Pass username fro MySQL query into variable with field name meta data

Hi All,

I am new Powershell and MySQL and having some trouble with passing a username, returned by a query to a MySQL server, into a variable without the meta data of the field name being copied also.

The query responds with the following:

Login
-----
test1
 

I want "test1" only to pass into variable $test. However I cannot work out the correct way to do this.

I am importing a module that I have created to store the MySQL query so that I can simple call the connection and pass a query to it in a separate script, the module is call mysqlconnection.psm1 and contains the following:

Function Run-MySQLQuery {

    Param(
        [Parameter(
            Mandatory = $true,
            ParameterSetName = '',
            ValueFromPipeline = $true)]
            [string]$query,   
        [Parameter(
            Mandatory = $true,
            ParameterSetName = '',
            ValueFromPipeline = $true)]
            [string]$connectionString
        )
    Begin {
        Write-Verbose "Starting Begin Section"        
    }
    Process {
        Write-Verbose "Starting Process Section"
        try {
            # load MySQL driver and create connection
            Write-Verbose "Create Database Connection"
            # You could also could use a direct Link to the DLL File
            # $mySQLDataDLL = "C:\Program Files (x86)\MySQL\MySQL Connector Net 6.9.3\Assemblies\v4.5\MySQL.Data.dll"
            # [void][system.reflection.Assembly]::LoadFrom($mySQLDataDLL)
            [void][System.Reflection.Assembly]::LoadWithPartialName("MySql.Data")
            $connection = New-Object MySql.Data.MySqlClient.MySqlConnection
            $connection.ConnectionString = $ConnectionString
            Write-Verbose "Open Database Connection"
            $connection.Open()
            # Run MySQL Querys
            Write-Verbose "Run MySQL Querys"
            $command = New-Object MySql.Data.MySqlClient.MySqlCommand($query, $connection)
            $dataAdapter = New-Object MySql.Data.MySqlClient.MySqlDataAdapter($command)
            $dataSet = New-Object System.Data.DataSet
            $recordCount = $dataAdapter.Fill($dataSet, "data")
            $dataSet.Tables["data"] | Format-Table
        }        
        catch {
            Write-Host "Could not run MySQL Query" $Error[0]    
        }    
        Finally {
            Write-Verbose "Close Connection"
            $connection.Close()
        }
    }
    End {
        Write-Verbose "Starting End Section"
    }
}

export-modulemember Run-MySQLQuery

This module is called in another script with the following:

$username = "test1"

Import-Module ActiveDirectory
Import-Module C:\Windows\System32\WindowsPowerShell\v1.0\Modules\MySQL\mysqlconnection_test.psm1

$test = run-MySQLQuery -ConnectionString "Server=test;Uid=root;Pwd=Password123;database=test;" -Query "select login from usr_data where usr_id = 226"

As state previously $test now contains:

Login
-----
test1

I am sure I am missing something simply, but I am stumped so far.

Powershell and MySQL are not part of my standard expertise so any help with this would be greatly appreciated!
