User stats table - columns' names description

Hi,
I have question about creation user stats table. I have created such a table:
EXECUTE DBMS_STATS.CREATE_STAT_TABLE ('PIOTR', 'piotr_sysstats', 'USERS');Here is stats table structure:

Remain case for table column name

Hello, i am a java developer. I had helped my company to develop a java application all the while and before this we are using ms sql server database. Recently, we want to migrate the database to oracle database. The problem is, in our application, we use the resultsetmetadata to retrieve all the table column name and respective data and store in hashtable, but in ms sql server the table column name is not all in uppercase. When our application try to get the data using hashtable.get("aColumnName"), it will fail because in oracle the column name is all in uppercase. There are more than 1000 jsp page and java code that used the same method to get data, so if i want to change all the code to uppercase, it will consume a lot of unproductive time, is there any way to solve this?

I assume that your code builds an SQL statement like "select * from ??? where table_name = '????';".
If this is correct just wrap the table_name in UPPER(table_name).
If my assumption is incorrect then please give more information.

Syntax of DDL options and related (table) column names

Hi,
where can I find something like a mapping between DDL options and related table column names?
For example I do have the table options PCTFREE, FREELISTS and NOCOMPRESS. The related table columns out of user_tables are PCT_FREE, FREELIST and COMPRESS.
PCT(_)FREE wins an Underscore, FREELIST(S) wins an "S" and it is "NOCOMPRESS" if COMPRESS has a value "Y(es)".
Hope somebody can help.

So far I didn't find any information that is not in
the DDL script gernerated from
DBMS_METADATA.get_DDL.Alright, I give you an example:
I create a table with the following DDL:
"CREATE TABLE IntBuch (
int_bunr integer NOT NULL,
int_sdat double precision NOT NULL,
int_hblz char(8) NOT NULL,
int_hkto char(7) NOT NULL,
int_hdat double precision NOT NULL,
KtoNr char(7) NOT NULL,
BLZ char(8) NOT NULL,
CONSTRAINT PK_IntBuch PRIMARY KEY (int_bunr)

CREATE INDEX hkto

COMMENT ON COLUMN IntBuch.int_sdat IS 'Kommentar zu DB-Spalte int_sdat'
ALTER TABLE IntBuch
ADD CONSTRAINT Gutschrift FOREIGN KEY (int_hkto,int_hblz) REFERENCES Konto
ON DELETE CASCADE
ADD FOREIGN KEY (KtoNr,BLZ) REFERENCES Konto
ADD FOREIGN KEY (int_bunr) REFERENCES Buchung
ON DELETE CASCADE
After that I read the DDL with DBMS_METADATA.get_DDL and I get

If there are no more DDLOptions possible than that, it is fine for me. If not, but all kinds of options are to find in only one or two tables of the database ( user_tables for table options, dba_constraints and dba_segments for column options, primary and foreign keys, user_indexes and user_segments for indexes ...), that is fine for me, too. (As long as I get to know which tables are "sufficient" for that.) If it is different than both of that, that's bad.
However if you want to use defaults instead of
absolut values, it is better to remove certain parts,
like the storage clause, from the generated output.I understand this, but I am more interested to have all and not leaving out some of them in order to have the defaults in the database after running the DDL.
A totally different approach could be to
a) create a database link from one DB to another.
b) create table <new_table> as select * from
<old_table@dbLink> where 1=2;I keep that in mind, thanks for that hint.

