I am trying to call a stored procedure from BI Publisher, and need some help to achieve this.
Here is what I have:
In my Data Model I have the following code:
DECLARE
type refcursor is REF CURSOR;
xdo_cursor refcursor;
BEGIN
OPEN :xdo_cursor FOR
SELECT IPVOWN.F1(5) FROM DUAL;
COMMIT;
END;
Type of SQL = Non-standard SQL
Running this code works in SQL Developer when you remove the ":" from xdo_cursor, but in BI ":" is required. I get the following error in the log file:
<txt>java.sql.SQLException: ORA-06550: line 2, column 22:
PLS-00103: Encountered the symbol "." when expecting one of the following:
* & = - + ; < / > at in is mod remainder not rem
<an exponent (**)> <> or != or ~= >= <= <> and or like like2

thanks in advance.
Below are the steps/documentation on how to call a Function from BI Publisher:
1) Make sure you are using SYS_REFCURSOR.
2) Create your function like below in DB:
CREATE OR REPLACE FUNCTION FUNC1 (P1 VARCHAR2) RETURN SYS_REFCURSOR IS
XDO_CURSOR SYS_REFCURSOR;
BEGIN
IF P1 = 'USA' THEN
OPEN XDO_CURSOR FOR
'SELECT TO_CHAR(SYSDATE,''MM-DD-YYYY'') AS CURRENT_DATE, X.STATE FROM schemaName.XX1 X WHERE X.ID IN (100,200,400)';
RETURN XDO_CURSOR;
ELSE
OPEN XDO_CURSOR FOR
'SELECT TO_CHAR(SYSDATE,''MM-DD-YYYY'') AS CURRENT_DATE, X.STATE FROM schemaName.XX1 X WHERE X.ID IN (300,500,600)';
RETURN XDO_CURSOR;
END IF ;
END FUNC1;
3) Log in as System and grant execute to the BI User
GRANT EXECUTE ON schemaName.FUNC1 TO BI_User;
In your Data Set in BI Publisher - You can do the following to call the function: Make sure the type of SQL is "Procedure Call"
DECLARE
type refcursor is REF CURSOR;
xdo_cursor refcursor;
BEGIN
:xdo_cursor := SchemaName.func1(:P1);
END;

I get two errors, how can I fix it
LINE/COL ERROR
19/12 PLS-00103: Encountered the symbol "=" when expecting one of the
following:
. ( * # % & = - + < / > at in is mod remainder not rem then
<an exponent (**)> <> or != or ~= >= <= <> and or like like2
like4 likec between || multiset member submultiset
20/2 PLS-00103: Encountered the symbol "END" when expecting one of the
following:
begin function pragma procedure subtype type
current cursor delete
exists prior
You can save some coding and efficiency by replacing the cursor loop with the listagg function
select listagg(rtrim(nation.n_name),',')
from nation
inner join region
on region.r_regionkey = nation.n_nationkey
where region.r_regionname = listdisplay;
So that will collate all the matching rows, and use whatever delimiter is passed in. One thing to be aware of, you have listD varchar2(1000) so as long as the results from the query are less than 1000, you are OK. If you expect a larger result set, you may need to increase or use a clob.
If for some reason, you still want to use the loop method, then you need to fix your IF statement:
loop
fetch display_nation into nName;
exit when display_nation%notfound;
IF <condition> THEN
listD := listD || RTRIM(nName)||' , ';
END IF;
end loop;
This Code is:
CREATE OR REPLACE
PROCEDURE Actualiza_Saldo(fecha_ini IN DATE, fecha_fin IN DATE) RETURN NUMBER
AS
fechaTemp DATE;
diasTotales NUMBER := fecha_fin- fecha_ini;diasLaborables NUMBER;
sab VARCHAR2(10) := 'SÁBADO';dom VARCHAR2(10) := 'DOMINGO';diasTemp VARCHAR2(10);
BEGIN
diasLaborables:= diastotales;
FOR i IN 0..diasTotales LOOP
fechaTemp := fecha_ini + i;
DBMS_OUTPUT.PUT_LINE(to_char(fechaTemp));
diasTemp := TO_CHAR(fechaTemp, 'DAY', 'NLS_DATE_LANGUAGE=SPANISH');
IF (TRIM(diasTemp)=sab or TRIM(diasTemp)=dom) THEN
diaslaborables := diaslaborables-1;
END IF;
END LOOP;
dbms_output.put_line(diaslaborables);
RETURN diasLaborables;
END Actualiza_Saldo;
If I execute without returning it works, if I try to return a value it fails, I do not know what could be happening.
The error of oracle is:
Warning: la ejecución ha terminado con advertencias
PROCEDURE Actualiza_Saldo(fecha_ini Compilado.
Error que empieza en la línea 1 del comando:

