It is common to have pages with filters in most asp.net application (usually have 5 or more criterias, EX: filtr by:lastname, firstname, date, etc..).
Mostly dealing with TSQL (SQL Server 2000/2005) . I would deal with criteria(s) in my procedures, for example:
PARAMETERS Param1 VARCHAR(32), Param2 INT;
SELECT columns FROM table WHERE
([Param1] IS NULL OR column1 = [Param1])
AND
([Param2] IS NULL OR column2 = [Param2])
Can someone show me how optional parameters are dealt PL/SQL, Thanks
For example:
create or replace procedure optPar(a in number, b in number := null, c number := 999) is
begin
dbms_output.put_line(a || ', ' || b || ', ' || c);
end;
The procedure needs the a parameter:
SQL> exec optPar();
BEGIN optPar(); END;
*
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'OPTPAR'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
You can omit b, c:
SQL> exec optPar(1);
1, , 999
PL/SQL procedure successfully completed.
SQL> exec optPar(1, 2);
1, 2, 999
PL/SQL procedure successfully completed.
SQL> exec optPar(1, 2, 3);
1, 2, 3
PL/SQL procedure successfully completed.
In this case, explicitly passing parameters is even more important then with no optional parameters, to easily understand which value you are giving to each parameter:
SQL> exec optPar( a=> 1, c=> 3);
1, , 3
PL/SQL procedure successfully completed.

I try to write select procedure in oracle.but it compile success, when I try to execute it given error.

The cause of the error is:
the procedure contains 3 parameters:
2 of them are IN - you provided their values
1 of them is OUT - you didn't provide it and got the error
Here's what you should have done: as the 3rd parameter is OUT, you'll have to DECLARE it:
SQL> declare
2 l_out varchar2(20);
3 begin
4 retrieve_decrypt(5, 'creditcardno', l_out);
5 end;

EXEC you used is a SQL*Plus command so it might not work everywhere; DECLARE-BEGIN-END block will so I'd suggest you use it.
Alternatively, in SQL*Plus, it could be rewritten as
SQL> var l_out varchar2
SQL>
SQL> exec retrieve_decrypt(5, 'creditcardno', :l_out);
PL/SQL procedure successfully completed.
SQL>
but - once again - you'd better use DECLARE-BEGIN-END PL/SQL block.
The initial error is:
wrong number or types of arguments in call to 'RETRIEVE_DECRYPT'
The procedure requires 3 parameters. You are only passing 2 (or apparently only 1, in the attempt that generated the error message shown).
Why do you also see the message "Usually a PL/SQL compilation error"? The EXEC command in SQLPlus creates a PL/SQL block containing the text you provide, and sends that to Oracle for execution. Oracle attempts to compile that PL/SQL block (just like it compiles the procedure when you create it). In this case, the compilation fails because of the mismatch in the number of arguments.
I have procedure with params:
procedure GetReceipt(iPaymentID in number
,oReceipt out sys_refcursor
,oReceiptItems out sys_refcursor);
I try to run this my anonymous block:
SET serveroutput on;
DECLARE
oReceipt sys_refcursor;
oReceiptItems sys_refcursor;
BEGIN
API.MOD.GetReceipt(4209735, oReceipt, oReceiptItems);
dbms_output.put_line('oReceipt: ' || oReceipt);
dbms_output.put_line('oReceiptItems: ' || oReceiptItems);
END;
I get this error:

How call this procedure? Where my mistake?
You can use bind variables to store the cursors and PRINT to print them:
VARIABLE receipt REFCURSOR;
VARIABLE receiptitems REFCURSOR;
BEGIN
API.MOD.GetReceipt(4209735, :receipt, :receiptitems);
END;
/
PRINT receipt;
PRINT receiptitems;
Where my mistake?
A cursor is a named pointer to a private SQL area that stores information for processing a specific query. It does not make sense to concatenate a pointer to something internal to the database with a string.
If you want to display the values in your PL/SQL block then you will need to loop through each record of the cursor and get the individual column values for that record and then use DBMS_OUTPUT to display them:
SET serveroutput on;
DECLARE
oReceipt sys_refcursor;
oReceiptItems sys_refcursor;
col1 RECEIPT_TABLE.COL1%TYPE; -- Same data type as COL1 of the RECEIPT_TABLE table
col2 RECEIPT_TABLE.COL2%TYPE; -- Same data type as COL2 of the RECEIPT_TABLE table
col3 RECEIPT_TABLE.COL3%TYPE; -- Same data type as COL3 of the RECEIPT_TABLE table
rec RECEIPT_ITEMS_TABLE%ROWTYPE; -- Assumes the cursor is returning all the columns from
-- the RECEIPT_ITEMS_TABLE table
BEGIN
API.MOD.GetReceipt(4209735, oReceipt, oReceiptItems);
dbms_output.put_line('oReceipt:');
LOOP
FETCH oReceipt INTO col1, col2, col3; -- Store the values from the current record
EXIT WHEN oReceipt%NOTFOUND; -- Stop if the end of the cursor has been reached
DBMS_OUTPUT.PUT_LINE( col1 || ' ' || col2 || ' ' || col3 );
-- Output the values
END LOOP;
dbms_output.put_line('oReceiptItems:');
LOOP
FETCH oReceiptItems INTO rec; -- Fetch the current row into a record
EXIT WHEN oReceipt%NOTFOUND;
DBMS_OUTPUT.PUT_LINE( rec.colA || ' ' || rec.colB || ' ' || rec.colC );
END LOOP;
END;
/
sys_refcursor returns record set, may not be just a column.
So, you can not message it as a classical string with dbms_output.put_line. There should exists some columns(sub-components) of this argument in your routine like oReceiptItems.col_a or oReceiptItems.col_b so that you could message by these columns as strings with dbms_output.put_line.
Using Oracle SQL Developer I created a simple procedure. The procedure compiles successfully, but when I type the command:
execute CMPPROJECTPROCSELECT();
BEGIN CMPPROJECTPROCSELECT(); END;
I get the following errors:
Error starting at line : 1 in command -

