1. 前言

SQL Server一般是在安装过程中进行相关的配置，安装完成之后，再去修改有一些配置就比较麻烦，比如更改SQL Server实例级别的排序规则。但在Linux下，安装过程并没有很多可以配置的步骤，安装步骤变得很简单，更多的配置可以通过/opt/mssql/bin/mssql-conf工具进行。

2. 环境

Linux: CentOS 7.4，SQL Server 2017 (RC2) - 14.0.900.75 (X64)

3. 更改SQL Server排序规则

步骤如下：
  1. 备份所有用户数据库。（如果是刚刚安装好的实例没有用户数据库可以跳过这一步。）
  2. 停止数据库实例
  3. 运行/opt/mssql/bin/mssql-conf set-collation命令修改排序规则
  4. 启动数据库实例
  5. 还原用户数据库（没有用户数据库可跳过）

下面就来演示下。

查询当前数据库实例的排序规则

1> SELECT CONVERT(NVARCHAR(50),SERVERPROPERTY('Collation'));

2> GO

--------------------------------------------------

SQL_Latin1_General_CP1_CI_AS

Code-1： 更改前的数据库实例排序规则

使用sp_detach_db存储过程来分离数据库。如果提示数据库正在使用，可以设置数据库为单用户模式，或者干脆就把数据库实例重启。

1> exec sp_detach_db db1;

2> go

1> exec sp_detach_db AdventureWorks2014;

2> go

1> exec sp_detach_db AdventureWorks2017;

2> go

Code-2：分离用户数据库

在shell 下：

[root@134test ~]# systemctl stop mssql-server

[root@134test ~]# /opt/mssql/bin/mssql-conf set-collation

Enter the collation: Chinese_PRC_CI_AS
