Test Database Connectivity

by

Use the SqlConnection class to test a connection. You don’t have to load any SQL assemblies.

Helper function:

function Test-SQLConnection
{    
    [OutputType([bool])]
    Param
    (
        [Parameter(Mandatory=$true,
                    ValueFromPipelineByPropertyName=$true,
                    Position=0)]
        $ConnectionString
    )
    try
    {
        $sqlConnection = New-Object System.Data.SqlClient.SqlConnection $ConnectionString;
        $sqlConnection.Open();
        $sqlConnection.Close();

        return $true;
    }
    catch
    {
        return $false;
    }
}

Usage example:

Test-SQLConnection "Data Source=localhost;database=myDB;User ID=myUser;Password=myPassword;"
