How to script all child/parent tables given a specific table name? - sql-server

Question

I need to provide my Powershell script a specific table name and then generate the DDL in sorted order for all child/parent tables. In the image below, I have attached an example schema where the green bubble indicates what the script is currently producing and the red bubble indicates the DDL that is currently missing for the desired output.
$InstanceName = 'SERVER_NAME'
[reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | out-null
$server = New-Object ('Microsoft.SqlServer.Management.Smo.Server') $InstanceName;
$db = $server.Databases["DATABASE_NAME"]
# Create an instance of the dependency walker class
$dw = New-Object Microsoft.SqlServer.Management.Smo.DependencyWalker($server)
$tables = $db.Tables['tbl_C1']
# Define an empty array to store the sorted tables
$sortedTables = #()
# Loop through the tables
foreach ($table in $tables) {
# Get the dependencies for the current table
$dependencies = $dw.DiscoverDependencies($table.Urn, $false)
# Add the current table to the array of sorted tables
$sortedTables += $table
# Loop through the dependencies
foreach ($dependency in $dependencies) {
# Check if the dependency is a table
if ($dependency.Type -eq "Microsoft.SqlServer.Management.Smo.Table") {
# Check if the dependency is not already in the array of sorted tables
if ($sortedTables -notcontains $dependency.Urn.GetSmoObject()) {
# Add the dependency to the array of sorted tables
$sortedTables += $dependency.Urn.GetSmoObject()
}
}
}
}
# Loop through the sorted tables and script them out
foreach ($table in $sortedTables) {
$scripter = new-object Microsoft.SqlServer.Management.Smo.Scripter($server)
$scripter.Options.ScriptDrops = $false
$scripter.Options.WithDependencies = $true
$scripter.Options.Indexes = $false
$scripter.Options.DriAll = $true
$scripter.Options.ScriptData = $false
$scripter.Options.SchemaQualify = $true
$scripter.Options.ScriptSchema = $true
$scripter.Options.IncludeHeaders = $true
$scripter.Script($table)
}
