Problem while displaying all the table names from a MS Access Data Source.

I started preparing a small Database application. I want to display all the Table Names which are in the 'MS Access' Data Source.
I started to executing by "Select * from Tab" as if in SQL.
But i got an error saying that "Not able to resolve Symbol 'Tab' in the query".
Please let me know how can i display all the table Names in the MS Access Dats Source.

Here i am developing the application in Swing using JDBC for accessing the database.
I want to display all the Table names from the data source in a ListBox for easy selection of tables to view their details.

Select data from all the table names in the view

Hi,
"I have some tables with names T_SRI_MMYYYY in my database.
I created a view ,Say "Summary_View" for all the table names
with "T_SRI_%".
Now i want to select data from all the tables in the view
Summary_View.
How can i do that ? Please throw some light on the same?
Thanks and Regards
Srinivas Chebolu

Srinivas,
There are a couple of things that I am unsure of here.
Firstly, does your view definition say something like ...
Select ...
From "T_SRI_%"
If so, it is not valid. Oracle won't allow this.
The second thing is that your naming convention for the
tables suggests to me that each table is the same except
that they store data for different time periods. This would be
a very bad design methodology. You should have a single
table with an extra column to state what period is referred to,
although you can partition it into segments for each period if
appropriate.
Apologies if i am misinterpreting your question, but perhaps
you could post your view definition and table definitions
here.

Cannot display all the tables of the schema!!!

Hi:
I use the oracle sql developer on the windows xp, I found that the tables tab cannot display all the tables of the schema owner, I use the sql "select count(*) from user_tables" I found the result is more than the tab can be display, and I also press the "show more" already.... does anyone can help me ???

Similarly, I have 852 tables owned by the connected user (selected count from user_tables and checked the user tables report which has this many records returned), but when I double-click on the "Show More" and select Show All, I only get approximately 375 tables listed.
It doesn't help that the sorting is different - ie ASF_ comes before ASFB in the connection pane but the other way around in the report.
However, it looks as though the problem is that tables that are not analysed (based on the report data in DATE_LAST_ANALYZED) are not being displayed under the Table node.

Is there a way to view all the table names in a certain schema?

Is there a way to view all the table names in a certain schema?

SELECT table_name FROM user_tablesThat won't do much good given this piece of information:
i am trying to finish a lab for school but i don't know what tables are in my
professor's schema. The appropriate solution is
SELECT table_name
FROM all_tables
WHERE owner = 'PROFESSOR_YAFFLE'
/This will show the names of the tables which Prof. Yaffle has granted to us.

To Get all the Table Names

Hi All
I have nearly 70 procedures in my database.
I want to get all the distinct table names used in the 70 procedures.
Is it possible?
Note:
All the table names are prefixed by schema name like DEVSRC.table_name.
Please advice
Thanks

Hi VT
One doubt.
This query will give the table names of only select stmt used in the procedure
or
List of table names that are with in any DML operations inside the procedure?
Thanks
JoIt will give all the table either used in select or in any DML..

Get the table names from a specified schema name

Can't any one can hlep me how to use OCIDescribeAny() to retrive the list of table names for a given schema name?
I have problem when I connect to the database using syste as usr id. I can't ge the table name form the SCOTT schema.

If I understand you correctly, I don't think OCIDescribeAny() is the way to go.
You can get a list of tables owned by a particular schema by using the following SQL:-
SELECT TABLE_NAME FROM DBA_TABLES WHERE OWNER = 'SCOTT'
Just change the where clause to your needs.

Getting the table names in an MS Access database

Hi,
I am new to JDBC and making a client/server application that updates a MS Access database through jdbc:odbc.
I need to get a list of existing user tables in the db. I have found a great document on the net which has the code, however the code doesn't work. I have tried different ways and looked every where with no success. (link to the doco: http://www-128.ibm.com/developerworks/opensource/library/j-jdbc-objects/)
Here is my dbManager class that handles all db related services in my application. I would appreciate any help I can get as I have exhusted all my avenues.
Thanks

How to display all the files name in same folder inside a JTable?

Currently i am doing an LAN P2P application (similar to KazAa) which is have a function to search files and list out files name after searched found. I am planning to list all the searched file names in JTable. I am having problem to list the files name on a table field. Can anybodu help : ) ? Please

I don't understand what your problem is so I'll just refer you to the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/table.html]How to Use Tables.

Report Column Attributes Does Not Display All the Column Names

Good Morning,
I have an interactive query Select * from table_name. I have to select * since my query returns well over 32k. I have 162 columns in the query. On the screen, all the columns are displayed; however, on the report tab, only about half of the columns are displayed. The rest are cut off. I need to be able to go into these field's attributes. Is this an APEX bug, or am I just missing something.
Regards,
Kelly

Hello Tony,
I can't break them out because APEX is limited to one interactive report per page. There is need to be able to do computations on the data, which interactive reports allows. The data is all statistical.

Kelly

What is the table name from which......