Please help me to solve this. I know it's a small error. Also I have specified the data types, declarations of names correctly.
My procedure code is
CREATE OR REPLACE PROCEDURE CMPPROJECTPROCSELECT(
p_projectname IN VARCHAR2,
p_description OUT VARCHAR2)
IS
BEGIN
SELECT DESCRIPTION
INTO p_description
FROM CMPPROJECT
WHERE PROJECTNAME = p_projectname;
EXCEPTION
WHEN NO_DATA_FOUND THEN
p_description:= NULL;
COMMIT;
END CMPPROJECTPROCSELECT;
execute CMPPROJECTPROCSELECT();
BEGIN CMPPROJECTPROCSELECT();
END;
EXECUTE is SQL*Plus command.
You are not passing the required parameters to the procedure. You have declared two parameters for your procedure:
p_projectname IN VARCHAR2,
p_description OUT VARCHAR2
So, you need to declare the required parameters and then pass it to the procedure:
DECLARE
proj_desc VARCHAR2(2000);
BEGIN
CMPPROJECTPROCSELECT('project_name', proj_desc);
-- use the OUT value of proj_desc later
END;
/
On a side note, you do not need COMMIT at all. It is required to permanently commit a DML and has nothing to do with a SELECT ..INTO clause.
SELECT DESCRIPTION INTO p_description FROM CMPPROJECT WHERE PROJECTNAME = p_projectname;
EXCEPTION
WHEN NO_DATA_FOUND THEN
p_description:= NULL;
COMMIT; -- You don't need COMMIT at all

I'm trying to run a concurrent request in APPS but i keep getting this error

When you define the Concurrent Program Executable in System Administration, make sure you the Execution File Name includes the schema.package.procedure, as in APPS.XXINV_ITEM_ORACLE_E5B0.inv_com_proc (no parenthesis).
It seems you're trying to execute the package itself - that won't work. You must execute a procedure/function within the package:

APPS.XXINV_ITEM_ORACLE_E5B0.inv_com_proc ( o_chr_errbuf, o_num_retcode);

I created a procedure in Oracle but am getting an error when I attempt to execute it. Below are listed the steps I am taking to create this procedure:
SQL> ed getuserinfo
create or replace procedure getUserInfo
( p_username out Users.username%TYPE,
p_password out Users.password%TYPE ) IS
BEGIN
select username,password into p_username,p_password from users where username='yogi';
END;

SQL> exec getuserinfo
BEGIN getuserinfo; END;

ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00201: identifier 'GETUSERINFO' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
What is the problem and how can I solve it? Olease can anyone help me?
You need to actually create the procedure, which you haven't done. You need a semi-colon after end and if you're creating it in SQL*Plus you need to add / to inform SQL*Plus that the block is finished:
create or replace procedure getUserInfo
( p_username out Users.username%TYPE,
p_password out Users.password%TYPE ) IS
BEGIN
select username,password into p_username,p_password from users;
END;
/
show error
It's always wise to add show error afterwards as well so that any errors are returned to the console in an understandable format.
Did you actually execute your create procedure statement? Did you get a "Procedure created." message? The fact that Oracle does not know of your getuserinfo procedure indicates to me that this statement was not performed.
I think it's procedure calling mistake!! Calling Should be like below:
SQL>var var1 varchar2(50);
SQL>var var2 varchar2(50);
SQL> exec getuserinfo(:var1, :var2);
SQL> print var1, var2;
Have Fun!!
You need to specify the out parameters when you call the procedure.
DECLARE
x Users.username%TYPE;
y Users.password%TYPE;
BEGIN
getuserinfo(x, y);
DBMS_OUTPUT.PUT_LINE('username: ' || x || ', password: ' || y);
END;
