How to retreive table names ?

Hi Gurus,
Having query using DatabaseMetaData..
I am trying to get Tables names from my database using code below..
try{
String[] type = {"TABLE"};
con2 = MyConnection.getConnection();
DatabaseMetaData metaData = con2.getMetaData();
ResultSet rs = metaData.getTables(null, null, "%", type);
System.out.println("Table Names:");
while (rs.next())
ResultSetMetaData rm = rs.getMetaData();
String s = rs.getString("TABLE_NAME");
System.out.println(s);
This code works fine and it gives me table names.. BUT my que is it retreives ALL table names including some system tables. (it gives me tables, for example, like: DR$NUMBER_SEQUENCE).
I just want to retreive ONLY table-names that I have created.
Is there any other override available for getTable() I can use ? OR any other solution ?
Thanks in advance!

You see where you have this?
ResultSet rs = metaData.getTables(null, null, "%", type);Specifically where you have the nulls and the %?
You can pass actually useful things in there if you wanted and that might help. Consult the Javadoc API for more information on this.

  • How get all table name from database

    hi master
    sir
    how get all table name from database

    The big question is 'why'.
    Selecting from view 'dba_tables' will indeed give the list of all tables in the database, but that includes the dictionary tables and the internal tables, and many others that are probably not of interet to a person who needs to ask this question. Besides, the dba_tables view requires access to a DBA account.
    There are several other views: "user_tables" will list all the tables in this user's schema; and "all_tables" will list all the tables this user can access in some way.
    The above do not, of course, include any information about synonyms, sequences, views, indexes and so on.
    The correct answer and the meaningful answer may be two different things.

  • How to find table name for the fields from Standard Extractor in CRM system

    How to find table name of fields from the standard extractor in CRM system ?
    e.g. We use LBWE TCode in R/3 system to find table name for the field from Extractor VCSCL(e.g.).
    Likewise is there any way to find table name for the fields from Standard extractor like 0CRM_LEAD_I.

    Hi ,
    Please find the link below for understanding BW CRM analysis.
    http://help.sap.com/bp_biv135/html/bw.htm
    activate the CRM DSs by scenario:
    1) Activate the application component hierarchy (tcode RSA9). Changes made to the application component hierarchy in the CRM system can be transferred to the BW using the "Edit Application Component Hierarchy" (SBIW - Postprocessing of DataSources).
    SAP Note 434886 must be implemented in CRM 3.0 before the application component hierarchy is activated.
    2) Activate the Business Content DataSources (tcode RSA5).
    Select/enter the application component and choose Execute (F8).
    To compare the shipped and active versions, choose the 'Select Delta' pushbutton. If there is no active version of the DataSource, it is selected automatically.
    To activate the shipped version, choose the 'Transfer DataSources' pushbutton.
    3) Management of the versions of the BW-Adapter metadata (tcode BWA5). All DataSources are displayed that are managed by the BW Adapter.
    As in transaction RSA5 (Service API Metadata Activation), the 'Select Delta' function can be used to select the inactive DataSources or compare shipped and active versions.
    You can also go directly to the screen for maintaining DataSources that are managed by the BW Adapter.
    The 'Compare Version' function makes a detailed comparison of the shipped and active versions.
    All BW-Adapter metadata is considered when versions are compared:
    Header information (Table SMOXHEAD)
    Mapping information (Table SMOXRELP)
    Global selection conditions (Table SMOXGSEL)
    Attribute key fields (Table SMOXAFLD)
    Hope this helps.

  • How to Concatenate Table name and Where condition at runtime

    I am passing parameter as User and Zone to Stored Procedure.How to concatenate Table Name
    and WHERE CONDITION in SQL Statement.i have different type of users and zones.

    Hi !
    declare
      cur sys_refcursor;
      r emp%rowtype;
      v_sql varchar2(512);
    begin
    -- do your logic here
      v_sql := 'select * from emp';
      open cur for v_sql;
      loop
        fetch cur into r;
        exit when cur%notfound;
        dbms_output.put_line(r.ename);
      end loop;
      close cur;
    end;In this example you can see how can be done this with cursor vars .. You should concatenate v_sql string according to your requirements.
    But as in further posts has already been mentioned , be carefull at publishing such kind of procedures and think on security.
    Also when you want dynamicaly change from clause , you should consider using different records to accept data ? Maybe all your tables has the same structure and then this problem will be smaller.

  • How to retrive table names with Java?

    Hello!
    If I connect to my Oracle Database 10g Express Edition Instance with some Java code and I run the following code:

                   while( resultSet.next() )
                        String tableName = resultSet.getString(3);
                        System.out.println(tableName);
    I get loads of different names of tables beside those that belongs to my user like:

    DR$POLICY_TAB
    ARTICLES

    Does any one understand how to access just these table names that is created with my user?

    Yes you are right I now understand that this is the wrong forum.
    So I posted the "same question" at:

    How ever I seems to have problem with the schema name parameter any way.

  • How to find table name(s) in a dynamic query

    In one of our (9iAS PORTAL)applications, any user can able to run their query statment and get output. All queries will be executed as dynamic SQL thru' a common shema/user who has 'SELECT' privilege on all tables but all users don't have this privilege on all tables. Now, before executing any query I need to find out what are the table name(s) used in this query to check the privilege for the respective user. How do I extract all table names being used in a dynamic query?.
    Thanks
    -Krishnamurthy

    I guess that his users log in to application first, then application uses one account to log in to database, so application are not direct database user since all users share the same account to database. If so, when a user lgins in, you may write it down from application to a database audit table, and you need to write down the dynamic query to the database audit table too, then you may query that audit table to find out. up to here, it looks that your application has to do more to assign what role to a user running the application, since database does not know what user is assessing it.

  • How user variable table names in select statement

    Dear all,
    I have three table gp1,gp2,g3. i want user variable table in sql query
    for example at oracle forms have a list table showing table names gp1,gp2,gp3
    at form i want user this query
    select gpno from :table where gpno=120;
    how i can specify table name Dynamicly in select query
    Thanks

    Forms_DDL is a one-way street: You can only pass DDL commands TO the database; you cannot get data back using Forms_DDL.
    Exec_SQL is the Forms package that enables dynamic sql within a form. But to retrieve data, you have to make a Exec_SQL call for every column in every row. So it is not a good thing to use, either.
    The ref cursor method should work. You could also retrieve the data into a record group using populate_group_with_query -- it also enables dynamic data retrieval.
    But if you already know you have three distinct tables and you know their names, I would keep it simple and just write three sql select statements.

    I want to use table name dynamically means at runtime i want to pass table name.
    I can do this by lexical parameter in main query.
    But my problem is that i want to crate new format trigger or new function that use 1 cursor in which that lexical parameter : table name is used.
    so how to do that?
    i can not use that lexical parameter it is giving error.
    please help me how to do that.

    Call a database function which you pass the lexical parameter. Then in the database function you use dynamic sql or the execute immediate option to build the SQL string.
    Return the information from this function to build your business logic on in your format trigger.
