SQL Server 数据库 CREATE BROKER PRIORITY 创建服务代理优先级语法

摘要：

在SQL Server中，服务代理（Service Broker）是一种强大的消息传递系统，用于在数据库实例内部或跨数据库实例之间进行异步消息传递。服务代理优先级是配置服务代理行为的一个重要方面，它决定了消息在服务代理队列中的处理顺序。本文将深入解析SQL Server中的CREATE BROKER PRIORITY语法，探讨如何创建和管理服务代理优先级。

一、

服务代理优先级是SQL Server服务代理系统中的一个关键概念。它允许数据库管理员（DBA）根据业务需求调整消息的处理顺序，确保高优先级任务能够及时完成。本文将围绕CREATE BROKER PRIORITY语法展开，详细介绍其使用方法、配置选项以及在实际应用中的注意事项。

二、CREATE BROKER PRIORITY语法概述

CREATE BROKER PRIORITY语句用于创建一个新的服务代理优先级。以下是CREATE BROKER PRIORITY语句的基本语法：

```sql

CREATE BROKER PRIORITY [schema_name.]priority_name

WITH (LOW_PRIORITY = ON|OFF,

HIGH_PRIORITY = ON|OFF,

IO_PRIORITY = ON|OFF,

MAX_QUEUE_READERS = integer_value,

MAX_QUEUE_READERS_PER_TRANSACTION = integer_value,

MAX_QUEUE_READERS_PER_JOB = integer_value,

MAX_QUEUE_READERS_PER_SERVICE = integer_value,

MAX_QUEUE_READERS_PER_SERVICE_PER_JOB = integer_value,
