SELECT语法：(基本)
*************************************************************
**********************************************************
SELECT [DISTINCT]
(column [{, column } ] )| *
FROM table [ { , table} ]
[ORDER BY column [ASC] | [DESC
[{ , column [ASC] | [DESC } ] ]
WHERE predicate [ { logical-connector predicate } ];
------------------------------------------------------
INSERT语法：
INSERT INTO table
[(column { ,column})]
VALUES
(columnvalue [{,columnvalue}]);
------------------------------------------------------
UPDATE语法：
UPDATE table
SET column = value [{, column = value}]
[ WHERE predicate [ { logical-connector predicate}]];
------------------------------------------------------
DELETE语法：
DELETE FROM table
[WHERE predicate [ { logical-connector predicate} ] ];
------------------------------------------------------
