#ValidationTags#CodeStyle,Messaging,FlowControl,Pipeline# function New-DbaDatabase { <# .SYNOPSIS Creates a new database .DESCRIPTION This command creates a new database. It allows creation with multiple files, and sets all growth settings to be fixed size rather than percentage growth. .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Name The name of the new database or databases to be created. .PARAMETER DataFilePath The location that data files will be placed, otherwise the default SQL Server data path will be used. .PARAMETER LogFilePath The location the log file will be placed, otherwise the default SQL Server log path will be used. .PARAMETER Collation The database collation, if not supplied the default server collation will be used. .PARAMETER Recoverymodel The recovery model for the database, if not supplied the recovery model from the model database will be used. .PARAMETER Owner The login that will be used as the database owner. .PARAMETER PrimaryFilesize The size in MB for the Primary file. If this is less than the primary file size for the model database, then the model size will be used instead. .PARAMETER PrimaryFileGrowth The size in MB that the Primary file will autogrow by. .PARAMETER PrimaryFileMaxSize The maximum permitted size in MB for the Primary File. If this is less the primary file size for the model database, then the model size will be used instead. .PARAMETER LogSize The size in MB that the Transaction log will be created. .PARAMETER LogGrowth The amount in MB that the log file will be set to autogrow by. .PARAMETER SecondaryFileCount The number of files to create in the Secondary filegroup for the database. .PARAMETER SecondaryFilesize The size in MB of the files to be added to the Secondary filegroup. Each file added will be created with this size setting. .PARAMETER SecondaryFileMaxSize The maximum permitted size in MB for the Secondary data files to grow to. Each file added will be created with this max size setting. .PARAMETER SecondaryFileGrowth The amount in MB that the Secondary files will be set to autogrow by. Use 0 for no growth allowed. Each file added will be created with this growth setting. .PARAMETER DefaultFileGroup Sets the default file group. Either primary or secondary. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .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: Database Author: Matthew Darwin (@evoDBA, naturalselectiondba.wordpress.com) | Chrissy LeMaire (@cl) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/New-DbaDatabase .EXAMPLE New-DbaDatabase -SqlInstance sql1 Creates a randomly named database (random-N) on instance sql1 .EXAMPLE New-DbaDatabase -SqlInstance sql1 -Name dbatools, dbachecks Creates a database named dbatools and a database named dbachecks on sql1 .EXAMPLE New-DbaDatabase -SqlInstance sql1, sql2, sql3 -Name multidb, multidb2 -SecondaryFilesize 20 -SecondaryFileGrowth 20 -LogSize 20 -LogGrowth 20 Creates two databases, multidb and multidb2, on 3 instances (sql1, sql2 and sql3) and sets the secondary data file size to 20MB, the file growth to 20MB and the log growth to 20MB for each .EXAMPLE New-DbaDatabase -SqlInstance sql1 -Name nondefault -DataFilePath M:\Data -LogFilePath 'L:\Logs with spaces' -SecondaryFileCount 2 Creates a database named nondefault and places data files in in the M:\data directory and log files in "L:\Logs with spaces".
