Do you have the Toad Debugger? Thats the extra cost option which you get for free in OracleSqlDeveloper.
If you have the ToadDebugger, Read the Manual
If not , download OracleSqlDeveloper and use it. It's free, and written by Oracle.

I can't execute oracle functions with c#. i'm using oracle 9i version.

i have a problem trying to execute an oracle function with c#.net. The Oracle version i'm using is Oracle 9i.
This is the function definition: (it's defined and working right because i have tryed it with SQLWorksheet)
CREATE OR REPLACE Function NRegistros return integer is
Numero integer(4);
begin
select count(*) into Numero from singles;
return Numero;
END NRegistros;
But with c#.Net i can't acces it because i get an error: "this is not a procedure or is not defined". And i think the code is right. In fact in the same code you can see that i'm using an stored procedure and i have not problems. But with the function i have problems. Is it possible that "OracleClient" can't work with Oracle9i functions??. This is the code:
OracleParameter Parametro = new OracleParameter("Name", OracleType.VarChar,10);
OracleParameter ParametroFuncion = new OracleParameter("Retorno", OracleType.Int32, 4);
Parametro.Direction = ParameterDirection.Output;
ParametroFuncion.Direction = ParameterDirection.ReturnValue;
OracleConnection Conexion = new OracleConnection("Data Source=DISCOS;User Id=SYSTEM;Password=a0000;");
Conexion.Open();
OracleCommand Todos = new OracleCommand();
OracleCommand Procedimiento = new OracleCommand();
OracleCommand Funcion = new OracleCommand();
Todos.Connection = Conexion;
Todos.CommandType = CommandType.Text;
Todos.CommandText="select * from singles";
Procedimiento.Connection = Conexion;
Procedimiento.CommandType = CommandType.StoredProcedure;
Procedimiento.CommandText = "Procedimiento";
Procedimiento.Parameters.Add(Parametro);
Funcion.Connection = Conexion;
Funcion.CommandType = CommandType.StoredProcedure;
Funcion.CommandText = "NRegistros";
OracleDataReader Lector = Todos.ExecuteReader();
BindingSource Discos = new BindingSource();
Discos.DataSource = Lector;
dgvSingles.DataSource = Discos;
Procedimiento.ExecuteNonQuery();
Funcion.ExecuteNonQuery();
lblRegistroProcedimiento.Text = Procedimiento.Parameters["Name"].Value.ToString();
lblNregistros.Text=Funcion.Parameters["Retorno"].Value.ToString();
Conexion.Close();

Install Oracle 10g with Toad 9.1

Hi All,
I am a novice in database(SQL,PLSQL) programming and hence want to learn and practise very deeply in detail for which i want to install Oracle 10g client with Toad 9.1.So need your advise on the process.
(a)Do i need to download entire Oracle Enterprise Edition Installation for Vista? I have read in one of the forums that downloading only the Oracle Client is enough?
Can you please advise me?
(b)I already have the TOAD 9.1 setup with me which i can install.But,i do not know that how will i use TOAD interface and connect to the oracle database.
(c)Also,any sample script/database with some tables that i can use for learning complex SQL query writing would be very helpful.In brief-any project that i can work on in building all the requirements by writing SQL which simulates real time scenarios of SQL development.
Please help me ,i am struggling.
Thanks
Dev

Hi all,
Thanks a lot for all your inputs.Its very useful and presently I am following the steps suggested.
I had another doubt with respect to this.While attending a oracle course,the instructor had told about an installation option of installing oracle 10g on Linux using VMware/virtual -i am sorry i am not sure about it.
So,can you please give your inputs about this process as I dont know about how to setup?
(a)What are the tools that i will need to build a virtual machine in my present computer with Linux as the OS?
And,what are the steps we need to do ?
(b)How do i use a vitual machine if i install it? I mean how will it work?
(c)Then,at last how do i install Oracle with Linux on that?
Please help me with some more inputs

Oracle functions with PowerPivot

Hi All,
I have a requirement of building reports using Oracle functions in PowerPivot.
I have tried using Table Import Wizard and Command Type=StoredProcedure in th ePowerPivot.
Any help will be appreciated.

Free oracle client with Toad?

Hi,
I have licensed vesion of Toad available. Do I need to purchase oracle client - or is there a free version of oracle client that can work with toad without any cost? My database is Oracle 10.2.0.4 on Solaris 10. I read about instant client but I don't know if that can work with toad and I have no experience on it.
Thanks,
Edited by: orausern on Jun 28, 2011 10:02 AM

Licensing questions should really be directed to whoever deals with Oracle licensing in your organization or to your Oracle Sales rep. The answer may depend on a variety of factors including the country you are in, when you purchased licenses from Oracle, what sort of licensing agreement you have, special stipulations that were negotiated in your licensing agreement, etc. If there is an audit, explaining that you relied on some random guy on the internet with a playing card logo next to his name for legal advice is a career limiting maneuver.
In general, Oracle does not license client machines. The database is licensed either by the number of users allowed to connect (not simultaneous users or Oracle database users but the number of human beings that are allowed to connect to the database via some application) or by the number of processors in the database server. So you generally don't need to license anything to install the Oracle client assuming that you as a human are licensed to connect to the database.

