Script SQL Server Objects with PowerShell


export_boxScripting SQL Server objects manually through the SQL Server Management Studio can be a tedious task. Last week I published a script to export database objects with PowerShell. I wanted to take this a little further and create a solution to export SQL Server objects as well.

Because this would be a nice addition to the PSSQLLib module, this function is also included in the library from today.

How it works

The function works by selecting all the different server objects needed and loops through the list to export to a specific directory of the type of object.

The script will export the following types of objects:

  • Jobs
  • Linked Servers
  • Logins
  • Server Roles
  • Triggers
  • Mail

You can exclude objects by specifying a include parameters. For instance, if you want to exclude jobs:

Export-SQLServerObject -inst 'yourinstance' -path 'yourpath' -includejobs $false
Export-SQLServerObject -inst 'yourinstance' -path 'yourpath' -includejobs 0

The same method works for the rest of the objects by using the other parameters.

The code

The finished code look like this:

    Generates export files of SQL Server objects
    This function will return generate an export file of SQL Server objects to a .sql file.
    This includes server roles, logins, linked servers, triggers, database mail and jobs.
.PARAMETER  instance
    This is the instance that needs to be connected
    Path to export to
    This is the port of the instance that needs to be used
.PARAMETER includetimestamp
    Boolean to include a timestamp directory to export to
.PARAMETER includeroles
    Boolean to include or exclude server roles. Can be value $false/$true or 0/1.
.PARAMETER includelogins
    Boolean to include or exclude logins. Can be value $false/$true or 0/1.
.PARAMETER includelinkedservers
    Boolean to include or exclude linked servers. Can be value $false/$true or 0/1.
.PARAMETER includetriggers
    Boolean to include or exclude triggers. Can be value $false/$true or 0/1.
.PARAMETER includemail
    Boolean to include or exclude database mail. Can be value $false/$true or 0/1.
.PARAMETER includejobs
    Boolean to include or exclude jobs. Can be value $false/$true or 0/1.

The Result

The result is a script that will export all your objects to “.sql” files. The result of the execution of the script can be seen below:
