 8 schemas across 4 different instances. We expect them to be same (atleast constraints and indxes) but we have some exceptions. Don't have any database link. I tried using PL/SQL developer , it gives only changes for source db vs target db. Which is the best tool for this purpose?

Here is for remote Schema comparison:
compareRemoteSchemaDDL.sql
This script compares the database tables and columns between
two schemas in separate databases (local schema and a remote
schema).
This script should be run from the schema of the local user.
A database link will need to be created in order to compare
the schemas.

column this_user new_value local_user

Sending Comparison Report from OEM Grid

Hi All
I have configured a job to compare a schema objects in two database. I used Grid Control's Change Manager for this. I want an email
to be sent me when ever a comparison job completes and this email should
contain the comparison report of the comparison. I need a report same as we use
to have in change manager which comes with Oracle Administration Client and
generates and HTML report of schema comparison. Can you please help me setting
this. I have already setup configuration of my mail server and email adderess
in my OEM Grid control.
Thanks

What you first need to do is set up a notification method.
Then you will need to set up your own notification schedule.
Then add the job you are wanting to run and be alerted on to the notification rules.
Then you will want to subscribe to that/those rules.
Then you will want to check the notification you wish to get in the job itself.

How to compare two oracle database schemas

hi all,
i want to compare and find out differences between two oracle databases. The comparison should be made on between table definition,table data,primary and foreign keys, packages and functions.
Is there any management console or tool embedded in the oracle enterprise manger?
it is really appreciate if anyone can point me towards wright direction asap.

Hi ,
This script would help u a lot in comparing 2 schemas and generate a report on them.
Script:
This script will compare two Oracle schemas and generate a report of
discrepencies and this script has been used against Oracle 7.3.4, 8.0.5,
REM and 8.1.7 databases, but it should also work with other versions.
REM
REM Please note that the following schema object types and attributes are
REM not compared by this script at this time:

REM comments on tables and columns
REM nesting, partition, IOT, and temporary attributes of tables
REM snapshots/materialized views, logs, and refresh groups
REM foreign function libraries
REM object types
REM operators
REM indextypes
REM dimensions

Generic query on documenting and maintaining schema changes -Oracle 10g

Hi All,
This is a generic query and i was not getting any particular forum here to put this for suggestions and help.i have put this in the documentation forum also but havent got any inputs.
Could you all please advise a good and easy way I can store all db related stuff including every detail and minutest change done.
I work as a Oracle-DB developer and it has been particularly difficult to keep track the changes very much.
We have a Development pipeline(a code base for development),Testing pipeline(another code base-for Testing)
and then comes Production Deployment(another one for clients)
Presently,we have all our DDL,SQL,etc everything scripts stored in a sort of shared location but keeping them updated with every change done
in any of the above pipelines is very difficult and I end up finding discrepencies between the stored versions and what is in Testing and Production.
I typically spend a good deal of time doing comparing the entire scripts,schema changes to try to figure out what the right and latest version of a script should be.
So,need your inputs on any particular free tool,best practises and good process for tracking easily and also maintaining db changes.
--Thanks
Dev

The problem with most configuration management systems is that they were made for files, not database objects. Files such as dlls get replaced by the new version upon deployment, but database tables do not. Tables get upgraded with alter scripts. So if you want to maintain create table scripts, you need to upgrade them with every change, as well as creating alter table scripts.
For a free configuration management system, see http://subversion.tigris.org/. Such software will also do file comparisons including version comparison.
For comparing installation scripts to existing schemas, I would create a new schema with the installation script and then compare that new schema to an existing schema using the schema comparison feature in Toad or PLSQL Developer.
Alternately, you can forget about maintaining installation scripts and just take an export without data from your production or test schema whenever you need to create a new installation. You can also extract DDL from prod using the dbms_metadata package. Embarcadero Rapid SQL was also good for extracting DDL.

