Oracle 视图、存储过程、函数、序列、索引、同义词、触发器
在Oracle数据库中,创建各种对象(如视图、存储过程、函数、序列、索引、同义词和触发器)的SQL语句如下:
- 视图(View):
CREATE OR REPLACE VIEW view_name AS
SELECT column1, column2
FROM table_name
WHERE condition;
- 存储过程(Procedure):
CREATE OR REPLACE PROCEDURE proc_name (param1 IN/OUT/IN OUT type, ...) IS
BEGIN
-- 过程执行语句
END;
- 函数(Function):
CREATE OR REPLACE FUNCTION func_name (param1 IN/OUT/IN OUT type, ...) RETURN return_type IS
BEGIN
-- 函数执行语句
RETURN return_value;
END;
- 序列(Sequence):
CREATE SEQUENCE seq_name
START WITH initial_value
INCREMENT BY increment_value
MINVALUE minimum_value
MAXVALUE maximum_value
CYCLE | NOCYCLE
CACHE cache_size;
- 索引(Index):
CREATE INDEX idx_name ON table_name (column1, column2, ...);
- 同义词(Synonym):
CREATE OR REPLACE SYNONYM syn_name FOR object_name;
- 触发器(Trigger):
CREATE OR REPLACE TRIGGER trg_name
BEFORE | AFTER | INSTEAD OF event
ON table_name
FOR EACH ROW
BEGIN
-- 触发器执行语句
END;
请根据实际需求替换view_name
, table_name
, column1
, column2
, condition
, proc_name
, func_name
, param1
, return_type
, return_value
, seq_name
, initial_value
, increment_value
, minimum_value
, maximum_value
, cycle
, cache_size
, idx_name
, object_name
, syn_name
, trg_name
, 和 event
等占位符。
