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 The target SQL Server instance or instances. This can be a collection and receive pipeline input .PARAMETER SqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .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 text body .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 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. .NOTES Tags: View Author: Claudio Silva (@ClaudioESSilva) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Find-DbaView .EXAMPLE PS C:\> Find-DbaView -SqlInstance DEV01 -Pattern whatever Searches all user databases views for "whatever" in the text body .EXAMPLE PS C:\> Find-DbaView -SqlInstance sql2016 -Pattern '\w+@\w+\.\w+' Searches all databases for all views that contain a valid email pattern in the text body .EXAMPLE PS C:\> Find-DbaView -SqlInstance DEV01 -Database MyDB -Pattern 'some string' -Verbose Searches in "mydb" database views for "some string" in the text body .EXAMPLE PS C:\> Find-DbaView -SqlInstance sql2016 -Database MyDB -Pattern RUNTIME -IncludeSystemObjects Searches in "mydb" database views for "runtime" in the text body #> [CmdletBinding()] param ( [parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [object[]]$Database, [object[]]$ExcludeDatabase, [parameter(Mandatory)] [string]$Pattern, [switch]$IncludeSystemObjects, [switch]$IncludeSystemDatabases, [switch]$EnableException ) 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 { $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."