Schema Compare SqlDatabaseOptions Timeout

Have a small Azure SQL DB (handful of tables and stored procs) that I been able to successfully import into Visual Studio 2013 as a DB project, and all the objects (tables and procs) do get imported properly. But when trying to do a comparison
using Schema Compare tool between my project and the Azure SQL, I keep receiving an error message:
"An error was received from SQL Server while attempting to reverse engineer elements of type Microsoft.Data.Tools.Schema.Sql.SchemaModel.SqlDatabaseOptions: Timeout expired."
I have set my DB project property for target DB to Azure SQL Database, but it does nothing to solve the problem. I have also set that only tables and stored procedures are compared.
I am not sure what am I missing here. Will note that I am using the new DB tier on Azure, but I don't think that makes a difference. My best guess it that my permissions are not set right, but it puzzles me that I was able to import the Azure SQL DB into
the project initially without a problem, where a schema model had to be looked up.

Hi Hrovje Maric,
In theory, the new Schema Compare and Data Compare features in Visual Studio 2013 supports SQL Server and Windows Azure databases. Usually, when you want to compare your working database project with the database, you can use the schema compare by right
clicking on your database project and selecting Schema Compare. However, according to your description, the timeout error occurs when you using schema compare. We need to check if your login have permission to view definition. Or if the database which be used
for schema compare was restored from backups of other place, the users in the databases may lose their SID, you need to delete the database users and recreate them and then restart the schema comparison again.
In addition, you can try to increase the query timeout allowed on the connection. In the Windows Registry, search the key "QueryTimeoutSeconds" and increase the value from 60 to 360 and try to use the schema compare and check if the timeouts error will disappear
Visual Studio 2013.
For more information, there is detail about Schema Compare for SQL Server in Visual Studio 2013,
you can review the following article.

How to compare schema (offline) ?

Hi all,
We have requirement to compare two schema in different location: one is in the server in our office, and the other is one in client site. So this is offline comparation.
What tools can we use for this ?
Thank you for any help,
xtanto

What do you mean by offline schema compare?
You can get an export of schema from your client end and dump the same in a dummy database/user at your office and carry out schema comparison with the copy that you have.
You can use various tools like CA ERwin, TOAD. There are some free/open source schema compare tools available.

Export Schema Compare to HTML Report

I've downloaded and installed the latest SQL Server Data Tools for VS 2012. Is there anyway to export the results of the schema comparison into a report in CSV/Html format? I understand that it can generate the sql diff script, but I want a
readable report that I can use to show to people.

Hi Sean, I think you'll be interested in the recent blog post covering how to generate schema comparison results using MSBuild. This is a command line tool but it supports saving results to a file and event using a custom XSD to define the report contents
if the defaults aren't what you want. The blog post is at
http://blogs.msdn.com/b/ssdt/archive/2014/07/15/msbuild-support-for-schema-compare-is-available.aspx
I believe this will cover your requirements. Regards,

Incremental comparison through goldengate veridata

Hi Experts
I am using Goldengate veridata for schema comparison. Its every time perform complete backup. Is there any option for incremental comparison.
and second issue that its take huge time to compare frequently change table, is there any work arround

thanks alot for your time and help !!!
First Sorry to late reply
Yes i can use SQL predicate for comparison. But i want to know Goldengate Verdiata byself don't take care the incremental policy. for ddl and dml
Suppose i have one table after first time comparison i add one column..., Suppose i dont have lastupdatedby column etc.

Report error:ORA-06502: PL/SQL: numeric or value error: character to number

The oracle application express environment is created by installing the HTTP Server on the windows server and the application express 3.2.1 components on the 11.1.0.7 oracle database on UNIX. The installation is successfully and have not seen any issues during the installation. After completing all the steps, when tried to login and click the application builder or workspace components, I see the error message
report error:ORA-06502: PL/SQL: numeric or value error: character to number.
This error message is seen on most of the pages when trying to accessed and not able to understand the reasons behind it. Its a brand new environment setup and not even presented to developers to test it.
Below error message is always seen when trying to access most of the components like application builder, schema comparison and some other tabs. Please advice
report error:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
Edited by: user589320 on Jun 9, 2011 5:17 PM

I think its better you use APEX 4.x version ratherthan using old version.
You will get more features and some bug fixes and also it's easy for you to get some help when you need.
* If this answer is helpfull or correct then please mark it and grant the points.

