I'm trying to call an Oracle stored procedure within a package and I'm getting this error:
SQL Error: ORA-06576: not a valid function or procedure name
I'm using SQL Developer and this is the command I'm using
call WEATHERDATAUPDATES.GetLastRunDate("WeatherData")
Here is the package/procedure
PACKAGE BODY WEATHERDATAUPDATES AS
PROCEDURE GetLastRunDate(PROCESS IN VARCHAR2, RUNDATE OUT DATE) AS
BEGIN
SELECT rundate FROM Marcie.last_rundate
where process = PROCESS;
END GetLastRunDate;
END WEATHERDATAUPDATES;
I'm pretty new to Oracle Packages and not sure what I'm missing. I tried searching, but can't find an answer that works. Can someone tell me what I'm missing?
Thanks,
Marcie
In your procedure you are not putting the retrieved value anywhere, you should use INTO:
...
PROCEDURE GetLastRunDate(PROCESS IN VARCHAR2, RUNDATE OUT DATE) AS
BEGIN
SELECT rundate
INTO RUNDATE
FROM Marcie.last_rundate
where process = PROCESS;
END GetLastRunDate;
...
In the call pass the variable for the out parameter RUNDATE OUT DATE.
Put the call in a PL/SQL block:
DECLARE
lastRunDate DATE;
BEGIN
WEATHERDATAUPDATES.GetLastRunDate("WeatherData",lastRunDate);
-- do something with lastRunDate
END;
GetLastRunDate has 2 parameters, (process and rundate), but you're only passing 1 in your call.
Since you want to pass the second parameter out, one option would be to make it function and return the rundate.
PACKAGE BODY WEATHERDATAUPDATES AS
FUNCTION GetLastRunDate(PROCESS IN VARCHAR2)
RETURN DATE
AS
lDate DATE;
BEGIN
SELECT rundate
INTO lDate
FROM Marcie.last_rundate
where process = PROCESS;
RETURN lDate;
END GetLastRunDate;
END WEATHERDATAUPDATES;
You have shown the BODY of your package, but not the specification - check that GetLastRunDate is declared in the package spec.

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;
BEGIN
SELECT * INTO RESULT.EMP_ID,RESULT.NAME,RESULT.LOCATION,RESULT.CITY,RESULT.COUNTRY,RESULT.EMPLOYMENT_TYPE,RESULT.EMAIL_ID,RESULT.PHONE_NUMBER,RESULT.CREATED_BY,RESULT.CREATED_ON,RESULT.UPDATED_ON,
RESULT.UPDATED_BY,RESULT.DATE_OF_JOINING,RESULT.ROLE_ID,RESULT.SUPERVISOR_ID FROM TIMESHEET_EMPLOYEES
WHERE EMP_ID=EMP_ID1;
DBMS_OUTPUT.PUT_LINE('EMP_ID:'||RESULT.EMP_ID||' '||'NAME:'||RESULT.NAME||' '||'LOCATION:'||RESULT.LOCATION||' '||'CITY:'||RESULT.CITY ||' '||'COUNTRY:'||RESULT.COUNTRY||' '||'EMPLOYMENT_TYPE:'||

EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('SQLCODE'||' '||SQLCODE);
DBMS_OUTPUT.PUT_LINE('SQLERRM'||' '||SQLERRM);
END;
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'm working with a vendor's database, and I need to increment a value and return it. I have the right command, it updates the table, but the output in oracle developer just says "PL/SQL procedure successfully completed." How do I return NewReceiptNumber?
DECLARE
NewReceiptNumber int;
BEGIN
UPDATE SYSCODES
SET (VAR_VALUE) = VAR_VALUE+1
WHERE VAR_NAME='LAST_RCPT'
RETURNING VAR_VALUE INTO NewReceiptNumber;
END;
You are just depicting an anonymous block there, to VIEW the value of NewReceiptNumber in that code you'll have to use:
dbms_output.put_line(NewReceiptNumber).
as in:
DECLARE
NewReceiptNumber int;
BEGIN
UPDATE SYSCODES
SET (VAR_VALUE) = VAR_VALUE+1
WHERE VAR_NAME='LAST_RCPT'
RETURNING VAR_VALUE INTO NewReceiptNumber;
dbms_output.put_line(NewReceiptNumber);
END;
But if your intention is to actually return this value to another procedure or a call from your front-end, you'll have to declare a stored procedure and within that declaration indicate your output parameter, something like:
CREATE OR REPLACE PROCEDURE my_proc(newreceiptnumber out INT) AS
BEGIN
UPDATE syscodes
SET (var_value) = var_value+1
WHERE var_name='LAST_RCPT'
RETURNING var_value INTO newreceiptnumber;
END my_proc;
And of course it'll be a more robust solution if you send your updated values as parameters as well, this is just the minimal approach.
