<# .SYNOPSIS Clear out data for a table inside the bacpac file .DESCRIPTION Remove all data for a table inside a bacpac file, before restoring it into your SQL Server / Azure SQL DB It will extract the bacpac file as a zip archive, locate the desired table and remove the data that otherwise would have been loaded It will re-zip / compress a new bacpac file for you .PARAMETER Path Path to the bacpac file that you want to work against It can also be a zip file .PARAMETER TableName Name of the table that you want to delete the data for Supports an array of table names If a schema name isn't supplied as part of the table name, the cmdlet will prefix it with "dbo." .PARAMETER OutputPath Path to where you want the updated bacpac file to be saved .EXAMPLE PS C:\> Clear-D365TableDataFromBacpac -Path "C:\Temp\AxDB.bacpac" -TableName "BATCHJOBHISTORY" -OutputPath "C:\Temp\AXBD_Cleaned.bacpac" This will remove the data from the BatchJobHistory table from inside the bacpac file. It uses "C:\Temp\AxDB.bacpac" as the Path for the bacpac file. It uses "BATCHJOBHISTORY" as the TableName to delete data from. It uses "C:\Temp\AXBD_Cleaned.bacpac" as the OutputPath to where it will store the updated bacpac file. .EXAMPLE PS C:\> Clear-D365TableDataFromBacpac -Path "C:\Temp\AxDB.bacpac" -TableName "dbo.BATCHHISTORY","BATCHJOBHISTORY" -OutputPath "C:\Temp\AXBD_Cleaned.bacpac" This will remove the data from the BatchJobHistory table from inside the bacpac file. It uses "C:\Temp\AxDB.bacpac" as the Path for the bacpac file. It uses "dbo.BATCHHISTORY","BATCHJOBHISTORY" as the TableName to delete data from. It uses "C:\Temp\AXBD_Cleaned.bacpac" as the OutputPath to where it will store the updated bacpac file. .NOTES Tags: Bacpac, Servicing, Data, Deletion, SqlPackage Author: Mötz Jensen (@Splaxi) #> function Clear-D365TableDataFromBacpac { [CmdletBinding()] param ( [Parameter(Mandatory = $true)] [Alias('File')] [Alias('BacpacFile')] [string] $Path, [Parameter(Mandatory = $true)] [string[]] $TableName, [Parameter(Mandatory = $true)] [string] $OutputPath ) begin { if (-not (Test-PathExists -Path $Path -Type Leaf)) { return } $compressPath = "" $newFilename = "" if ($OutputPath -like "*.bacpac") { $compressPath = $OutputPath.Replace(".bacpac", ".zip") $newFilename = Split-Path -Path $OutputPath -Leaf } else { $compressPath = $OutputPath } if (-not (Test-PathExists -Path $compressPath -Type Leaf -ShouldNotExist)) { Write-PSFMessage -Level Host -Message "The <c='em'>$compressPath</c> already exists.
