…th `use db` and enable sql cache (apache#44782)

### What problem does this PR solve?

It will return wrong result when running same sql in different db with
`enable_sql_cache=true`

for example, the `db1` and `db2` has the same table `tbl` but the data
are not equals,
if execute the below sql in `db1` and cache the result, then execute it
in `db2`, it will return the wrong result
```sql
select count(*) from tbl
```
