Passing Queries to PL/SQL procedures

Hi,
Is there any way in PL/SQL procedure that i can pass two Queries Texts as parameters and return the result set by taking MINUS of the rwo Query results.
Thanx in Advace
Shafiq

Here is the principle...
SQL> conn scott/tiger
Connected.
SQL> CREATE OR REPLACE FUNCTION qry_minus
2     (p1 IN VARCHAR2, p2 IN VARCHAR2)
3     RETURN sys_refcursor
4 IS
5     return_value sys_refcursor;
6 BEGIN
7     OPEN return_value FOR p1||' MINUS '||p2;
8     RETURN return_value;
9 END;
10 /
Function created.
SQL> VAR q refcursor
SQL> exec :q := qry_minus('SELECT deptno FROM dept', 'SELECT deptno FROM emp')
PL/SQL procedure successfully completed.
SQL> print q
    DEPTNO
        40
SQL> Obviously because the query is text strings the calling program is responsible for ensuring the validity of the two queries (matching number and datatype of selected columns, etc).

Passing parameters to pl/sql procedure called in portal

Hi all,
I am trying to use a javascript window.open function to create a small popup window that is populated by a pl/sql procedure from inside portal.
I am trying to pass it a parameter to refine a SQL query running in that procedure, unfortunately I'm not sure of the syntax. The url that I'm trying to open in the new window looks like this:
http://my.server.com:7777/portal/pls/portal/myschema.mypackage.myprocedure
If I just run this, it works fine and the popup window opens correctly and displays all results. If I try to pass a parameter, it errors out with a 404 Page Not Found.
The parameter itself comes from a text field that the user can enter a value into. I am able to get the value of that text field and append it to the url I'm generating, but I can't find the proper syntax.
I've tried numerous syntax variants, but none of them seem to work. The procedure does have the parameter defined in both the spec and body and properly handles it. Can anyone point me in the right direction?
Thanks,
-Mike Markiw

You said you have a text field where a user enters a value, so I am assuming that you have form...
you can try following
<form action="/pls/portal/myschema.mypackage.myprocedure" method="post">
your text field "inVar"
your submit button
</form>
I am sure your myprocedure has inVar as an input...
If you just want to pass a value to a procedure you can always do following:
http://my.server.com:7777/portal/pls/portal/myschema.mypackage.myprocedure?inVar=the value

Passing array to pl/sql procedure - pls-00306 wrong number/types of args

its oracle 10.2 database;
I have a procedure with array parameters based on simple sql types.
eg
create or replace type vt_attrname is table of varchar2(50);
Now my call to the procedure works when the array is empty;
as soon as I bulk collect into my local array, I get a compilation error.
eg
declare
my_array vt_attrname;
begin
select label
bulk collect
into my_array
from table_name
where 1=1;
my_proc(p_array=>my_array); -- syntax error
end;if I pass null the call works but obviously array is empty.
I have read something about varray's being incompatible between sqltypes and pl/sql.
How do I get around this problem?
The bulk collect is working okay.
A small example would be appreciated.

Yep, I spotted the syntax error earlier.
However even though that seems to compile ok, I still get the problem with my package call.
heres the actual call from the code
vt_attrname and vt_attrvalues are types declared on another schema.
I have redeclared them on the current schema now.
create or replace type vt_attrname is table of varchar2(50);
create or replace type vt_attrvalue is table of varchar2(500);
create procedure <name>
as
v_cardapplattrtag   vt_attrname;
v_cardapplattrvalue vt_attrvalue;
for cardappl_cur in
    (select cardappl_id
       from ci_cardappl
      where custcard_id = cur.document_logical_number)
    loop
    select label
      bulk collect
      into v_cardapplattrtag
      from ci_applver_attribute
      where applver_id = v_applver_id;
      v_array_size := v_cardapplattrtag.count;
    -- populate this array
    -- ppt_cardapplattrtag comes from ci_pplver_attribute
    --ppt_cardapplattrvalue -- various
cci_setcardappl.SetCardApplAttrValue(
          pn_cardappl_id                 =>     cardappl_cur.cardappl_id,
          ppt_cardapplattrtag     =>      v_cardapplattrtag, -- works when null
          ppt_cardapplattrvalue   =>     NULL,

Passing ARRAYs to PL/SQL procedure

Hi,
How do i pass an array(from java program) to pl/sql stored procedure, and after doing some data manipulation in the database, i wanted to pass back the same array to the java program. Can anyone help me or post some sample code here?
Thanks in advance.

