Database Object names

just curious, since we all know objects names longer then 30 characters are never needed and even more, it is risky and bad to allow it, when oracle will change mysql object names and cut it to 30 characters ?

Then you need to get a life. Look at everything that is going on in the world and ask yourself where this non-problem rates on the scale. The first time you brought it up I chalked it up to an intellectual discussion, even if somewhat pointless and obtuse. To bring it up again tells more about you than it does about Oracle.
Not in our lifetime the real question is, if mysql is working well with names longer then 30 characters, why oracle has a problem with it ?

What is maximum length of oracle database objects name

Hi all,
Can anyone tell me what is maximum length of oracle database objects name .
I guess it is 30 ,correct me if i am wrong thank you.
regards,
P Prakash

Some objects (like synonyms or java classes) can have longer names than 30 chars:
SQL> create or replace synonym empempempempempempempempempempempempemp for emp
Synonym created.though internally oracle will generate short names for such objects:
SQL> select synonym_name from user_synonyms where synonym_name like '%EMPEMPEM%'
SYNONYM_NAME
/969ea190_EMPEMPEMPEMPEMPEMPEM
1 row selected.and not always will the long name be actually usable:
SQL> select * from empempempempempempempempempempempempemp
Error at line 1
ORA-00972: identifier is too long

Validation of database object names

Hello. I need a function that can check whether a given string is a valid database object name. For example:
IsValid('col1') -> Yes
IsValid('col 1') -> No
IsValid('1col') -> No
Is there any build in the Oracle or does anyone have such an UDF?
Thank is advance.

You can use the wildly inappropriately named comma_to_table procedure. It checks the name and generates an exception if it is not valid.
SQL> var s varchar2(30)
SQL> exec :s := 'col1'
PL/SQL procedure successfully completed.
SQL> declare
2    u dbms_utility.uncl_array;
3    n pls_integer;
4 begin
5    dbms_utility.comma_to_table(:s,n,u);
6    dbms_output.put_line ('Valid:   ' || :s);
7 exception
8    when others then
9      dbms_output.put_line ('Invalid: ' || :s);
10 end;
11 /
Valid:   col1

Retrieve all source database object names from an application in APEX 4.0

Hello
I have completed an application developed in APEX 4.0 ( @Oracle 10g database ).
Now we need to migrate the scripts including all database objects that support the application from Schema A to Schema B.
Is there a report I can run to provide me the information like this :
Page number, Name of the database object used ( including table, view and sequence )
This would allow me to examine each database object used in Schema A and make sure the same object and data have been copied to Schema B without missing anything.
Thanks
Susanna

Hi,
On APEX 4.1 there is Database Object Dependencies Report
http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21674/bldr_app_rpt.htm#CEGGAICH
I'm not sure is this feature in APEX 4.0

Fully qualified database object names

Is there a method to determine the fully qualified name of a database object such as a table or procedure? At the moment I compute this from the catalog and schema identifiers but I am hoping there is a more direct way.
Thanks,
KP

give an example for what u r looking for.
which DB ?For example, a Sybase table named "table1" in a schema "dbo" in database "db1" has a fully qualified name of "db1.dbo.table1". I am trying to find a way to do this in a database-independent way. It's not as simple as concatenating the 3 elements together because you have to take into consideration the fact that the database may not use schemas or databases or both etc. I am hoping there is a method or a series of methods that return this information.

Help finding OS-level database object names

Hello all...
I need to perform an online reorganization of some tables on my QAS system.
However, some of the tables have more than 8 characters on SAP and I need to know what's the corresponding object name on the database library at OS level, so I can use the RGZPFM command.
Could you please let me know how to find out the object's name?
I can't find that information on SE14 or SE11...
Thanks

Oracle database object name 30 characters limit

Hi,
I'm working with Oracle since version 8 and I know about this restriction. I was hopping that this will be eliminated in the future, but I saw that in Oracle 11i the same restriction exists.
Does anyone know if it will be eliminated in a future release?
I would like to know if there is a reason why this limitation exists. We are currently developing an JPA application and we have tables that have name with more than 30 characters.
Thanks!

because all table/index names must be stored in the data dictionary and that storage is only allocated for 30 characters

What is the Table/View name for getting the Database Object Dependencies

I am running the Database Object Dependencies report to get the reference of Database Object and their respective Application Component.
Applications xxxx -> Application Reports -> Shared Components -> Database Object Dependencies -> Compute Dependencies
I want to develop a report for the same purpose, Just want to know what is the APEX Tables / Views they are using to run this report, so that I can use the same Tables to create my own report.
Thanks,
Deepak

Hi Andy,
when I am using the following query...I am not getting any result...
select name, type, owner
from all_dependencies
where referenced_owner = 'APEX_030200'
and referenced_name = 'WWV_FLOW_PATCHES'
AND OWNER= 'XXXXXXX' --- (addeed this to the where clause)
I modified the query.....I am getting the result.....
select name, type, owner
from all_dependencies
AND OWNER= 'XXXXXXX'
- But I am not getting which database object(table/view) is using which Application Page/Component like we have in Database Object Dependencies.
- Also what is this REFERENCE OWNER & REFERENCE_NAME ----
referenced_owner = 'APEX_030200'
and referenced_name = 'WWV_FLOW_PATCHES'
I am little bit confused, Can you pl expalin me in details......

