CMS: Find all Databases on all Servers with Table "A" without Column "B"

This CMS (Central Management Server) code will tell you, for all databases in all servers, which tables of a given name don't have a column of a given name.

-- For all databases in all servers that have a "Customer" table, which ones don't have a "ZipCode" column? 
set nocount on

    declare @Schema sysname     set @Schema = 'dbo'
    declare @Table  sysname     set @Table  = 'Customer'
    declare @Column sysname     set @Column = 'ZipCode'

    declare @Sql nvarchar(4000)

    set @Sql = 'use [?]

Use Central Management Servers to Alter a Column in All Servers

The "Central Management Servers" functionality of SQL Server Management Studio is an excellent way to apply the same code to every server. By "every server", I mean groups of servers that you define: you might have different servers in folders named "Production", "Development", "QA", "SQL Server 2000", etc. It just depends on your needs.

To get to the "Central Management Servers" pane in SSMS, simply select the "View, Registered Servers" menu item. After you've set up your servers, you can execute queries against every database in every server. The example below changes the width of a column in a table. Note that in this example, we look for only databases whose name begins with "DB100", we exclude read-only databases, and we specify the schema, table, and column name we want to modify. The code also checks that the length isn't already set to the value we want, to avoid unnecessary noise in the output. This code is compatible with SQL Server 2000 and later (hence the use of "syscolumns", etc.)
