I have a stored PL/SQL procedure (say X) that inserts records into a table. I am calling that procedure from another procedure (say Y). I have some parameters in procedure Y like para1,para2,para3 which can have two values either zero or one, for zero and one values I have one id stored in a TBL_SETUP, and when I call procedure X I want to check that if para1 is null then return null, if it is not null then check if it is one then return YES_ID and if it is no then return NO_ID.
I have tried something like this. I wrote a SELECT statement for getting YES_ID,NO_ID before calling the procedure and it is working fine, but when I write procedure call as below, it is giving me error "PLS-00204: Function or pseudo-column may be used inside a SQL statement only". How to use DECODE in a procedure call?
PROC_X(DECODE(para1,NULL,NULL,DECODE(para1,'1',YES_ID,NO_ID)),para2,NULL,NULL,DECODE(para2,'1',YES_ID,NO_ID)),para3,NULL,NULL,DECODE(para3,'1',YES_ID,NO_ID)),)
You could use SELECT INTO:
DECLARE
DECODE_RESULT VARCHAR2(100); -- or any suitable data type
BEGIN
SELECT DECODE(...) INTO DECODE_RESULT FROM dual;
PROC_X(DECODE_RESULT);
END;

I have a requirement where we have to call a oracle Stored Procedure which has collection type as input parameter.
So my stored procedure is like:
Create or replace package test
As
Type t is table of varchar(400) index by binary_integer.
Procedure testprc(p_client_id in number,t_no in number,t1 in t,t2 in t);
End;
Create or replace package body test
As
Procedure testprc(p_client_id in number,t_no in number,t1 in t, t2 in t)
is
Begin
for i in 1 ..tno loop
Insert into client
(Client_id,Client_phone,client_email) values (p_client_id,t1(i),t2(i));
End loop;
End;
End;
Now in the call to this stored procedure testprc.test I don't want to create a variable of type t and pass it to the stored procedure instead I want to directly pass the list of values to the SP.
Something like this
Exec testprc(13,1,{1=>'22737371'},{1=>'test#abc.com'}).
Is there any way I can achieve this.
If you are on 18c or higher, you can use a qualified expression to avoid having to create a temporary variable to hold associative arrays. For example:
SQL> exec test.testprc(13,1,test.t(1=>'22737371'),test.t(1=>'test#abc.com'))
PL/SQL procedure successfully completed.
I am trying to call procedure in oracle apex but I am facing problem in displaying the output of procedure while passing the parameter as emp_id to that procedure from oracle apex. Can anyone help me?
procedure that I have written in SQL developer tool.
create or replace PROCEDURE TEST_PROC(EMP_ID1 IN Number)
As
RESULT TIMESHEET_EMPLOYEES%ROWTYPE;

herein oracle apex in PLSQL code I am trying to call that procedure but I am not able to see any output.
BEGIN
TEST_PROC(:P1_EMPID);
END;
Can someone help me as I am new to APEX???
Apex can't display result of DBMS_OUTPUT.PUT_LINE.
Two simple options you might use:
add another, OUT parameter(s) to your current procedure, or
convert this procedure to a function which returns the result as a concatenated string
Both of them should return the result into an item on the page.
For example, if it were a procedure:
create or replace PROCEDURE TEST_PROC(EMP_ID1 IN Number,
par_result out varchar2
)
is
-- ... your current code goes here; I presume it does what you wanted
-- at the end, return the result as
par_result := 'EMP_ID:'||RESULT.EMP_ID||' '||'NAME:'||RESULT.NAME || ...
end;
Call it in a process as
TEST_PROC(:P1_EMPID, :P1_RESULT);
As of code you wrote: if you declared result as %rowtype, it is simpler to insert directly into it, not into every separate piece of it. For example:
select *
into result --> this
from timesheet_employees
where emp_id = emp_id1;
I created procedure under Program Units Oracle Forms
Code:
PROCEDURE VALIDATION_TEST
(p_mid we_group_hof_k.mstatusid%TYPE,
p_status we_group_hof_k.cardstatus%TYPE
) is
begin
insert into test
select mstatusid, cardstatus
from we_group_hof_k
where p_mid = 1
and p_status = 'A';
end;
This procedure complies successfully. I put this line on When-Button-Pressed Trigger "TEST" Button
VALIDATION_TEST;
When I try to compile "TEST" Button then I am getting following error:
wrong number or types of arguments in call to 'VALIDATION_TEST'
I am using oracle forms 11g.
