SQLCMD

如果您有脚本需要反复运行，但必须更改轻微的细节，那么在sqlcmd模式下运行ssms非常棒。sqlcmd命令行也非常漂亮。

我最喜欢的特点是:

你需要设置变量。适当的变量，不需要跳过sp_exec圈您可以一个接一个地运行多个脚本这些脚本可以引用“外部”脚本中的变量

Red Gate的Simpletalk没有再滔滔滔滔地说什么，而是对sqlcmd - sqlcmd工作台做了一个很棒的总结。Donabel Santos也有一些很棒的SQLCMD示例。

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。

在SQL Server 2005中，您不再需要运行sp-blocker-pss80存储过程。相反，你可以这样做:

exec sp_configure 'show advanced options', 1;
reconfigure;
go
exec sp_configure 'blocked process threshold', 30;
reconfigure;

然后，您可以启动SQL跟踪，并在“错误和警告”组中选择“阻塞”流程报告事件类。详情请点击这里。
