I am passing String array(plcListchar) to Stored Procedure, i would like to use this String array in IN() clause.
i can not use plcListchar directly in IN() clause.
Let me show how i am crating plcListchar string array in JAVA.
String array[] = {"o", "l"};
ArrayDescriptor des = ArrayDescriptor.createDescriptor("CHAR_ARRAY", con);
ARRAY array_to_pass = new ARRAY(des,con,array);
callStmtProductSearch.setArray(4, array_to_pass);
for crating CHAR_ARRAY,
create or replace type CHAR_ARRAY as table of varchar2;
i want use plcListchar in IN clause. the following is my Stored Procedure.
CREATE OR REPLACE PROCEDURE product_search(
status IN varchar2,
plcList IN varchar2,
i_culture_id IN number,
plcListchar IN CHAR_ARRAY,
status_name OUT varchar2,
culture_code OUT varchar2)
AS
CURSOR search_cursor IS
SELECT p.status_name, p.culture_code
FROM PRISM_ITEM_cultures#prism p
WHERE p.publishable_flag=1
AND p.isroll =0
AND status = '-1'
AND p.plc_status IN ( );
BEGIN
OPEN search_cursor;
FETCH search_cursor INTO status_name, culture_code ;
CLOSE search_cursor;
END;
Could you please suggest me how to use, if you like to suggest any other logic, it is great.
Assuming that your collection is defined in SQL, not just in PL/SQL, you can use the TABLE operator (the definition you posted isn't syntactically valid-- you'd need to specify a length for the VARCHAR2)
AND p.plc_status IN (SELECT column_value
FROM TABLE( plcListchar ))
Since I don't have your tables, an example using the SCOTT schema

I have certain numbers eg., (1,2,3,7,8) which need to be stored in an object (let's say, l_list) and this l_list will used as the value of the parameter in a function while calling a select query.
Storing data globally:
l_list := (1,2,3,7,8);
Creating a function:
create or replace function f_get_result (p_list number)
return varchar2
as
l_result varchar2(100);
Begin
select l_code
into l_result
from table_1;
return l_result;
end f_get_result;
Calling the function in select query:
select f_get_result(l_list) from dual;
Till now I have tried to define the datatype of the parameter as type table and varray. But, it didn't work.
Here is the code which I used:
-- creating a type ---
CREATE OR REPLACE TYPE num_array AS TABLE OF varchar2(100);
-- the function ---
create or replace function fn_id_exp(p_branch in num_array)
return varchar2
is
txt varchar2(1000);
txt_1 varchar2(1000);
begin
for i in 1..p_branch.count loop
select branch_name into txt_1 from tbl_branch
where branch_code = p_branch(i);
txt := txt ||txt_1||chr(10);
end loop;
return txt;
end;
-- the select query ---
select fn_id_exp(num_array('100','200')) from dual;
expectation: select fn_id_exp(l_list) from dual; , need to use this much, num_array should not be there,
where l_list is an object which is storing certain numbers like (100,200,300).
Please, help me in this, I am bit new in this. Can somebody, give me an an appropriate example regards this?
Note: It doesn't matter where and what datatype these number are getting stored. Requirement is just to call all the numbers(1,2,3,7,8) in this:
select fn_id_exp(l_list) from dual;
Another option, which doesn't require you to use your own type, is to use Oracle's built-in types.
Here's an example; function returns employees that work in departments passed as a collection.
SQL> create or replace function f_test (par_deptno in sys.odcinumberlist)

Note that such a result might be more convenient than returning a string which "mimics" rows in a table (whose values are separated by line feed character), as you'd still might need to split them into rows if you wanted to further process the result.
You said:
expectation: select fn_id_exp(l_list) from dual; , need to use this much, num_array should not be there
But - why not? What's wrong with num_array (or whichever type name you'd use)? That's the syntax, you should follow it if you want to get the result. Silly requirements, in my opinion.
Anyway: you could pass a string of e.g. comma-separated numeric values such as in this example; you'll have to split them to rows. See if it helps.

Use a collection:
CREATE TYPE number_array AS TABLE OF NUMBER;
Then:
CREATE FUNCTION fn_id_exp(
p_branch in number_array
) return varchar2
IS
txt varchar2(1000);
BEGIN
SELECT LISTAGG(branch_name, CHR(10)) WITHIN GROUP (ORDER BY rn)
INTO txt
FROM (SELECT ROWNUM AS rn,
COLUMN_VALUE AS id
FROM TABLE(p_branch)) i
INNER JOIN tbl_branch b
ON (i.id = b.branch_code);
RETURN txt;
END;
/
Then:
select fn_id_exp(number_array(100,200)) from dual;
Given the sample data:
CREATE TABLE tbl_branch (branch_code, branch_name) AS
SELECT 100, 'Leafy Stem' FROM DUAL UNION ALL
SELECT 200, 'Big Twig' FROM DUAL;
Outputs:
FN_ID_EXP(NUMBER_ARRAY(100,200))
Leafy StemBig Twig
However
It may be simpler to not use a function and just use a query:
SELECT branch_name
FROM tbl_branch
WHERE branch_code IN (100, 200)
ORDER BY branch_code;
or, if you want to use the array::
SELECT branch_name
FROM tbl_branch
WHERE branch_code MEMBER OF number_array(100, 200)
ORDER BY branch_code;
or, pass in an array as a bind parameter (via JDBC, etc.) then:
SELECT branch_name
FROM tbl_branch
WHERE branch_code MEMBER OF :your_array
ORDER BY branch_code;
Which output:
BRANCH_NAME
Leafy Stem
Big Twig

Update
If you want a static array then you can create a package:
CREATE PACKAGE static_data IS
FUNCTION getList RETURN NUMBER_ARRAY;
END;
/
With the body:
CREATE PACKAGE BODY static_data IS
list NUMBER_ARRAY;
FUNCTION getList RETURN NUMBER_ARRAY
IS
BEGIN
RETURN list;
END;
BEGIN
list := NUMBER_ARRAY(100, 200);
END;
/
then you can use it in your query:
select fn_id_exp(static_data.getlist()) from dual;
or
SELECT branch_name
FROM tbl_branch
WHERE branch_code MEMBER OF static_data.getlist()
ORDER BY branch_code;