*Cause: Usually a PL/SQL compilation error.

diaslaborables := diaslaborables-1;
END IF;
END LOOP;
dbms_output.put_line(diaslaborables);
END Actualiza_Saldo;
EXEC Actualiza_Saldo();
And the exit of the code without the returns and the test values is a route from the start date and the final date subtracting the days Saturday and Sunday.

But if I try to return the value the algorithm dies.
I have no idea what I am doing wrong or where is the fault, if you could help me I would greatly appreciate it.
Procedures cannot return a value, in Oracle, You can have out-parameters which would be visible after the procedure runs.
But here is another option you can try, instead of writing code to generate dates between two, try to do it using a single select query and open a out cursor to have the values populated after the proc completes
An example as follows
create or replace procedure generate_dates(start_date in date, end_date in date, result_set out sys_refcursor)
as
begin
open result_set for
select trunc(start_date)+level as output_dates
from dual
connect by level<=trunc(end_date)-trunc(start_date);
end;
if you are using sqlplus to connect to your database
you would call the proc as follows
var x refcursor
begin
generate_dates(date '2018-01-01',date '2018-12-31',:x);
end;
print x;
My mistake was that I was not doing a function but a procedure solved.
CREATE OR REPLACE
FUNCTION HR.Actualiza_Saldo(fecha_ini IN DATE/* DEFAULT '10/08/2018'*/, fecha_fin IN DATE/* DEFAULT '30/08/2018'*/) RETURN NUMBER

I'm trying to use the sum function with a package function but running into an "invalid identifier" bug. Here's some example code with the error causing function commented
create or replace type numType as object
(
myNum number
)
;
/
create or replace type numTypes is table of numType;
/
create or replace package testNumberPackage as
function ReturnNum(in_numType numType) return number;
end;
/
create or replace package body testNumberPackage as
function ReturnNum(in_numType numType) return number is
begin
return in_numType.myNum;
end;
end;
/
declare l_numTypes numTypes;
l_count number;
begin
l_numTypes := numTypes();
for i in 1 .. 100 loop
l_numTypes.extend(1);
l_numTypes(l_numTypes.last) := numType(i);
end loop;
select sum(n.myNum) into l_count from table(l_numTypes) n;
select sum(testNumberPackage.ReturnNum(n)) into l_count from table(l_numTypes) n; --causes the error
dbms_output.put_line(l_count);
end;
/
The exact error for this code is
ORA-06550: line 11, column 42
PL/SQL: ORA-00904: "N": invalid identifier
ORA-6550: line 11, column 3:
PL/SQL: SQL Statement ignored
Thanks for any help.
The first issue is that you can't pass a table into a parameter by using its alias. It doesn't even make sense to try doing that.
The next issue is how to get the column mynum that is returned from the table(l_numTypes) into the correct format to pass into testNumberPackage.ReturnNum, since it's of NUMBER datatype, and the function is expecting a numtype parameter.
To do that, you need to pass in an object with that column, like so: numtype(n.mynum).
The following works for me:
declare
l_numTypes numTypes;
l_count number;
begin
l_numTypes := numTypes();
for i in 1 .. 100 loop
l_numTypes.extend(1);
l_numTypes(l_numTypes.last) := numType(i);
end loop;
select sum(n.myNum) into l_count from table(l_numTypes) n;
select sum(testNumberPackage.ReturnNum(numtype(n.mynum))) into l_count from table(l_numTypes) n; --causes the error
dbms_output.put_line(l_count);
end;

