Scripts of objects in a schema.
Hi
I am working on a problem which is:
To generate the scripts of objects in a schema, with separate object types in different folders, with separate files for each object.
For instance if I have a schema called HR then the scripts for all the tables in this schema should be in a predefined folder called TABLES and within this folder the individual scripts for tables tab1.sql , tab2.sql.. and so on. I need to do this for all objects in the given schema. This I need to do from sql*plus and not from any GUI.
For this I am able to figure out some basic steps required. Below is the sample for same
DECLARE
V_SCRIPT VARCHAR2(4000);
CURSOR C1 IS
SELECT OBJECT_TYPE,OBJECT_NAME,OWNER
FROM ALL_OBJECTS WHERE OWNER ='HR' ;
BEGIN
FOR I IN C1 LOOP
with scripts as (select dbms_metadata.get_ddl(I.OBJECT_TYPE,I.OBJECT_NAME,I.OWNER) txt from dual)
select replace(txt,'"') ||'/' script_text INTO V_SCRIPT from scripts;
DBMS_OUTPUT.PUT_LINE(V_SCRIPT);
END LOOP;
END;
{code}
Here in the script I can identify few problems like:
1. The DBMS_OUTPUT.PUT_LINE will work till the buffer level and after that will give an error message. Is there any way to eliminate this?
2. How can I spool the files in the middle of pl/sql code.
These scripts are to be created on a windows system in some location like *c:\scripts\tables\..*,*c:\scripts\indexes\..* and so on.
The database version should be:
{code}
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Prod
PL/SQL Release 10.2.0.3.0 - Production
"CORE 10.2.0.3.0 Production"
TNS for 32-bit Windows: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
{code}
Also I came to know of utl_file package, can I use this for the same.
please provide your expert guidance for the problem.
Thanks
Ansh
Two thoughts:
First: The Oracle database does not have folders. What product are you working in?
Second: Cursor loops such as the one you've written have been obsolete in Oracle for more than 12 years: Why are you writing one now?

How does Apex access and manage db objects in other schemas?
I'm looking for a description of how Apex accesses and manages database objects in other schemas.
I'm sure I've seen such a description somewhere earlier but am unable to find it again...Hi Rene,
When you are connected to sqlworkshop, it is basically connected to the sceham owner of the workspace. If you execute the query
select sys_context( 'userenv', 'current_schema' ), user, username from user_users;you would see the schema and user(currently connected) and schema owner through which you have logged in. The user will have all the privileges granted to schema owner. So basically you get connected through APEX_PUBLIC_USER and it has all the privileges of the schema owner.
In order to run scripts in another schema you would need grants on other schema same like you are connected to user A through sqlplus and wants to create objects in schema B. For example lets say you want to create a table in schema B and you have create table privileges in scehma B , you can execute command create table B.emp as select * from A.emp;
I hope this answers your question.

Create a script that can create entire schema with data when run
Hi,
I need to create a script that creates the entire schema on a database when the script is run. the need is that the script should be capable of creating all schema objects with grants and all, including the table data.
The same objective can be achived through export / import.But we don't want to deliver the dump files instead a script which will be executed on a database created with same database stucture of tablespaces etc.
I have serched the net but yet to achive the goal.
Is there any oracle utility / script file that can do this for me ?
Can Oracle import be used to create the same, the way it is used to create index File ?
Please suggest !!
RegardsYou should look at the package dbms_metadata to be able to extract all ddl to recreate a schema. To load the data, you could write scripts that will generate insert statements and spool these to a file (sql generating sql), or you could write scripts that generates a delimited file and use sql loader to load the data into the target system. There are lots of little gotchas in either of these 2 solutions. The biggest 2 right away. 1 - picking a delimiter, 2 - dealing with carriage returns in text data. SQL Developer is able to do some extraction, so before you go writing this stuff yourself, I would check it out to see if it does what you are looking for before you reinvent the wheel.

