Generating ddl script in oracle

Hi ,
i ned a script to generate ddl's for all the objects in a particular schema.
i used the DBMS package dbms_metadata.get_ddl
SELECT 'select dbms_metadata.get_ddl('''||OBJECT_TYPE||''','''||OBJECT_NAME||''','''||OWNER||''') from dual;' FROM DBA_OBJECTS WHERE OWNER='RSEXT' AND OBJECT_TYPE='TABLE'
by using the above script i am not getting the complete script.
how can i get the complete script.
can anyone suggest me.
thanks in advance.

Hi,
two different way:
a) write a small shell-script around the sql script an execute the shell-script from the scheduler.
b) writh a pl/sql procedure which executes the ddl-statements using "execute immediate"

Including Schema owner when generating DDL scripts

Designer 9.0.4.6
How do i set the option to include the schema owner prefix in the DDL scripts being generate ("generate server model from database") in design editor?

Generating from the DB Admin tab does not prefix the objects I am generating with the schema name. There isn't a generator preference (that I've found at least) to accomplish this. Has anyone been able to generate database objects prefixed with the schema name?
Thanks,

DDL script in Oracle Scheduler

Hello,
Right now I have a DDL script and I would like to submit this script to the Oracle Scheduler under the Oracle Enterprise Manager (i'm using 10gR2). I tried using Program but it keeps saying some path error problem. I tried using PL/SQL but I don't know the code to execute the DDL script (so many lines that i can't copy and paste to the scheduler, but i have it in a seperate file). Can anyone help on this one?
Thanks,

Generate DDL script tailoring

I would like to know how to tailor the sql script generated by JDev
(11.1.1.0.0) - offline database source).
I've reversed engineered a schema and modified a number of tables (in
10g). I would now want to generate a complete "create script", but
without any of the storage clause (so it can be ran in another schema in another tablespace, for example).
I would also like to tag on some tables a number of DML
statements. Could I add 'pre' or 'post' scripts attached to db objects/tables?
I would appreciate any help either on how to do it, or where I could
look to find more info on doing this.

Generate DDL works in old version of SQL Developer, but not in new versions

Hello all,
How to generate DDL in new versions of Oracle SQL Developer for production Oracle database?
For production database, the generate DDL feature works fine in old versions (version 1.5.5) of Oracle SQL Developer, SQuirrel, Toad and many other similar tools, but not the new versions of Oracle SQL Developer (such as 2.1.1.64.45).
The SQL tab for a table is blank for me in production databases. Of course, it works fine in development Oracle database.
I did some research that many articles describe SELECT_CATALOG_ROLE as the required read-only role in production database. Our DBA did a test to grant me this role temporarily, and it worked for me to generate DDL using new Oracle SQL Developer. It is pain for me to ask for this role.
Is there a plug-in or work-around, so the new versions of Oracle SQL Developer can have this generate DDL feature in production without the mentioned SELECT_CATALOG_ROLE?
I could not find the answer in older forum threads.
For now, I will have to install older versions of Oracle SQL Developer.
Thanks

I've seen a couple posts about people not being able to generate DDL for other users. To date, I've never seen a anybody post a workaround, nor have I seen one of the developers post a response, nor have I seen anybody say they've submitted a SR.
I think I remember reading somewhere that the new version of SQL Developer uses dbms_metadata.get_ddl to generate DDLS, rather than some custom query built on top of catalog views...which could explain why it use to work, but no longer does. But whether or not this is true, I don't know.
You could try submitting a SR and see if Oracle responds saying that it's a known bug and will be fixed in the next release. Until then, unless you get the role, you're stuck using something else for DDL generation.

Validate Rules on Generating DDL

Hello,
What to do to create custom rules to be validated at the moment of generating DDLs ?
Regards
Nelson Antonio Alberti da Rosa

Hi Nelson,
Maybe I misunderstand, but I think you're missing something. Purpose of the design rules is to check your model (logical, relational, and process models) before generating DDL script. So there are only two places that you can apply some (all) rule:
1. From the menu tools->Design Rules->Design Rules
2. From DDL Generation Options screen, there is 'Design Rules' button at the bottom
DDL generation will not stop if some of the design rule is not met. If there is design rule error it will not go in DDL script.
So, everything you did is fine. If the rule works from above two places - it's Okay.
Please elaborate if I misunderstood.