I need the "Real" Table / Table Column names from a sql view

Firstly, we have a system with ~1000 tables and ~250 views. We have field level security on the table columns (in our code)
Now we have a lot of views which select data from the tables, but I need to get the "Table Column Name" that is linked in the view.
I know there are view columns that is not linked to a specific table column, (or concatenation of columns) so those columns can just return NULL.
From the sample you will see there is a view selecting data from another view. I know it is not the best sql performance (execution path) but that is another topic on its own.
I went through a lot of the sys.* stored procs or sys.* views to try and figure out if there is a view that we can use to get the expected results.
here is the sql code:
if
Exists (select
* from
sys.all_objects
where name =
'AliasView2')
drop view dbo.AliasView2
if
Exists (select
* from
sys.all_objects
where name =
'AliasView1')
drop view dbo.AliasView1
if
Exists (select
* from
sys.all_objects
where name =
'Table4')
BEGIN
alter table dbo.Table4
DROP CONSTRAINT [FK_T4_T3]
alter table dbo.Table4
DROP CONSTRAINT [PK_T4_Constraint]
drop table dbo.Table4
END
if
Exists (select
* from
sys.all_objects
where name =
'Table3')
BEGIN
alter table dbo.Table3
DROP CONSTRAINT [FK_T3_T2]
alter table dbo.Table3
DROP CONSTRAINT [PK_T3_Constraint]
drop table dbo.Table3
END
if
Exists (select
* from
sys.all_objects
where name =
'Table2')
BEGIN
alter table dbo.Table2
DROP CONSTRAINT [FK_T2_T1]
alter table dbo.Table2
DROP CONSTRAINT [PK_T2_Constraint]
drop table dbo.Table2
END
if
Exists (select
* from
sys.all_objects
where name =
'Table1')
BEGIN
alter table dbo.Table1
DROP CONSTRAINT [PK_T1_Constraint]
drop table dbo.Table1
END

Now we have a lot of views which select data from the tables, but I need to get the "Table Column Name" that is linked in the view.
If you are using SQL Server 2012/2014, then you can use
sys.dm_exec_describe_first_result_set (Transact-SQL) to gte the informations.

Please help me I am not seeing Database table column names in field explorer view

Hi,
I am developing a crystal report using eclipse and sql server. After creating connection, when i drag and drop tables, The table name and its columns should apper in field explorer view. Then we drag the columns onto crystal report. Unfortunately I am just seeing only table names but not column names in field explorer view. Could anyone help me?
After downloading eclipse I have plugged in the crystal report using the following instructions
1. Click on the Help menu, and then Software Updates > Find and Install... to open the Install/Update wizard.
2. Select Search for new features to install and click Next.
3. Click the New Remote Site button. This will launch the New Update Site wizard
4. Type the Business Objects Updsate Site for the Name field and the following for the URL: http://www.businessobjects.com/products/dev_zone/eclipse/
5. Click OK to complete the wizard.
6. Enable the newly created Business Objects Update Site checkbox as well as the Callisto Discovery Site (which should appear by default with Eclipse 3.2) and click Finish.
Expand the Business Objects Update Site node and enable the Crystal Reports for Eclipse 1.0.0v555 checkbox.
8. Expand the Callisto Discovery Site and click the button "Select Required". This will automatically select the required Eclipse features necessary to successfully install Crystal Reports for Eclipse.
Thank You

Finding source database table/column name for a column in a view

Hi i need to be able to identify the original database table/column name for a column in a view.
e.g. say i have a view like this
create v1 as select a.name fname, b.name bname, c.name cname,......
from u1.names a, u2.names b. u3.names c
where .....
Now I want to find out that the database table/column name for the fname, bname and cname columns in the view v1, which in this instance is u1.name.name, u2.names.name, u3.names.name.
But i need to be able to do it for any view. Short of parsing the SQL is there an easy way of doing this?
Now obviusly I can't do this for virtual columns but I will know my column is not virtual as it has an index on it.

But i need to be able to do it for any view. Short of
parsing the SQL is there an easy way of doing this?No, parsing the SQL is the only way. Good luck it is not something I would want to attempt.

How to use simple types for table column names ?

