function Invoke-DBODeployment { <# .SYNOPSIS Deploys extracted dbops package from the specified location .DESCRIPTION Deploys an extracted dbops package or plain text scripts with optional parameters. Uses a table specified in SchemaVersionTable parameter to determine scripts to run. Will deploy all the builds from the package that previously have not been deployed. .PARAMETER PackageFile Path to the dbops package file (usually, dbops.package.json). .PARAMETER InputObject DBOpsPackage object to deploy. Supports pipelining. .PARAMETER ScriptPath A collection of script files to deploy to the server. Accepts Get-Item/Get-ChildItem objects and wildcards. Will recursively add all of the subfolders inside folders. See examples if you want only custom files to be added. During deployment, scripts will be following this deployment order: - Item order provided in the ScriptPath parameter - Files inside each child folder (both folders and files in alphabetical order) - Files inside the root folder (in alphabetical order) Aliases: SourcePath .PARAMETER SqlInstance Database server to connect to. SQL Server only for now. Aliases: Server, SQLServer, DBServer, Instance .PARAMETER Database Name of the database to execute the scripts in. Optional - will use default database if not specified. .PARAMETER DeploymentMethod Choose one of the following deployment methods: - SingleTransaction: wrap all the deployment scripts into a single transaction and rollback whole deployment on error - TransactionPerScript: wrap each script into a separate transaction; rollback single script deployment in case of error - NoTransaction: deploy as is Default: NoTransaction .PARAMETER ConnectionTimeout Database server connection timeout in seconds. Only affects connection attempts. Does not affect execution timeout. If 0, will wait for connection until the end of times. Default: 30 .PARAMETER ExecutionTimeout Script execution timeout. The script will be aborted if the execution takes more than specified number of seconds. If 0, the script is allowed to run until the end of times. Default: 0 .PARAMETER Encrypt Enables connection encryption. .PARAMETER Credential PSCredential object with username and password to login to the database server. .PARAMETER UserName An alternative to -Credential - specify username explicitly .PARAMETER Password An alternative to -Credential - specify password explicitly .PARAMETER SchemaVersionTable A table that will hold the history of script execution. This table is used to choose what scripts are going to be run during the deployment, preventing the scripts from being execured twice. If set to $null, the deployment will not be tracked in the database. That will also mean that all the scripts and all the builds from the package are going to be deployed regardless of any previous deployment history. Default: dbo.SchemaVersions .PARAMETER Silent Will supress all output from the command. .PARAMETER Variables Hashtable with variables that can be used inside the scripts and deployment parameters. Proper format of the variable tokens is #{MyVariableName} Can also be provided as a part of Configuration hashtable: -Configuration @{ Variables = @{ Var1 = ...; Var2 = ...}} Will augment and/or overwrite Variables defined inside the package. .PARAMETER OutputFile Log output into specified file. .PARAMETER Append Append output to the -OutputFile instead of overwriting it. .PARAMETER Confirm Prompts to confirm certain actions .PARAMETER WhatIf Shows what would happen if the command would execute, but does not actually perform the command .EXAMPLE # Start the deployment of the extracted package from the current folder Invoke-DBODeployment .EXAMPLE # Start the deployment of the extracted package from the current folder using specific connection parameters Invoke-DBODeployment -SqlInstance 'myserver\instance1' -Database 'MyDb' -ExecutionTimeout 3600 .EXAMPLE # Start the deployment of the extracted package using custom logging parameters and schema tracking table Invoke-DBODeployment .\Extracted\dbops.package.json -SchemaVersionTable dbo.SchemaHistory -OutputFile .\out.log -Append .EXAMPLE #
