Using table function in JDBC
Hi All,
im Oracle 9i R2 :
there are package with table function and JDBC client .
In client code :
Statement st = con.createStatement() ;
ResultSet rs = st.executeQuery("select * from table(pkg.func)") ;
while (rs.next())
System.out.println(rs.getString(1)) ;
- and that not work ...
What is wrong ? :)
With best regards, Slava
Can you define "not work" here... Do you get an error? If so, what is the error number you are getting (ORA-xxxxx)?

Ora-600 using table function over db link
Hi,
I have a table function n my target schema (OWB 9.2.0.4 on Oracle 9.2.0.5) with the following signature:
function uii_get_exchange_data_tf(
p_input_values in sys_refcursor
) return uii_exchange_table_t pipelined
When I try to use this with a remote table over a db link, e.g.:
=============
select * from table(uii_get_exchange_data_tf(cursor (select sub_zone || '/' || exch_grp_cd exchange_id,
exch_name exchange_name FROM cds_exchange_test@uiid1@uiidraconn order by exchange_id)))
==============
I get this:
================
ORA-00600: internal error code, arguments: [kokbnp2], [942], [], [], [], [], [],
ORA-06512: at "UII_ODS_OWNER_DEV.UII_GET_EXCHANGE_DATA_TF", line 21
=================
However, if I create a local view with the same remote select like this:
===================
CREATE OR REPLACE FORCE VIEW UII_CDS_EXCHANGE_RV
AS SELECT sub_zone || '/' || exch_grp_cd exchange_id,
exch_name exchange_name
FROM cds_css_exch_detail@uiid1@uiidraconn;
====================
Then everything works fine.
Can someone help ? I'm sure I'm dooing something silly, since so many people seem to be using table functions from OWB just fine; but I can't figure out what :-(
Thanks in advance.

Which flavor of Disco (Plus, Desktop, Viewer)?
Standars EUL or Apps EUL?
Can you post the code for the calculation?
ORA-600 errors, as you mentioned, are internal, and may require opening a dialog with Oracle support. Then again, it could be something else in the calculation that is causing the sky to fall. -
Does using TABLE FUNCTIONS degrades performance
Hi,
I am using a TABLE Function TABLE(TABLEA)
I am using a SQL Statement where I am joing TABLE FUNCTION :TABLE(TABLEA) and Normal table:TABLEB
i.e
SELECT CODE,SUD FROM TABLEB,TABLE(TABLEA)
WHERE CODE=CODE1 (CODE1 is a Object Type variable).user598986 wrote:

i.e
SELECT CODE,SUD FROM TABLEB,TABLE(TABLEA)
WHERE CODE=CODE1 (CODE1 is a Object Type variable).One particular issue with table functions and joins is that the optimizer doesn't have a clue about the cardinality, i.e. the number of rows returned by the table function and therefore applies defaults which might be way off. If you somehow know roughly how many rows are going to be returned (may be a quite constant number of rows or your process know the number of rows in a collection etc.) then you can help the optimizer by using the (undocumented) "CARDINALITY" hint, e.g.
SELECT /*+ CARDINALITY (A, 100) */ CODE,SUD FROM TABLEB B,TABLE(TABLEA) A...
tells the optimizer that the table function is going to return 100 rows. Note the usage of the alias in the hint.
But bear in mind that this only helps partially, some other basic information like column statistics are still missing and therefore the estimates of the optimizer still might be inaccurate.

For some reports, I cannot precompute some values and I need user input. For this I want to use table funcitons but I need to be able to get paramter values from user.

How to use todate function in JDBC adapter
Hi All,
How can we use the todate function to update a date field in Oracle database. I am getting a
java.sql.SQLException: ORA-01858: a non-numeric character was found where a numeric was expected
Exception, when I am mapping the date fields with to_date('03/28/2009 18/43/19','MM/DD/YYYY HH24/MI/SS').
Thanks,
YomeshThe following is standard SAP document regarding this attribute, this attribute used to compose your SQL clause for string or non-string, for string, you need to put the "YES". in your case, you need to set set the value "NO"
so create an attribute, pass a constant value "NO" to it, that is it.
hasQuot= YES|NO During construction of the WHERE condition of the SQL statement, the table column type determines whether the default is to set the values in quotation marks (text column types) or not (numerical column types). In a few cases (for example, when using functions), it may be necessary to override this. This attribute enables you to do this. If YES, quotation marks are always set round the values for which this attribute is set in the SQL syntax. If NO, quotation marks are never set. Only use this attribute in individual cases.
Regards.