I group a series of IDs using LISTAGG.
Here is an example of a returned value-
A 1,2,3,4,5 PROC.ABC
B 6,7,8 PROC.ABC
C 2,3,4 PROC.DEF
I then try to use a cursor and pass each value into the following procedure:
PROCEDURE abc(id_list IN VARCHAR2) IS
BEGIN
UPDATE table_a SET flag = 1 WHERE id IN (id_list);
END;
This errors out ("Invalid Number" error) because id_list is being inserted as
'1,2,3,4,5'
, not
1,2,3,4,5
. How can I get this to work? I would prefer not to use dynamic SQL if possible.
If you have APEX installed in your database, you can use the APEX_STRING.SPLIT function to split your string by commas. If you know id_list is always going to be numbers, you can use APEX_STRING.SPLIT_NUMBERS as well.
PROCEDURE abc (id_list IN VARCHAR2)
IS
BEGIN
UPDATE table_a
SET flag = 1
WHERE id IN (SELECT * FROM TABLE (apex_string.split (id_list, ',')));
END;
Firstly you need to create a function that returns a list of values.
FUNCTION TVF_SPLIT (expression CLOB, delimiter CHAR) RETURN sys.ODCIVARCHAR2LIST
AS
v_TYPE_TABLE_SEPRATOR sys.ODCIVARCHAR2LIST :=sys.ODCIVARCHAR2LIST();
v_xml_data CLOB;
BEGIN
v_xml_data := '<r><n>' || replace(expression,delimiter,'</n><n>') || '</n></r>';
SELECT * BULK COLLECT INTO v_TYPE_TABLE_SEPRATOR FROM
(
SELECT * FROM
XMLTABLE ( '/r/*'
PASSING xmltype(v_xml_data)
COLUMNS
r VARCHAR2(4000) PATH '/n'
) xmlt
);
RETURN v_TYPE_TABLE_SEPRATOR;
END;
Select * from table(TVF_SPLIT('1,2,3,4,5',','));
Don't use listagg; create a collection type.
create or replace type t_vchar_tab as table of integer
Then replace listagg in the query-
CAST(COLLECT(id) AS t_vchar_tab) as id_list
Then the procedure should reference the collection w/use of MEMBER
PROCEDURE abc(id_list t_vchar_tab) IS
BEGIN
UPDATE table_a SET flag = 1 WHERE id MEMBER OF id_list;
END;
I have an Oracle package which contains a function. This function has 3 inputs. I need to pass multiple values to each input. I could automate a process which runs it multiple times with each combination of variables but I would like to only make one call to the database.
Simplified Code
declare
ln_ret number;
begin
ln_ret := dbo.pkg_rpa.mis_run_script (
'%2020%',
'111','222','333','444',
'1234','2345','6192','1204'
);
dbms_output.put_line('ln_ret=' || t.t (ln_ret));
end;
CREATE OR REPLACE
package dbo.pkg_rpa IS
function mis_run_script (
p_input_dt in varchar2,
p_hospital_id in varchar2,
p_procedure_code in varchar2) RETURN number;
end PKG_RPA;
/
CREATE OR REPLACE
PACKAGE BODY dbo.pkg_rpa IS
function mis_run_claim_assessment_script (
p_input_dt in varchar2,
p_hospital_id in varchar2,
p_procedure_code in varchar2
)
Begin
for i in (select table_name from user_tables where lower(table_name) = 'temp_rpa') loop
execute immediate 'drop table temp_rpa';
end loop;
execute immediate ' create table temp_rpa as select distinct ci.claim_id, count(ci.receipt_id) as count_receipts,
sum(ci.billed_amount) as total_billed_amount, count(*) as claim_items
from claim_item ci left join claim_header ch on ch.claim_id = ci.claim_id
left join cd_hos ho on ho.hospital_id = ci.hospital_id
left join claim_type_header cl on cl.claim_id = ci.claim_id
where cl.claim_status is null and ch.deleted_flag is null
and ch.input_dt like p_input_dt
and ci.hospital_id in (p_hospital_id)
and (ci.claim_id, NVL(ci.claim_item_id,0)) in (select claim_id, NVL(claim_item_id,0) from cd_roc_claim_item
where procedure_code in (p_procedure_code))
and (ci.claim_id, NVL(ci.claim_item_id,0)) not in (select claim_id, NVL(claim_item_id,0) from cd_roc_claim_item
where procedure_code not in (p_procedure_code))
group by ci.claim_id
having sum(case when ci.service_type_id is null then 1 end) = 1)';
End;
end mis_run_script;
end PKG_RPA;
/
Pass it with quoted string (Q'<delimeter><your_actual_string><delimeter>') as follows:
begin
ln_ret := dbo.pkg_rpa.mis_run_script (
'%2020%',
Q'#'111','222','333','444'#',
Q'#'1234','2345','6192','1204'#'
);
dbms_output.put_line('ln_ret=' || t.t (ln_ret));
end;
What you could do is using an associative array as input type. Instead of varchar2, use dbms_sql.varchar2a as date type for the 2nd and 3rd arguments.
But if the arguments are related to each other, let's say
p_hospital_id '111' belongs to procedure code '1234'
p_hospital_id '222' belongs to procedure code '2345'
etc.
I think you would want to create a custom record type, create a table type of the record type and use that as an parameter.
Your arguments become p_hospital_ids in dbms_sql.varchar2a in both the package specification and the package body.
In you code, you would have to loop over it and instead of dropping the table and recreate it each time, you drop it once at the start and add data within the loop;
truncate table; --alternative drop and create
for i in 1 .. p_hospital_ids.count loop
insert into temp_rpa
select <columns>
from claim_item ci
......
and ci.hospital_id = p_hospital_ids[i]
end loop
You may want to refer to the below example which is taken from Oracle Website. Hope it helps.
CREATE OR REPLACE TYPE nt_type IS TABLE OF NUMBER;

You don't need dynamic SQL at all.

