PsAdoNet

The goal of PsAdoNet is to encourage the development of composeable ADO.NET solutions using PowerShell. Adhering to Powershell's core philosophy of doing one thing and doing it well, the steps of interacting with a data source are broken into small tools, as opposed to a single-serving function.

Getting Started

# From PowerShell Gallery
Install-Module -Name PSAdoNet

# OR Manual download & installing for a specific user
Copy-Item -Path {rest of path}\PsAdoNet `
          -Destination $HOME\Documents\PowerShell\Modules

# Close & re-open shell window
# Verify it worked
Get-Command -Module PsAdoNet

For more detail installation instructions see the official docs

Quick Start

A simple example demonstrating the execution of a simple query against a SQL Server Instance.

# Create a DbConnection
$conn = New-SqlServerConnection -ServerInstance SQLVM01

# Create a DbCommand
$cmd = New-DbCommand -Query "SELECT * FROM Products"

# Invoke query and display result
$cmd | Invoke-DbCommand -DataTable | Format-Table

# Properly dispose of objects
Close-Resource $conn, $cmd

An example demonstrating efficient and practical ETL pattern using SqlBulkCopy and an IDataReader.

$source = New-SqlServerConnection -ServerInstance SQLVM01 -Database Northwind
$dest = New-SqlServerConnection -ServerInstance SQLVM02 -Database Northwind

$rd = $source | New-DbCommand -Query "SELECT * FROM Products" | Invoke-DbCommand -Reader
$bcp = Invoke-SqlServerBulkCopy -DataReader $rd -Connection $dest -Table "Products" -BatchSize 5000 -BulkCopyTimeout 30

Close-Resource $source, $dest, $rd, $bcp

An example using ConvertTo-DataTable to bulk copy an ad-hoc list of objects to a SQL Server database.

$dest = New-SqlServerConnection -ServerInstance SQLVM02 -Database ProcessDb

$dt = Get-Process | Select-Object -First 5 -Property Id, Description | ConvertTo-DataTable
$bcp = Invoke-SqlServerBulkCopy -DataTable $dt -Connection $dest -Table "Process" -ColumnMappings @{Id = "Id"; Description = "Description" }

Close-Resource $dest, $rd, $bcp

Find a bug?

There's an issue for that.
