PLSQL script not working with passing multiple values into IN() caluse - plsql

Question

I am very new in PLSQL, i want to pass an array of number into IN() clause value, But Sqldeveloper throw following error messages:
Error report -
ORA-06550: line 11, column 60:
PLS-00382: expression is of wrong type
ORA-06550: line 11, column 53:
PL/SQL: ORA-22905: cannot access rows from a non-nested table item
ORA-06550: line 10, column 4:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
This is my code :
DECLARE
TYPE sc IS TABLE OF transactionhistory.NBSUBCOMPANY%TYPE INDEX BY PLS_INTEGER;
arr sc;
BEGIN
arr(0) := 000;
arr(1) := 111;
arr(2) := 222;
arr(3) := 333;
select count(th.CHCARDNUMBER) as transactions from transactionhistory th INNER JOIN cards ch on ch.NBATTMID=th.NBATTMID where th.dtdate>=to_date('01-oct-2016','dd-mon-yyyy') and th.dtdate<to_date('01-nov-2016','dd-mon-yyyy')
and ch.NBSUBCOMPANY IN (select column_value from table (arr))
and ((th.CHTRANSTYPE in ('2940', '2916', '2941', '2942', '2943', '2944', '2945', '2902', '2917', '2925') and th.NBBASEAMT < 0) or (th.CHTRANSTYPE in ('2922', '2923', '2926', '2950', '2951', '2952', '2953', '2954', '2955') and th.NBBASEAMT > 0) or (th.CHTRANSTYPE in ('1101', '1102', '1104', '1105', '1106', '1107', '1109') and th.BASEII_STATUS = 'C') or th.CHTRANSTYPE not in ('2940', '2916', '2941', '2942', '2943', '2944', '2945', '2902', '2917', '2925', '2922', '2923', '2926', '2950', '2951', '2952', '2953', '2954', '2955', '1101', '1102', '1104', '1105', '1106', '1107', '1109'));
END;
Please suggest me how can i pass this.

Answer 1

You will need to have a workaround.
SQL doesn't support local collection types to be used in the way you want.
Sample Procedure below which will help in resolving
CREATE OR REPLACE type TEST_TYPE
IS
TABLE OF NUMBER;
You will need to create a type in the database for this to work. Can be created inside a package, if you have one.
DECLARE
TEST_VAR TEST_TYPE := TEST_TYPE();
BEGIN
TEST_VAR.extend(1);
TEST_VAR(TEST_VAR.last) := 222;
TEST_VAR.extend(1);
TEST_VAR(TEST_VAR.last) := 333;
FOR rec IN
(SELECT column_value
FROM TABLE(TEST_VAR)
)
LOOP
dbms_output.put_line(rec.column_value);
END LOOP;
END;
Output
222
333
This way, you can use select column_value from table(test_var) for your IN() clause.
Also, you don't necessarily need to follow the extend(i) part. you can simply do the below as well
TEST_VAR TEST_TYPE := TEST_TYPE(222,333);
Have a read - local collection types not allowed in SQL statements

Answer 2

You can use MEMBER OF clause. See below:
As #Sudipta mentioned you cannot use a collection decalred in PLSQL block as you are doing, you need to declare it outside of the PLSQL block.
CREATE OR REPLACE TYPE sc IS TABLE OF NUMBER;
and then
DECLARE
-- TYPE sc IS TABLE OF NUMBER INDEX BY PLS_INTEGER;
arr sc:=sc();
num number;
BEGIN
arr.extend(4);
arr(1) := 0;
arr(2) := 1;
arr(3) := 2;
arr(4) := 3;
Select count(1)
into num
from employee
-- You can use either commented one or uncommented one. your choice.
--where employee_id in (select column_value from table(arr));
where employee_id member of arr;
END;
