PSSQLite PowerShell Module
=============

This is a PowerShell module for working with SQLite. It uses similar syntax to the [Invoke-Sqlcmd2](https://github.com/RamblingCookieMonster/PowerShell/blob/master/Invoke-Sqlcmd2.ps1) function from Chad Miller et al.

This covers limited functionality; contributions to this function or additional functions would be welcome!

Caveats:
* Minimal testing.
* Today was my first time working with SQLite

## Functionality

Create a SQLite database and table:
* ![Create a SQLite database and table](/Media/Create.png)

Query a SQLite database, using parameters:
* ![Query a SQLite database](/Media/Query.png)

Create a SQLite connection, use it for subsequent queries:
* ![Create a SQLite connection, use it](/Media/Connection.png)

Insert large quantities of data quickly with transactions ([why?](http://www.sqlite.org/faq.html#q19)):

## Instructions

```powershell
# One time setup
# Download the repository
# Unblock the zip
# Extract the PSSQLite folder to a module path (e.g. $env:USERPROFILE\Documents\WindowsPowerShell\Modules\)

#Simple alternative, if you have PowerShell 5, or the PowerShellGet module:
Install-Module PSSQLite

# Import the module.
Import-Module PSSQLite #Alternatively, Import-Module \\Path\To\PSSQLite

# Get commands in the module
Get-Command -Module PSSQLite

# Get help for a command
Get-Help Invoke-SQLiteQuery -Full

# Create a database and a table
$Query = "CREATE TABLE NAMES (fullname VARCHAR(20) PRIMARY KEY, surname TEXT, givenname TEXT, BirthDate DATETIME)"
$DataSource = "C:\Names.SQLite"

Invoke-SqliteQuery -Query $Query -DataSource $DataSource

# View table info
Invoke-SqliteQuery -DataSource $DataSource -Query "PRAGMA table_info(NAMES)"

# Insert some data, use parameters for the fullname and birthdate
$query = "INSERT INTO NAMES (fullname, surname, givenname, birthdate) VALUES (@full, 'Cookie', 'Monster', @BD)"

Invoke-SqliteQuery -DataSource $DataSource -Query $query -SqlParameters @{
full = "Cookie Monster"
BD = (get-date).addyears(-3)
}

# View the data
Invoke-SqliteQuery -DataSource $DataSource -Query "SELECT * FROM NAMES"

#Build up some fake data to bulk insert, convert it to a datatable
$DataTable = 1..10000 | %{
[pscustomobject]@{
fullname = "Name $_"
surname = "Name"
givenname = "$_"
BirthDate = (Get-Date).Adddays(-$_)
}
} | Out-DataTable

#Insert the data within a single transaction (SQLite is faster this way)
Invoke-SQLiteBulkCopy -DataTable $DataTable -DataSource $DataSource -Table Names -NotifyAfter 1000 -verbose

#View all the data!
Invoke-SqliteQuery -DataSource $DataSource -Query "SELECT * FROM NAMES"
```

## Notes

This isn't a fully featured module or function.

I'm planning to write about using SQL from a systems administrator or engineer standpoint. I personally stick to [MSSQL and Invoke-Sqlcmd2](https://ramblingcookiemonster.wordpress.com/2014/03/12/sql-for-powershell-for-sql-newbies/), but want to provide an abstracted means to perform this without the prerequisite of an accessible MSSQL instance.

Check out Jim Christopher's [SQLite PowerShell Provider](https://psqlite.codeplex.com/). It offers more functionality and flexibility than this repository.

Credit to Chad Miller, Justin Dearing, Paul Bryson, Joel Bennett, and Dave Wyatt for the code carried over from Invoke-Sqlcmd2.
