function Get-DbaDbStoredProcedure {
<#
    .SYNOPSIS
        Gets database Stored Procedures
 
    .DESCRIPTION
        Gets database Stored Procedures
 
    .PARAMETER SqlInstance
        The target SQL Server instance or instances
 
    .PARAMETER SqlCredential
        Allows you to login to SQL Server using alternative credentials
 
    .PARAMETER Database
        To get Stored Procedures from specific database(s)
 
    .PARAMETER ExcludeDatabase
        The database(s) to exclude - this list is auto populated from the server
 
    .PARAMETER ExcludeSystemSp
        This switch removes all system objects from the Stored Procedure collection
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