Are you hoping to use JDBC or ODBC to pass this array? If JDBC, I'd suggest asking this question on the JDBC forum.

Passing value from ADF to BPEL, and to PL/SQL procedure

1. I have created BPEL which take 2 inputs and concatenate them.
2. have created a PL/SQL procedure for invoking this BPEL( working fine).
Now i need to create a simple ADF page which contain 2 text box, 2 for input and 1 for result(concatenate), this will take 2 inputs and send them into BPEL, this will invoke the BPEL process and perform the necessary concatenate function...
in addition to this, i am passing code into PL/SQL procedure ...
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body xmlns:ns1="http://xmlns.oracle.com/OrderImportDemo">
<ns1:InputRequest>
<ns1:FirstName>abcdef</ns1:FirstName>
<ns1:LastName>aaaaaa</ns1:LastName>
</ns1:InputRequest>
</soap:Body>
</soap:Envelope>';
this code will take vaule from BPEL and run properly.
can you please help me,

thanks for help, but the problem is diff.
i don't have any schema, what i want i need to create a adf page that will contain 3 tent field, 2 for input and 1 for output. when i will enter 2 input field and click on ok button, this will invoke BPEL, BPEL will take these 2 inputs and do the concat on this and send back to adf with result.

Passing variable values to pl/sql procedures

Hi,
I wanted to log the step name and message into a table whenever a particular step/interface failed in the ODI package.
Ex:PKG1
A----OK--->B----OK-->C--OK-->LOG SUCCESS status into table. All steps are sequenced.
when not OK
A----KO--->B----KO-->C--KO-->LOG failed status into table with step and message.
I have created 4 variables in ODI and used these vairables in to pass values in pl/sql procedure scenario.
I have drag and drop procedure scenario and given values to every variable...thing is for i want to get the step name dynamically for the procedure scenario's variable i am directly passing
v_int_step=odiRef.getPrevStepLog("STEP_NAME").
I dont want drag and drop procedure for each KO and then pass values to v_int_step=A or B or C .
My scenario command look like this for KO
OdiStartScen "-SCEN_NAME=PROC_LOGEXE_STATUS" "-SCEN_VERSION=-1" "-LOG_LEVEL=3" "-SYNC_MODE=1" "-SESSION_NAME=PROC_CSA_LOGEXE_STATUS_CS_BRANCHES" "-FLEXCUBE_OFSAA.v_execution_status=E" "-project1.v_scen_int_name=A" "-project1.v_batch_id=PKG_GLOBAL_MNT_HANDOFF" "-project1.v_step_name=odiRef.getPrevStepLog("STEP_NAME")"

Hi,
Mistakes i found in the script,
1. You need to pass the variables with the "-<YOUR PROJECT CODE>.VARIABLE NAME" which i suppose would be in UPPER CASE.
2. You need to pass OdiPrevStepLog with <%=%> enclosed. So your script will looks like,
OdiStartScen "-SCEN_NAME=PROC_LOGEXE_STATUS" "-SCEN_VERSION=-1" "-LOG_LEVEL=3" "-SYNC_MODE=1" "-SESSION_NAME=PROC_CSA_LOGEXE_STATUS_CS_BRANCHES" "-FLEXCUBE_OFSAA.v_execution_status=E" "-PROJECT1.v_scen_int_name=A" "-PROJECT1.v_batch_id=PKG_GLOBAL_MNT_HANDOFF" "-PROJECT1.v_step_name=<%=odiRef.getPrevStepLog( "STEP_NAME" )%>"

block around every action in the finally, so if one fails, the others are still
done.
As long as you're writing good JDBC like that, there is no risk to telling the
pool to trust the code, by setting RemoveInfectedConnectionsEnabled to false.
That way you'll retain all the performance of the pools.