Object name stored in Database table

Hi all,
Lets say I have a Database table that contains the name of the window
objects that I want to create and display at run-time, how do I go about
creating that object from the table field wich is a string ?
Example :
MenuTable { ItemNo, IsFolder, ParentFolder, PromptMsgNo, ..., WindowName,
StartMethod }
Then I use this table to fill in a TreeView or OutlineView using a
Subclassed DisplayNode that contains
the WindowName and WindowMethod fields.
When the user selects a node I want to instantiate an object of the type
indicated in WindowName and
do a start task of the method indicated by WindowMethod for WindowName.
How could I code the following lines ? :
theWindow : "--> Content of CurrentNode.WindowName" = new;
start task theWindow."--> Content of CurrentNode.WindowMethod";
Goal :
Be able to customize the menu system without customizing code for each
client.
Any idea on alternative methodes to reach the the goal would also be
appreciated.
Thanks in advance.

Hi Christian,
When the user selects a node I want to instantiate an object of the type
indicated in WindowName and
do a start task of the method indicated by WindowMethod for WindowName.
How could I code the following lines ? :
theWindow : "--> Content of CurrentNode.WindowName" = new;
start task theWindow."--> Content of CurrentNode.WindowMethod";---<<<---
cl : integer = 0;
aLib : Library = task.part.findLibrary(projectName = 'MeineTestKlassen',
distributionID = 'test',
compatibilityLevel = cl,
libraryName = 'meinetes');
aType : ClassType;
myObject : Object;
// myObject : meinNeuesObjektClassTypeName;
aType = aLib.FindClass(className = meinNeuesObjektClassTypeName);
myObject = aType.InstanceAlloc();
myObject = (object)(meinNeuerStream.ReadSerialized());
--->>>---
This code is part of a method that stores objects persistent into a Database
and then restores and instantiates them.
You'll have to put the Name of the Class your Object should be of in the
"meinNeuesObjektClassTypeName" Attribute. Then, aType.InstanceAlloc()
instantitates an Object of the given Class.
Please note that, due to the diefferences between the declared and the
runtime class type (Object vs. whatever class your object is of) you'll have
to cast your Object to the correct class. (I used to create a virtual
Superclass for this, which contains the method(s) to be called and the
needed Attributes and then cast all created objects to that superclass).
(You might also use a Template for this and implement that in all classes
that need it -- but I didn't try it yet, so I don't know if it really
works).
Hope that helps...

Search for objects in database by name

Want to search packages, views, table, functions for an object name 'company_search' . What is the query from data dictionary?
Thanks

user568155 wrote:

ThanksThere are several data dictionary views you can reference, including
* DBA/ALL/USER_OBJECTS
* DBA/ALL/USER_VIEWS
* DBA/ALL/USER_SOURCE (may contain text internally in the TEXT column)
* DBA/ALL/USER_ARGUMENTS
You will have to search the _SOURCE view line by line for packaged procedures and functions. To search packages you will have to loop through the source lines one by one to search for the text you want
A query would look something like
select object_name
from dba_objects
where object_name like '%COMPANY_NAME%';Edited by: riedelme on Sep 20, 2012 9:02 AM

How to get the List of Database Objects (Table/View) for a given APEX Page.

Hi,
I have an application and that consist of pages like page1,2,3,.....
*1.* I want a report which can give me the list of all the Pages1,2,3,....
I am using the following query to acheive this.... THIS IS FINE..
select a.workspace, a.owner, a.application_name, b.page_id, b.page_name
from apex_applications a,
apex_application_pages b
where a.workspace = b.workspace
and a.application_id = b.application_id*2. Now, I want for each individual page*, the list all the database objects (tables/views), which that page is using.
I am using ALL_DEPENDENCIES , but I am not getting the result.
So, want to know if there any view/table, where I can get the Application Pages & there database object list...
Thanks,
Deepak

Hari,
Thanks for the response.
The view APEX_APPLICATION_PAGE_DB_ITEMS will only give me the table name related to any Page Items defined to that page..It will not give me all the database objects..
suppose we have a Page, having a report based on multiple tables and there is no Page items defined on that page, we will not have any value in this ....DB_ITEMS table. same thing if we have define some PL|SQL(using some table/view) in a Process, that will not be populated in .....DB_ITEMS table. I want some thing like all the database objects (table/views/function/procedure/.....) for a particular Page ID.
Thanks,
Deepak

Find object Names in a file and print all those objects Names

Hi All,
I am new to this forum.
I want to know how to read only objects names in txt file. In the text file i have sql queries, package names, Function Name. I need to read all the objects and display out put. The file contains around 20000 Lines.
Please suggest me.