Clear as mud?
I have SQL strings that my users write. They look like:
SELECT Name, Age from Users WHERE Name LIKE '%a%' AND {UsersWhere}
On the oracle server side when such an SQL is to be executed I want to replace the {tags} first. The replacements for the {tags} will be valid SQL sub strings I am holding in a table. Pre-manufactered sub sqls. So the treated string will be valid SQL.
Is there some fancy build-in Oracle function to make this happen?
Thanks for a hint!
I have written a small function for anyone interested:
CREATE OR REPLACE FUNCTION SA.REPLACE_VARIABLES (p_sql IN VARCHAR2)
RETURN VARCHAR2
IS
vs_return VARCHAR2 (4000);
-- Deklarationen
vs_sql VARCHAR2(4000);
vs_substring VARCHAR2(4000);
vs_variable VARCHAR2(200);
vs_variable_content VARCHAR2(4000);
BEGIN
vs_sql := p_sql;
IF INSTR(p_sql, '{') > 0 THEN
vs_substring := vs_sql;
WHILE LENGTH(vs_substring) > 0 LOOP
IF INSTR(vs_substring, '{') <> 0
THEN
vs_variable := SUBSTR(vs_substring, INSTR(vs_substring, '{'), INSTR(vs_substring, '}') - INSTR(vs_substring, '{') + 1);
-- Do whatever you want with the variable
--vs_sql := REPLACE(vs_sql, vs_variable, vs_variable_content);
-- Substring verkürzen
vs_substring := SUBSTR(vs_substring, INSTR(vs_substring, vs_variable) + LENGTH(vs_variable) + 1);
ELSE
vs_substring := '';
END IF;
END LOOP;
END IF;
RETURN vs_sql;
EXCEPTION
WHEN OTHERS
THEN
-- Err -handle
END REPLACE_VARIABLES;

I'd just keep it simple:
v_sql := REPLACE(v_sql, '{UsersWhere}', '...whatever you need...');
This is a followup to an older question about Oracle's row level security feature originally discussed here
I needed to modify the because the original code would return more than one results if the user was attached to multiple projects. So now I need to have multiple where conditions (ie where project = project_1 or project = project_2) passed to the security policy for this to work. To do this I tried modifying the code by using a for loop and it is not working...
--create function
create or replace function
table_access_policy
(obj_schema varchar2, obj_name varchar2) return varchar2
is
v_project_temp varchar2(9000);
begin
v_project_temp:= 'declare v_project varchar2(9000);
begin
v_project:= ''project = '';
for c in (select admin.access_list.project from admin.access_list where upper(admin.access_list.user_id) = SYS_CONTEXT (''USERENV'', ''SESSION_USER''))
loop
v_project := v_project || c.project_sn || '' or project = '' ;
end loop;
v_project := rtrim(v_project, '' or project = '');
end;';
return v_project_temp;
end;
The function saves/runs without any errors, but the policy itself throws an error when it's called. Is there a better way to do this?
Instead of putting the PL/SQL in a string you should run it and build up the v_project string to return. Such as:
--create function
create or replace function
table_access_policy
(obj_schema varchar2, obj_name varchar2) return varchar2
is
v_project varchar2(9000);
begin
v_project:= 'project = ';
for c in (select admin.access_list.project from admin.access_list where upper(admin.access_list.user_id) = SYS_CONTEXT ('USERENV', 'SESSION_USER'))
loop
v_project := v_project ||''''|| c.project_sn ||''''|||| ' or project = ' ;
end loop;
v_project := rtrim(v_project, ' or project = ');
return v_project;
end;
Ultimately the value that appears in v_project will go straight after a where in an SQL statement such as:
select * from data;
will become
select * from date where <v_project>;
So only something that follows a where should go in v_project.