Question regarding cursor variables, while using table functions
Hi,
I created a procedure and when i'm try'g to call it. now i'm getting this error.
CREATE OR REPLACE TYPE TAB_EMP_REC IS OBJECT(

EMP_NAME VARCHAR2(30));
CREATE OR REPLACE TYPE T_EMP_TMP IS TABLE OF TAB_EMP_REC ;

Now i'm getting an error PLS-00362: invalid cursor return type; 'TAB_EMP_REC' must be a record type.
My question is i already declared it as a database object. What do i need to do ?
thank youbut t_emp(1) := TAB_EMP_REC(p_input, 'jai');
is correct, since.. i'm passing a record into t_emp(1)(this is the first column in this table)No it is not, since TAB_EMP_REC is just an object, when used as a collection, it can be a VARRAY, a PL/SQL table(associative array), nested table etc. As mentioned in my earlier post, if you want to use a collection of the same structure (with subscript n, as you have done here), then you need to declare a collection of type TAB_EMP_REC.In this case you have already declared a table of type TAB_EMP_REC - +CREATE OR REPLACE TYPE T_EMP_TMP IS TABLE Also, t_emp is of type T_EMP_TMP - T_EMp T_EMP_TMP := T_EMP_TMP( );*
As for the error you are getting, try changing to -
t_emp := T_EMP_TMP(TAB_EMP_REC(p_input, 'jai'));*
Note : Not Tested. -
Internal Error while using Table Functions

It gives this error
ORA-00600: internal error code, arguments: [17274], [4], [], [], [], [], [], []
Can anyone help me out... Any help will be appreciated
[email protected]1. Have the screen open where you have the Shift F2, you can manually run the query of the formatted search, it will sometimes give you more meaningful message.
Eg:
You have a formatted search query 'Query 1' which is saved in Tools> User Query> Query 1 attached to field DocTotal.
So, what you do is, instead of pressing Shift F2, you go to tools > User Query.> Query 1 to run it.
2. Another thing could be the field you used in the formula do not have the focus when you run it.
Eg: you use $[4.0.0] in the query.
When you press Shift F2, the field represents $[$4.0.0] do not have focus. -
How to use the Table Function defined in package in OWB?
Hi,
I defined a table function in a package. I am trying to use that in owb using Table function operator. But I came to know that, owb R1 supports only standalone table functions.
Is there any other way to use the table function defined in a package. As like we create synonyms for functions, is there any other way to do this.
I tryed to create synonyms, it is created. But it is showing compilation error. Finally I found that, we can't create synonyms for functions which are defined in packages.
Any one can explain it, how to resolve this problem.
Thank you,
Regards
Gowtham Sen.Hi Marcos,
Thank you for reply.
OWB R1 supports stand alone table functions. Here what I mean is, the table fucntion which is not inculded in any package is a stand alone table function.
for example say sample_tbl_fn is a table function. It is defined as a function.It is a stand alone function. We call this fucntion as "samp_tbl_fn()";
For exampe say sample_pkg is a package. say a function is defined in a package.
then we call that function as sample_pkg.functionname(); This is not a stand alone function.
I hope you understand it.
owb supports stand alone functions.
Here I would like to know, is there any other way to use the functions which are defined in package. While I am trying to use those functions (which are defined in package -- giving the name as packagename.functionname) it is throwing an error "Invalid object name."
Here I would like know, is there any other way to use the table functions which are defined in a package.
Thank you,
Regards,

Table function on a collection in Dynamic SQL
Hello,
I am trying to create a refcursor by selecting from a collection using table function.
If I use the Select statement the query executes, but if I put the Select statement in a string
the collection variable does not get resolved. The resaon I am putiing it in a string is because the
WHERE clause will be passed a parameter. The code below is an anonymous block but will be changed to a
procedure once I get it to work.
I have tried many different ways but was unsuccessful.

TABLE function to simulate parameterized view
Hi all,
Since view can not have parameters, I tried to used stored procedure to return ref cursor then used TABLE function in select statement to simulate a view with parameters, since it's easy to pass parameters to a stored procedure.
The idea is like this
function foo (p1 int, p2 int)
return sys_ref_cursor
c sys_ref_cursor -- sorry, i forgot the buildin ref cursor name, just used
this as pseudo code
is
open c for select * from table_a where col1=:p1 and col2=p2 using p1, p2;
return c;
end;
select * from table(foo(1,2)) does not work, I know that I can iterate throught
the cursor and pipe it out to a SQL type in function foo, then use TABLE
function in SELECT statement. However, it seems so much coding work. Is it the
only way or do you have better idea?
Thanks in advance.It is just not correct that you cannot parameterize views.
Nicolas gave you a link above which has an example using a context.
Even before Oracle supported contexts you could have parameterize views using package variables.

2 function get_job return emp.job%type;
