I want to run stored procedure in a loop - db2

Question

I want to run sp in a loop .
I am using db2.
For ex if there are 10 rows in my table and 8 rows contain status as approved ,I want those 8 rows to be executed 1 by 1 through my sp .
I have used this method
declare #v_count INT;
declare #row_count INT;
declare #v_actorCNUM CHAR(10);
declare #v_sessID CHAR(32);
declare #v_taskID SMALLINT;
declare #v_dest_citrusSCID INTEGER;
declare #v_src_citrusSCID INTEGER;
declare #v_CtrCnum CHAR(10);
declare #v_dest_security_grp_nm varchar(100);
declare #v_src_security_grp_nm varchar(100);
SET #v_count=1;
DECLARE GLOBAL TEMPORARY TABLE csc_trfr
(
Row_id INT GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1),
CNTRCTR_CNUM CHAR(10) NOT NULL ,
DEST_CSC_NM CHAR(30) ,
SRC_CSC_NM CHAR(30) ,
DEST_GRP_NM VARCHAR(100) ,
SRC_GRP_NM VARCHAR(100) ,
USR_LST_UPDT_ID CHAR(10)
) WITH REPLACE ON COMMIT PRESERVE ROWS NOT lOGGED;
insert into session.csc_trfr (cntrctr_cnum,dest_csc_nm,src_csc_nm,dest_grp_nm,src_grp_nm,usr_lst_updt_id)
select cntrctr_cnum,dest_csc_nm,source_csc_nm,dest_grp_nm,src_grp_nm,usr_lst_updt_id from citrus.cntrctr_csc_trfr where trfr_status='Approved';
select count(*) into #row_count from citrus.cntrctr_csc_trfr where trfr_status='Approved';
while #v_count<=#row_count
BEGIN
SET #v_actorCNUM=select usr_lst_updt_id from session.csc_trfr order by row_id offset #v_count rows fetch next 1 rows only;
SET #v_taskID=166;
set #v_dest_citrusSCID =select citrus_suprt_id from citrus.citrus_suprt_cntr where citrus_suprt_nm=(select DEST_CSC_NM from session.csc_trfr order by row_id offset #v_count rows fetch next 1 rows only );
set #v_src_citrusSCID=select citrus_suprt_id from citrus.citrus_suprt_cntr where citrus_suprt_nm=(select SRC_CSC_NM from session.csc_trfr order by row_id offset #v_count rows fetch next 1 rows only );
set #v_CtrCnum=select cntrctr_cnum from session.csc_trfr order by row_id offset #v_count rows fetch next 1 rows only;
set #v_dest_security_grp_nm =select DEST_GRP_NM from session.csc_trfr order by row_id offset #v_count rows fetch next 1 rows only;
set #v_src_security_grp_nm=select DEST_GRP_NM from session.csc_trfr order by row_id offset #v_count rows fetch next 1 rows only;
call citrus.BAC020_cntrctrCSCTrfr(#v_actorCNUM,'',#v_taskID,#v_dest_citrusSCID,#v_src_citrusSCID,#v_CtrCnum,#v_dest_security_grp_nm,#v_src_security_grp_nm,?,?,?);
#v_count=#v_count+1;
end
I have name script as test.sql and executing script like :
db2 -tvf test.sql
but I am getting sql error.
DB21034E The command was processed as an SQL statement because it was not a
valid Command Line Processor command. During SQL processing it returned:
SQL0104N An unexpected token "declare #v_actorCNUM CHAR" was found
following "BEGIN-OF-STATEMENT". Expected tokens may include: "".
LINE NUMBER=1. SQLSTATE=42601
error is same for all variables.
My code is count the rows in cntctr_csc_trfr table where transfer status is approved .and then I am putting those rows in temp table .For each row in temp table I want to run stored procedure.

I had the same problem
Here is an example :
use database1
go
DECLARE #RC int
DECLARE #RequestCode nvarchar(50)
Declare column_cursor Cursor For
select columnName from table_name
OPEN column_cursor
Fetch Next From column_cursor into #RequestCode
While ##Fetch_Status=0 Begin
EXECUTE #RC = [dbo].[stored_procedure_name] #RequestCode
Fetch Next From column_cursor Into #RequestCode
End
Close column_cursor
Deallocate column_cursor
