2)点开数据库结点--》安全性/登陆名--》右击“登陆名”--》新建登陆名--》SQL Server身份认证--》登陆名:admin,密码:333555,取消“强制实施密码策略”,默认数据库选择“InterLib”,如图(2)所示:
图(2)登陆名admin
3)在“用户映射”选项卡,勾选“InterLib”,数据库角色成员身份勾选“db_owner”,如图(3)所示:
图(3)设置admin的权限为“db_owner”
4)刷新数据库,即可看到“InterLib/安全性/用户”下,有admin。

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
