Gerando scripts do banco de dados por PowerShell – Passo 1

Tento já explicado como utilizar o SMO para gerar o scripts do SQL Server por .NET, agora teremos a alternativa com PowerShell:

# Referências
[void][system.reflection.assembly]::loadfrom("C:\Program Files\Microsoft SQL Server\100\SDK\Assemblies\Microsoft.SqlServer.Smo.dll")

# Objetos
$srv = new-object Microsoft.SqlServer.Management.Smo.Server(".\SQLEXPRESS")

$db = $srv.Databases["DemoAspNet"]

# 1. Gerando o Script do banco de dados
$db.Script() | Out-File "C:\Temp\DemoAspNet.sql"

# 2. Gerando o Script das tabelas do banco de dados
$db.Tables | % { $_.Script() } | Out-File "C:\Temp\DemoAspNet_Tables.sql"

# 3. Script com o GO entre as linhas (Forma 1)
$go = "`nGO`n"
$db.Tables | % { $_.Script() | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_Tables.sql"

# 4. Script com o GO entre as linhas (Forma 2)
$go = "
GO
"
$db.Tables | % { $_.Script() | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_Tables.sql"

# 5. Gerando o DROP das tabelas
$options = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions
$options.ScriptDrops = $TRUE

$go = "`nGO`n"
$db.Tables | % { $_.Script($options) | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_TableDrop.sql"

# 6. Gerando o script das tabelas com as Primary Keys
$options = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions
$options.DriPrimaryKey = $TRUE

$go = "`nGO`n"
$db.Tables | % { $_.Script($options) | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_TableKey.sql"

# 7. Gerando o script das tabelas com as Keys e Constraints, sem Collation
$options = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions
$options.DriAll = $TRUE
$options.NoCollation = $TRUE

$go = "`nGO`n"
$db.Tables | % { $_.Script($options) | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_TableAll.sql"

Forma resumida para este script se executado dentro do próprio contexto do SQL Server (Jobs, PowerShell do SQL Server ou sqlps.exe):

# Sem referências

# Objetos
sl SQLSERVER:\SQL\LOCALHOST\SQLEXPRESS\Databases\DemoAspNet

$db = get-item .

# 1. Gerando o Script do banco de dados
$db.Script() | Out-File "C:\Temp\DemoAspNet.sql"

# 2. Gerando o Script das tabelas do banco de dados
dir Tables | % { $_.Script() } | Out-File "C:\Temp\DemoAspNet_Tables.sql"

# 3. Script com o GO entre as linhas (Forma 1)
$go = "`nGO`n"
dir Tables | % { $_.Script() | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_Tables.sql"

# 4. Script com o GO entre as linhas (Forma 2)
$go = "
GO
"
$db.Tables | % { $_.Script() | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_Tables.sql"

# 5. Gerando o DROP das tabelas
$options = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions
$options.ScriptDrops = $TRUE

$go = "`nGO`n"
dir Tables | % { $_.Script($options) | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_TableDrop.sql"

# 6. Gerando o script das tabelas com as Primary Keys
$options = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions
$options.DriPrimaryKey = $TRUE

$go = "`nGO`n"
dir Tables | % { $_.Script($options) | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_TableKey.sql"

# 7. Gerando o script das tabelas com as Keys e Constraints, sem Collation
$options = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions
$options.DriAll = $TRUE
$options.NoCollation = $TRUE

$go = "`nGO`n"
dir Tables | % { $_.Script($options) | % { $_ + $go} } | Out-File "C:\Temp\DemoAspNet_TableAll.sql"