Hi,
In short: How to suppress compiler errors without excluding the object from the "Schema Compare" tool ??
A bit longer:
We have a SQL Server 2008 project in Visual Studio 2013 running SQL Server Data Tool.
An old database, with a lot of history in, has been imported into SSDT and there are many syntax errors preventing the project from compiling/running. An typical error is: "SQL70001: This statement is not recognized in this context".
Running the "faulty" scripts on the server, executes just fine. I understand that there are syntax errors and they should be rewritten, but it's not gonna happen just like that - it is a slow process over a long period of time.
I know it is possible to change Build Action to None, but that also exclude the object from appearing in the Schema Compare function/window.
So - how to ignore some compiler errors and still having the objects to appear when doing "Schema Compare" ??
Thank you in advance.Hi Steven,
Thanks for your comments.
Well, it sure does help in the future, but right now i would prefer the other way - to suppress some errors and still allow the scripts to build.
The thing is that if we "rewrite" the objects into create scripts, then we have a huge test job ahead of us + the database environments (PROD vs DEV and UAT) does not share the same AD or DB users and therefore grants is lost if dropping/creating
objects, right!
If you drop a object before creating it, the drop will also drop the roles and grants and since they don't share user table, the create will not be able to add the permissions again. There might be a solution to that, but it is going to be very complicated
for some newbies like us. We need something we can trust.

Unable to access the objects with out schema as prefix.. can any body help
Hi,
i am using 10g.I have one problem like i unable to get the table access with out mention prefix for that table.
but i created public synonym and gave all grants to all users also. but still i need to mention schema name as prefix otherwise it give the error..
can any body tell me reason and give me solution.
ex: owner:eiis table:eiis_wipstock
connect to: egps schema
in this position if i try with eiis.wipstock it gives error but if i mention like eiis.wiis_wipstock then its working fine.Pl do not spam the forums with duplicate posts - Unable to access the objects with out schema as prefix.. can any body help

How to give select prvileges on objects in ONE schema only.
hi.. i wanna to do gve a select on tables only privilege to all objects in one schema only,
is there any single command that enable me to do so ?
or do i have to allocate priviledge to each and every schema objects available ?I think there is no command that will give permission on all the objects in one go.
but u can do it in some tricky way.
some thing like this
spool permission.sql
SELECT 'grant select on '||TABLE_NAME|| ' to abc; ' FROM USER_TABLES
spool off
change the abc user with the real schema name
then run the permission.sql file connected with the user containing the tables.
first try this on some test db and check if it works

Compare DB objects between different schemas
Hi,
I want to compare db objects beween 2 different schemas like QA and PROD.
Please suggest me a tool that compares table definitions,stored procedures and other db objects between different schemas.Did you check the above video link which is shared?
Yes I'd agree with you and also i faced these situations to check what objects i need to export from Dev to Quality ( to analyze what are already correct or what have to be imported again)
Generally Quality & Prod are in sync.
Also will be waiting along with you if anyone comments on any such tool.

How to remove all scripts on object instances?
I'm looking for any kind of solution here, besides disabling the warning.
I hate it when I'm converting someone else's AS2 project to AS3, and there's code buried on an onstage instance somewhere, which gives me the warning:
"Actions on button or MovieClip instances are not supported in ActionScript 3.0. All scripts on object instances will be ignored."
How can I:
A) Find which instances have code on them.
or
B) Remove all code on all instances.
Idea:
Can I save as a different format/version/something and lose this data somehow. Then I could convert it back its current FLA format?YES!!! So awesome!! Thanks