I have one requirement in which I have to design two procedure.First procedure will generate one output variable value and then second procedure will use to do its task. I am giving same kind of scenario in below code
create procedure existingProc(
begin
insert statementprogramming statement
);
create procedure MyProc(
begin
call existingProc();
-- Exsisting procedure return some value
-- and this value is used in MyProc
commit;
);
In the above code existingProc is already there in the system and I can not change it. IN the procedure transaction is begin but not committed. This procedure generate one value as Output param and MyProc will used this value.
I want that after executing the existingProc, MyProc procedure should get the value, but it is not happening and it is giving null.
what should i do here, Please help me. I can not share the code that why giving scenario.
Does this help clarify how to use the output parameters from one procedure in another procedure?
create procedure ExistingProc(output1 out number) is
begin
insert into someTable values ('some values')
RETURNING someCol INTO output1;
end;
create procedure MyProc(args ....) is
Result1 number; --output from existingProc
begin
ExistingProc(result1);
-- Use Result1 as needed
Update stuff ...
where id = Resutl1;
commit;
end;
I have a defined a new stored procedure but get a error while calling it,
CREATE OR REPLACE PROCEDURE SCOTT.getempsal(
p_emp_id IN NUMBER,
p_emp_month IN CHAR,
p_emp_sal OUT INTEGER)
AS
BEGIN
SELECT EMP_SAL
INTO p_emp_sal
FROM EMPLOYEE_SAL
WHERE EMP_ID = p_emp_id
AND EMP_MONTH = p_emp_month;
END getempsal;
And trying to call it:
getempsal(1,'JAN',OUT) --Invalid sql statement.
Your procedure contains an out parameter, so you need to call it in block like:
declare
a number;
begin
getempsal(1,'JAN',a);
dbms_output.put_line(a);
end;
A simple procedure (let's say with a number parameter) can be called with
exec proc(1);
or
begin
proc(1);
end;
Just write EXECUTE procedure_name('provide_the_valueof_IN parameter','value of in parameter', :k) ;
Run this statement a popup will come set the parameters as in out and the datatype too. U will see the output in another popup window.
I define a function outside a package, tried to call this function, failed.
how to fix it ? thanks
create or replace
package body test_erp AS
procedure init_data is
begin
logMessage('procedure init_data');
end init_data;
end test_erp;
/
show error
error is
PLS-00221: 'LOGMESSAGE' is not a procedure or is undefined
As the error suggests logmessage is not a procedure. It's a function. As functions return something you need to assign this to a variable. You know that logmessage returns a number so you need to declare a variable to put this return value into.
create or replace package body test_erp AS
procedure init_data is
l_success number;
begin
l_message := logMessage('procedure init_data');
dbms_output.put_line(to_char(l_success));
end init_data;
end test_erp;
/
However, it looks like logmessage should in fact be a procedure. I assume you're executing DML statements (update/insert) in this. A function call be used in a select statement unless this is the case, which means that there's always the possibility of an error occurring. If logmessage were a procedure you can declare an out parameter to tell the calling procedure whether everything worked or not; something like the following:
create or replace procedure logmessage( msg in varchar2, success out number) is
begin
insert into logs values(msg);
success := 1;
exception when others then
success := 0;
end logmessage;
You can then call it as follows:
create or replace package body test_erp AS
procedure init_data is
l_success number;
begin
logMessage('procedure init_data', l_success);
dbms_output.put_line(to_char(l_success));
end init_data;
end test_erp;
/
If logmessage isn't going to be used outside the package test_erp I would put it inside the package; it keeps the namespace cleaner and avoids it getting used mistakenly be another package / call etc.
Assuming that logMessage is the same function from this post:
Since logMessage is a function (and returns a number) you need to call it like this:
procedure init_data is
i number;
begin
i := logMessage('procedure init_data');
end init_data;