PL/SQL stored procedure and passing queries

Hi all.
This is a really "newbie"-type question....sorry !
I have written a PL/SQL procedure which takes a query (as varchar2) as an argument and returns the result in xml as a clob.
ie: SELECT returnXML('SELECT * FROM test_table') FROM DUAL;
This works fine, however how do I pass a query that also contains single quotes ?? I have tried escaping them in C-style with backslashes, but to no avail. As an example, I'd like to pass the following query to my procedure:
SELECT * FROM test_table WHERE name='TEST' AND id='200'
Any help would be greatly appreciated.
Regards,
Kristian.

Try doubling up the quotes, ie
SELECT returnXML('SELECT * FROM test_table WHERE name=''TEST'' AND id=''200''') FROM DUAL;

Passing variable of size greater than 32767 from Pro*C to PL/SQL procedure

Hi,
I am trying to pass a variable os size greater than 32767 from Pro*C to an SQL procedure.I tried assigning the host variable directly to a CLOB in the SQL section but nothing happens.In the below code the size of l_var1 is 33000.PROC_DATA is a procedure that takes CLOB as input and gives the other three(Data,Err_Code,Err_Msg) as output.These variables are declared globally.
Process_Data(char* l_var1)
EXEC SQL EXECUTE
DECLARE
l_clob clob;
BEGIN
l_clob := :l_var1
PROC_DATA(l_clob,:Data,:Err_Code,:Err_Msg) ;
COMMIT;
END;
END-EXEC;
I also tried using DBMS_LOB.This was the code that i used.
Process_Data(char* l_var1)
EXEC SQL EXECUTE
DECLARE
l_clob clob;
BEGIN
DBMS_LOB.CREATETEMPORARY(l_clob,TRUE);
DBMS_LOB.OPEN(l_clob,dbms_lob.lob_readwrite);
DBMS_LOB.WRITE (l_clob, LENGTH (:l_var1), 1,:l_var1);
PROC_DATA(l_clob,:Data,:Err_Code,:Err_Msg) ;
COMMIT;
END;
END-EXEC;
Here since DBMS_LOB packages allow a maximum of 32767,the value of l_var1 is not being assigned to l_clob.
I am able to do the above process provided i split l_var1 into two variables and then append to l_clob using WRITEAPPEND.i.e l_var1 is 32000 in length and l_var2 contains the rest.
Process_Data(char* l_var1,char* l_var2)
EXEC SQL EXECUTE
DECLARE
l_clob clob;
BEGIN
dbms_lob.createtemporary(l_clob,TRUE);
dbms_lob.OPEN(l_clob,dbms_lob.lob_readwrite);
DBMS_LOB.WRITE (l_clob, LENGTH (:l_var1), 1,:l_var1);
DBMS_LOB.WRITEAPPEND (l_clob, LENGTH(:l_var2), :l_var2);
PROC_DATA(l_clob,:Data,:Err_Code,:Err_Msg) ;
COMMIT;
END;
END-EXEC;
But the above code requires dynamic memory allocation in Pro*C which i would like to avoid.Could you let me know if there is any other way to perform the above?

Hi,
The Long Datatype has been deprecated use Clob or Blob. This will solve lot of problems inherent with the datatype.

Passing a structure from Java to PL/SQL Procedure

Environment: Oracle DB, Tomcat/Apache
How do we pass a structure (Table Record Type) from Java to a PL/SQL Stored Procedure?
We are doing JSP-->JavaClass/Bean to communicate to DB. We have an existing PL/SQL packages/Procedure to insert records into table (These procedures have record types as in/out parameters). So is there a way to call these from Java?

Oracle9 i JDBC Developers Guide and Reference(page 21-16):
It is not feasible for Oracle JDBC drivers to support calling arguments or return
values of the PL/SQL RECORD, BOOLEAN, or table with non-scalar element types.
However, Oracle JDBC drivers support PL/SQL index-by table of scalar element
types. For a complete description of this, see "Accessing PL/SQL Index-by Tables"
on page 16-21.
As a workaround to PL/SQL RECORD, BOOLEAN, or non-scalar table types, create
wrapper procedures that handle the data as types supported by JDBC. For example,
to wrap a stored procedure that uses PL/SQL booleans, create a stored procedure
that takes a character or number from JDBC and passes it to the original procedure
as BOOLEAN or, for an output parameter, accepts a BOOLEAN argument from the
original procedure and passes it as a CHAR or NUMBER to JDBC. Similarly, to wrap a
stored procedure that uses PL/SQL records, create a stored procedure that handles
a record in its individual components (such as CHAR and NUMBER) or in a structured
object type. To wrap a stored procedure that uses PL/SQL tables, break the data
into components or perhaps use Oracle collection types.

How to pass values to select clause in PL/SQL procedure

Am relatively new to PL/SQL programming and ran into the following issue...
Table
EMP_MASTER
ID VARCHAR2(10);
FIRSTNAME VARCHAR2(20);
DATA FOR EMP_MASTER
'1','SCOTT'
'2','TIGER'
I ran the following SQL Query
SELECT COUNT(*) FROM EMP_MASTER WHERE FIRSTNAME IN ('SCOTT','TIGER');
This select Query is working fine and we get the count = 2 as
expected. Now I want a procedure for the same fn()
CREATE OR REPLACE PROCEDURE TEST_EMP_MASTER(NAMELIST IN VARCHAR2)
IS
CNT NUMBER := 0;
BEGIN
SELECT COUNT(*) INTO CNT FROM EMP_MASTER WHERE FIRSTNAME IN (NAMELIST);
DBMS_OUTPUT.PUT_LINE('Output-->NAMELIST:'||NAMELIST||':cnt:'||cnt);
END;
Now when I test the procedure by passing just one value its working
fine. But when I want to pass multiple values, it doesnt work!
set serveroutput on;
i.e exec TEST_EMP_MASTER('SCOTT'); Works and the output is
Output--->NAMELIST:SCOTT:cnt:1
but don't get the expected output for exec TEST_EMP_MASTER('SCOTT,TIGER');
I understand that the IN modifier in the WHERE clause expects the
values as 'Value1','value2'....I tried different combination by the
passing the values with quotes '''value1'',''value2'''.....but no
success

Passing a list into a sql procedure via a unix shell.

9.2.0.6
for some dumb reason we cannot use java to do this task.
anyways
I need to build a list of all file in a particular directory. The list could be zero to very very long. I would like to be able to pass that list to a PL/SQL procedure.
this is in unix
I think I could do something like
var=f1,f2,f3,f4
sqlplus blah/blah $var
exec my_proc(&var);
I guess that would handle up to 32k in length. It would be up to me to parse the list.
I am really looking for an way to do this a bit slicker.. like with a ref cursor but I seem to be getting stuck.
Thanks

How to pass class object as in parameter in call to pl/sql procedure ?

hi,

I want to pass a cursor to a procedure as IN parameter.You can use the PL/SQL type called sys_refcursor - and open a ref cursor and pass that to the procedure as input parameter.
Note that the SQL projection of the cursor is unknown at compilation time - and thus cannot be checked. As this checking only happens at run-time, you may get errors attempting to fetch columns from the ref cursor that does not exist in its projection.
You also need to ask yourself whether this approach is a logical and robust one - it usually is not. The typical cursor processing template in PL/SQL looks as follows:
begin
open cursorVariable;
loop
    fetch cursorVariable bulk collect into bufferVariable limit MAX_ROWS_FETCH;
    for i in 1..bufferVariable.Count
    loop
      MyProcedure( buffer(i) );   --// <-- Pass a row structure to your procedure and not a cursor
    end loop;
