[spark-3907][sql] add truncate table support
JIRA issue: [SPARK-3907]https://issues.apache.org/jira/browse/SPARK-3907
add turncate table support
TRUNCATE TABLE table_name [PARTITION partition_spec];
partition_spec:
: (partition_col = partition_col_value, partition_col =
partiton_col_value, ...)
Removes all rows from a table or partition(s). Currently target table
should be native/managed table or exception will be thrown. User can specify
partial partition_spec for truncating multiple partitions at once and omitting
partition_spec will truncate all partitions in the table.