How to generate the DDL script of all the schema objects.

Hi All,
I just wanted to make centralized repository for Oracle database and to create a base version, I need to create the DDL scripts of all the database objects so that i can check in the same ddl scripts (sql) files in to my central repository.
I need do this schedule job which will generate the ddl scripts once in a month(This should be automated process)
Please help me out about this.
Oracle version - 9i
Thanks in advance.
Thanks,
Santosh
Edited by: Santosh_Oracle on Feb 23, 2011 10:26 PM

It is definitely possible to revise the script.
Look at it, you already have 80 percent of it for free, and you didn't even need to Google.
Just ask a FAQ in a forum loaded with FAQs!
And Toad can save everything to one script per object.

Oracle SQL template to create re-usable DDL/DML Scripts for Oracle database

Hi,
I have a requirement to put together a Oracle SQL template to create re-usable DDL/DML Scripts for Oracle databases.
Only the Oracle DBA will be running the scripts so permissions is not an issue.
The workflow for any DDL is as follows:-
1) New Table
a. Check if the table exists from the system/admin views.
b. If table exists then give message "Table Exists"
c. If table does not exist then execute DDL code
2) Add Column
a. Check if Column exists for a given table from system/admin views
b. If column exists in the specified table,
b1. backup table.
b2. alter table to make changes to the column
b3. verify data or execute dml script convert from backup to the new change.
c. If Column does not exist
c1. backup table
c2. alter table to add column
c3. execute dml to populate column with default value.
The DML scripts are for populating base tables with data required for business operations.
3) Add new row
a. check if row exists by comparing old values of each column with new values to be added for the new record.
b. If exists, give message row exists
c. If not exists, add new record.
4) Update existing record (We have createtime columns in these tables so changes can be tracked)
a. check if row exists using primary key.
b. If exists,
b1. deactivate the record using the "active" column of the table
b2. Add new record with the changes required.
c. If does not exist, add new record with the changes required.
Could you please help with some ideas which can get this done accurately?
I have tried several ways, but I am not able to put together something that fulfills all requirements.
Thank you,

First let me address your question. (This is the easy part.)
1. The existence of tables can be found in DBA_TABLES. Query it and and then use conditional logic and execute immediate to process the DDL.
2. The existence of table columns is found in DBA_TAB_COLUMNS. Query it and then conditionally execute your DDL. You can copy the "before picture" of the table using that same dba view, or even better, use DBMS_METADATA.
As for your DML scripts, they should be restartable, reversible, and re-run-able. They should "fail gracefully" on error, be written in such a way that they can run twice in a row without creating duplicate changes.
3. Adding appropriate constraints can prevent invalid duplicate rows. Also, you can usually add to the where clause so that the DML does only what it needs to do without even relying on the constraint (but the constraint is there as a safeguard). Look up the MERGE statement to learn how to do an UPSERT (update/insert), which will let you conditionally "deactivate" (update) or insert a record. Anything that you cannot do in SQL can be done with simple procedural code.
Now, to the heart of the matter...
You think I did not understand your requirements?

Generate DDL - change is a new column and I want to generate a alter table

Morning all,
I have searched and looked all over the data modeler and I cannot find this option ... yet I did find it easily in Designer.
I hope you can help me.
SQL Developer Data Modeler v3.0.0.665.
I have added a new column to a table and when I generate the DDL I would like it to be an alter table add column rather than a create table.
This feature is in Designer so I would think it would be in data modeler.
Just incase my description is not clear here are the high level steps so it is clear.
1. create the logical model
2. create the relational from the logical.
3. create the physical from the relational.
4. generate DDL and run in database. At this point I go to production with my system and all is well.
5. At this point we have an enhancement request. For the model it will be a new column in a table.
6. update logical model.
7. update relational from logical
8. update physical from relational
9. generate DDL. Here I would like to have the generate be aware the it needs only to generate an alter table add column and not create the table.
This is something I do alot as all my models are in production. I cannot find how to do this step of getting data modeler to generate the alter.
Designer does this exceptionally well.
Quite often it is more than a single column. The changes can be many and made over time and at the time of generating the DDL you may not recall every single change you made. To have the tool discover those changes for you and generate the appropriate DDL is a feature I regard as very high.
I hope this is clear and you can help me.
Cheers
Chris ....

