Oracle数据库SQL句子入门攻略
Oracle数据库作为全球抢先的企业级数据库办理体系,其SQL(结构化查询言语)句子在数据库办理和使用开发中扮演着至关重要的人物。本文将为您具体介绍Oracle数据库SQL句子的根底知识,协助您快速入门。
一、Oracle SQL句子概述
SQL句子是用于操作Oracle数据库的东西,包括数据查询、数据刺进、数据更新和数据删去等。Oracle SQL句子遵从ANSI SQL规范,一起也包括Oracle特有的扩展功用。
二、Oracle SQL句子分类
Oracle SQL句子首要分为以下几类:
DML(数据操作言语)
SELECT:用于查询数据库中的数据。
INSERT:用于向数据库中刺进新数据。
UPDATE:用于更新数据库中的现有数据。
DELETE:用于删去数据库中的数据。
DDL(数据界说言语)
CREATE:用于创立数据库目标,如表、视图等。
ALTER:用于修正数据库目标的结构。
DROP:用于删去数据库目标。
DCL(数据操控言语)
GRANT:用于颁发用户或人物权限。
REVOKE:用于回收用户或人物的权限。
TCL(业务操控言语)
COMMIT:用于提交业务。
ROLLBACK:用于回滚业务。
SAVEPOINT:用于设置保存点。
三、常用Oracle SQL句子示例
1. 数据查询(SELECT)
SELECT句子用于从数据库中检索数据,以下是一个简略的查询示例:
SELECT column1, column2
FROM table_name
WHERE condition;
2. 数据刺进(INSERT)
INSERT句子用于向数据库中刺进新数据,以下是一个简略的刺进示例:
INSERT INTO table_name (column1, column2)
VALUES (value1, value2);
3. 数据更新(UPDATE)
UPDATE句子用于更新数据库中的现有数据,以下是一个简略的更新示例:
UPDATE table_name
SET column1 = value1, column2 = value2
WHERE condition;
4. 数据删去(DELETE)
DELETE句子用于删去数据库中的数据,以下是一个简略的删去示例:
DELETE FROM table_name
WHERE condition;
