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

下面是一些我喜欢的SQL Management Studio隐藏特性。

我喜欢的一点是，如果你在高亮显示信息时按住ALT键，你可以选择柱状信息，而不仅仅是整行。

在SQL Management Studio中，你有预定义的快捷键:

Ctrl+1运行sp_who Ctrl+2运行sp_lock Alt+F1运行sp_help Ctrl+F1运行sp_helptext

因此，如果您在编辑器中突出显示表名并按Alt+F1，它将显示表的结构。

删除到数据库的所有连接:

Use Master
Go

Declare @dbname sysname

Set @dbname = 'name of database you want to drop connections from'

Declare @spid int
Select @spid = min(spid) from master.dbo.sysprocesses
where dbid = db_id(@dbname)
While @spid Is Not Null
Begin
        Execute ('Kill ' + @spid)
        Select @spid = min(spid) from master.dbo.sysprocesses
        where dbid = db_id(@dbname) and spid > @spid
End

我想推荐一个免费的插件SSMS工具包，它有很多功能，如

代码片段

你不再需要自己输入SELECT * FROM。只需输入SSF并按enter(可以自定义为任何其他键)。我更喜欢Tab)。其他有用的代码片段很少

SSC +标签-选择计数(*)从

SST + tab -选择TOP 10 * FROM

S +选项卡-选择

I + tab -插入

U + tab - UPDATE

W + tab - WHERE

OB + tab - ORDER BY

这样的例子不胜枚举。您可以使用SSMS Tools Pack菜单检查和自定义整个列表

执行日志记录

您是否意识到您可以保存几天前编写的临时查询，这样您就不需要再次重新发明轮子了?SSMS Tools包保存您的所有执行历史，您可以根据日期或查询中的任何文本进行搜索。

搜索数据库数据

这个特性可以帮助您搜索字符串在整个数据库中的出现情况，并显示表名和列名以及出现的总数。您可以通过在对象资源管理器中右键单击数据库并选择搜索数据库数据来使用此功能。

SQL格式

将所有关键字设置为大写或小写字母。右键单击查询窗口并选择格式文本。您可以在SSMS工具菜单中设置快捷键。但它缺乏对齐功能。

CRUD SP生成

右键单击一个表，SSMS Tools - > Create CRUD生成插入、更新、删除和选择SP。SP的内容可以使用SSMS Tools菜单定制。

Misc

其他特性很少

以网格模式搜索结果。从结果集，表和数据库生成插入脚本。执行计划分析器。在多个数据库中运行一个脚本。

根据单个语句中管道分隔的id字符串返回结果(替代传递xml或首先将分隔的字符串转换为表)

例子:

DECLARE @nvcIDs nvarchar(max)
SET @nvcIDs = '|1|2|3|'

SELECT C.*
FROM tblCompany C
WHERE @nvcIDs LIKE '%|' + CAST(C.CompanyID as nvarchar) + '|%'

     FOR XML PATH(''), TYPE
  )  AS Statement_Text

 , o.modify_date 

 FROM sys.all_sql_modules a

 ORDER BY  4 desc
