I've create a stored procedure (SP) within Oracle that has an OUT parameter of type SYS_REFCURSOR, this SP executes as expected within Oracle.
CREATE OR REPLACE PROCEDURE SCHEMA.MyProc
(
p_Code IN varchar2,
p_FromDate IN Timestamp,
p_ToDate IN timestamp,
p_ResultSet OUT SYS_REFCURSOR
)
AS
BEGIN
OPEN p_ResultSet FOR
-- Obtain required data
END SF_EquipmentStatusHistory;
/
However when the Spotfire guy in the organisation tries to create new Procedure in Spotfire and reference my SP, Spotfire complains that it can't have an OUT parameter.
Reading this link Spotfire Procedure Overview, seems to suggest that Spotfire "Information Designer only support procedures that return data of the type REF CURSOR"
Can somebody please help as to how I resolve this issue?
Thanks
Resolved:
As suggested changing the Stored Procedure to a Function within Oracle did resolve the problem of Spotfire complaining about OUT parameter:
CREATE OR REPLACE FUNCTION SCHEMA.MyFunc
(
p_Equipment_code IN varchar2,
p_FromDate IN Timestamp,
p_ToDate in timestamp
)
return SYS_REFCURSOR
AS p_ResultSet sys_refcursor;
BEGIN
OPEN p_ResultSet FOR
-- Obtain required data
return p_ResultSet;
END MyFunc
/
you might try something like this
CREATE OR REPLACE FUNCTION SCHEMA.MyFuctRC
(
p_Code IN varchar2,
p_FromDate IN Timestamp,
p_ToDate IN timestamp
)
Return sys_refcursor
AS
my_rc sys_refcursor ;
BEGIN
OPEN my_rc FOR
-- your select statement
return my_rc;
END MyFuctRC;

I want to use 1st parameter of my procedure EMP_ID as IN OUT parameter. Originally it's IN parameter and this procedure is working fine, but as the last line concern
htp.p('Inserted for Employee-id '||EMP_ID);
I want to use this line in anonymous block and most importantly it should be a bind variable because I am creating the REST API in which user will only enter values and it will be taken as bind variable in oracle Apex and the below procedure is working fine with respect of IN parameter.
create or replace procedure att_time_ins (EMP_ID in varchar2, ORG_ID in number,V_TIME_STATUS in number) is
BEGIN
INSERT INTO TIME_ATTENDANCE_POOL
(EMPLOYEE_ID, ATTENDANCE_DATE,TIME_HOURS,TIME_MINUTES,TIME_STATUS,LOCATION_ID,ORG_ID,PREPARED_ON )
VALUES
(EMP_ID, to_date(sysdate,'DD/MM/YYYY'),to_char(sysdate,'HH24') ,to_char(sysdate,'MI'),V_TIME_STATUS,null,ORG_ID,
to_date(sysdate,'DD/MM/YYYY') );
COMMIT;
time_management.create_attendance_sheet(v_org_id => ORG_ID,
v_employee_id => EMP_ID,
target_date => to_date(sysdate,'DD/MM/YYYY'));
htp.p('Inserted for Employee-id '||EMP_ID);
end att_time_ins;
I am calling my procedure in this way
begin
att_time_ins(:employee_id,:org_id,:time_status);
end;
Please help me to modify this stuff according to IN OUT Parameter i.e Employee_id should be IN OUT parameter. There is no proper documentation regarding passing bind variables as in out prameter in PLSQL Block.
Let us say you have a procedure named PR_PROC, you can use VARIABLE statement for passing IN OUT or OUT kind of variables.
CREATE OR REPLACE PROCEDURE PR_PROC (EMP_NAME IN VARCHAR2,
EMP_ID IN OUT VARCHAR2)
IS
BEGIN
DBMS_OUTPUT.PUT_LINE (EMP_NAME||EMP_ID);
END;
VARIABLE KURSOR VARCHAR2
BEGIN
:KURSOR:='4';
PR_PROC('SENIOR',:KURSOR);
END;
Note: If you are using TOAD Editor you can press F5 to make it work.
