Few Examples on Dynamic SQL

Dynamic SQL


------------------------------------------------------------------
DECLARE
v_table_name varchar2(100) := 'test_dept';
v_stmt varchar2(1000);
BEGIN
v_stmt := 'insert into '||v_table_name||' values(50,''HR'')';
execute immediate v_stmt;
dbms_output.put_line(v_stmt);
END;

-------------------------------------------------------------------
DECLARE
type sob_record is record
(
name gl_sets_of_books.NAME%type,
currency_code gl_sets_of_books.CURRENCY_CODE%type,
set_of_books gl_sets_of_books.SET_OF_BOOKS_ID%type
);
v_stmt varchar2(1000);
curr sys_refcursor;
row_rec sob_record;
BEGIN
v_stmt := 'select name,currency_code,set_of_books_id from gl_sets_of_books where set_of_books_id=:input';
open curr for v_stmt using 2023;
loop
fetch curr into row_rec;
exit when curr%notfound;
dbms_output.put_line(row_rec.currency_code || '    '||row_rec.name);
end loop;
END;


-------------------------------------------------------------------------------

DECLARE
type status_record is record
(
cid xx_account_status_swap.customer_number%type,
acc_status xx_account_status_swap.new_account_status%type
);
type status_table is table of status_record;

v_stmt varchar2(1000);
curr sys_refcursor;
status_coll status_table;
BEGIN
v_stmt := 'select customer_number,new_account_status from xx_account_status_swap where success_status=:input';

open curr for v_stmt using 'P';
fetch curr bulk collect into status_coll;

for i in 1..status_coll.count loop
dbms_output.put_line(status_coll(i).cid||'   '||status_coll(i).acc_status);
end loop;

dbms_output.put_line('----------------------------------------------');
dbms_output.put_line(status_coll.count);
dbms_output.put_line('----------------------------------------------');
END;