Why does Livecycle Designer need to lock scripting on objects with children that are fragments??
Can someone tell me why Livecycle need to lock scripting on objects with children that are fragments??
I mean, just because I have a fragment (which you can't edit the script for), why does Livecycle need me to NOT edit say the initialise event on the Main form.
Yes, I can remove my fragments, edit and reinsert. Also if the event already has a script, I can edit the xml. But neither of these are terribly convenient.
Couldn't there be a better way?The purpose of the fragment is to create re-usable or standard components. In most cases the fragment is not created by the same person designing the form and they do not want the from designer to modify any part of the fragment (it is a separate XDP file). There may be code in that fragment that relies on the structure that exists. If you have the rights you can always edit the fragment and when your PDF is created the changes will be picked up.
If you want to be able to modify the fragment while it is in Design mode sounds to me like you want to add a component to the object library. This will allow you to have a reusable piece of a form that you can modify on a form by form basis. To do this simply build the piece that you want. Lasso the entire form and drag it onto the Custom library. When you release it a dialog will pop up allowing you to name your component. Now on any form design you can drag your new component onto the canvas and all methods/properties and code will come with that component (allowing you to modify it for that form as you see fit).
Note that you can create your own libraries to hold your components if you see fit. Also if you put your libraries on a shared drive, you can share components between Designers.

Cant view objects from another schemas
Hi everybody!
I have a 10.1.2 Jdeveloper and a 9.2.4 Oracle database.
I successfully created a database connection.
With provided login I can access to tables from another schemas in SQL Worksheet, but I cant see any objects from those schemas in the connection tree.
What's wrong?The Schemas are being filtered so that you only automatically see the schema for the connection that you logged on with. To change the schemas that are visible you need to :
1) Select the connection name in the Navigator (you should see that it has a filter icon overlaid showing that it is being filtered)
2) Invoke the context menu and select 'Apply filters'
3) Shuttle over the other Schemas you wish to see and press OK

"Your script uses objects from a non-existent collection"
I have a multiple page form with a barcode on each form. I created a separate collection for each barcode. The auto generated code looks fine and has the correct collection created, however I still get the error, Paper Forms Barcode error "Your script uses objects from a non-existent collection".
I'm not sure what is wrong and I don't know how to fix it. Anyone else run into this?You will need to create a shared folder in Dropbox, then populate that with what ever folders you need to organize the files. It appears the DropBox app,will not handle this, but you can do, it by logging in to you account via Safari. Once the folders are created, they will show up in the app. Likewise with designating the folders as shared. Anyone you wish to share with will need a Dropbox account. (using the public folder will not work since links out it are for files only, not folders. An odd restriction, but it is what it is).
IF you have copies of the files on a PC, you will find that will be the easiest place to upload them from. If they are only in iBooks on the iPad, you will need to synch and use the file management function to copy them off. not sure if you can synch them back over to DropCopy within iTunes (never tried it).
DEpending on your needs, a couple of apps to look into are iCab Mobile (a browser), and GoodReader (doc viewing and management app). Both integrate well with DropBox. -
Moving objects from one schema to another
Hi,
again as part of my learning exercise, I was trying to move objects from a schema in 10GR2 to 11GR2 database.
I am able to use exp and imp commands to achieve this objective -
On source database -
$> exp userid=scott/tiger owner=(schemaname) file=data.dmp statistics=none
Copied the dump file on target server and then
$> imp userid=scott/tiger file=data.dmp fromuser=uname touser=scott
And this works fine.
What I am not able to understand is how I can achieve this by using datapump instead?
Your help is much appreciated.
Thanks.Thanks.
Worked perfectly.
This is what I did (in case someone is in my position)-
On source database-
expdp scott/tiger schemas=<source schema>directory=DATA_PUMP_DIR dumpfile=data.dmp job_name=some_job
Copied dump file to target server.
On target database-
$> impdp scott/tiger directory=DATA_PUMP_DIR dumpfile=data.dmp remap_schema=<source schema>:<target schema> job_name=imp_kob -
Scripting.encoder object documentation
Greetings,
I need to encode a vbscript (actually in a HTA). Someone has srcenc but it only runs on win xp.
I have found a script which does the encoding which uses the "Scripting.encoder" object that works fine on windows 7.
However, I cannot find any documentation on the properties and methods of this object. Does it exist anywhere?
Thanks
David ZSorry all of these things are obsolete.
In case you missed it, this is the 21st century.
¯\_(ツ)_/¯
and sarcasm is still the lowest form of wit....
Funny how that object can still be used in Windows 8.1 Update 1.
It is still the 21st century and HTAs are obsolete which is why you cannot easily fid documentation.
What script ing options might there be? How about the name of one of the script languages installed. Perhaps "vbscript" or "jscript".
In way I was trying to shy you away from trying to use this as it does not work well on Vista and later systems. It has never worked correctly for HTAs.
There are many third party tools which can obfuscate a script. Look into these.
Here is one obsolete blog on the encode:
http://blogs.technet.com/b/heyscriptingguy/archive/2006/03/09/how-can-i-encode-scripts-within-an-hta.aspx
The encoder control does not work well with HTAs. Try it. You will see that it fails in strange ways.
Microsoft has not supported this control for almost 10 years. Now that XP is gone it will disappear. It currently will not workon mist implementations of Windows 8.1 and 2012.
I first warned people about this control back in 2006. The same people are now coming back wanting fixes that do not exists.
Use PowerShell or XAML for GUIs. They are not likely to be an issue fro the next few years.
If you search for information ou will find that the information was pulled by Microsoft in about 2003. No one should be attempting to use this control anymore and it has been included only for compatibility with no support. If it work OK.
If not - too bad.
The arguments are simple:
Set se = CreateObject("Scripting.Encoder")
se.EncodeScriptFile(strExt,byte_stream,cFlags,bstrDefaultLang)
cFlags is 0 for all but "ASP"
bstrDefaultLang is not needed
strExt is the file extension for the language which is either "vbs". "js", "asp" or the extension of any installed scripting languages that support the encoder.
Search and you will find many examples along with discussions on the failures and some fixes. You will see dozens of answers from me back to at least 2003. I started using the script encode and control in about 1995 when it was first distributed
with Visual Studio. I still have the CDs with the SDK. I will sell them to you if you really want documentation. I will not even attempt to find the docs in that stack of about 30 CDs.
Take my advice please. Do not use obsolete software. If you really want to I have licensed copies of Windows ME that you can have. I even have an old TRS 80 - do you want to buy that?
¯\_(ツ)_/¯ -
Is there a way to access object from other schema?
1. Is there a way to access object from other schema
Without using synonym/public synonym without prefixing schema owner?
2. If you do not see any object in all_objects by same name owned by connected user or public, can there still be objects hidden from this view? for instance synonyms created by SYSTEM
TIA for helpWell, you missed something somewhere. If there is no
ALTER SESSION SET CURRENT_SCHEMA=whoeverthen there must be either public synonym for the object as this shows:
SQL> CREATE USER a identified by a;
User created.
SQL> GRANT CREATE SESSION to a;
Grant succeeded.
SQL> CREATE USER b identified by b;
User created.

SQL> desc test
PROCEDURE TESTITAnother possibility without public synonyms is that crv had granted the other user privileges on some object, and the other user creates a private synonym for that. When crv granted privileges on a different object with the same name, the private synonym became valid again. Something like:
SQL> connect /
Connected.
SQL> drop public synonym test;
Synonym dropped.
SQL> GRANT CREATE SYNONYM TO a;
Grant succeeded.
SQL> connect a/a
Connected.
SQL> desc test;

SQL> desc b.test

SQL> connect b/b
Connected.
SQL> REVOKE EXECUTE ON test FROM a;
Revoke succeeded.
SQL> connect a/a
Connected.
SQL> desc test;
ERROR:

SQL> desc b.test
ERROR:

SQL> DROP PACKAGE test;
Package dropped.
SQL> CREATE FUNCTION test (p_num IN NUMBER) RETURN NUMBER AS

SQL> GRANT EXECUTE ON test TO a;
Grant succeeded.
SQL> connect a/a

FUNCTION test RETURNS NUMBER

P_NUM NUMBER INSo, I would go looking for the synonyms.
