SQLServer创建用户自定义数据库用户

创建用户自定义数据库用户注意事项
如果已忽略 FOR LOGIN，则新的数据库用户将被映射到同名的SQL Server登录名。
默认架构将是服务器为此数据库用户解析对象名时将搜索的第一个架构。 除非另外指定，否则默认架构将是此数据库用户创建的对象所属的架构。
如果用户具有默认架构，则将使用默认架构。 如果用户不具有默认架构，但该用户是具有默认架构的组的成员，则将使用该组的默认架构。 如果用户不具有默认架构而且是多个组的成员，则该用户的默认架构将是具有最低principle_id的Windows组的架构和一个显式设置的默认架构。（不可能将可用的默认架构之一显式选作首选架构。）如果不能为用户确定默认架构，则将使用 dbo 架构。
DEFAULT_SCHEMA可在创建它所指向的架构前进行设置。
在创建映射到证书或非对称密钥的用户时，不能指定DEFAULT_SCHEMA。
如果用户是sysadmin固定服务器角色的成员，则忽略DEFAULT_SCHEMA的值。sysadmin固定服务器角色的所有成员都有默认架构dbo。
WITHOUT LOGIN子句可创建不映射到SQL Server登录名的用户。它可以作为guest连接到其他数据库。可以将权限分配给这一没有登录名的用户，当安全上下文更改为没有登录名的用户时，原始用户将收到无登录名用户的权限。
只有映射到Windows主体的用户才能包含反斜杠字符 ()。
不能使用CREATE USER创建guest用户，因为每个数据库中均已存在guest用户。可通过授予guest用户CONNECT权限来启用该用户，如下所示：
可以在 sys.database_principals 目录视图中查看有关数据库用户的信息。
使用SSMS数据库管理工具创建用户自定义数据库用户
1、连接服务器-》在对象资源管理器窗口选择数据库-》展开数据库-》展开安全性-》展开用户-》右键点击用户-》选择新建。

2、在数据库用户-新建弹出框-》点击常规-》选择用户类型-》输入用户名-》选择登录名-》选择用户所属架构。

3、在数据库用户-新建弹出框-》选择用户所拥有的架构。

4、在数据库用户-新建弹出框-》点击成员身份-》选择数据库成员身份。

5、在数据库用户-新建弹出框-》点击搜索选择一个安全对象-》选择安全对象以后选择安全对象所拥有的权限。

6、在数据库用户-新建弹出框-》选择扩展属性-》输入注释名称-》输入注释值-》点击确定。

7、不需要刷新即可在对象资源管理器查看创建结果。

语法注释
–database_name–数据库名称–user_name–指定在此数据库中用于识别该用户的名称。user_name 为 sysname。 –它的长度最多是 128 个字符。在创建基于Windows主体的用户时，除非指定其他用户名，否则Windows主体名称将成为用户名。–login_name–指定要为其创建数据库用户的登录名。login_name必须是服务器中的有效登录名。 –可以是基于Windows主体（用户或组）的登录名，也可以是使用SQL Server身份验证的登录名。–当此SQL Server登录名进入数据库时，它将获取正在创建的这个数据库用户的名称和ID。–在创建从 Windows 主体映射的登录名时，请使用格式 [<domainName><loginName>]。 –如果CREATE USER语句是SQL批处理中唯一的语句，则Windows Azure SQL Databas 将支持WITH LOGIN子句。 –如果CREATE USER语句不是SQL批处理中唯一的语句或在动态SQL中执行，则不支持 WITH LOGIN 子句。–with default_schema=architecture_name;–指定服务器为此数据库用户解析对象名时将搜索的第一个架构。–allow_encrypted_value_modifications={ on | off } –适用范围：SQL Server 2016 (13.x) 到SQL Server 2017、SQL Database。–取消在大容量复制操作期间对服务器进行加密元数据检查。这使用户能够在表或数据库之间大容量复制加密数据，–而无需对数据进行解密。默认为 OFF。–without login–指定不应将用户映射到现有登录名。–asymmetric KEY asym_key_name–适用范围：SQL Server 2008到SQL Server 2017、SQL Database。–指定要为其创建数据库用户的非对称密钥。–certificate certificate_name–适用范围：SQL Server 2008到SQL Server 2017、SQL Database。–指定要为其创建数据库用户的证书。–description_name–用户自定义用户注释名称。–description_value–用户自定义用户注释值。
