问题
For my job I often have to script out a table with all its keys, constraints and Triggers (basically a full script to recreate the table) from a Microsoft SQL 2008 server.I also have to do this for procedures and triggers. What I do now is open SSMS right click the object and select script to and select to script it to a file. So if I have 3 procedures to do and 10 tables and 1 trigger I end up doing this 14 times . What I would like is a powershell script that I could feed a list of objects to and then it would go and use SMO to script each on out to an individual file.
Thanks for the help

Here is a PowerShell function I use whenever I have to script a database. It should be easy to modify just to scripts the objects you need.
function SQL-Script-Database
{
<#
.SYNOPSIS
Script all database objects for the given database.
.DESCRIPTION
This function scripts all database objects (i.e.: tables, views, stored
procedures, and user defined functions) for the specified database on the
the given server\instance. It creates a subdirectory per object type under
the path specified.
.PARAMETER savePath
The root path where to save object definitions.
.PARAMETER database
The database to script (default = $global:DatabaseName)
.PARAMETER DatabaseServer
The database server to be used (default: $global:DatabaseServer).
.PARAMETER InstanceName
The instance name to be used (default: $global:InstanceName).
.EXAMPLE
SQL-Script-Database c:\temp AOIDB
#>
param (
[parameter(Mandatory = $true)][string] $savePath,
[parameter(Mandatory = $false)][string] $database = $global:DatabaseName,
[parameter(Mandatory = $false)][string] $DatabaseServer = $global:DatabaseServer,
[parameter(Mandatory = $false)][string] $InstanceName = $global:InstanceName
)
try
{
if (!$DatabaseServer -or !$InstanceName)
{ throw "`$DatabaseServer or `$InstanceName variable is not properly initialized" }

Here's a script to backup an individual object. Simply pass the object name to the function:
