TRUNCATE TABLE

Description

This statement is used to clear the data of the specified table and partition grammar:

TRUNCATE TABLE [db.]tbl[ PARTITION(p1, p2, ...)];

illustrate:

The statement clears the data, but leaves the table or partition.
Unlike DELETE, this statement can only clear the specified table or partition as a whole, and cannot add filter conditions.
Unlike DELETE, using this method to clear data will not affect query performance.
The data deleted by this operation cannot be recovered.
When using this command, the table status needs to be NORMAL, that is, operations such as SCHEMA CHANGE are not allowed.
This command may cause the ongoing load to fail

Clear the table tbl under example_db
```
TRUNCATE TABLE example_db.tbl;
```
Empty p1 and p2 partitions of table tbl
```
TRUNCATE TABLE tbl PARTITION(p1, p2);
```