Hi,
can any one tell how to to use simple types for table column names?
It is required in internationalizing of webdynpro applications.
Regards,
Rajesh

Hi,
1: define required column names in <SimpleType>
2:use the following code to get those values
3:bind 'text' property of Column headers to context attributes
4:take a context attribute 'Value' as type of <SimpleType>
5:set these values to context attributes
IWDAttributeInfo objAttrInfo=wdContext.getNodeInfo().getAttribute(IPrivate<ViewName>View.IContextElement.VALUE);
ISimpleTypeModifiable simple=objAttrInfo.getModifiableSimpleType();
Map m=simple.getEnumerationTexts();
Collection c=m.values();
Iterator it=c.iterator();
if(it.hasNext())
wdContext.currentContextElement.set<att1>(it.next().toString);
if(it.hasNext())
wdContext.currentContextElement.set<att2>(it.next().toString);
if(it.hasNext())
wdContext.currentContextElement.set<att3>(it.next().toString);

Function with for loop and parameter table/column names ... syntax help

I'm trying to create a function that returns the distinct values and counts from a user defined schema/table/column.
The code below defines an object type [stats_on_column_obj] and creates a single table of this type [stats_on_column_tab].
The function is supposed to take three input variables: p_schema_name, p_table_name, p_column_name and return a table (above).
I can hard code a SELECT statement into the () ... but once I try to convert it to parameters & exec immediate I am stuck. The red section is where the issue is (i think).

BUG: Export DDL and Data fails for mixed case table/column names

Hi there,
I have found a bug in SQL Developer. See details below.
Description:
When "Export DDL and Data) function is used on a table/columns not named in UPPERCASE, sql generated by SQL Developer is invalid.
Steps to reproduce:
- open SQL Developer, connect to DB
- make a table named "lowerCase" (in double quotes, so it won't be automatically changed to capital letters)
- you may also add some columns, for example "lowerCol1", "UpCol2", ALLUPCOL3
- add some data rows to the table
- choose Tools -> Export DDL and Data
- check exporting of tables and data, on "filter" tabs choose your "lowerCase" table
- press "Apply"
Error:
Generated SQL contains invalid INSERTs: mixed-case table and columns are referenced without obligatory double quotes, which yields an error when generated script is executed (see below, relevant line is underlined)
-- DDL for Table lowerCase
CREATE TABLE "DBO_HT"."lowerCase"
(     "lowerCol1" VARCHAR2(100),
     "UpCol2" VARCHAR2(100),
     "ALLUPCOL3" VARCHAR2(100)
-- DATA FOR TABLE lowerCase
-- FILTER = none used
-- INSERTING into lowerCase
Insert into lowerCase (lowerCol1,UpCol2,ALLUPCOL3) values ('lc','uc','auc');
-- END DATA FOR TABLE lowerCase
Remarks
SQL Developer: version 1.2.1, build MAIN-32.13
Oracle DBs: 9.2 & Express
OS: Windows 2000 Professional
If you need any more details/testing, let me know. I'd really appreciate a quick patch for this issue...
Alternatively, do you know of any other simple way of copying a single database (it's called a schema in Oracle, right?) from one computer to another? Possibly something so simple like detaching->copying->reattaching mdf (data) files in SQL Server... I thought that this "Export DDL&Data" function will do, but as you can see I couldn't use it.
I just need a simple solution that works - one operation on source to stuff, get the resulting files to other computer and one operation to have it running there... I think that such scenario is very basic, yet I just can't achieve it and I am simply not allowed to spend more time on it (read: our test project fails, my company rejects my "lobbying" and stays with MSSQL :/ )
Thanks a lot & bye

Thanks for your reply.

You're right. I just wanted to give some very short feedback on my experiences with SQL Developer, so I didn't think starting new threads would be necessary, but as I was writing it became much bigger than I initially planned - sorry about that. I will make proper threads as soon as possible. Having "Edit post" button on this forum would also be useful.