You can use UTL_FILE and use standard/basic file I/O calls like fread() and fwrite() - common amongst most (if not all) programming languages.
You can define an external table for the file, and SQL*Load the contents of the file dynamically via a SQL SELECT statement.
You can load the file into a CLOB using DBMS_LOB and then process it - quite useful if the text file is XML as the XMLTYPE supports parsing a a CLOB containing XML.
I want to pick Each object name put in a separate file line by line.That in turn will need to use UTL_FILE to create an external file.
Keep in mind though that your in a database environment with PL/SQL. The very best place for data is inside the database in SQL tables. Not outside as external files. Thus you need to ask yourself whether dealing this way with external files is the best solution, and a robust and scalable one.
Granted, many times from the database side we need to deal with external files. The optimal method usually is to load that file's data into a database table as structured data - data that can be accessed via SQL and sorted, filtered, aggregated and analysed.
To provide a "file" as output - this should ideally be done directly from structured data (SQL tables). And can be done using HTTP (via a web enabled PL/SQL procedure that supplies the file content as a http Mime stream), using FTP (via <i>UTL_TCP</i>) or as a CLOB via a PL/SQL call interface. Using UTL_FILE is not necessarily the only option.

SSRS Error : Query execution failed for dataset 'dataSet'. (rsErrorExecutingCommand) Semantic query execution failed. Invalid object name 'RPT.*********'. (rsSemanticQueryEngineError)

I am new to SSRS and I am trying to migrate reports from 2008 to 2012. As I have so many reports to migrate, I simply got the back up of ReportServer,
ReportServerTempDB, and Encryption Key and restored them to test environment. I made necessary configuration from RS configuration tool. I am able to see the reports now when I browse //hostname/reports. But when I open any particular report I am getting some

Hi Kishore237,
According to your description, you migrated some reports from Reporting Services (SSRS) 2008 to 2012. Now you get error when accessing the reports on SSRS 2012. Right?
In this scenario, did you modify the report data source in database after migration? You can try to open the report in Report Builder or Report designer and check the report dataset. If you can preview the report in Report builder or Report designer,
please try to redeploy the report to Report Server. If it is still not working, please try to restore the database from backup. And for migrating reports, please follow the "Content-Only Migration" in the link below:

If you have any question, please feel free to ask.

Forced to remap one database object at a time

Our application exposes a set of data objects (views) for external reporting. Field/row level data security conditions are built into the view definitions. Different access levels are segmented by schema names and in order to enable report reuse object names are identical between schemas.
Users granted schema rights based on their access level.
For example, user A is granted access only to the schema X which contains View1, View2, etc. while user B is granted access only to the schema Y which also contains View1, View2, etc.
User A can reuse report created by user B (since object names are identical), however s/he cannot do it without first changing the data source location (since their access levels and therefore schema names are different).
However, "Set Datasource Location" dialog (see sample screenshot below) does not allow one-click schema remapping. "Current Data Source" hierarchy does not directly expose schema name (it is listed as an "Owner" property of the individual table/view object) which forces user to remap one database object at a time by expanding top and bottom trees, highlighting matching objects and clicking "Update" button.
Our question is: are there any menu items/settings or any other facilities in Crystal Report that would allow us to make re-mapping process less time-consuming?

Hi Len,
No, bottom line is the designer is used to "finalize" the report. It's not designed to be use this way. What I suggest you do is create an application that can set location/schema at view time to that person logging in. This way it's all done in the back end and relatively easy to do using one of our SDK's.
Depending on what development tool and Report engine you use depends on which forum to post your question to. SAP will not create the application for you so you will need to get a developer involved.
Thank you

Hi,
“All but one database are upgradable. However, one database gives:
Invalid object name 'Webs'.”
Did the sentence you mean only one database not upgrade to SharePoint 2013 and given the error?
One or more of the following might be the cause:
Insufficient SQL Server database permissions
SQL Server database is full
Incorrect MDAC version
SQL Server database not found
Incorrect version of SQL Server
SQL Server collation is not supported
Database is read-only
To resolve the issue, you can refer to the following article which contains the causes and resolutions.
