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;
