如何使用SMO获取和设置SQL Server 2008表的description属性？

Question

How can I get and set the description property of a SQL Server 2008 table using Microsoft.SqlServer.Management.Smo? I have seen documentation on how to do this at the column level but not at the table level.

Answer 1

I was able to do the following in powershell:

$s = new-object microsoft.sqlserver.management.smo.server '.';
$db = $s.Databases['AdventureWorks2012'];
$t = $db.Tables | where {$_.Name -eq 'Address'};
$t.ExtendedProperties['MS_Description']; # will print current value
$t.ExtendedProperties['MS_Description'].Value = 'new value';
$t.ExtendedProperties['MS_Description'].Alter(); #persist the new value to the database

Answer 2

Can't remember: Is the description in the Extended Properties? If so, TableViewTableTypeBase.ExtendedProperties will have your description for you (which Microsoft.SqlServer.Management.Smo.Table inherits)

Answer 3

It is in extended properties, I do it this way:

string Description = table.ExtendedProperties["MS_Description"].Value.ToString();

You need to specify which extended property you need in string - thats why you could not find it so easily.
