How to connect to and populate SQL database using Powershell - sql

Question

I want to write an application that talks to a database. The databases are created through phpmyadmin interface. I can talk to these fine through php. What I would like is to populate these databases using a powershell script.
How do I connect to the database ? How do I populate a database ? I can't seem to find any good starting points.

Answer 2

Here's a function to handle this type of task
function Invoke-SQL
{
param (
[string]$server,
[string]$database,
[string]$Query
)
$connectionString = "Data Source=$server; " +
"Integrated Security=SSPI; " +
"Initial Catalog=$database"
$connection = new-object
system.data.SqlClient.SQLConnection($connectionString)
$command = new-object system.data.sqlclient.sqlcommand($Query, $connection)
$connection.Open()
$adapter = New-Object System.Data.sqlclient.sqlDataAdapter $command
# Use these to populate info #
$dataset = New-Object System.Data.DataSet
$adapter.Fill($dataSet) | Out-Null
$connection.Close()
# displays info #
$dataSet.Tables
}
Here's an example of updating the SQL Database
Invoke-SQL -server 'server' -database 'database' -Query "UPDATE [database].[dbo].[Local] SET Field1 = '$InfoForField1', Field2 = '$InfoForField2'"
You can do whatever you need using this method, as long as you know your SQL queries and how to populate the varaibles with the correct information that you need.
