Gerar scripts de bases


Esse script é uma modificação de um script do simple-talk apenas adicionar a opção de função para facilitar a vida

o importante para este script funcionar é:

  1. criar um diretório com o nome Script-DBObjectsIntoFolders dentro do diretório C:\Windows\System32\WindowsPowerShell\v1.0\Modules\
  2. Salvar este script com o nome Script-DBObjectsIntoFolders.psm1
  3. Usando o powershell digitar import-module Script-DBObjectsIntoFolders

 


#https://www.simple-talk.com/sql/database-administration/automated-script-generation-with-powershell-and-smo/

function global:Script-DBObjectsIntoFolders([string]$server, [string]$dbname, [string]$DirectoryToSave){

# set "Option Explicit" to catch subtle errors
set-psdebug -strict
$DirectoryToSaveTo=$DirectoryToSave # local directory to save build-scripts to
$servername=$server # server name and instance
$Database=$dbname # the database to copy from
$ErrorActionPreference = "stop" # you can opt to stagger on, bleeding, if an error occurs
Trap {
# Handle the error
$err = $_.Exception
write-host $err.Message
while( $err.InnerException ) {
$err = $err.InnerException
write-host $err.Message
};
# End the script.
break
}

Catch [system.exception]{

return
}
}