Oracle Function with out parameters

Hi, I'm trying to access a stored function on an oracle server with 2 out parameters, 2 in parameters and an out ref cursor.
PL/SQL looks like this
nStatusCode OUT INTEGER,
sStatusMsg OUT VARCHAR2,
sUsrNr IN VARCHAR2,
sPassword IN VARCHAR2,
crsReturn OUT pck_cursor.retRecordSet
I drag the function onto dataset designer and it successfully maps the results to the datatable, it maps datatypes for first out parameters to decimal and string.
the method genearated for fill by looks like (out decimal?,out string,string, string, out object)
problem is, everytime i try to call this function it gives me casting exceptions for the first 2 out parameters, for the decimal it's not specified in more detail. for the other one it says there was an exception casting from OracleString to string. If I change the PL/SQL function to leave the first 2 out parameters away it works fine. Do I manually need to change the TableAdapter definitions??

Hi,
I think I found the problem but not a good solution. It seems to be a problem with auto code generation for TableAdapters in the Dataset wizard. In the Parameter Definition for the Command I set DbType.Decimal and DbType.Sting for the SqlDbtype Property of the out params. The GetData and Fill Method is generated with Fill(out decimal? out1, out string out2). When I look in the generated code ith first sets the SqlDbtype as written but after this also the OracleDbtype to OracleDbType.Decimal and OracleDbType.Varchar2. The casting these types before returning the throws the exception. Any idea how to change this behavior?

Executing a oracle function with parameters ...

</cfquery>
<cfoutput> #getvalcount.sf_drop_validate_and_count# </cfoutput>
</td>
</tr>
but I'm receiving the error from oracle telling: illegal zero-length identifier
My question is...
IS there a way to pass the parameter #name# to this function sf_drop_validate_and_count ? or should I work with parameters to a stored procedure?
Thanks in advance
Regards
Alex

Hi ALL,
Just to inform you that I've found a solution when you need to apply variables as a parameter:
preserveSingleQuotes(vFileName)
preserveSingleQuotes function will keep the string like this 'dadsadsad' and so, you can use it inside your functions, procedures, etc..
Thanks for all the reponses I've received.
Best regards

How to use LIKE function with a parameter in Oracle REPORT builder??

how could i use parameter inside a LIKE function in Oracle reports builder?
it works in SQL plus, but not in report builder!!
Example:
select code,desc from item_master where desc
like '%&give_desc%'; ---works in SQL
like '%:give_desc%' ---doesn't work in report builder!!

Hi Renil,
You will need to use the wildcard character (%) and the concatenation character (||) to join to your user parameter.
i.e. like '%'||:give_desc||'%'

Union dataset from oracle function with dataset from a postgres function

I retrieve two sets of data,
one from an oracle database using Command_1 select * from table(functionname(param1, param2))
one from postgres database using Command_2 select * from functionname(param1, param2)
i can join the two tables (Command_1 and Command_2) with database expert > links
I would like to know if it is possible to UNION the two sets

Don't think so.
I have only done that by linking from Oracle to the other database and forming the union in Oracle.

Oracle Function with a select into problem

Here is one that I cannot figure out. I'm trying to select the median of a set of events in a purchase qty. I have the selects working in SQL. It returns the correct answer for several sets of test data. However, when I put this into a function to be able to call during more complex queries it doesn't work. I've tested the function several different ways and it's looking like the select median into v_median2... is not working. Please help!
Here is the code... When this is run what ever is in v_plant is returned. IE: If you pass 1122 into with getmedian('4567','12345678-0001') this returns 4567 at the output. I've bypassed the v_plant and v_material in the select part below and it still output 4567.
If you run the select (with test data put in place of v_plant and v_material in a sqlplus window without the INTO v_median2) it would return a 12.
If you run this function as is it would return 4567.
Here is the output from the dbms_output tests.
4567
12345678-0001
4567
12345678-0001
4567
WHY?
CREATE OR REPLACE FUNCTION getmedian(v_plant IN VARCHAR2, v_material IN VARCHAR2)
RETURN NUMBER
AS
v_median2 NUMBER;
BEGIN
DBMS_OUTPUT.PUT_LINE(v_plant);
DBMS_OUTPUT.PUT_LINE(v_material);
SELECT MEDIAN INTO v_median2
FROM (SELECT ROWNUM as rownums,MEDIAN
FROM (SELECT abs(quantity_in_unit_entry) AS MEDIAN
FROM tbl_transactions
WHERE plant = v_plant
AND material = v_material
AND movement_type IN ('961','261','201')
ORDER BY quantity_in_unit_entry DESC))
WHERE ROWNUMs = ( select round(COUNT(1)/2,0) AS TOTAL2
from tbl_transactions t
WHERE plant = v_plant
AND material = v_material
AND t.movement_type IN ('961','261','201'));
DBMS_OUTPUT.PUT_LINE(v_plant);
DBMS_OUTPUT.PUT_LINE(v_material);
DBMS_OUTPUT.PUT_LINE(v_median2);
RETURN v_median2;
END;

