Export MSSQL schema with PowerShell. This script will export your schema definitions for tables, stored procs, triggers, functions and views to .sql files
<#
.SYNOPSIS
Export schema for a database
.DESCRIPTION
This script will export your schema definitions for tables, stored procs, triggers, functions and views to .sql files
.PARAMETER ServerName
database server instance
.PARAMETER DatabaseName
You can specify a database name to only export single DB schema
.PARAMETER ScriptPath
directory where scripts will be dumped to. Relative paths are also ok
.PARAMETER RecursiveMode
Use this switch to export schema for ALL user databases on a servername
.EXAMPLE
Dump scripts for single database:
powershell ExportSchema.ps1 "SERVERNAME" "DATABASE" "C:\<YourOutputPath>"
.\ExportSchema.ps1 -ServerName Contososerver -DatabaseName Adventureworks -ScriptPath C:\export
.EXAMPLE
----
.NOTES
New features:
- created RecursiveMode to allow dumping all user databases on a server
- added commandline parameters, so can be called as a powershell commandlet
- changed logic to prevent creating of empty script files
- change logic to filter out encrypted functions/procedures, so no need to check for null script data
