SQL Server有哪些隐藏特性?

例如,没有文档的系统存储过程,做一些非常有用但没有足够文档的事情的技巧?


答案

感谢大家的精彩回答!

存储过程

sp_msforeachtable: Runs a command with '?' replaced with each table name (v6.5 and up) sp_msforeachdb: Runs a command with '?' replaced with each database name (v7 and up) sp_who2: just like sp_who, but with a lot more info for troubleshooting blocks (v7 and up) sp_helptext: If you want the code of a stored procedure, view & UDF sp_tables: return a list of all tables and views of database in scope. sp_stored_procedures: return a list of all stored procedures xp_sscanf: Reads data from the string into the argument locations specified by each format argument. xp_fixeddrives:: Find the fixed drive with largest free space sp_help: If you want to know the table structure, indexes and constraints of a table. Also views and UDFs. Shortcut is Alt+F1

获得垂直格式的列标题列表:

复制网格结果中的列名

工具-选项-查询结果- SQL Server -结果网格 勾选“在复制或保存结果时包含列标题”

此时,您需要建立一个新的连接,然后运行查询

现在,当您从网格复制结果时,您将获得列标题

也 然后将结果复制到excel

只复制col标头

粘贴特殊(不能与复制区域重叠)

蜱虫“转置”

OK

[你可能希望在这里添加一个","并自动填充]

您有一个垂直格式的列的即时列表

这里有一些未记录的命令:未记录但很方便的SQL server Procs和DBCC命令

这不是一个隐藏的功能,而是在管理工作室的工具\选项\键盘下设置键映射: Alt+F1默认为sp_help“选定的文本”,但我不能没有添加Ctrl+F1为sp_helptext“选定的文本”

Persisted-computed-columns

计算列可以帮助您将运行时计算成本转移到数据修改阶段。计算列与行其余部分一起存储,当计算列上的表达式与查询匹配时,将透明地使用它。您还可以在PCC上构建索引,以加快表达式的过滤和范围扫描。

以下是我最喜欢的一些东西:

在sp2 -工具/选项/脚本下增加了脚本选项

使用模式的新安全性—创建两个模式:user_access、admin_access。把你的用户过程放在一个,你的管理过程放在另一个,像这样:user_access。showList, admin_access.deleteUser。将模式上的EXECUTE授权给你的应用用户/角色。不再一直授予EXECUTE。

使用内置加密函数、视图(为了表示而解密)和带触发器的基表(在插入/更新时加密)进行加密。

替代Kolten的sp_change_users_login:

ALTER USER wacom_app WITH LOGIN = wacom_app
