基本操作：
查询：
SELECT [ALL | DISTINCT] select_expr, select_expr, ... FROM table_reference [WHERE where_condition] [GROUP BY col_list] [ORDER BY order_condition] [DISTRIBUTE BY distribute_condition [SORT BY sort_condition] ] [LIMIT number]
更新：
INSERT OVERWRITE|INTO TABLE tablename [PARTITION (partcol1=val1, partcol2=val2 ...)] [(col1,col2 ...)] select_statement FROM from_statement;
表关联：
join_table:
table_reference join table_factor [join_condition]
| table_reference {left outer|right outer|full outer|inner} join table_reference join_condition
table_reference:
table_factor
| join_table
table_factor:
tbl_name [alias]
| table_subquery alias
| ( table_references )
join_condition:
on equality_expression ( and equality_expression )
