   # Proposed changes
   
   Issue Number: close #xxx
   
   support insert the ret-value of a query into a table with `partition`, `with 
label`, `cols` tags:
   Like:
   ```sql
   insert into t partition (p1, p2) with label label_1 (c1, c2, c3) [hint1, 
hint2] with cte as (select * from src) select k1, k2, k3 from cte
   ```
   
   We make class named InsertIntoTableCommand to describe the command. Add the 
insert into schema to statementCtx so than we can check if the query's outputs 
are compatible the target table schema.
   
   When planned the sql, we create datasink in the run() in the command and 
init it. Then we run a transaction to insert the data.
   
   Describe your changes.
