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.

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。

所有的sp_都很有帮助，只是在网上浏览书籍

我在管理工作室一直使用的快捷键 F6 -结果和查询之间切换 Alt+X或F5-在查询中运行选中的文本，如果没有选中则运行整个窗口 Alt+T和Alt+D -结果在文本或网格分别

在恢复数据库用于测试或其他用途时非常有用。正确地重新映射登录ID:

EXEC sp_change_users_login 'Auto_Fix', 'Mary', NULL, 'B3r12-36'

sp_msforeachtable:运行带有'?替换为每个表名。如。

exec sp_msforeachtable "dbcc dbreindex('?')"

您最多可以为每个表发出3个命令

exec sp_msforeachtable
    @Command1 = 'print ''reindexing table ?''',
    @Command2 = 'dbcc dbreindex(''?'')',
    @Command3 = 'select count (*) [?] from ?'

此外,sp_MSforeachdb

TableDiff.exe

表差异工具允许您发现和协调源表和目标表或视图之间的差异。Tablediff实用程序可以报告模式和数据的差异。tablediff最受欢迎的特性是它可以生成一个脚本，您可以在目标上运行该脚本，以协调表之间的差异。

在SQL Server Management Studio (SSMS)中，您可以在对象资源管理器中突出显示对象名称，并按Ctrl-C将该名称复制到剪贴板。

不需要按F2或右键，重命名对象复制名称。

您还可以将对象从对象资源管理器拖放到查询窗口中。