Generally, you're right - in most cases it's true that "switching DBMS is a major commitment" and "you will produce terrible code" if you don't learn the new one.
However, I think that you miss one part of market here - the market that I think Express is also targeted on. I'd call it a "fire&forget databases" market; MySQL comes to mind as possibly most common solution here. It's the rather small systems, possibly web-accessed, whose data-throughput requirements are rather modest; the point is to store data at all, and not necesarily in fastest way, because given the amount of data that is used, even on low-end hardware it will work well enough. What's important here is its general ease of use - how easy is to set up such system, connect and access data, develop a software using it, how much maintenance is needed, how easy this maintenance is, how easy are the most common development tasks as creating a DB, moving a DB from test to production server etc. There, "how easy" directly translates to "how much time we need to set it up", which translates to "how much will the development will cost".
Considering the current technology, switching the DBMS in such systems is not necesarily a major commitment and believe me that you will not produce terrible code. In many cases it's as simple as changing a switch in your ORM toolkit: hibernate.dialect = Hibernate.Dialect.OracleDialect vs MySQLDialect vs MsSql2005Dialect
Therefore, in some part of market it's easy to switch DBMS, even on project-by-project basis. The reason to switch will appear when other DBMS makes life easier => development faster. From that point of view, I can understand my colleagues giving me an embarassing look and saying "come on, I won't read all these docs just to have db copied to test server". And it doesn't mean "they are not willing to learn anything new", it's just that they feel such basic task should have self-explaining solution that doesn't require mastering any special knowledge. And if they get such simple solutions somewhere else, it costs them nothing to change the hibernate dialect.
I think Oracle did the great job with introducing the Express to this "fire&forget" market. The installation is a snap, it just works out of the box, nothing serious to configure, opposite to what I remember from installing and working on Oracle 9 a few years ago. In some places it's still "you need to start SQL*Plus and enter this script", but it's definitely less than before. I also find the SQL Developer a great tool, it can do most of what we need to do with the DB, it's also much better and pleasant to use over Oracle 9 tools. Still, a few basic things still require too much hassle, and I'd say taking your schema to another machine is one of them. So I think that, if you do it well, the "schema copy wizard" you mentioned might be very helpful. If I was to give any general advice for Express line of DB/tools, I'd say "make things simple" - make it "a DB you can't see".
That's, IMHO, the way to attract more Express users.

Yes; see
http://solarmetric.com/Software/beta/3.0.0/b1-docs/docs/ref_guide_mapping_factory.html
for descriptions of the various options.
The three basic ways to store mapping information are: in metadata
extensions, in the database, and in separate .mapping files. IMO, storing
in separate .mapping files is the best -- storing the info in metadata
makes your metadata get really ugly, and storing it in the db makes it
relatively hard to modify (at least, until we release our GUI tool...)

Can you post the command that you used to run the conversion? I just ran
through the conversion process for a small (10 tables or so) schema
earlier today with no problems.

How to find internal table column names

Hi Friends,
I have declared one internal table with 45 fields.
Here is my situation.
I need to create dynamic table with all above 45 fields and some more fields (approx 10 fields).
I got the solution for creating dynamic table. Only thing is
I have to assign all the above 75 columns to other internal table.
is there any way we can read internal table field names in the program.
we can acheive this by hard coding the all 75 field names.
since it is 75 columns, i want to pass one by one field dynamically to the other table.
Pls give me a solution.
thanks in advance.

GUI_DOWNLOAD with Internal table column names

Hi!
I am using FM 'GUI_DOWNLOAD' to download internal table to excel sheet. But, I am finding internal tables values only into excel sheet. I want Internal Table's column name as well. Please help me. and guide me.
Thanks in advance.
-Rupesh kayasth.

Hi Rupesh,
You have two tables in the Tables parameter. One is DATA_TAB where you have to provide the internal table name which data you want to download. Second one is Field Names where you can provide the column names for the internal table fields. Concatenate the column names in a string and pass it to Fields names table.

How to know a table column name in HTML (Hyperion Interactive Reporting).

Hello,
I have a Hyperion Interactive Reporting dashboard section with an embembed table section on it.
The dashboard it will be open only in HTML.
I put the table as Active, so i can interact with her.
So, what I need to know now is how can I know the column name or number when I double click in one cell of the table.
Can anyone help me with this?
Thank you in advance,
Carlos

Views don't have primary keys though their underlying tables might. You'd need to pick apart the view to determine where it's columns are coming from.
You can select the text of the view in question from user_views.
