Hi, wangxiaojing, I have an issues for this PR.
Currently the ```truncate table``` works fine in the situation that current
table is in the corresponding database session. But it doesn't work in the
scenario which the table is not in the corresponding database session.
What I mean is :
Assume we have two database:``` default```, ``` dw```. A table named
```test_table``` in database ```dw```
By default we login as default database session. So I runï¼
```
use dw;
truncate table test_table [partions......]; is OK.
```
If I just use the default database ```default``` to run:
```
use default;
truncate table dw.test_table;
```
It will throw exception
```
Failed to parse: truncate table dw.test_table.
line 1:17 missing EOF at '.' near 'dw'
```
It's a bug when parsing the ```truncate table xxx```
It would be nicer to fix it : )