Oracle VARIABLE
I am trying to Insert a line into a table using PLSQL. The table name is DOCUMENT_ISSUE_HISTORY. I am using an API Procedure name PROCEDURE
Insert_New_Line_ (
doc_class_ IN VARCHAR2,
doc_no_ IN VARCHAR2,
doc_sheet_ IN VARCHAR2,
doc_rev_ IN VARCHAR2,
info_category_db_ IN VARCHAR2,
note_ IN VARCHAR2 );
I am confused if PRECEDURE can return value like function does.
I am doing this:
DECLARE
doc_class_ varchar2(4000) := 'CVS FILE';
doc_no_ varchar2(4000) := '01004901.DWG-DWF';
doc_sheet_ varchar2(20) := 1;
doc_rev_ varchar2(20) := -1;
info_category_db_ VARCHAR2(20) := NULL;
note_ VARCHAR2(4000) := 'TEXTING TO UPDATE or FIeld to update';
BEGIN
Document_Issue_History_API.Insert_New_Line__ (doc_class_ ,doc_no_,doc_sheet_,doc_rev_ ,info_category_db_,note_);
end;
How can I can insert the line in the table?
Functions have return values and hence may appear anywhere an expression may be used (such as to the right of the assignment operator, or as a column expression in a SQL statement) while Procedures do not have return values and may not be used as expressions.
This is not to say that procedures can't return values, because they can as long as they are OUT or IN/OUT parameters. You just can't use the procedure directly in an expression.
Similarly since Functions do have a return value (other than those parameters specified as OUT or IN/OUT parameters) they must be used in an expression and can't be called directly.
I am recently implementing the dynamic sql in my cide and quite new to the concept. I was trying with the following function that will take the column name and update the value via dynamic function call.However the function gives out an error while compiling.Please find the code as below:
function upd_tab(col_name in varchar2,val in number)
return pls_integer
is
BEGIN
EXECUTE IMMEDIATE 'UPDATE EMPLOYEE1 SET '||col_name||'= :THE_VALUE WHERE EMP_NAME IN(:NAME1,:Nme2)'
using val,john,aaron;
RETURN SQL%ROWCOUNT;
END;
Thank you in advance for your help.
Here you have to declare variables in the using clause. Hope below snippet helps.
FUNCTION upd_tab(
col_name IN VARCHAR2,
val IN NUMBER)
RETURN pls_integer
IS
BEGIN
EXECUTE IMMEDIATE 'UPDATE EMPLOYEE1 SET '||col_name||'= :THE_VALUE WHERE EMP_NAME IN(:NAME1,:Nme2)' USING val,'john','aaron';
RETURN SQL%ROWCOUNT;
END;
I get the below error while executing code
create or replace
function contact_restriction_function(obj_schema varchar2, obj_name varchar2)
return varchar2 is
v_contact_info_visible hr_user_access.contact_info_visible%type;
begin
-- Here you can put any business logic for filtering
select nvl(max(contact_info_visible),'N')
into v_contact_info_visible
from hr_user_access
where user_name = user;
-- SQL filter / policy predicate
return ''''||v_contact_info_visible||''' = ''Y'' ';
end;
/
after show erros command i got this
show errors
Errors for FUNCTION CONTACT_RESTRICTION:
LINE/COL ERROR
-------- -----------------------------------------------------------------
3/1 PLS-00103: Encountered the symbol "?" when expecting one of the
following:
begin function pragma procedure subtype type
current cursor delete
exists prior external language
This is the remaining code:
begin
dbms_rls.add_policy(object_schema => 'HR' ,
object_name => 'EMPLOYEES' ,
policy_name => 'Contact_Restriction_Policy' ,
policy_function => 'contact_restriction_function' ,
sec_relevant_cols=>'EMAIL,PHONE_NUMBER'Contact Info ,
sec_relevant_cols_opt=>dbms_rls.all_rows);
end;
below is the actual code which i am executing before show errors:
create or replace function contact_restriction(obj_schema varchar2, obj_name varchar2)
return varchar2
is
v_contact_info_visible IN user_access.contact_info_visible%type;
begin
select nvl(max(contact_info_visible),'N')
into v_contact_info_visible
from user_access where username = user;
return 'v_contact-info_visible ='|| 'Y';
end;
Your original question shows an error message referring to "?", but the code yout posted a as comment would raise a similar error for `"IN"' instead:
2/24 PLS-00103: Encountered the symbol "IN" when expecting one of the following:
That is because you've used IN for a local variable; but IN, OUT and IN OUT are only applicable to stored procedure parameters. You could have declared the function with an explicit IN for example, though it is the default anyway:
create or replace function contact_restriction(obj_schema IN varchar2, ...