It looks like another one of those cases where the pl/sql engine doesn't yet handle everything that the sql engine does. The usual solution is to execute the part that only works in sql dynamically. Try this:
CREATE OR REPLACE FUNCTION getmedian
(v_plant    IN VARCHAR2,
   v_material IN VARCHAR2)
RETURN         NUMBER
AS
v_rownums      NUMBER          := 0;
v_sql          VARCHAR2 (4000) := NULL;
v_median2      NUMBER          := 0;
BEGIN
SELECT ROUND (COUNT (1) / 2, 0)
INTO   v_rownums
FROM   tbl_transactions
WHERE plant = v_plant
AND    material = v_material
AND    movement_type IN
         ('961', '261', '201');
v_sql :=
'SELECT median
   FROM   (SELECT ROWNUM AS rownums,
                  median
           FROM   (SELECT   ABS (quantity_in_unit_entry)
                                AS median
                   FROM     tbl_transactions
                   WHERE    plant = :v_plant
                   AND      material = :v_material
                   AND      movement_type IN
                            (''961'', ''261'', ''201'')
                   ORDER BY quantity_in_unit_entry DESC))
   WHERE rownums = :v_rownums';
EXECUTE IMMEDIATE v_sql INTO v_median2
USING v_plant, v_material, v_rownums;
RETURN v_median2;
END getmedian;

Oracle 11 can not connect with toad

Hello to all,
I just installed oracle 11 on my pc running vista. I can connect to the data base using sqlplus but not with Toad (version 8.6.1). I enter user and password and nothing happens. Not even an error message. I was using previously oracle 10g with toad and never had a problem.
Can anybody tell me how to make toad work with oracle 11?

hi,
thanks for you answer. Since i was experiencing problems, i just rollbacked to version 10g but i'll try your suggestion later.
Thanks again.

Help - Oracle function w/RETURN VIEW_NAME%ROWTYPE

I have a fairly complex Oracle function with a signature like this:
FUNCTION get_some_data
in_param_one VARCHAR2
, in_param_two VARCHAR2
)RETURN VIEW_NAME%ROWTYPE
(The internal logic of the function is such that it will return at most one row.)
I have sample code from MSDN that outlines calling functions in .Net, like this:
// create the command for the function
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = "GET_EMPLOYEE_EMAIL";
cmd.CommandType = CommandType.StoredProcedure;
// add the parameters, including the return parameter to retrieve
// the return value
cmd.Parameters.Add("p_employee_id", OracleType.Number).Value = 101;
cmd.Parameters.Add("p_email", OracleType.VarChar, 25).Direction =
ParameterDirection.ReturnValue;
// execute the function
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
// output the result
Console.WriteLine("Email address is: " + cmd.Parameters["p_email"].Value);
I don't see an available OracleType to fit the '...%ROWTYPE' return value.
I think the Oracle code is doing inferred 'table inlining' but it may, instead, be using an inferred refcursor (clearly I'm no DBA). Everything I've been able to find online when googling for how to handle this in .Net doesn't seem to match this situation.
How can I call this function and get the data back in C#? Please note that I don't have the authority to modify the package to make it explicitly return a refcursor.
Thank you for any light you can shed!

Here's a "quick and dirty" example using the HR sample schema that I think might be enough to get you going...

open emp_cur;
fetch emp_cur into emp_rec;
close emp_cur;
return emp_rec;

Oracle Spatial functionality with WFS

Hi all
My first post here so be gentle on me ;-)
This may be an obvious question but here goes ...
When using a WFS client can you access the full SDO_... SQL functions within Oracle Spatial? I've had a read of the WFS spec and it is all a bit vague on how the queries get passed through to the data store.
Also with the WFS locking, is this done at the web server level? If so how would that impact on any direct access to the database? A bit dangerous??
Appreciate any advice on WFS implemtations with a 9i back end. I want to retain the full native Oracle functionality and still deploy via WFS ... a pipe dream??
Thanks
Richard

Thanks for your response Andreas
Sorry, perhaps I wasn't clear, I realise the WFS client will never directly access the data source, that it is the WFS server that makes the request to the data store, not the client, but can the call be passed through to Oracle as native SQL?
I think I found the answer in the OGC Filter Encoding Imp Spec where it desribes in great detail the optional filter component of a WFS request. It desribes the CQL filter operators that include some spatial operators. These could, I understand, be translated from CGL and Feature based schema to SQL (in GML?) and relational based schema.
While I don't think at first glance that the spatial operators in CQL match all the Oracle SDO_ functions they probably go far enough for most normal users.
Am I on the right track?
Does anyone know of any work that has been done in this filter translation to SQL and if it has been implemented successfully anywhere.
I think the locks would still pose a problem, but that's for another day :-)
Thanks
Richard