Hi,
when i run a report KE30 - Execute Profitability Report through TCode KE30 in r/3 ( profatibility analysis and profitibility report ) from which table does the report pics the data.
Is the report generation in r/3 is thorugh ABAP only ?
thanks in advance
Janardhan Kumar

Hi Janardhan,
Hope you are fine.
The Tables for COPA Data are CE1xxxx, CE2xxxx,, CE3xxxx, and CE4xxxx,. These tables contain data at different levels.\
COPA tables are defined based on ur operating concern as below -
There is the table CE1xxxx for actual line items (where xxxx = operating concern), which contains all the data at the most detailed level.Holds the line items - Contains Profitablility Segment No, Period, Posting Date, Characteristics & Value fields.
Planned line items are stored in the table CE2xxxx.
The segment level CE3xxxx is set up between the segment table and the line items, thereby making a time-based classification possible. Alongside value fields, the segment level also contains the characteristics record type, planned/actual indicator, version, and period, as well as some additional technical details. Several lines from the segment level are attached to a particular profitability segment (that is, to a line in the segment table). These lines all have the same segment number but relate to different posting periods.
There is also the segment table CE4xxxx, which is located at a higher level. It is used to assign segment numbers to each combination of characteristic values. For the first summarization to be performed, at least the document number and the billing item are hidden.
Basically COPA Reports picks up data by default from Summarization level (if exist) .
The method suggested above may help you find exact table.
Take Care.

Do not Extract from PSA but Access Data Source (for Small Amounts of Data)

Hi Experts,
In the DTP, the above option is available for Full Loads for certain extractors but not for others, particularly, certain HR extractors?
Is there a way to make it available for HR extractors? Is there a setting that needs to be updated in ECC or in BI?
Thank you for your help!

Hi,
There is no special setting for this, Please see the detail description:
Data is not extracted from the PSA for the DataSource; it is requested from the data source directly at DTP runtime.
Use
You use this mode for small data sets and full uploads, for example, small sets of master data. With file source systems, note that the file has to be available on the application server.
Dependencies
You do not have to create an InfoPackage in order to extract data from the source.
Data in the data source is accessed in "direct access mode". This has certain consequences, especially if you are extracting data from SAPI systems:
Data is extracted synchronously. This places a particular demand on the main memory, especially in remote systems.
The SAPI extractors may respond differently than during asynchronous load since they receive information by direct access.
SAPI customer enhancements are not processed. Fields that have been added using the append technology of the DataSource remain empty. The exits RSAP0001, exit_saplrsap_001, exit_saplrsap_002, exit_saplrsap_004 do not run.
If errors occur during processing in BI, you have to extract the data again since the PSA is not available as a buffer. This means that deltas are not possible.
In the DTP, the filter only contains fields that the DataSource allows as selection fields. With an intermediary PSA, you can filter in the DTP by any field.

List all the table names and no of records in DB.

Hi,
How can i write a select query which should give the total tables in the database and the number of records in each table.
Eg: I have 2 table in the database 1. EMP 2. DEPT . EMP table has 14 records and DEPT has 4 records. Then the out put should come like following.
TNAME RecCount
EMP 14
DEPT 4
Regards
Bond.

Also if Table statistics have been gathered(analyze table or DBMS_STATS) then this can also be used:
SQL> create table TEST_ABC
2 (name_ABC varchar2(200));
Table created.
SQL> insert into TEST_ABC
2 values('ABC');
1 row created.
SQL> insert into TEST_ABC
2 values('DEF');
1 row created.
SQL> commit;
Commit complete.
SQL> select table_name, num_rows from all_tables where table_name = 'TEST_ABC';
TABLE_NAME                       NUM_ROWS
TEST_ABC
SQL> analyze table TEST_ABC compute statistics;
Table analyzed.
SQL> select table_name, num_rows from all_tables where table_name = 'TEST_ABC';
TABLE_NAME                       NUM_ROWS
TEST_ABC                                2

Can we find the table name from the form

note:without using the property palette

poelger is right, use GET_BLOCK_PROPERTY either with QUERY_DATA_SOURCE_NAME for the Query-table or with DML_DATA_TARGET_NAME for the DML-target

Want to know the table names as well as number of rows

hi...every one.....i want to explain more in detail to previous thread i have posted.
actually i need to display all the table names and number of rows for each, in a schema(like AP,HR,....)
it's must that i should do it by using a stored procedure.
so the best way for this would be by using cursor and loop.
so please help me in solving this question.

How to find out all table names which has a particular data

Hi,
How could i get all the table names from a database(for a schema) which has data 'KST6490' in one of the fileds in the table.There are many tables with this
data. Data type is Varchar2. Thanks.

One approach would be to create a procedure which retrieves the name of all tables in the schema using the user_tables view. Then use the user_tab_columns view to get all the column names and types. If the type is varchar2, then dynamically create a sql statement which runs a query on that column using the value which you are looking for. You would need two cursor loops for this approach: one for tables and one for columns. This approach requires good PL/SQL programming skills.
Alternately, many query tools, such as Golden, provide a search capability on query results. Just do a select * from the table and search on the results. This would need to be done table by table and the results would have to fit in the memory available to the tool.
Alternately, you can write table contents to a text file on the a server and then search the text file using operating system tools such as grep. This would require good OS scripting skills.
