# Proposed changes
mtmv task use original query stmt so that user can set var more flexible,
for example set query_timeout, exec_mem_limit etc
though ``CREATE MATERIALIZED VIEW`` statement
```
CREATE MATERIALIZED VIEW multi_mv
BUILD IMMEDIATE
REFRESH COMPLETE
start with "2022-10-27 19:35:00"
next 60 second
KEY(username)
DISTRIBUTED BY HASH (username) buckets 1
PROPERTIES ('replication_num' = '1')
AS
select /*+set_var(query_timeout=1000)*/ t_user.username, t_user_pv.pv from
t_user, t_user_pv where t_user.id=t_user_pv.id;
```
mtmv task will use the original stmt when insert data to table
```
select /*+set_var(query_timeout=1000)*/ t_user.username, t_user_pv.pv from
t_user, t_user_pv where t_user.id=t_user_pv.id;
```
instead of
```
select t_user.username, t_user_pv.pv from t_user, t_user_pv where
t_user.id=t_user_pv.id;
```