I have plsql function. And this function has query like as below:
select colum_name
from table_name
where filter_coloumn_name in ( select filter_coloumn_name from table_name_2);
My function is used by other query to return value from query. This query which use this function take more time. Even the site (front screen) down. Because table_name_2 has three million record. So that i must use some performance tuning method in my function. I change my function query like as below:
cursor my_cursor IS
select filter_coloumn_name from table_name_2;
TYPE cursor_array_type IS TABLE OF my_cursor%ROWTYPE INDEX BY BINARY_INTEGER;
m cursor_array_type;
TYPE cursor_table_type IS TABLE OF VARCHAR2(20) INDEX BY BINARY_INTEGER;
cursor_table_object cursor_table_type;
fetch_size NUMBER := 5000;
index_var number;
begin
index_var := 1;
open my_cursor;
loop
FETCH my_cursor BULK COLLECT
into m LIMIT fetch_size;
exit when my_cursor %notfound;
for i in 1 .. m.count loop
cursor_table_object (index_var) := m(i).filter_coloumn_name;
index_var := index_var + 1;
end loop;
end loop;
Close my_cursor;
select colum_name
from table_name
where filter_coloumn_name in (cursor_table_object);
select colum_name
from table_name
where filter_coloumn_name in (cursor_table_object);
Namely, i want fetch all values at one time, and then i want use this table object like as above. But i can't use table object with in condition expression in sql query.
I take PLS-00382: expression is of wrong type error.
I want to use this table object like as below:
select colum_name
from table_name
where filter_coloumn_name in ('bla', 'bla bla', 'bla bla bla');
Should i convert table object to the array ?
A suggestion, based on what you've said so far: how about using a table function? It makes it possible to use something like statement you wanted to use, i.e.
select colum_name from table_name where filter_coloumn_name in (cursor_table_object);
but which returns
PLS-00382: expression is of wrong type
Here's an example based on Scott's schema. Have a look:
SQL> create or replace function f_test

You must use exists instead of in, also table_name_2 must have index over filter_coloumn_name field.
Using cursor only what you get is full access to a big table.
I have this PL / SQL function that accepts the name of a student (f_name). The function then displays all of the information for the given student from a premade table called students. The table contains 5 columns, 2 number type, and 3 varchar2 type. If the name isn't found in the table an error message is returned. My code so far is
CREATE OR REPLACE FUNCTION studentName(
f_name IN VARCHAR2)
RETURN
IS
v_test students%rowtype;
CURSOR c1
IS
SELECT * FROM students WHERE first_name = f_name;
BEGIN
OPEN c1;
FETCH c1 INTO v_test;
IF c1%notfound THEN
v_test := NULL;
END IF;
CLOSE c1;
RETURN v_test;
END;
I keep getting:
PLS-00382: expression is of wrong type
I believe from my initial return varchar2 statement. How do I allow the return to accept both varchar2 type and number type?
RETURN varchar2
You need to return the rowtype, but you are returning a scalar. VARCHAR2 cannot hold a row, it can hold only a string value.
Modify it to:
RETURN students%rowtype;
Demo using standard EMP table:
SQL> CREATE OR REPLACE FUNCTION studentName(
2 f_name IN VARCHAR2)
3 RETURN emp%rowtype
4 IS
5 v_test emp%rowtype;
6 CURSOR c1
7 IS
8 SELECT * FROM emp WHERE ename = f_name;

No errors.
NOTE : %ROWTYPE implies PL/SQL record type and PL/SQL types are not known to SQL. So you won't be able to use the function directly in plain SQL. You need to use SQL object type. Else you will get:
