Toplink JPA forces database table and column names to UPPERCASE! Why?

I have recently experienced using Toplink JPA while using glassfish ... migrating an existing application to EJB 3.0 persistence. Toplink JPA, as implemented in glassfish, forces tablenames and column names from my code to be uppercase in select statements, etc. as then submitted to the database. Why? I cannot find anything in the EJB 3.0 specs on persistence that even suggests this.
This created a serious problem for me, in my application. For my code to work I had to change the names of the database tables to all uppercase, even though that meant other of my applications, already written using the original mixed case names of the databases, will no longer work unless I revise the code in those applications! (I am using mySQL as my database.)
In both Unix/Linux and Java, which are both case sensitive, If I wanted names of files or other items to be uppercase, I would have written them that way. I do not expect some middleware piece of software to muck around with the case of text I have put into my code.
I am hopeful this 'feature' of the reference implementation of the EJB Persistence API will be corrected in a subsequent version. [Maybe you can tell I am not happy!]
Thanks for listening to my rant.

Robert,
I found that the name I specify in all of my @Table, @Column, ... annotations is used with the case as it is provided.
If TopLink determines the schema information through defaults then the names it comes up with are definitely upper cased by default.
Are you specifying the schema information that you want in annotations or XML?

List tables and column names a stored procedure is querying

Hello,
Is there a way to list tables and column names that a stored procedure is querying, i.e, selecting from, using T-SQL? If yes, is there a way to also show data types for the columns that a stored procedure is querying, i.e, selecting from?
Thank you,
Lenfinkel

One way to view the dependencies of an object is to use SSMS; navigate to the object, right click and select "view dependencies". However this does not tell you what columns are being referenced by the Stored Procedure.
One way to view what is being referenced by a stored procedure is to run something like
select
text
from syscomments
where
id in
(select id
from sysobjects
where
name
=[Your Object Name]
And xtype
in
('p','P')

How to get table and column names thats being used in SQL , that's generating all my reports on SSRS.

Good day,
I searched through the forum and cant find anything.
I have around 300 published reports on SSRS and we are busy migrating to a new system.
They have already setup their tables on the new system and I need to provide them with a list of table names and column names that are being used currently to generate the 300 reports on SSRS.
We use various tables and databases to generate these reports, and will take me forever to go through each query to get this info.
Is it at all possible to write a query in SQL 2008 that will give me all the table names and columns being used?
Your assistance is greatly appreciated.
I thank you.
Andre.

There's no straightforward method for that I guess. There are couple of things you can use to get these details
1. query the ReportServer.dbo.Catalog table
for getting details
you may use script below for that
http://gallery.technet.microsoft.com/scriptcenter/42440a6b-c5b1-4acc-9632-d608d1c40a5c
2. Another method is to run the reports and run sql profiler trace on background to retrieve queries used.
But in some of these cases the report might be using a procedure and you will get only procedure. Then its upto you to get the other details from procedure like tables used, columns etc

Query to Find Table and Column Name by using a value

Dear Legends,
I hope and surfed in our forums and google to find the Table Name and Column Name by having a value(Number/String). And my where clauses are
where owner NOT IN ('SYS','SYSTEM') and
data_type IN ('CHAR','VARCHAR2','NUMBER')
May I have your help for building the query. and my query as follows
select a.owner, c.column_name, c.data_type, c.owner, c.table_name
from dba_objects a, all_tab_cols c
where a.owner NOT IN ('SYS','SYSTEM') and
where c.owner NOT IN ('SYS','SYSTEM') and
where c.data_type IN ('CHAR','VARCHAR2')
order by a.owner
Thanks,
Karthik

You can use
select * from user_tab_columns a, user_tables b
where a.table_name = b.table_name
and a.data_type in ('NUMBER', 'VARCHAR2', 'NCHAR', 'CHAR');
Or if you want to user DBA_* tables, you can use.
select * from dba_tab_columns a, dba_tables b
where a.table_name = b.table_name
and a.owner = b.owner
and a.data_type in ('NUMBER', 'VARCHAR2', 'NCHAR', 'CHAR')
and b.owner not in ('SYS', 'SYSTEM');
And now when I look a bit more closely, you don't need DBA_TABLES there. dba_tab_columns alone is sufficient. And requirement is still not clear yet. Why you need a group by there? If I get it right, you can use this.
select * from dba_tab_columns a
where a.data_type in ('NUMBER', 'VARCHAR2', 'NCHAR', 'CHAR')
and a.owner not in ('SYS', 'SYSTEM');
Whether you use group by or not, the query will give you the same output.

How to view all tables and column names from a remote database

Hey Guys,
I have a database in a remote server. I have the db link and the schema name.. Now i want to view all the tables in the remote database with column names.. I dont have access to that database using sql developer.. But i can view some tables using the db link..Is there any way i can view all the tables with the column names?

user10683742 wrote:
Dont think i have DBA access..It gives the following error
ORA-00942: table or view does not exist
00942. 00000 - "table or view does not exist"You don't have to have 'dba' access, per se. You just have to have SELECT ALL TABLES privilege. when you use a db_link, you are connecting to the remote db with the user defined in the link, and .. on that db .. you will have the privileges of the user defined in the db link. Exactly as if you had used sqlplus to connect to that db with that user.

Generating mixed case for table and column names

I trying to get table definition from Oracle 9i database into my toplink workbench
(version 9.0.3), the column names and table names are capitilized by
default, how do I change this to be mixed case? Thanks

I'm not sure why you want them changed. The Oracle database by default is case insensitive, which in essence means it converts everything to upper case when a case is not specified (which can be done by wrapping it in quotes). Unfortunately, Java strings are case sensitive. This means that if you try searching resultsets for "TableName" when the database driver is returning "TABLENAME", you will run into problems. It is probably better to have your project match your database as closely as possible to avoid any issues later on.
That said, I don't know of a way to automatically have the workbench use mixed case names - it uses the strings as they are returned from the database. I believe you will need to manually change the table names if you want them to be different than what you have imported.

Chris

Displaying table and column names

i have a user that created a table, he is not sure of the name of the table. how do i display a list of tables and display the column names within a table??

You would need to know who the user is, or alter the following script.
The script waits for 2 entries:
1- the tablenames that start with the first characters entered;
2- the columns that start with the first characters entered;
(If you want to search for "any" tables and/or columns that contain the charatcers you enter, preceed the parameters entered with a % sign).
(If you want to search for "any" table or character, do not enter anything.
This is a "raw" script that should do job. I think it should do the minimum you are looking for.

Case sensitive table names and column names in 8i or 9i databases

Hi everybody,
I've got a couple of business-side colleagues who insist that Oracle table and column names are case sensitive. That is, there is a setting in the set up of a database that lets you pick if table and column names are case sensitive. For example, this would mean that there could be a table named EMP in a given schema schema plus a table named emp in that same schema.
Can this be true? I'd be surprised of course, but I've been surprised before.
Thanks for any direction.
-- Bill Loggins

You can do it, but I would avoid it like the plague.
SQL> create table "a" (b date);
Table created.
SQL> create table "A" (b date);
Table created.
I think I would refuse to work on a database where this has been used !

Toplink changes table and columns to uppercase

I found a way to make toplink not to change table and columns to upercase with setShouldForceFieldNamesToUpperCase=false setting (which should be false be default but so some reason isn't.)
However, when toplink is used with JSF how can setShouldForceFieldNamesToUpperCase be set to false? Is there a way to do it in persistence.xml or perhaps there is a better way altogether? (I know i can use @Table and @Column but that is a lot of redundant code if all the fields in java have exact match in DB and i am looking for a cleaner solution.)
My setup is a follows
toplink v2-b49
mysql 5.0 (with 5.0.5 driver)
servlet/jsp 2.5/2.1
jsf 1.2
tomcat 6.0.13
Thanks

Thanks Doug
I Created that class with
     public void customize(Session session) throws Exception {
          session.getDatasourceLogin().getPlatform().setShouldForceFieldNamesToUpperCase(false);
But that doesn't help. Then I checked if it is being set correcly and saw that it is false even before I set it, so the default works as advertised and the var is false.
So i guess this is not the problem. Any idea what can cause it?
here is the class
@Entity
@Table(schema="jpaTABLE")
public class User {
     @Id
     private int ID;
     private String Name;
     private String Password;
     private String Status;
public User() {}
geters...
setters...
here is the code
Query q = em.createQuery("SELECT u FROM User u WHERE u.Name = :name AND u.Password = :password");
here is the error

Table names and column names defined by other languages, not English.

Hi, everyone.
I am wondering if there are any possible problems or any inconvenience
when I define table names and column names by Japanese, not English.
Currently, we are using SQL server 2000 as a db and windows as a operating
system. In the near future, we have the plan to change the database software
and operating system to "Oracle 10g" and "Linux O/S".
I have not experienced the oracle database, which has table names and column
names defined by other languages, not English.
Personally, I would like to use English as table names and column names.
In this case, I might have to provide appropriate reasons.
Are there any possible problems or any "inconvenience" in terms of
system maintenance, development, or something else ?
What could be pros and cons in this case?
Thanks in advance.
Have a nice day.
Best Regards.
Ho.

First you need to make sure your database has character set that support Japanese.
Choosing a Character Set
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14225/ch2charset.htm#i1007681
The main "inconvenience" you will have is if the client doesn't support Japanese or unicode, it will have trouble to access the table.
And say in future after the application been developed, you want to implement the schema in some English environment, you will have hard time to do it.
My point is English tablename and column names doesn't prevent you use it in Japanese environment and save Japanese data but not vice-versa. Hope you understand.