So that needs to be removed from the v_contact_info_visible declaration. You've linked to an example you're working from, but you've removed a lot of important quotes from that, which will still cause it to fail when executed as a part of a VPD; because v_contact_info_visible will be out of scope to the caller. And you have a typo, with a hyphen instead of an underscore.
You need something like:
create or replace function contact_restriction(obj_schema varchar2,
obj_name varchar2)
return varchar2 is
v_contact_info_visible user_access.contact_info_visible%type;
begin
select nvl(max(contact_info_visible),'N')
into v_contact_info_visible
from user_access
where username = user;
return ''''||v_contact_info_visible ||''' =''Y''';
end;
/
When called, that will return a string which is either 'N'='Y' or 'Y'='Y'. VPD will include that as a filter in the original query, which will either prevent any rows being returned (in the first case) or have no effect and allow all rows that match any other existing conditions to be returned (in the second case).
The syntax of the function header is incorrect. It should be:
create or replace function contact_restriction(obj_schema IN varchar2, obj_name IN varchar2)
return varchar2

am creating a package in pl/sql . with in this i declared the ref cursor . With in procedure am using select statement with multiple column name . but am not able to get the result.
here i attached my code. Help me to correct the error. Am new to pl/sql
code
CREATE OR REPLACE PACKAGE types AS
TYPE cursor_type IS REF CURSOR;
END Types;
/
CREATE OR REPLACE
PROCEDURE get_CDR_rs (p_no IN zkv.FLD_callingPartyNumber%TYPE,
CDR_recordset OUT SYS_REFCURSOR) AS

FROM CISCOCUIC_TBL
WHERE FLD_callingPartyNumber= p_no

END LOOP;
CLOSE l_cursor;
END;
/
Error
9/41 PL/SQL: ORA-00936: missing expression
5/5 PL/SQL: SQL Statement ignored
First thing is there is a syntax error in the procedure. It should be
CREATE OR REPLACE
PROCEDURE get_CDR_rs (p_no IN zkv.FLD_callingPartyNumber%TYPE,
CDR_recordset OUT SYS_REFCURSOR) AS
BEGIN
OPEN CDR_recordset FOR
SELECT FLD_callingPartyNumber,
FLD_dateTimeConnect
FROM CISCOCUIC_TBL
WHERE FLD_callingPartyNumber= p_no
ORDER BY FLD_callingPartyNumber; -- there was a comma which is not required or you
-- missed a column
END get_CDR_rs;
/
Secondly where is get_CDR_rs being called to retrieve the results?
Thirdly why do you need the following? because you are using sys_refcursor
CREATE OR REPLACE PACKAGE types AS
TYPE cursor_type IS REF CURSOR;
END Types;
/
If you would like to see the results of your procedure which returns sys_refcursor, do as follows
variable rset refcursor;
DECLARE
p_no zkv.FLD_callingPartyNumber%TYPE;
BEGIN
p_no := '123';
get_CDR_rs (p_no, :rset);
END;
/
print rset