Query to compare 2 different tables from 2 different database

Is it possible to write a SQL query to compare 2 Tables from 2 different Oracle Database. Also I need a query to do the same when the database is same.
Thanks in advance

OK, well "compare" can mean one of two things: Compare structure or compare contents. Here is a quick script to compare column structures of two tables on one database:
(select COLUMN_NAME,
DATA_TYPE,
DATA_LENGTH,
DATA_PRECISION,
DATA_SCALE,
NULLABLE
from dba_Tab_columns
where owner=:OWNR1
and table_name = :tablename
minus
select COLUMN_NAME,
DATA_TYPE,
DATA_LENGTH,
DATA_PRECISION,
DATA_SCALE,
NULLABLE
from dba_Tab_columns
where owner=:ownr2
and table_name = :tablename)
union all
(select COLUMN_NAME,
DATA_TYPE,
DATA_LENGTH,
DATA_PRECISION,
DATA_SCALE,
NULLABLE
from dba_Tab_columns
where owner=:ownr2
and table_name = :tablename
minus
select COLUMN_NAME,
DATA_TYPE,
DATA_LENGTH,
DATA_PRECISION,
DATA_SCALE,
NULLABLE
from dba_Tab_columns
where owner=:ownr1
and table_name = :tablename)
If this query returns any rows, then these indicate that there are structural differences between the tables. We do a minus in both directions to ensure that an additional column in either schema will be returned in the query.
If you are going across dblinks to remote tables then you have to amend the "dba_tab_columns" to "sys.dba_tab_columns@yourdblink"
If you also want to compare indexes, triggers, etc then do the same sort of thing for the associated dba_ views for those objects.
And if you want to compare table contents, then often the fastest way is also to check minuses in both directions, if the tables are not too big:
e.g.
(select * from schema1.table@dblink1
minus
select * from schema2.table@dblink2)
union all
(select * from schema2.table@dblink2
minus
select * from schema1.table@dblink1)
local tables, of course, simply omit the "@dblink" issues.
There are tools to help in such things. TOAD, for example, has a pretty good schema comparison tool, and there are plenty of other options out there. But if you need to script this yourself then the logic I've shown is a good starting point.
Cheers,
Mike

Sql table function that compares two tables column structure and returns each difference as a record in the returned table

hi,
Does anyone have or can show me the principle of a such kind of function ?

Want to understand SID concept...

Hello experts,
why not using the value like e. g. customer number directly in the dimension table instead of a SID? So I also could save one table (SID table) and with this on JOIN by linking directly to the master data tables (text, attributes, hierarchies) using customer no. as key.
Am I wrong? Is it only because of this INT4 thing with the SIDs whitch maybe results in better performance?
What I maybe understand is compounding, it seems to be hard to make here a connection to the right master data table. But if I wouldn't have this case, why else could be this SID useful?
Best regards,
Peter

Hello Siggi,
thank you for your answer and the linke you provided. I think star schema concept and using surrogate ID's for dimension tables is absolute clear for me and I see the advantage there.
How I said, faster DB access using INT4 values instead of characters is also a point I understand. On the other side SAP BW offers you to use a line item dimension which saves a join and result in a better performance.
But why not give the BW developers the chance to decide if you want use it? If your InfoObject is a numeric one, you are may be much faster, saving a join and having an even easier to handle value.
What I am interested in is, if SID technology is so deeply part of SAP BW, for example if you want to report on an DSO you also need SID's, what is the real advantage usind SID's every time for access of InfoCube or DSO data?
See, i read for example the following advantages of BW star schema on [this site|http://learnmysap.com/sap-bw/138-classic-and-sap-bw-star-schema-comparisons.html]:
-> Faster access to data than via long alpha-numeric keys. SAP BW use automatically generated INT4 keys for SID and Dimension ID
-> Can model in easy way: Historizing, multi-lingual, and shared dimensions. It is happen because of the excavation of master data from the dimension tables using the SID technique.
-> The query performance is improved here as aggregated key figures can be stored in their own fact tables.
OK, first point about INT4-keys we discussed.
I completly don't understand the second point and why therefore SID's are needed.
Third point depends on disadvantages of the classical star schema compared to bw aggregates, a point I understand
Often I read: The SID table provides the link between the master data and the dimension tables. (like here: /people/githen.ronney3/blog/2008/02/13/modeling-strategies)
But why shouldn't this be possible just with the key value?
Even SAP just describes his enhanced star schema without SID's, but technically SID's are used. Why not use it like SAP itself describes here:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/4c/89dc37c7f2d67ae10000009b38f889/content.htm
