Getting "ORA-06550: line 1, column 7:\nPLS-00306: wrong number or types of arguments in call" in ASP.NET Web Applications

Hi Experts,

I am getting the following error when I try to retrieve some values in the Data Reader.

{"ORA-06550: line 1, column 7:\nPLS-00306: wrong number or types of arguments in call to 'RETRIEVECURRENTGROUPS'\nORA-06550: line 1, column 7:\nPL/SQL: Statement ignored\n" }

Please help me to get rid of this error. Also Please do get back to me if you need any more details abut this.

thx
Dil.

Make sure the parameters match in numer, direction and data type.

Can you post the code for BuildParameters.

also describe the Oracle Procedure RETRIEVECURRENTGROUPS.

slightwv (䄆 Netminder)

Caught typing.

Still would like the code for BuildParameters.

Did you create t_cursor as a global type or is it created inside the package?

wow.... that's some modular code. Check the XML for that procedure and see what is there as far as parameters.

I am getting the mentioned exception / error here in the following function:

public OracleDataReader GetDataReader

exactly in the following line:
dr = cmd.ExecuteReader();

throwing an exception and the control is going here:
catch ( Exception objError)
                  {
                        //write error to the windows event log
                        WriteToEventLog(objError);
                        throw;
                  }

not returning the data reader.

thx
Dil.

The PLS-00306 message is coming from calling the RETRIEVECURRENTGROUPS procedure.

So whereever you are calling that, there's a problem with the number, datatype or direction of the parameters you are passing it.

dileepav

ASKER

here is the package body:
=====================
PROCEDURE RetrieveCurrentGroups
(i_USER_ID IN VARCHAR2,
CURRENT_GROUPS OUT t_cursor)
IS
BEGIN
OPEN CURRENT_GROUPS FOR
select ugm.User_Group_Id,User_Group_Name
from RDA_SUPPMAINT_USER_GROUPS ug,RDA_SUPPMAINT_USER_GRP_MEMBERS ugm
where ug.USER_GROUP_ID=ugm.USER_GROUP_ID and ugm.USER_ID=UPPER(i_USER_ID)
order by USER_GROUP_NAME;
END RetrieveCurrentGroups;

Here is the body,
PROCEDURE RetrieveCurrentGroups
(i_USER_ID IN VARCHAR2,
CURRENT_GROUPS OUT t_cursor);

Wondering hwat is the mistake with the procedure body and declaration.

XML file is a common one and is working for other procedures.

thx
Dil.

slightwv (䄆 Netminder)

The error message is pretty specific.

Again: Check the declared data types, number of parameters in there and direction for this specific procedure.

There has to be a mis-match between what you are passing Oracle and what it is expecting.