Hi Chris,
you need to compare your model against database - import from database into same relational model and use "swap target" option - in this case "alter statements" against database will be generated.
You can look at demonstrations here http://www.oracle.com/technetwork/developer-tools/datamodeler/demonstrations-224554.html
Probably this particular one will be most helpful http://download.oracle.com/otn_hosted_doc/sqldev/importddl/importddl.html
Soon or later your changes will require table to be recreated and you'll need to backup your data - you can consider usage of "Advanced DDL" option - script will be generated that will unload the content of your table (including LOBs) to file system accessible from database and restore it after changes. Well don't try it directly on production system :).

Problems Generating DDL

Has anyone else encountered problems when generating DDL Files for export?
I am using a hosted version of Application Express: Application Express 4.0.2.00.07 at this time and when I go to Generate a DDL file for export, it creates the file, but I am finding that it does not format the file correctly.
Is anyone else experiencing this?
Below is an example of what happens: (It seems that it does not do a carriage return between the ; at the end of a create statement and the CREATE that begins the next statement) <b> ;CREATE TABLE </b>
CREATE TABLE "ANALYST"
   (    "ANALYSTID" NUMBER,
    "LASTNAME" VARCHAR2(30),
    "FIRSTNAME" VARCHAR2(30),
    "EMAIL" VARCHAR2(100),
    "WORKPHONE" VARCHAR2(25),
    "CELLPHONE" VARCHAR2(25),
    "ONCALLSTATUS" VARCHAR2(25),
    "ALTEMAIL" VARCHAR2(100),
    "ALTMESSAGING" VARCHAR2(100),
    "MESSAGING_TYPE" VARCHAR2(15),
    "TEXT_CONTACT" VARCHAR2(50),
     CONSTRAINT "ANALYST_PK" PRIMARY KEY ("ANALYSTID") ENABLE
   ) ;CREATE TABLE "APPLICATION_LOV"
   (    "APP_DISPLAY_VAL" VARCHAR2(255),
    "APP_RETURN_VAL" VARCHAR2(255),
    "PARENT_LOV" VARCHAR2(30),
    "APP_LOV_GROUP" VARCHAR2(30),
    "MSGID" NUMBER
   ) ;CREATE TABLE "RCCA_MAIN" It also seems to break on altering tables as well.
;ALTER TABLE "CORRECTIVE_ACTION" ADD CONSTRAINT "CORRECTIVE_ACTION_CON" FOREIGN KEY ("RCCAID")
      REFERENCES "RCCA_MAIN" ("RCCAID") ON DELETE CASCADE ENABLE;ALTER TABLE "INC_NOTES" ADD CONSTRAINT "INC_NOTES_CON" FOREIGN KEY ("INCIDENT_ID")
      REFERENCES "INCIDENT_DETAILS" ("INCIDENTID") ON DELETE CASCADE ENABLE;ALTER TABLE "PBM_LOB_SUBCATEGORY" ADD CONSTRAINT "PBM_LOB_SUBCATEGORY_CON" FOREIGN KEY ("LOB_NAME")
      REFERENCES "PBM_LOB" ("LOB_NAME") ON DELETE CASCADE ENABLE;CREATE UNIQUE INDEX "ANALYST_PK" ON "ANALYST" ("ANALYSTID") So I am just seeing if this is a bug in this version of the application or if there is something I might be doing wrong when I generate the DDL for output to a script file.
To fix it, I open the file and add the add a carriage return between each CREATE statement and ALTER TABLE statement. This can be quite cumbersome if you have a large amount of tables involved in the application. It does work, but I just don't believe that to be the required action to port an application for export.
Thanks for any feedback
Wally

You don't need to access to your instance with SQL Developer. You can copy/paste the generated DDL code into the SQL Developer (downloand and install http://www.oracle.com/technetwork/developer-tools/sql-developer/overview/index.html), and use it for formatting the code.
Btw, yes generated DDL code has no carriage returns between create table codes (I tested)
