function Find-DbaView { <# .SYNOPSIS Returns all views that contain a specific case-insensitive string or regex pattern. .DESCRIPTION This function can either run against specific databases or all databases searching all user or user and system views. .PARAMETER SqlInstance SQLServer name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input .PARAMETER SqlCredential PSCredential object to connect as. If not specified, current Windows login will be used. .PARAMETER Database The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto-populated from the server .PARAMETER Pattern String pattern that you want to search for in the view textbody .PARAMETER IncludeSystemObjects By default, system views are ignored but you can include them within the search using this parameter. Warning - this will likely make it super slow if you run it on all databases. .PARAMETER IncludeSystemDatabases By default system databases are ignored but you can include them within the search using this parameter .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Author: Cláudio Silva (@ClaudioESSilva) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Find-DbaView .EXAMPLE Find-DbaView -SqlInstance DEV01 -Pattern whatever Searches all user databases views for "whatever" in the textbody .EXAMPLE Find-DbaView -SqlInstance sql2016 -Pattern '\w+@\w+\.\w+' Searches all databases for all views that contain a valid email pattern in the textbody .EXAMPLE Find-DbaView -SqlInstance DEV01 -Database MyDB -Pattern 'some string' -Verbose Searches in "mydb" database views for "some string" in the textbody .EXAMPLE Find-DbaView -SqlInstance sql2016 -Database MyDB -Pattern RUNTIME -IncludeSystemObjects Searches in "mydb" database views for "runtime" in the textbody #> [CmdletBinding()] Param ( [parameter(Position = 0, Mandatory = $true, ValueFromPipeline = $True)] [Alias("ServerInstance", "SqlServer", "SqlServers")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [parameter(Mandatory = $true)] [string]$Pattern, [switch]$IncludeSystemObjects, [switch]$IncludeSystemDatabases, [switch]$Silent ) begin { $sql = "SELECT OBJECT_SCHEMA_NAME(vw.object_id) as ViewSchema, vw.name, m.definition as TextBody FROM sys.sql_modules m, sys.views vw WHERE m.object_id = vw.object_id" if (!$IncludeSystemObjects) { $sql = "$sql AND vw.is_ms_shipped = 0" } $everyservervwcount = 0 } process { foreach ($Instance in $SqlInstance) { try { Write-Message -Level Verbose -Message "Connecting to $Instance" $server = Connect-SqlInstance -SqlInstance $Instance -SqlCredential $SqlCredential } catch { Write-Message -Level Warning -Message "Failed to connect to: $Instance" continue } if ($server.versionMajor -lt 9) { Write-Message -Level Warning -Message "This command only supports SQL Server 2005 and above."
