i want to create a view from the procedure like the
following one,
It creates the proc but while running it show invalid
column name please help me;
create or replace procedure asho2005.mock_pro(
fin_fr_dt in date, fin_to_dt in date) is
     ffdt date;
     ftdt date;
begin
select to_date(fin_fr_dt,'dd-mm-yyyy') into ffdt
t from dual;
select to_date(fin_to_dt,'dd-mm-yyyy') into ftdt
t from dual;
execute immediate 'create or replace view mock_vu
vu as select a.amt from cbtran a where chq_dt > ffdt
and chq_dt <ftdt';
end;Hallo,
your problem is , that execute immediate does't recognize ffdt
You have to concatenate literals
create or replace procedure asho2005.mock_pro( fin_fr_dt in date, fin_to_dt in date) is
ffdt date;
ftdt date;
begin
select to_date(fin_fr_dt,'dd-mm-yyyy') into ffdt from dual;
select to_date(fin_to_dt,'dd-mm-yyyy') into ftdt from dual;
execute immediate 'create or replace view mock_vu as select a.amt from cbtran a where chq_dt > '''||ffdt||''' and chq_dt <'''||ftd||'''';
end; BTW, your view doesn't return any rows
ffdt and < ffdt :-)
Besides that , it's a very very bad method!
You must not create views in runtime. Use of literals results in hard parsing .
The performance will be poor.
You have to create view in design time, and then simply use select:
select * from mock_vu where chq_dt > (your_date) and something else