How to solve this problem?
You have defined your procedure with two parameters. Your call of that procedure passes zero parameters. So you solve this by passing two parameters when you call the procedure.
Or maybe by removing the parameters from the procedure's signature. Because quite frankly your code doesn't make a lot of sense. The WHERE clause tests the parameters against hardcoded values. So either you select all the records in we_group_hof_k - if the passed arguments are 1 and 'A' - otherwise none.
Perhaps this is what you need?
PROCEDURE VALIDATION_TEST
(p_mid we_group_hof_k.mstatusid%TYPE,
p_status we_group_hof_k.cardstatus%TYPE
) is
begin
insert into test
select mstatusid, cardstatus
from we_group_hof_k
where mstatusid = p_mid
and cardstatus = p_status;
end;
Then you would call your procedure like this:
VALIDATION_TEST(1, 'A');
Although, as this procedure is called from Oracle Forms probably you need to pass in items from a Forms block. But only you know that for sure.
Is it possible to select the parameters for calling a procedure from the select statement?
EXECUTE PROCEDURE_NAME(para1,para2,para3,para4);
commit;
Is it possible to select para1,para2,para3,para4 from a select query?
EXECUTE PROCEDURE_NAME((SELECT PARA1,PARA2,PARA3,PARA4 FROM TABLEA))
COMMIT;
I do not have access to modify the procedure.
As a slight variation on what #vc74 suggested, you could just replace your EXECUTE command (which, assuming this is SQL*Plus or SQL Developer anyway, is just a wrapper for an anonymous block anyway) with an explicit anonymous block:
begin
for r in (SELECT PARA1,PARA2,PARA3,PARA4 FROM TABLEA) loop
PROCEDURE_NAME(r.PARA1,r.PARA2,r.PARA3,r.PARA4);
end loop;
end;
/
(I've left the bits from your original call uppercase and the new bits lower case mostly to distinguish them.)
Using a loop just means you don't need to declare local variables and select into those. It would also allow you to process multiple rows from the table, though I see form a comment you only expect one row. However, the flip side of that is it won't complain if there are no rows, or if there is more than one row, as the variable approach would do.
You could also use a record type to avoid declaring all the parameters separately:
declare
l_row tablea%rowtype;
begin
SELECT * into l_row FROM TABLEA;
PROCEDURE_NAME(l_row.PARA1,l_row.PARA2,l_row.PARA3,l_row.PARA4);
end;
/
This now does expect exactly one row to be found in the table.
You can call the functions in sql. So if you are able to create a function in your schema then you can do the following:
create a function function_name in your schema that calls the procedure procedure_name and returns some dummy result
use this function in sql query: select function_name(para1,para2,para3,para4) from tablea
example of function:
create or replace function function_name(
p1 varchar2,
p2 varchra2,
p3 varchar2,
p4 varchar2
) return number
is
begin
procedure_name(p1,p2,p3,p4); -- here you execute the procedure
return null;
end;
I have a package consists of function and procedures
CREATE OR REPLACE PACKAGE BODY schema.pkg_product as
function xxxxx()
procedure product_get(p_product_id IN Number,
P_direct_balance Out Number,
P_indirect_balance Out Number) IS
v_request CLOB :=<soapenv:Envelope xmnlns:----->
v request_end varchar(100) := <can:----->
BEGIN
Selct statement
END
My question is can we can Call the procedure in the select statement and how can I get the P_direct_balance , P_indirect_balance. if so in the select query coz I want to retrieve that data from the procedure.
It's not possible. You could write a function but you cannot use functions with out parameters in SQL. So you'll have to rewrite your code. For instance create two functions that return p_direct_balance and p_indirect_balance.
If rewriting the procedure to be a function with an out parameter is not possible, I would suggest altering the procedure to write the relevant values to a temporary table and commit. Then use your select statement to retrieve the values from the temp table.
