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。

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
